Forty male Omani lambs were used in a feeding trial to study the effects of feeding diets containing various levels of metabolizable energy (ME) on growth and carcass composition. Ten lambs were selected randomly and slaughtered at the start of the trial to provide information on initial carcass composition. Thirty lambs were divided randomly into three groups and fed three diets varying in ME ...

the objective of this study was to determine the effect of different levels of chicory root and stem powder (crsp) and butyric acid (ba) combination on the performance, carcass traits, relative weight of internal organs and some blood parameters in broiler chickens. two hundred and forty one-day-old broilers (ross 308) were used in a completely randomized design with four treatments with six re...

The effects of estradiol and progesterone on food intake, body weight, carcass adiposity, and adipose tissue lipoprotein lipase (LPL) activity were investigated in weanling female rats. Treatment with estradiol benzoate (EB) reduced body weight gain in ovariectomized (OVX) weanlings as it does in adults. However, other responses to EB were attenuated or absent in weanlings. EB treatment did not...

Ninety-two swine averaging 104 +/- 4.5 kg and 99 cold carcasses averaging 75 +/- 3.1 kg were measured with a four-terminal plethysmograph. Pigs were transported to the abattoir, fasted 4 h, weighted, and measured for body resistance (Rs, omega), body reactance (Xc, omega), and distance (L, cm) between detector terminals that were located along the dorsal axis of the animal. Pigs were slaughtere...

Five hundred and forty crossbred (Korean native black pig×Landrace) F2 were selected at a commercial pig farm and then divided into six different coat color groups: (A: Black, B: White, C: Red, D: White spot in black, E: Black spot in white, F: Black spot in red). Birth weight, 21st d weight, 140th d weight and carcass weight varied among the different coat color groups. D group (white spot in ...

Objectives were to 1) evaluate genetic relationships of sex-specific indicators of carcass merit obtained using ultrasound with carcass traits of steers, 2) estimate genetic parameters needed to implement combined analyses of carcass and indicator traits to produce unified national cattle evaluations (NCE) for longissimus muscle area, subcutaneous fat depth, and marbling with the ultimate goal ...

The aim of the present study was to derive multiple regression equations for in vivo estimation of the carcass lean and fat content in Muscovy ducks. The experimental materials consisted of 240 White Muscovy ducklings (120 male and 120 female). One hundred sixteen females aged 10 wk and 112 males aged 12 wk were slaughtered. Before slaughter the ducks were weighed, and the following body measur...

the present study was carried out to establish the relationships between carcass yield and some body measurements in lori goat breed. the first body weight (bw) and morphological traits of 186 heads goat were recorded. the animals were then slaughtered to calculate the carcass yield. results showed the colinearity among the traits. in order to eliminate colinearity problems, principal component...

Abstract The aims of this study were to determine the prevalence carcass lesions in slaughtered pigs and quantify their relationships with different animal characteristics, pre-slaughter factors, blood measurements, performance indices, composition meat quality traits. Data was recorded for 30 journeys referring 1080 market-weight that originated from 15 commercial small-scale finishing farms. ...
