Live animal and carcass data were collected from market barrows and gilts (n = 119) to determine the accuracy and precision of using a single longitudinal scan, parallel to midline, in estimating body and carcass composition. Data from test pigs (n = 96) were used to develop prediction equations. Best results were obtained in predicting weight of boneless cuts (ham, loin, and shoulder), weight ...

Beef steers (n = 11,877) from 7 studies were fed zilpaterol hydrochloride (ZH) for 0 or 20 to 40 d before slaughter to determine the effects of ZH on subprimal weight and yield. Carcasses were selected based on mean HCW of treatment groups for fabrication into boneless, closely trimmed, or denuded subprimals, lean, fat, and bone. Data from the 7 trials were pooled for statistical analysis. Feed...

The aim of the study was to compare effects feed restriction on growth performance and carcass composition chicken, rabbit nutria males females. Feed applied at a rate 70% ad libitum from 14 21 days age in chickens, 42 49 rabbits, 12 15 weeks nutrias. Animals were fed prior following restriction. Carcass evaluated common slaughter ages, i.e., 31 70 eight months results showed stronger restricti...

Correlated effects of selection for components of litter size on carcass and meat quality traits were estimated using data from 3 lines of pigs derived from the same Large White base population. Two lines were selected for 6 generations on high ovulation rate at puberty (OR) or high prenatal survival corrected for ovulation rate in the first 2 parities (PS). The third line was an unselected con...

This study aimed to compare the growth performances and carcass characteristics of tropical-breed steers reared in 2 contrasted feeding systems (indoor vs. pasture) and slaughtered at different ages (early vs. late). A total of 309 Creole steers (growing at an initial BW of 173 ± 3 kg and an initial age of 252 ± 4 d) were used over a continuous 12-yr study. Indoor steers were housed in a cattle...

The effect of dietary Terbutaline, a beta adrenergic agonist, on carcass characteristics and blood attributes in 288 Japanese quails was studied from 21 through 49 days of age. Dietary treatments included four levels of Terbutaline [0 (T0), 1 (T1), 3 (T3), and 5 (T5) mg/Kg of the diet]. Quails were bled at the end of the trial for biochemical assays and the carcass characteristics were then mea...

this experiment was conducted to evaluate the effects of different commercial multi enzymes and nutrients levels of diets on performance and carcass traits of broilers. in this experiment 288 day old ross – 308 broilers (male and female) were used as (2*4) factors include: two levels of nutrients in diets (ross- 308 nutrients recommendation and 5% less than ross- 308 nutrients recommendation) a...

The purpose of this study was to investigate the closed-house cage density near outlet that affected production carcass, non-carcass, and abdominal fat finisher phase broilers ascertain number could produce ideal amount low fat. experiment employed a completely randomized design with four treatments: T0 (10 birds per square meter), T1 (12 T2 (14 T3 (16 meter). It replicated five times using dif...

Rusa deer are the only viable commercial tropical deer species for farming in the tropics because of their hardiness, adaptability and prolific characteristics. Twelve entire rusa stags were slaughtered according to halal procedure and used for carcass evaluation and cutability studies. Three carcass categories; large (46 to 55 kg), medium (36 to 45 kg) and small (25 to 35 kg) were developed fo...
