This study aims to compare anatomies of Madagascar chickens (indigenous race and Starbro strain). With 8,262 individuals of either indigenous races or Starbro strain chickens raised in a suburban environment, the weights of different pieces of cut as well as the live weights before slaughter were determined. Results showed that breast development presents a positive linear relationship with thi...

Abstract Little is known about how fiber quality impacts rumen health in feedlot diets with minimal forage inclusion. The objective of the study to investigate interaction between undigestible NDF (uNDF) levels and grain fermentability (GF) on animal performance, feeding behavior, ruminal pH steers. Using a 2x2 factorial design, Angus crossbred steers (n=96, 505±54 kg) were fed an isonitrogenou...

The National Longitudinal Study of Adolescent Health data were used to test predictions from life history theory. We hypothesized that (1) in young adulthood an emerging life history strategy would exist as a common factor underlying many life history traits (e.g., health, relationship stability, economic success), (2) both environmental harshness and unpredictability would account for unique v...

The present study was carried out to study the carcass and meat quality traits of two breeds of [New Zealand White (NZW) and Californian (CAL)] under environmental conditions in Egypt. Two hundred of NZW and CAL (100 rabbits of each bread of 50 males and 50 females) aged and slaughtered at 12 weeks .The following traits were recorded: body weight at slaughter age carcass weight, meat, fat and a...

In this study, meat quality traits were compared between Chinese lard- and European lean-type pigs. The association between expression of four genes (ADSL, GARS-AIRS-GART, DGAT1, and DECR1) and meat quality traits was also investigated. Meat quality traits were found to differ significantly between pig breeds. Meat color parameter values (a* and b*) and intramuscular fat content in Anqingliubai...

The objective of this study was to characterize breeds representing diverse biological types for postweaning growth and carcass composition traits in terminal crossbred cattle. Postweaning growth and carcass traits were analyzed on 434 steers and 373 heifers obtained by mating F1 cows to Charolais sires. Maternal grandsires represented Hereford, Angus, and MARC III (1/4 Hereford, 1/4 Angus, 1/4...

Th is study investigated the relationships between ultrasound measurements of backfat thickness (UBF) taken on live heavy pigs and several carcass composition and ham quality traits. Before slaughter 240 pigs were weighed (average BW: 167 ± 10 kg) and assessed for UBF using an A-mode ultrasonic device (placed above the last rib at approximately 5.5 to 8.0 cm from midline, with increasing distan...

OBJECTIVE This experiment was conducted to investigate the effects of crude glycerin from waste vegetable oil (CGWVO) on performance, carcass traits, meat quality, and muscle chemical composition. METHODS Twenty-four crossbred (Thai Native×Anglo Nubian) uncastrated male goats (16.8± 0.46 kg body weight [BW]) were assigned to a completely randomized design and subjected to four experimental di...
