To investigate the relationship between chemical composition of meat from the carcass cuts and thewhole carcass, 48 nine-month-old randomly selected ram lambs of Ghezel and Mehraban (24 rams per breed)were used in a trial arranged as a 2 × 2 factorial experiment with two breeds and two feeding levels (high andlow), in a completely randomized design. After 80 days, all animals were slaughtered a...

the objective of the present study was to investigate the effects of dietary l-arginine on performance, meat production and its chemical composition, carcass fat deposition, intestine morphology and blood parameters of ross broiler chickens during 46 days. in this experiment, 192 day old commercial female ross broiler chicks were used with 4 dietary treatments and 4 replications in a completely...

The current study was conducted to investigate the effects of genetic and non-genetic factors on body weight and carcass traits of Japanese quails. Two strains of Japanese quail (150 wild quails and 150 white quails) were used as base population. Four mating groups were used to produce progenies: wild male × wild female, white male × wild female, wild male × white female and white male × white ...

Effects of breed type and sex on the fatty acid composition of subcutaneous neutral lipid and intramuscular neutral and phospholipids of longissimus lumborum muscle were investigated using 145 steers and 82 heifers that consisted of pure Japanese Black and Holstein and crossbreds among Japanese Black, Holstein, Japanese Brown, and Charolais. Steers and heifers were reared on a high plane of nut...

effect of two fattening systems were studied on feedlot performance and carcass characteristics of using of 66 fars native male kids in different ages. six kids were slaughtered at the first day of experiment and sixty kids were divided into two groups. the first group were kept in feedlot in individual pens and the second group grazed on rangeland, and after 3 months, were kept in feedlot in i...

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%...

to investigate the possibility of using ultrasound to estimate carcass composition, 38 moghani male lambs were made use of. subcutaneous fat depth (usft) and longissimus dorsi muscle depth (ulmd) and area (ulma) were assessed in the site between 12th and 13th ribs by using ultrasound equipped with an 8 mhz probe. the lambs were then slaughtered. carcasses were cold stored at 4°c for 24 hours an...

Body and carcass composition were studied on 10 male and 10 female naturally reared llamas (Lama glama). Half the animals were young (9-12 months) and the other half adult (>3 year). The average live weights for young and adult males were 104.4 and 100.6kg, and for females 67.6 and 104.6kg, respectively. Average carcass weights for the four groups were 58.9, 56.2, 36.8 and 56.7kg, respectively....
