Article
Efficient conversion of food into body mass has been associated with altered gene expression of some proteins of the electron transport chain. We evaluated the effect of age on the mRNA expression of Cytochrome oxidase III(COX III), avian adenine nucleotide translocator (avANT), avian PPAR-γ coactivator-1α (avPGC-1α), Peroxisome proliferator-activa...

Meat byproducts are rendered for use in livestock and poultry diets to reduce the feed cost (Caires et.al. 2010). The most common animal by products used in broiler chicken diets are meat meal and bone meal, blood meal, feather meal and poultry offal meal. These byproducts contain high protein and may partially replace other protein rich feed sourc...

Chicken is a nutritious, healthy food which is low in fat and cholesterol compared to other meats but an excellent source of protein. Meat must be of a high microbiological quality in order to ensure that the consumer receives a product that is not spoilt or does not carry food-borne disease. Food borne diseases associated with the consumption of p...
Article
An experiment was carried out to evaluate nutritional interventions to minimize nitrogen excretion in broilers. Three dietary treatments with 42 birds each were subjected to standard protein diet (T1), low protein with balanced amino acids (T2) and low protein with balanced amino acids plus enzyme (T3). Production performance (body weight, feed eff...
Article
Biological experiment was conducted to fi nd out the effect of exogenous cellulase at three different levels of 112.5 CMC u/Kg, 225 CMC u/Kg and 450 BG CMC u/Kg of feed along with control in Turkey pre brooder and brooder rations. Eighty straight run Beltsville Small White Turkey poults were randomly allotted to different treatment groups with two...
Article
A 24 weeks experiment was conducted to evaluate the effect of strain, age and sex on the growth performance and feed conversions of three strains of Turkeys namely Beltsville small white (BSW), Desi and Nandanam Turkey I (NTI) (a strain developed by Tamilnadu Veterinary and Animal Sciences University, Chennai, India). The experimental design was a...
Article
Foods or food ingredients that provide a health benefit beyond normal nutritional effects through modulation of specific target functions are generally known as functional foods. All foods are functional to some extent as they provide taste, aroma, nutrients required for normal metabolism, growth and maintenance. However, foods are now being examin...

Ostriches are being reared in India from 2000 onwards. The data on reproductive performance recorded over a period of seven years (2002 - 2008) were analysed. Ostriches revealed sexual dimorphism at an age of around 270 days and the mean age of sexual maturity observed was 787.8 ± 29.9 days. The average annual egg production over seven years of stu...

A biological trial was conducted on straight run day-old Beltsville small white turkey poults (40, which were randomly distributed into 2 treatments having 2 replicates/treatment and 10 poults/replicate. High fibre (8.91%), low energy (2606 K cal/kg of metabolizable energy) experimental diet having crude protein content of 25.91%, and with or witho...

The present study was carried out in turkey birds maintained at Institute of Poultry Production and Management, TANUVAS, Chennai, spread over 3 years (2009-2010 to 2011-2012). Causative agents were listed and per cent mortality was calculated during different seasons. There are four seasons, viz. winter, summer, southwest monsoon and northeast mons...
Article
The study concluded that two and four per cent inclusion levels of ossein in the layer feed resulted in better part time egg production performance and economics in White Leghorn layers. However, a trend of reduction in egg weight was observed by the inclusion of ossein.

Confectionery may require reclamation or reworking for a number of reasons; when high speed production lines stop because of a problem downstream, such as a fault in coating machines or a breakdown in the packing line. Equally, sweets may be rejected as being misshapen. Ingredients produced on a continuous basis were often diverted into scrap bins...

The results of the present study revealed significant differences in Haemoglobin, Packed Cell Volume, and RBC among different species of poultry. The mean value for PCV were significantly (P ≤0.01) highest in Japanese quail (36.83) followed by guinea fowl (33.16) geese (32.00) and least in turkeys (30.66). In chicken the highest values were recorde...
