    ABSTRACT: In recent years, there has been an increase in the use of organic acids as substitutes for antibiotic growth promoters because of the fear of antibiotic resistance and the implications for human health. Organic acids and their salts have been used in poultry diets and drinking water for decades and seem to elicit a positive response in growth performance. An important objective of dietary acidification is the inhibition of intestinal bacteria competing with the host for available nutrients, and a reduction of possible toxic bacterial metabolites resulting in the improvement of nutrient digestibility, thereby ameliorating the performance of birds and enhancing the specific and non-specific immunity in poultry. Literature shows that short-chain fatty acids, medium-chain fatty acids and other organic acids have more or less pronounced antimicrobial activity, depending on both the concentration of the acid and the bacterial species that is exposed to the acid. The possible mechanisms contributing to these effects and the factors thought to explain the variability in these responses are discussed. This paper provides a review of the use of organic acids in the prevention of enteric disease in poultry, the effect on the gastrointestinal tract, nutrient digestibility, immunity and performance of broiler and laying hens.

    ABSTRACT: In this study, we investigated the polymorphisms of Caprine osteopontin (OPN) gene and their association with placental traits and prolificacy in goats. The placental and reproductive traits of 171 litters on three goat breeds with different prolificacy (Dazu Black, n = 94; Lezhi Black, n = 27; Hexi Cashmere, n = 50) were evaluated. The polymorphisms in the 5′ promoter and exon 7 of OPN gene were detected by PCR-SSCP methods. Their association was further achieved by using least squares means. It showed that the litter size, litter and placenta weight for Dazu Black and Lezhi Black goats were higher significantly than those of Hexi Cashmere goats (P < 0.01). However, the placental efficiency was not significantly different (P > 0.05). Hexi Cashmere does have more cotyledons in placental than that of Dazu Black and Lezhi Black does (P < 0.01). There were only two genotypes (nominated AA and AB) detected whether by the 5′ promoter primer pairs or by exon 7 of OPN gene. They were associated with litter number, with a trend of AA > AB. At the exon 7 locus, the Dazu Black does with genotype AA had 0.88 more litter numbers than those with genotype AB (P < 0.05). It suggested that OPN gene could be a potential candidate gene on goat prolificacy.

    ABSTRACT: In this study the possibility of body size estimation of new born lambs using image processing and its effect on the genetic gain of a simulated population has been investigated. The body size of 158 new born lambs of Zandi sheep was evaluated via appraisal method, digital image processing and metric methods. The correlation coefficients between metric lamb size with quantities were calculated from image processing method and appraisal method were 0.88 and 0.48, respectively (P < 0.01). In the next step, two populations were randomly simulated using R2.15 programming environment, and two different scenarios based on two lamb size measurement methods were studied. In the first scenario, it was assumed that the animal body size is determined using image processing technique in continuous values, while in the second scenario it was assumed that the body size is determined via appraisal method in discrete values. As results, the accuracies of breeding value estimations in the first and second scenario were 0.89 and 0.78, and the genetic trends were 0.46 and 0.28, respectively (P < 0.01). The results showed that determination of lamb size based on proposed image processing method is feasible, and replacement of this new method instead of human appraisal method could increase the genetic gain in the breeding herds.

    ABSTRACT: Schistosoma spindale and Schistosoma indicum are the most prevalent causes of visceral schistosomosis among bovines of India. The infection causes morbidity, mortality, reduced productivity and poor subsequent reproductive performance and it is economically significant in producing animals. The high prevalence of S. spindale among slaughtered bovines of South India warrants the need to devise improved diagnostics for specific and timely detection of infection for appropriate treatment and control. The present study focused on analysing the excretory-secretory proteins of S. spindale and identification of the immunodominant polypeptide fractions of this antigen. The major polypeptide antigens corresponding to approximately 28 and 66 kDa size could be detected as highly immunogenic during natural infections in cattle. Consistent blotting pattern was observed with known schistosome positive bovine sera and specificity of the antigen was also ascertained with sera of amphistome and strongyle positive animals.

    ABSTRACT: The aim of the current experiment was to determine the effect of species on chemical composition metabolisable energy (ME), organic matter digestibility (OMD) and methane production of oak nuts. The crude protein content was ranged from 2.71% to 6.14%. Crude protein of oak nuts from Quercus ithaburensis ssp. macrolepis was significantly higher than those of the other oak species. Neutral detergent fibre (NDF) and acid detergent fibre (ADF) contents of oak nuts were ranged from 19.29% to 34.58% and 12.65% to 20.85%, respectively. NDF and ADF contents of oak nuts from Quercus coccifera were significantly higher than those of the other oak species. The NFC contents of Quercus suber and Q. ithaburensis ssp. macrolepis were significantly higher than those of Q. coccifera and Quercus branti. Condensed tannin contents of oak nuts were ranged from 1.48% to 3.50%. Condensed tannin contents of oak nuts from Q. coccifera and Q. branti were significantly higher than those of Q. suber and Q. ithaburensis ssp. macrolepis. As conclusion, species had a significant effect on the chemical composition ME, OMD and methane production of oak nuts. Oak from Q. ithaburensis ssp. macrolepis will provide nut with quite digestible and high ME for ruminant animals although it is likely that animal consumed oak nut from Q. ithaburensis ssp. macrolepis will produce more methane and more pollutant to environment. However further investigations are required to determine the effect of oak species on the feed intake and animal performance.

