Abstract

Aseel and Kadaknath are two of the most important native chicken breeds of India. Aseel having an aggressive behavior and fighting ability is well known for its meat qualities and Kadaknath is popular for its black meat and eggs having proven medicinal and added nutritional values. The present study was designed to evaluate the effect of genetic and non genetic factors on growth and layer economic traits and compare the estimated phenotypic and genetic parameters in the two indigenous breeds. Single generation data was collected from Aseel and Kadaknath birds reared under intensive system in Desi Fowl Unit of ICAR-Central Avian Research Institute, Izatnagar, Uttar Pradesh, India. The least square means of growth traits revealed a higher body weight gain at 20 (BW20) and 40 (BW40) weeks in Aseel i.e. 1036.02 ± 13.64 g and 1561.32 ± 19.67 g respectively compared to Kadaknath measuring 602.53 ± 19.73 g and 1158.79 ± 23.44 g respectively. Both the breeds took almost same time to reach sexual maturity. Least square means of egg weight at 28 (EW28) and 40 (EW40) weeks, egg production up to 40 weeks (EP40) were 38.22 ± 0.72 g, 43.68 ± 0.49 g, 40.88 ± 2.70, respectively in Aseel and 33.68 ± 0.79 g, 40.06 ± 0.73 g and 35.82 ± 2.13, respectively in Kadaknath. All the concerned traits were found to have medium to high heritability suggesting scope for further improvement in growth and production traits in both the breeds via proper selection and mating program.

Introduction
Poultry industry is one amongst the fastest growing industries in India. India is the second
largest poultry market in the world. It produces about 122.09 billion eggs (with an average
growth rate of 6.70%, BAHFS, 2021-22) and 4.34 million tonnes of poultry meat (growing @
8-10%, BAHFS, 2020). Total meat production (including poultry) in the country is 8.80
million tonnes in 2021-22.
Globally, India ranks third in egg production and fifth in broiler production. The egg and
broiler production has been rising @ 8-10% per annum. Total poultry population in India is
851.81million (20th livestock census) and is at seventh rank across the globe.
The demand of poultry products in the market is increasing day-by-day with the increase in
human population. In developed countries, the per capita consumption of eggs is 240 and
chicken meat is 20 kg per annum. As per National Institute of Nutrition, India, the
recommended per capita consumption of poultry eggs is 182 eggs and that of meat is 11.5 kg
but the actual consumption is 89 eggs and 6.52 kg meat only. This wide margin between the
two signifies that still the poultry industry is far from saturation and also there is a long way to
bridge the gap between the developed and developing countries. Poultry sector contributes
about Rs. 125 lakh Crores accounting for about 1% of the national GDP and about 14% of the
Livestock GDP.
The local/ indigenous breeds contribute maximum poultry genetic resources playing an
important role in developing countries like India. Indigenous chickens comprise a greater part
of the national flocks in India. Even though their growth rates and egg production are low,
they are generally better in disease resistance and comparatively have higher levels of
performance even under poor nutrition and high environmental temperatures than the
commercial strains under village systems. It has been reported that Aseel and Kadaknath
native chicken breeds had higher immuno-competence than White Leghorn chicken (Kokate et
al., 2017) [10].

