body weight laying hen laying performance egg quality traits
2015/6/5
This study was carried out to investigate the effect of different body weight groups (light (L) = 1 400–1 500; medium (M) = 1 500–1 600 and heavy (H) = 1 600 < g) on performance and egg quality traits...
The effect of sex and slaughter weight on intramuscular fat content and its relationship to carcass traits of pigs
pig carcass intramuscular fat sex slaughter weight correlations
2015/6/4
Carcass quality and intramuscular fat content of castrates and gilts are compared and a possible dependence of intramuscular fat content on sex and slaughter weight is determined in the pig population...

cattle random regression heritability genetic correlation growth curve linear spline
2015/6/4
6 508 bulls of dual-purpose cattle at performance-test stations were weighed at intervals of 30 days from birth to 420 days. After all editing a total of 74 558 weight records were available. Live wei...
Carcass and meat quality in Brown fattened young bulls: effect of rearing method and slaughter weight
Brown cattle carcass composition meat colour sensory evaluation
2015/6/2
Three groups of Brown fattened young bulls were studied, comparing the effects of rearing method (suckled vs. bucket reared) and of slaughter weight (400 vs. 480 kg). Suckled animals had higher fatnes...