    ABSTRACT: The purpose of this study was to evaluate the effects of three seaweeds Kappaphycus alvarezii (KA), Eucheuma denticulatum (ED) and Sargassum polycystum (SP) meal as dietary ingredients in the diets of Asian seabass juvenile on growth performance, feed utilization efficiency and body composition of Asian seabass, Lates calcarifer juveniles. A total of four experimental diets were formulated with 5% inclusion of KA, ED and SP. A diet without inclusion of any seaweed was used as a control diet. Experimental diets were fed to triplicate group of 20 Asian seabass juveniles with initial body weight of 9.73 g ± 0.60 g in an 8-week feeding trial. Growth performance and feed conversion ratio were not significantly affected by the seaweed inclusion in the fish diet; however, the total feed intake was significantly improved (P < 0.05) in fish fed with SP-Diet. Fish carcass composition varied among treatments, with fish fed with control diet demonstrated significantly higher protein and lipid contents. Whereas, fish fed with SP-Diet exhibited significantly higher ash content compared to other dietary treatments. KA-Diet proved that it was the most stable feed among all dietary treatments. On the other hand, the stability of SP-Diet was comparable to the Control-Diet. This indicates that the tested seaweed is able to replace commercial feed binder in the diet formulation. Considering the good performance of K. alvarezii, E. denticulatum and S. polycystum in the present study and the local availability of the seaweed, they can be considered as potential ingredients in the diets for Asian seabass juveniles.

    ABSTRACT: Most of the available scientific literature concerning claw vacuum drops and fluctuations (identical to teat-end vacuum) during machine milking has been published in the 1960s and 1970s. Fewer studies have been carried out more recently on modern types of dairy cows, and milking machines, and have been evaluated with modern statistical methods and software. Based on the accessible information, there are indications that reduced milking performance, leading to long machine-on time mainly as a consequence of a combination of vacuum drops and different types of fluctuations, may influence udder health in a negative way although scientific proofs are scarce. Based on an ISO note, the claw vacuum should remain within a range of 32-42 kPa during peak milk flow to ensure fast, complete and gentle milking. This range of vacuum pressure allows adequate liner movement and a sufficient pressure on the teat during the massage (d-) phase is guaranteed. Thus, liner slips caused by too low claw vacuum are avoided. On the other hand, the teat-end vacuum should not be much higher than 42 kPa as it can cause damage of teat tissue mainly during periods of low milk flow when it is almost identical with the system vacuum. Depending on the used system of milk transport through the tubes, the teat-end vacuum drops to some extent, intensified during periods of high milk flow and reduced during periods of low or absent milk flow at the start and end of milking. Hence, a general increase of system vacuum throughout milking is not suitable, as high teat-end vacuum acting on the teat during milking phases with low milk flow rates have to be avoided. However, a reduction of machine-on time and high vacuum load on the teat during low milk flow can potentially be achieved by early cluster removal, before complete cessation of milk flow. Ideally, this goal can be reached at quarter milking (as used in automatic milking systems) where each teatcup is individually removed based on the milk flow of the individual teat, and milking at very low or no milk flow can easily be avoided.

    ABSTRACT: An experiment was conducted to examine the effects on mortality, production performance, water intake (WI) and organ weight of Satureja khuzistanica essential oil (SkEO) using 720 one-day-old Arian broiler chicks in a 42-day trial. Experimental treatments were addition of 0 (control−), 200, 300, 400 and 500 mg/L SkEO or 500 mg/L polysorbate-80 (control+) into drinking water. The birds were kept under natural ambient temperatures 4-6°C above standard recommendation from days 22 to 42 of age. Addition of SkEO into drinking water at 200 and 500 mg/L decreased weight gain (P < 0.05) of the birds from days 29 to 35 of age with no differences in feed intake (FI) and feed conversion ratio (FCR) compared to control groups (P > 0.05). Addition of 300 and 500 mg/L SkEO into water increased mortality rate of the birds mainly from days 29 to 42 of age. The calculated European broiler index was greater for the birds receiving drinking water supplemented with 400 mg/L of SkEO compared with the other birds. In conclusion, administration of SkEO at 400 mg/L through drinking water to heat stressed broiler chickens may result in improved production performance efficiency.

    ABSTRACT: Effects of preslaughter immunological stress induced by lipopolysaccharide (LPS) on antioxidant performance and meat quality of broilers were investigated. Twenty-four broiler chickens (39 days old) with near-mean body weight (BW) were randomly divided into three following treatments: sham injection of saline (control), daily subcutaneous (s.c.) injection of LPS (3 mg/kg or 6 mg/kg of BW, respectively.) for three days. The results showed that average daily feed intake and daily gain of chickens were significantly decreased in the LPS treatment (P < 0.05). The F/G was significantly enhanced (P < 0.01). The LPS treatment had no significant influence on carcass performance (P > 0.05). The LPS treatment significantly decreased the pH at 24 h postmortem in breast muscle (P < 0.05) and significantly increased the water-holding capacity (WHC) of breast muscle (P < 0.01). It was the same as the change of yellowness (b*) at day 3 postmortem and lightness (L*) at day 6 postmortem in breast muscle (P < 0.05), but had no significant influence on shear force of breast muscle (P > 0.05). The pH at 45 min or 24 h postmortem of thigh muscle was significantly dropped in the LPS treatment (P < 0.01), however, the WHC and shear force of thigh muscle were not significantly different (P > 0.05). The yellowness (b*) significantly increased at day 3 postmortem of thigh muscle (P < 0.05). The plasma, breast muscle and thigh muscle MDA were significantly enhanced in the LPS treatment (P < 0.05). The total antioxidant capacity (T-AOC) level was significantly suppressed (P < 0.05); however, the plasma activity of glutathione peroxidase (GSH-Px) was slightly decreased (P > 0.05). The results of present study suggested that LPS-induced preslaughter immunological stress could increase body oxidative damage and decrease oxidation resistance, resulting in a decrease in growth performance and meat quality of broilers; also these adverse effects could be rested with the stress intensity.