The original home tract of Aseel is Andhra Pradesh. It is a
source of income for the tribals. Aseel is known for its
delicious and flavored meat. Eggs are generally kept for
hatching and are not eaten or sold. Aseel is popularly a game
bird and is well known for its hostility, high stamina, majestic
gait and fighting qualities. The home tract of Kadaknath is
Jhabua and Dhar districts of Madhya Pradesh and adjoining
districts of Rajasthan and Gujarat. Its flesh is a black delicacy
with medicinal values. The tribals treat chronic diseases in
human beings by the blood of Kadaknath and use its meat as
an aphrodisiac. The meat and eggs of Kadaknath are a rich
source of protein and iron. The annual egg production is
around 80 eggs.
The low productivity of the indigenous chicken breeds has
attracted the interest of researchers. Nowadays, the
indigenous chicken breeds are being genetically improved for
their productivity so as to make them economically viable.
Further, these improved indigenous breeds are being used for
developing crosses for backyard poultry farming. However,
not many studies have been conducted on Aseel and
Kadaknath regarding their growth and egg production
performance. Hence, genetic evaluation and comparative
studies of Aseel and Kadaknath is much needed. Moreover,
the knowledge of genetic and non genetic factors affecting the
growth, production and reproduction of birds along with
estimation of genetic and phenotypic parameters helps in pure
line selection and cross bred production which is mainly used
in poultry breeding.
Material and Methods
Data
The required data were recorded on 180 pedigreed birds of
Aseel and 120 pedigreed birds of Kadaknath native chickens,
maintained at the ICAR- Central Avian Research Institute’s
Desi Farm unit, for the proposed study. The data generated
was from a single generation. Traits were recorded from
individual birds which were kept in separate cages and were
identified by wing and leg band numbers. Standard feeding
and management was practiced along with proper vaccination
schedule being followed in the farm.
Traits recorded
The growth and layer economic traits such as age at sexual
maturity (ASM) for individual pullet calculated as the number
of days from hatching to the laying of the first egg, body
weights (g) of all the pullets at 20 (BW20) and 40 (BW40)
weeks of age, average of egg weights of three consecutive
days for each pullet at 28th (EW28) and 40th (EW40) weeks of
age, individual daily egg production of each pullet up to 40
weeks of age (EP 40) were recorded.
Statistical analysis
Data recorded on growth and egg production traits were
analyzed using mixed model least squares analysis of variance
and maximum likelihood program (Harvey, 1990). Sire was
taken as random effect and hatch as fixed effect wherever
applicable in the model. Following statistical model was used:
Yijk= µ + Si + Hj + eijk
Where
Yijk =Value of a trait measured on kth individual belonging to
ith sire and jth hatch.
µ = Population mean
Si = Random effect of ith sire
Hj = fixed effect of hatch (j= 1 in case of Aseel, j=2 in case of
Kadaknath)
eijk = Random error associated with mean zero and variance
σ2e.
The chicks were also evaluated for the inheritance pattern of
all the recorded traits. Genetic and phenotypic parameters of
body weights and layer economic traits were estimated using
paternal half-sib correlation method (Becker, 1975).
Results
In Aseel females, the least squares means of growth traits viz.,
BW20, BW40 and production traits viz., ASM, EW28, EW40
and EP40 were 1036.02 ± 13.64g, 1561.32 ± 19.67g, 214.39 ±
2.22 days, 38.22 ± 0.72g, 43.68 ± 0.49g and 40.88 ± 2.70
eggs, respectively. Least squares analysis of variance of all
the growth and production traits of Aseel native chicken are
presented in table 1. The overall least squares means and
standard errors of all the considered traits are presented in
table 2. Sire was found to have a significant (P≤0.05) effect
on BW20 and EP40 but not on other traits. The hatch effect
was not taken into account as all the experimental birds
belong to same hatch.
In Kadaknath females, the estimated least square means of
growth traits viz., BW20, BW40 and production traits viz.,
ASM, EW28, EW40 and EP40 were 602.53 ± 19.73 g,
1158.79 ± 23.44 g, 213.04 ± 2.80 days, 33.68 ± 0.79 g, 40.06
± 0.73 g and 35.82 ± 2.13 eggs respectively. The least squares
analysis of variance of all the considered traits are represented
in table 3. The least squares means along with their standard
errors are depicted in table 4. Hatch and sire were found to
have non-significant effects on all the growth as well as layer
economic traits. In the present study, Aseel native chicken
breed showed higher body weight at twenty and forty weeks
of age compared to that of Kadaknath native chicken breed.
The heritability estimates for both BW20 and BW40 were
found to be higher in magnitude in both the breeds viz., 0.81 ±
0.31 and 0.75 ± 0.23, respectively in Aseel and 0.81 ± 0.39
and 0.79 ± 0.34, respectively in Kadaknath. ASM was found
to have higher heritability in Aseel (0.42 ± 0.25) as compared
to Kadaknath (0.24 ± 0.11). Egg weights showed higher
heritabilities whereas egg production up to forty weeks
showed medium heritability in both Aseel as well as
Kadaknath birds. For Aseel birds, heritabilities ± standard
errors along with phenotypic and genetic correlations among
the concerned traits are shown in table 5. The same
parameters are represented in table 6 for Kadaknath birds
under study. In present investigation, the genetic correlation
among the various traits lies within the range of -0.97 ± 0.16
to 0.83 ± 0.66 in Aseel birds and -0.83 ± 0.25 to 0.87 ± 0.11
in Kadaknath birds, although no definite pattern of genetic
correlation was observed amongst the traits. The phenotypic
correlation ranges from -0.60 (among ASM and EP40) to 0.57
(among BW20 and BW40) and from -0.58 (among ASM and
BW20) to 0.50 (among BW20 and BW40) in Aseel and
Kadaknath birds respectively.

