Two experiments were conducted to examine the effect of previous BW gain during winter grazing on subsequent growth, carcass characteristics, and change in body composition during the feedlot finishing phase. In each experiment, 48 fall-weaned Angus x Angus-Hereford steer calves were assigned randomly to one of three treatments: 1) high rate of BW gain grazing winter wheat (HGW), 2) low rate of...

An experiment was conducted to assess the effect of dietary supplementation of garlic (Allium sativum) and fenugreek (Trigonella foenum-graecum L.) seed powder as herbal feed additives on growth performance, carcass characteristics and economics of feeding in broilers. A total of 320 day old broiler chicks of Cobb-400 strain were divided into four treatment groups with 4 replicates of 20 chicks...

The growth performance and the carcass and physical and chemical characteristics of the meat of 24 Landrace X Large White pigs were compared when reared under a free-range or a conventional housing system. The free-range pigs had lower feed intakes and slower growth rates than the conventionally housed pigs. The free-range pigs also had a lower P2 fat depth and therefore yielded a carcass with ...

(Co)variance component estimates were computed for retail cuts per day of age (kilograms per day), cutability (percentage of carcass weight), and marbling score (1 through 11) using a multiple-trait sire model. Restricted maximum likelihood estimates of (co)variance components were obtained via an expectation-maximization algorithm. Carcass data consisted of 8,265 progeny records collected by U...

ABSTRACT: Two experiments were conducted to evaluate the effects of feeding continuously a diet containing 40% dried distillers grains with solubles (DDGS) or intermittently diets containing 20 or 40% DDGS on growth performance and carcass quality of pigs. Responses of the pigs to abrupt introduction and removal of dietary DDGS with differing concentrations of standardized ileal digestible (SID...

Twenty crossbred steers (400±40.1 kg of initial body weight) were used to assess the effects of a dietary supplementation with crude glycerin (CG) as a substitute for corn grain on performance, carcass traits, and meat quality. Four isocaloric and isonitrogenous diets were offered to the experimental animals (5 steers per treatment) for 121 days using randomized complete block design. The steer...

an experiment was conducted to evaluate the effects of biogen probiotic additives on growth performance of common carp, cyprinus carpio. four practical diets containing 0 (control) , 0.1, 0.2 and 0.3 % biogen probiotic were used to feed fish. seventy-two juvenile common carp (65 ? 3.5g) were randomly distributed between 12 fiberglass tanks of 500 l capacity. during 60 days of feeding trial, the...
