Feedlot performance and carcass traits were compared between Charolais and Brahman sired three-breed cross calves. Data were obtained on 251 calves (127 heifers and 124 steers). All calves were placed on a self-fed finishing ration immediately after wea,ning and slaughtered when each animal attained an estimated low choice carcass grade. Feedlot performance favored calves sired by Charolais. Ch...

Live measurements of weight, height, length, girth, fat depth, stifleand hip-width were obtained prior to slaughter to develop prediction equations for carcass traits. The animals were boned out after slaughter and comprised 182 steers from the Southern Crossbreeding Program (progeny from Hereford cows crossed with seven sire breeds: Angus, Belgian Blue, Hereford, Jersey, Limousin, South Devon ...

A study was conducted to find out the differences in carcass traits among the Cobb-400, Vanraja, Aseel and Kadaknath Breeds of chicken. Cobb-400 showed significantly (P<0.05) higher live weight and dressing percentage than indigenous breeds (Vanrja, Aseel and Kadaknath) at the age of six week. Hot carcass weight as well as cold carcass weight were significantly (P<0.05) higher in comparison to ...

Mass selection for an index of increased postweaning average daily gain and decreased backfat thickness was practiced for five generations. Litter size and weight for 221 gilt litters, birth weight and nipple number for 2,242 piglets and weaning weight at 42 d of age for 2,111 pigs were recorded. Carcass measurements were taken on 331 pigs. Differences between means of the lines (select control...

Approximately 4,000 yearling heifers (initial BW = 306 ± 1.9 kg) were randomly allotted into 4 treatment groups to determine the effect of melengestrol acetate (MGA) on feedlot performance and carcass parameters. Treatments included a diet containing monensin (Rumensin) and tylosin (Tylan; RT) fed during the entire feeding period; RT plus MGA (RTM) also fed during the entire feeding period; RT ...

Carcass data from more than 4,400 Southdown x Romney ewe and wether lambs collected over a 16-yr period were analyzed for the effects of sex, rearing status, and growth rate. Ewe lambs grew more slowly than wethers and had .78 kg less carcass weight at the same age. The carcass weight advantage for wethers was nearly all caused by heavier fat-free weight. Based on fat depths, the fat on ewe lam...

Influence of Dietary Supplementation with Organic and Inorganic Selenium Sources on Growth Performance, Carcass Traits Blood Metabolites in Geese Chicken

Improving carcass composition is one factor that can have an impact on lamb consumption and demand (Ward, 1995; Purcell, 1998). Increased size of cuts and decreased fatness are two factors that affect consumer acceptability of lamb (Jeremiah et al., 1993). The lamb producer that markets superior carcasses, with greater consumer appeal, expects to realize financial rewards from doing so. The exp...

Carcass quality of JamunaparixBlack Bengal (JBB), Black Bengal selected for growth (SBB) and random-bred (RBB) wethers of 1 year of age was studied. There was no significant difference between JBB and SBB in pre-slaughter traits and carcass characteristics, except height at wither and dressing percentage which were significantly higher in JBB than in SBB, and muscle fiber diameter which was sig...