Discussion
Growth and layer production traits
Comparatively higher estimates of BW20 and BW40 i.e.
1381.4 ± 18.2 g and 1704.4 ± 23.2 g respectively were
reported in Aseel by Rajkumar et al. (2017) [14]. Thangadurai
et al. (2020) [16] reported BW20 and BW40 as 820 g and 1400
g respectively in TANUVAS Aseel which were lower than
the present estimates in Aseel native chicken. Haunshi et al.
(2011) [6] reported the BW20 and BW 40 as 769.11 ± 12.41 g
and 1,321.6 ± 18.4 g respectively in Kadaknath, the estimates
being higher than the one estimated in the present study.
Similar results were obtained by Bhagora et al. (2022) [1]
where they reported the higher estimates of BW20 and BW40
week as 1247.07 ± 30.31 g and 1520.44 b ± 39.85 g
respectively in Kadaknath chicken breed. The differences
found in the estimates of various body weights as reported in
different reports might be due to the different genetic
background of the stocks used during the studies and also due
to differences in the various environmental factors like feed,
heat and cold stress management, disease condition,
vaccination schedule etc followed during the experiment.
Haunshi et al. (2012) [7] reported a comparatively lower ASM
i.e. 174 ± 0.9 days in Aseel birds. Rajkumar et al. (2017) [14],
in their study found ASM of Aseel birds as 214.0 ± 6.0 days.

