An experiment was conducted to determine growth and carcass characteristics of male broilers subjected to early feed restriction. Restricted birds were fed equivalent to 1/5*BW0.67 Kcal/day/bird between days 7 and 14. On days 0 to 7 and 14 to 56, all chickens received feed ad-libitum. Diets of feed-restricted birds were supplemented with 15% higher methionin and cystine recommended by NRC (1994...
Progressive growth of the Walker 256 carcinoma produces anorexia and loss of carcass weight (6). Carcass weight loss has been prevented by forcefeeding a high fat diet, but other systemic effects (decreased liver catalase activity, anemia, and adrenal enlargement) still occurred (1). It was suggested that loss of carcass weight is not a neces sary component of the reactions leading to the devel...
The objective of this study was to identify quantitative trait loci for economically important traits in two families segregating an inactive copy of the myostatin gene. Two half-sib families were developed from a Belgian Blue x MARC III (n = 246) and a Piedmontese x Angus (n = 209) sire. Traits analyzed were birth, weaning, and yearling weight (kg); preweaning average daily gain (kg/d); postwe...
Carcass and price traits of 72,969 Hanwoo cows, bulls and steers aged 16 to 80 months at slaughter collected from 2002 to 2013 at 75 beef packing plants in Korea were analyzed to determine heritability, correlation and breeding value using the Multi-Trait restricted maximum likelihood (REML) animal model procedure. The traits included carcass measurements, scores and grades at 24 h postmortem a...
In order to investigate the effect of phytase and copper supplementaion on growth and carcass composition of common carp (Cyprinus carpio L.), in a completely randomized design with 3 ×2 factorial arrangement with three replicates the experimental diets including three levels of phytase 0, 500 and 1000 (FYT) kg-1 and two levels of copper 0 and 15 mg/kg were tested. Diets contained 0.72 percent ...
an experiment was conducted under completely randomized design to investigate effect of various levels of terbutalin, a bete-adrenergic agonist, by procuring 120, 35-d age male cobb broiler chicks from d 29-49. the birds were randomely distributed into 3 treatments and 4 replicates with10 birds each. the birds were fed experimental diets with different levels of terbutaline at levels 0.0 (contr...
In beef cattle farming, growth and carcass traits are important for genetic breeding programs. Molecular markers can be used to assist selection and increase genetic gain. The ADIPOQ, OLR1 and PPARGC1A genes are involved in lipid synthesis and fat accumulation in adipose tissue. The objective of this study was to identify polymorphisms in these genes and to assess the association with growth an...
A total of 144 male crossbred calves were allocated to four management treatments (bulls; steers; bulls implanted with zeranol at 100 d of age and re-implanted at 69, 93 and 56 d thereafter; bulls implanted with zeranol at 168 d of age and re-implanted at 93 and 56 d thereafter), and two pre-slaughter shipping treatments (minimum pre-slaughter stress with cattle shipped and slaughtered within 4...
This experiment was carried out to determine the relationship of plasma triglycerides and carcass dry matter with abdominal fat. One of the problems of broiler is carcass fatness, especially abdominal fat due to rapid growth of broilers which is not the consumer preference. Six hundred one-day-old commercial broiler chicks (Lohman) were divided into 40 groups, 15 chicks per group. Each one of t...
