This study aimed to evaluate the performance, some carcass characteristics from feedlot lambs receiving sunflower crushed (SC) in the diet on partial replacement of soybean meal. The experimental design was randomized block with four levels of SC in the diet (0, 10, 20 and 30% of dry matter (DM)). There was a linear reduction of 0.02; 0.003; 0.003 and 0.17% for each percentage unit of added SC ...

Accuracy and repeatability of live-animal ultrasound measures, and the relationships of these measures with subprimal yields and carcass value, were investigated using data from 172 wethers. Wethers were F(1) progeny from the mating of 4 terminal sire breeds to Rambouillet ewes and were finished in a feedlot to a mean BW of 62.9 kg (SD = 9.5 kg). Before transport to slaughter, LM area, LM depth...

UNLABELLED A study was conducted to establish the response of Pekin ducks to dietary Met from 15 to 35 d age. Experimental diets were formulated to contain 0.35, 0.45, 0.55, 0.65, and 0.75% Met (0.30, 0.39, 0.45, 0.56, and 0.68% on an analyzed basis, respectively) and 0.3% cysteine (0.25, 0.27, 0.26, 0.26, and 0.28% on an analyzed basis, respectively). Each diet was fed to 10 pens of 55 ducks/p...

A two-year experiment evaluated the effects of sorting long yearling steers by initial feedlot BW and supplementing 200 mg/steer of Optaflexx daily the last 28 days of the feeding period on ADG, F/G, carcass characteristics and profitability. Feedlot ADG, F/G, and profitability were not effected by sorting. However, sorted cattle exhibited increased fat thickness, increased rib-eye area, and in...

Cut-out data from 2,550 steer carcasses representing British, Continental and Zebu breeding were analyzed to evaluate yield grade classes based on three equations: 1) Ya = 2.5 + .984 AFT + .0084 HCW - .05 REA + .2 KPF; 2) Yb = same as Ya with intercept changed to 3.2 and KPF deleted; 3) Yc = 3.0 + .984 AFT + .0041 HCW - .03 REA, as proposed by USDA in 1984; where AFT = adjusted fat thickness (c...

Study was carried out to find out the effect of L-carnitine supplementation on carcass characteristics in Venncobb broiler chicks fed with diet containing animal fat. Eighty day old commercial broiler chicks were randomly allotted to two treatment groups (T1 and T2) with four replicates of ten chicks each. The birds were fed with standard broiler chicken ration (BIS, 1992) containing 5% animal ...

A study was carried out to find the effect of feeding Cow urine ark and Aloe vera extract on performance and carcass traits of broilers. For Performance Quality, Body Weight of birds were weighed on weekly basis till 6 weeks of age. Weight gain in different groups of broilers was calculated on weekly basis. Evaluation of Feed Intake was done on the basis of feed offered and left over feed recor...

The most valuable lean cuts from Iberian pigs are the hams, forelegs, and loins, which yield high quality cured meat products. This study aimed to assess the correlation between body composition measurements taken in vivo by ultrasonography in Iberian pigs and those taken on the carcass, which were then used to develop predictive models to estimate the weight and yield of these cuts. Before sla...