The Pharma Innovation Journal https://www.thepharmajournal.com
The estimate is close to the estimate obtained in present study.
Yet another study by Dalal et al. (2019) [4], reported ASM as
182.66 ± 1.98 days in Aseel which is lower than that of the
present estimate. Miazi et al. (2020) [11] reported ASM as 210
days in Aseel birds. Lower ASM estimate than the present
estimate in Kadaknath Breed were reported by Dalal et al.
(2019) [4] and Bhagora et al. (2022) [1] as 210 days, 169.83 ±
0.95 days and 195.22 ± 3.62 respectively. The different
genetic groups reared and selected in different environments
might be the reason for differences in the estimates of age at
sexual maturity as reported in different reports.
Haunshi et al. (2012) [7] reported egg weight at 28 weeks and
40 weeks as 42.57±0.30 g and 47.57±0.34 g respectively in
Aseel which are higher than the estimates of present study.
Rajkumar et al. (2017) [14] reported a lower egg weight at 40
weeks i.e. 38.8 ± 0.6 g as obtained in their study on Aseel
birds. Comparatively higher estimates of EW28 and EW40
were reported by Haunshi et al. (2019) [8] i.e. 43.4±0.23 g,
48.9±0.28g respectively in PD-4 Aseel. In Kadaknath higher
estimates of EW 28 and EW40 compared to the one obtained
in present study were reported by Haunshi et al. (2012) [7] as
36.02±0.33 g and 46.68± 0.71 g respectively. Almost similar
i.e. 41.99 ± 0.29 g EW40 was reported by Dalal et al. (2019)
[4]. Bhagora et al. (2022) [1] reported higher EW28 and EW40
as 41.56±0.19 g and 41.06 ± 1.83 g. Variations in the weights
of egg at different ages might be attributed to genetically
variable stocks used in the study along with the differences in
the observed age at sexual maturity of these stocks in the
experiments.
Haunshi et al. (2011) [6] and Rajkumar et al. (2017) [14]
reported EP40 in Aseel as 36.23 eggs and 18.0 ± 1 eggs
respectively, lower than the estimate of present study.
Comparatively higher estimate of EP40 in Aseel was reported
by Dalal et al. (2019) [4] viz. 64.89 ± 2.10 eggs. Similar result
as that of present study was reported by Chitra (2021) in
TANUVAS Aseel as 42.5±0.32 eggs. Chatterjee et al. (2010),
Haunshi et al. (2011) [6], Haunshi et al. (2012) [7] and Dalal et
al. (2019) [4] reported EP40 in Kadaknath chicken as 44.68
eggs, 49.40 eggs, 62.39 eggs and 55.48 ± 1.22 eggs
respectively which are higher than the present estimates of
EP40 in Kadaknath. The variations reported by different
studies can be due to the genetic backgrounds of the stocks
that varied in every single study.
Effect of genetic and non- genetic factors
Dalal et al. (2019) [4] reported that sire effect was highly
significant on BW20 but was non-significant on EP40 in
Aseel birds. They also reported non-significant effect of sire
on all the traits under study in case of Kadaknath birds. For a
successful execution of breeding program aimed at
improvement of population performance, the main pre
requisite is the proper and efficient selection of sire as sire is
considered as half of the flock. Contrary to the present
finding, Dalal et al. (2019) [4] reported highly significant
effect of hatch on BW20, BW40 and ASM.
Heritability (h2)
Kabir et al. (2006) estimated the heritability for BW20 and
BW40 of Aseel as 0.70 ± 0.35 and 0.42 ± 0.21 in the female
line. Dalal et al. (2019) [4] reported that the growth traits
showed moderate to high heritability (0.350.70) in Aseel and
low to medium (0.120.37) in Kadaknath.
Dalal et al. (2019) [4] found EP40 as medium heritable trait
viz. 0.35 in Aseel. The extreme variations in the heritability
estimates as per different reports might be attributed to the
differences in genetic background and variation in
environmental conditions.
Lower heritability estimate for ASM (0.19), EW40 (0.22) and
EP40 (0.14) in Kadaknath were reported by Dalal et al.
(2019) [4].
Genetic and phenotypic correlations
Contrary to present study, Dalal et al. (2019) [4] found that the
genetic correlation between BW40 and AFE was positive in
Kadaknath and negative in Aseel chicken. Negative genetic
correlation among AFE and EP40 was also reported. This
indicated that earlier the birds achieve sexual maturity, more
will be the number of eggs produced. Negative genetic
correlation between EP40 and EW40 are similar to the reports
of Sreenivas et al. (2012) [15] in white leghorn chicken and
Rahim et al. (2016) in Rhode Island Red chicken. Greater the
number of eggs, lesser will be the per egg weight. The
positive phenotypic correlation between BW20 and BW40
obtained in present study are in agreement with the findings
of Qadri et al. (2013) and Dalal et al. (2019) [4]. The genetic
and phenotypic correlations obtained in present study did not
reveal any specific trend in Aseel as well as in Kadaknath
native chicken birds which might be due to the fact that males
were not considered and the study was conducted only on
female birds. Also, not many reports are available to compare
the present estimates of heritabilities and genetic correlation
in Aseel and Kadaknath native chicken breeds.
Conclusion
Kadaknath and Aseel are the two most important native
chicken breeds of India. The present study concluded that
Aseel birds, being selected for fighting abilities showed
greater body weight gain compared to that of Kadaknath
birds. Both the breeds were observed to start egg laying
almost at similar age. However, Aseel breed was found to lay
more number of eggs up to forty weeks with higher egg
weight compared to that of Kadaknath. The study also
revealed that birds with lower body weight at twenty weeks
attain age at first egg late. Moderate to high heritability
estimates of various traits in Aseel and Kadaknath provide
scope for improvement in the flock using different means of
selection in future. High and positive genetic correlations
found among body weights and layer economic traits can be
exploited in developing models for genetic improvement in
production performance of native chicken breeds.

