Mature cows (146) representing Angus, Braunvieh, Charolais, Gelbvieh, Hereford, Limousin, Pinzgauer, Red Poll, and Simmental breeds were slaughtered to contribute to the investigation of the effect of various feed availabilities on body composition. Weights recorded when cows were placed on feed were used to set daily diets at four rates of intake within each breed (55, 76, 96, and 111 g DM/[kg...

effects of partial docking on feedlot performance and body fat characteristics were studied in a fat-tailed sheep breed. thirty-eight male lambs with an average weight of 4.44 ± 0.48 were randomly divided into two groups. the lambs in one group were partially docked at 3-4 h after birth, using rubber rings, and the lambs in another group remained intact (control). after weaning, 20 male lambs f...

The objective was to evaluate different levels of crambe cake (CC) protein (0, 250, 500, 750 and 1000 g/kg DM) as a replacement for soybean meal in diets lambs their effect on performance, carcass traits meat quality. Forty not castrated crossbred male lambs, weighing 20 ± 3.45 kg, were settled completely randomized design with eight replicates per treatment. Final body weight (BW), dry matter ...

A six-week trial was conducted to study the effect of decreasing dietary crude protein (CP) level on the performance of broilers in hot climatic conditions. Four experimental rations having CP 23 (control group), 22, 21 and 20%, with optimal amino acid balance were prepared. All the four rations were isocaloric having ME 3200 kcal/kg with Energy: Protein (E:P) 139.0, 146.5, 152.4 and 160 in die...

Background: In recent years, dietary fat supplementation has become a common practice and fat supplemented diets have had variable effects on animal performance and carcass characteristics. OBJECTIVES: This study was conducted to determine the effect of  increasing the levels of sesame oil on performance, rumen parameters and plasma lipid profile in finishing Chal lambs. METHODS: Eighteen male ...

this study was conducted to investigate the effects of l-carnitine and different levels of animal fat on performance, carcass characteristics and some blood parameters of broiler chickens. two hundred one-day old male broiler chicks were allotted to5 treatments in 4 replicates and 10 birds in each replicate. dietary treatments consisted of: 1) diet with 5% vegetable oil (t1), 2) diet with 5% ve...

The objectives were to study the relationship between in vivo ultrasound measurements and cold carcass measurements at 4 anatomical points along the backbone of lambs and to determine appropriate regression equations to estimate carcass composition by using ultrasonic measurements at each anatomical point. The lambs (n = 114) used were suckling lambs (BW = 11.09 kg), light lambs (BW = 22.43 kg)...

Crossbred pigs (n=288) were used to test the interactive effects of dietary fat source and slaughter weight on dissected carcass composition and fatty acid composition of composite carcass samples. Pigs were blocked by initial BW, and within each of 9 blocks, pens (8 pigs/pen) were randomly assigned to either control corn-soybean meal grower and finisher diets (Ctrl) or diets formulated with 5%...
