Live weight and ultrasound measures of fat thickness and longissimus muscle area were available on 404 yearling bulls and 514 heifers, and carcass measures of weight, longissimus muscle area, and fat thickness were available on 235 steers. Breeding values were initially estimated for carcass weight, longissimus muscle area, and fat thickness using only steer carcass data. Breeding values were a...

The growth performance and the carcass and physical and chemical characteristics of the meat of 24 Landrace X Large White pigs were compared when reared under a free-range or a conventional housing system. The free-range pigs had lower feed intakes and slower growth rates than the conventionally housed pigs. The free-range pigs also had a lower P2 fat depth and therefore yielded a carcass with ...

________________________________________________________________________________ Abstract The effect of sex and the supplementation of the prebiotic, mannan oligosaccharides (MOS), the acidifier, calcium propionate (CPr) or their combination in the feed of Japanese quail (Coturnix japonica) on their performance and carcass quality was examined in this experimentation. Three hundred, 1-day old J...

Real-time ultrasound measurements (Falco 100 device, linear probe 3.5 MHz) were used to estimate in vivo carcass composition of Hungarian Merino (n=9) and British Milksheep (n=10) ram-lambs. Animals aged 110-120 days and were growing 29.73+/-1.11 kg and 28.98+/--0.95 kg, resp. There were little between-breed differences in the ultrasound records for subcutaneous fat thickness (0.33+/-0.10 cm; 0...

the effect of genotype, sex and hatch on carcass traits and physical characteristics of eggs was investigated in the japanese quail. two strains of japanese quails including the white (p1) and wild (p2) genotypes were chosen as the parental generation and crossed reciprocally (10 single-pair mating) to create the f1 progeny. the f1 birds (27 males and 81 females) were mated randomly to produce ...

Estimates of heritabilities and genetic correlations were obtained for weaning weight records of 23,681 crossbred steers and heifers and carcass records from 4,094 crossbred steers using animal models. Carcass traits included hot carcass weight; retail product percentage; fat percentage; bone percentage; ribeye area; adjusted fat thickness; marbling score, Warner-Bratzler shear force and kidney...

Quality carcass and non-carcass are two inseparable components that result from slaughtering animals with high economic value. The aims study is effect of polimorfisme DGAT1 gene on hot cold carcass, neck traits in Indonesia sheep. A total 50 rams used this were collected 10 Barbados Cross Sheep (BCS), Compass Agrinac (CAS), 15 Javanese Thin-Tailed (JTTS), Jonggol (JS). sheep slaughtered at 10-...

little scientific information is available that has evaluated safflower (carthamus tinctorius) cake as a substitute to conventional ingredients in small ruminants diet. the objective of this work was to evaluate the effect of feeding safflower cake in total mixed rations (tmrs) on lamb and kid growth rates, carcass traits and meat fatty acid composition. two consecutive trials were conducted us...

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...

Crossbreeding of Holstein–Friesian dairy cows with both early maturing (e.g. Aberdeen Angus (AA)) and late maturing (e.g. Belgian Blue (BB)) beef breeds is commonly practised. In Ireland, genetic merit for growth rate of beef sires is expressed as expected progeny difference for carcass weight (EPDCWT). The objective of this study was to compare the progeny of Holstein–Friesian cows, sired by A...