Aseel, an important Indian native chicken breed, characterized by its aggressive behaviour, fighting ability and majestic gait is being utilized in India for developing crosses for backyard poultry farming. Therefore, information regarding its growth models is a pre-requisite which is yet not available. So, present investigation is first of its kind in India which was carried out to evaluate various non-linear models and to find out the best fitting growth model in Aseel. Data on body weights from second week of age to 20 weeks of age at biweekly intervals were recorded on 1054 progenies from 30 sires and 139 dams hatched in three hatches and maintained at Desi Fowl Unit of Central Avian Research Institute, Izatnagar, Bareilly. Owing to the non-linear characteristic of growth, three non-linear models namely, Gompertz model, Bertalanffy model and Logistic model were evaluated. Goodness of fit for all the models were checked using coefficient of determination (R2 ), adjusted coefficient of determination (Adj-R2 ), Mean Square Error (MSE), Mean Absolute Error (MAE) and Akaike Information Criterion (AIC). The body weights at 0, 2, 4, 6, 8, 10, 12, 14, 16, 18 and 20 weeks of age averaged 28.18g, 65.94g, 138.99g, 237.06g, 359.95g, 533.74g, 718.28g, 922.33g, 1149.7g, 1321.65g and 1477.14g, respectively in males of Aseel native chicken. The corresponding body weights in females were 27.94g, 64.04g, 128.28g, 214.50g, 317.00g, 462.54g, 615.53g, 782.14g, 956.48g, 1077.65g and 1183.50g, respectively. Out of the three models, the Gompertz model, with R2 = 1.000, Adj�R2 = 1.000 and AIC = 29.839, best described the growth trend in males. In females, the Logistic model, with R2 = 0.999, Adj-R2 = 0.999 and AIC = 29.734 was found to be the best. In pooled or combined sex data, Gompertz model, having R2 = 0.999, Adj-R2 = 0.999 and AIC = 30.004, was determined as the best. The study revealed that these models can be used to determine the average body weights at any given point of time in Aseel native chicken under normal conditions. The investigation has generated baseline data on growth modelling and can also be used in other native chicken breeds.

This study aimed to assess the impact of non-genetic and genetic factors on growth and layer economic traits. Genetic and phenotypic parameters were also estimated for layer economic traits in Rhode Island Red (RIR) breeds. Records of chicken were collected from the Experimental Layer Farm of the Institute (CARI, Izatnagar). The estimated least square means for age at sexual maturity (ASM), Body weight at 20 and 40 week of age (BW20 & BW40), egg weight at 28 and 40 weeks of age (EW28 & EW40) and egg production at 40 week of age (EP40) were found as 186.37±1.67 days, 1517.69±0.40 g, 1783.43±0.73 g, 41.69±00.29g, 48.87±00.21 g and 51.06±1.33egg, respectively. Sire had a significant (P≤0.05) influence on ASM, BW20 and EW40 and hatch showed nonsignificant effect on all traits except EP40. The highest estimates were observed in 2nd hatch for all layer economic traits but the lowest estimates were for growth traits. Birds born in the first hatch were heavier than those of second hatch due to differences in nutrition, and management in the various hatches. Low heritability was estimated for EP40 and BW40 while ASM and BW20 were moderately heritable.

Aseel, a popular breed of native chicken, characterized by its pugnacity, fighting strength and royal gait, is being used to create crosses for domestic chicken production. However, information on its growth models is scanty. An experiment was conducted to evaluate different non-linear models and to find out best fitting model in Aseel, being maintained at Central Avian Research Institute, Izatnagar, Bareilly. Data on body weights from 12-weeks of age to 20-weeks of age at biweekly intervals were recorded on a random bred single hatched flock. Owing to the non-linear characteristic of growth, three non-linear models namely, Gompertz, Bertalanffy and Logistic models were evaluated. Goodness of fit for all the models were checked using coefficient of determination (R2), adjusted coefficient of determination (Adj-R2), mean square error (MSE), mean absolute error (MAE) and Akaike information criterion (AIC). The Bertalanffy model most accurately characterized the growth trend in males, females and pooled sex data. The study revealed that this model may be used to ascertain the average body weights in Aseel chicken under random mating. The investigation has generated baseline data on growth modelling of random bred groups and may be used in similar investigations on other native chicken breeds. Keywords: Aseel, Bertalanffy model, Gompertz model, Growth models, Logistic model.

of Hilly chicken under intensive rearing system at Chattogram district of Bangladesh. Livability, fertility and hatchability are the key features to poultry breeders. Because poor fertility and low hatchability incur loss in breeding operations and less livability significantly impact net returns. Therefore, higher fertility and hatchability and lower mortality of birds should be of direct interest to the poultry breeders. Hence the aim of this study was to estimate fertility, hatchability and livability up to first laying age of Aseel and F 1 of Hilly chicken. The Aseel and F 1 of Hilly chickens were collected from the Sarail Upazila of Brahmanbaria district and hill tract regions of Bangladesh. After collection, the chickens were kept in breeding flock as male and female ratio 1:1. The egg was stored in room temperature and hatched by the electric incubator. Fertility of Aseel and F 1 of Hilly chicks was found to be 95% and 75%, respectively. The hatchability of Aseel and F 1 of Hilly chicken based on fertile eggs was detected 94.74% and 86.67% but in case of total eggs the hatchability of the two genotypes was 90% and 65%, respectively. Livability of Aseel and F 1 of Hilly chicks up to first laying age was 88.89% and 46.15%, respectively. The first laying age of both Aseel and F 1 of Hilly were 210 and 180 days, respectively. Based on fertility, hatchability and livability, Aseel chicken was better than F 1 of Hilly chicken. So, the former breed is better for conservation issue than the later in the ex-situ conservation system.

Backyard poultry production plays a vital role in providing animal protein at affordable and sustainable manner. Growth and production potential of indigenous chicken need to be improved through selective breeding to enhance the productivity of backyard farming. PD-4 birds (Aseel, indigenous breed) were subjected to selection for higher body weight over eight generations. Study investigated effect of selection on the performance of PD-4 birds with respect to economic traits. There was significant improvement in body weight and shank length at 8 weeks of age. Egg production up to 40 weeks had improved by 19.1 eggs. Egg weight at 28, 32, 36 and 40 weeks of age improved by 0.8, 1.3, 1.7 and 1.3 g respectively. Age at sexual maturity had declined by 14.2 days. There was no significant change in fertility and hatchability traits. Survivors’ egg production up to 72 weeks of age was 156.5±2.79 eggs while hen day and hen housed egg production were 144.9 and 137.5 eggs respectively. Egg weight consistently improved from 35.13 g at age at first egg to 48.07 g at 40 weeks and to 49.63 g at 72 weeks of age. The study demonstrated that indigenous chickens could be improved for body weight and egg production without affecting other economic traits and improved PD-4 variety has the potential to be used as improved dual purpose indigenous chicken variety for low input backyard poultry farming. © 2019 Indian Council of Agricultural Research.

Aseel is an important native chicken breed of India, known for its martial qualities (aggressive fighting abilities), pugnacity, and majestic gait. The aim of the study is to conserve and characterize the Aseel germplasm, which is considered to be endangered. The birds were maintained on deep litter under a simulated backyard type of housing having night shelter and a free-range area. A total of 313 chicks produced in the second generation from the flock collected from native tract in Andhra Pradesh was characterized for morphological, growth, production, and meat quality parameters. Aseel birds were characterized by multicolored plumage (predominantly dark brown, black, golden, etc.) with solid feather patterns and normal distribution. Ear lobes were red (92%) and small in size, while 98% of the birds had red colored pea combs with variations in intensity of color. The shank color was yellow in the majority (65%) of the birds. The skin color was white (98%) with pinkish red coloration on exposed body parts, especially on the breast. The fertility and hatchability on total eggs were 67.2 and 41.4%, respectively. Cocks were heavier (P ≤ 0.05) with distinct sexual dimorphism in Aseel. The body weight of hens and cocks was 1,704.4 ± 23.2 and 2,702.5 ± 28.1 g at 40 wk and 2,333.7 ± 26.1 and 3,793.7 ± 20.8 g at 72 wk of age, respectively. The age at sexual maturity was 214.0 ± 6.0 days. The egg production up to 40, 52, and 64 wk of age was 18.0 ± 1, 30.0 ± 2.0, and 47 ± 3 eggs, respectively. The annual egg production (72 wk) was 64 ± 6 eggs. The proximate composition of breast muscle was; protein 21.5 ± 0.5%, fat 3.4 ± 0.1%, ash 2.0 ± 0.1%, and moisture 73.3 ± 0.5%. The pH of breast muscle was 6.0 ± 0.03 and the cholesterol content was 72.5 ± 6.7 mg/100 g. Efforts are on for improving the productivity in the flock without compromising the original breed characteristics.

The study aimed to evaluate kinetics of serum antibody response to Newcastle disease (ND) vaccine investigating 120 chicks from Aseel, Kadaknath and White Leghorn (WLH) maintained at this institute. The day-old chicks were vaccinated with a dose of 106.5 EID50 of live attenuated ND vaccine F1 strain through occulo-nasal route followed by a booster dose on 28th day. The antibody titre means were estimated and varied significantly among different dpi in Aseel, Kadaknath and WLH. The immune sera in Aseel and Kadaknath had gradual inclining antibody titre levels for longer dpi with the highest titre means at 42 dpi, whereas the sera in WLH had an irregular trend in antibody levels with the highest titre mean at 7 dpi. Aseel, Kadaknath and WLH also varied in mean antibody titres at 7, 14 and 42 dpi. The highest titre means at each 7 and 14 dpi were in WLH followed by Aseel and Kadaknath, respectively, whereas at 42 dpi was in Aseel followed by WLH and Kadaknath. The results indicated importance of the vaccination of day-old chicks against ND to enhance maternal derived antibody response and also speak about much better antibody response to NDV in Aseel and Kadaknath native fowl.

Aim: The present study was undertaken to estimate the genetic parameters and to assess the inheritance pattern of egg quality traits in White Leghorns. Materials and Methods: Data on 480 eggs produced by 40 week old pullets of 4 genetic groups were used for studying egg quality traits. Heritabilities and correlations were estimated by full sib correlation method using Mixed Model Least Squares and Maximum Likelihood (LSMLMW) computer program. Results: The egg weight, haugh unit, yolk index, albumen index, yolk weight, albumen weight, shell weight and shell thickness ranged from 50.01 ± 0.48 to 53.89 ± 0.43 g, 65.38 ± 0.92 to 80.98 ± 1.01, 0.341 ± 0.003 to 0.353 ± 0.003, 0.056 ± 0.002 to 0.087 ± 0.002, 14.16 ± 0.13 to 15.58 ± 0.12 g, 30.92 ± 0.39 to 33.18 ± 0.39 g, 4.32 ± 0.05 to 5.12 ± 0.05 g and 0.336 ± 0.003 to 0.376 ± 0.003 mm, respectively. Heritability estimates for egg weight, yolk index, albumen index and albumen weight ranged from low to medium while those of haugh unit, yolk weight, shell weight and shell thickness ranged from low to high. The genetic and phenotypic correlations of egg weight with other egg quality traits except shell quality traits were mostly positive and moderate to high. High positive genetic and phenotypic correlations between haugh unit and other traits were observed. Genetic correlation of yolk weight with albumen weight was positive while that with shell quality traits was mostly negative. Shell weight was positively correlated with shell thickness. Conclusion: Significant genetic group differences were observed for various egg quality traits studied. The heritability estimates for different egg quality traits were low to moderate. The association among egg quality traits was positive in general.

The experiment was conducted to study the egg production potential and persistency of egg production up to 44 weeks of age, egg weight, egg mass, biochemical parameters and egg quality traits in Aseel and Kadaknath breeds. Higher persistency of production was observed at 40 weeks of age in Aseel (50.81%) and at 44 weeks of age in Kadaknath (54.35%). Persistency of production in Aseel was relatively higher during initial stage of production (28–36 weeks) while it was higher in Kadaknath during later stage (40–44 weeks). Over all, higher 44 weeks egg production was observed in Kadaknath than in Aseel. Egg weight was significantly higher in Aseel as compared to Kadaknath. Egg mass recorded from 28 to 40 weeks of age was also higher in Aseel than in Kadaknath. Serum cholesterol levels at 20 and 32 weeks of age were significantly higher in Kadaknath as compared to Aseel while serum protein level (20 weeks) was significantly higher in Kadaknath. No significant difference was observed in antibody (HI) titre to New Castle disease virus between these breeds. Cage house survivability was similar in Aseel (97.53%) and Kadaknath (97.17%). Egg quality study revealed that yolk, albumen and shell weights were significantly higher in Aseel than Kadakanth, while shell percentage was significantly higher in Kadaknath. The study concluded that the persistency and number of egg production up to 44 weeks of age was relatively better in Kadaknath as compared to Aseel.

The present study was conducted to assess and compare the performance of Aseel and Kadaknath chicken in addition to the estimation of genetic and phenotypic parameters of growth, production and reproduction traits in both indigenous breeds. Single-generation data (2018) were collected from the records maintained at Poultry Breeding Farm, Department of Animal Genetics and Breeding, LUVAS, Hisar. The least-squares means for different growth, reproduction and production traits, viz., body weights at 8 (BW8), 12 (BW12), 16 (BW16), 20 (BW20) and 40 (BW40) weeks of age, age at first egg (AFE), egg production up to 40 weeks of age (EP40) and egg weight at 40 weeks of age (EW40), were 461.41 ± 10.09 g, 683.64 ± 15.10 g, 886.01 ± 20.24 g, 1117.30 ± 22.68 g, 1772.02 ± 18.86 g, 182.66 ± 1.98 days, 64.89 ± 2.10 and 47.23 ± 0.42 g in Aseel breed. The corresponding figures in Kadaknath breed were 343.63 ± 5.67 g, 552.35 ± 6.97 g, 719.04 ± 9.02 g, 920.47 ± 11.20 g, 1581.13 ± 13.37 g, 169.83 ± 0.95 days, 55.48 ± 1.22 and 41.99 ± 0.29 g, respectively. Higher body weights were observed for Aseel breed compared to Kadaknath breed at different ages. The effect of the hatch was significant for all the growth traits and AFE in Kadaknath chicken, while it was significant only for BW12 in Aseel chicken. Genetic correlations among body weights at different ages and AFE in both the breeds were found to be negative, indicating that lower body weights of birds within a breed lead to delay in AFE. Heritability estimates for different performance traits ranged from moderate to high (0.26–0.70) in Aseel and low to moderate (0.12–0.37) in Kadaknath chicken, suggesting the scope of improvement through individual and family selection in both the indigenous breeds.

In present investigation, 325 single-hatched RIR chicks that has undergone 30 generation of selection based on 40-week part-period egg production were evaluated for growth and layer economic traits using least-squares analysis of variance. Overall least-square means of body weight at 16, 20, 40 and 64 weeks of age were 1362.6±21.4g, 1791.6±24.5g, 2184.6±26.2g and 2433.8±34.2g, respectively. Males were significantly heavier than females (P£0.001) at all ages. Least-square means of age at sexual maturity, egg weight at 28, 40 and 64 weeks of age, egg number up to 40 and 64 weeks of age were 134.5±0.9days, 44.8±0.3g, 47.73±0.4g, 51.5±0.7g, 118.3±1.2eggs and 214.5±4.8eggs, respectively. Heritability estimates were high for growth and low to medium for layer economic traits. Genetic and phenotypic correlations among body weights were high and positive. The egg production up to 40 weeks revealed high and positive genetic (0.89±0.15) as well as phenotypic (0.63) correlations with egg production up to 64 weeks suggesting the its usefulness as selection criterion for genetic improvement of annual egg production.
