Two experiments were conducted in order to determine the effect of dietary fatty acid profile on deposition of body fat, carcass fat, and separable fat depots. Diets with four types of fat (tallow, olive, sunflower, and linseed oils) at an inclusion level of 10% were administered to female broiler chickens. In Experiment 1, total body fat, carcass fat (total body fat minus abdominal fat), and a...

Five single nucleotide polymorphisms (SNP) of the chicken insulin-like factor binding protein 2 (IGFBP2) gene were selected to genotype a F2 designed population with restriction fragment length polymorphisms and single stranded-conformation polymorphisms. The associations of the SNP and their haplotypes with chicken growth and carcass traits were analyzed. Results showed that the difference ind...

Salmonella contamination of poultry is a global public health problem. The objective of this study was to map the distribution of Salmonella on the young chicken carcass, to improve poultry inspection and food safety. Young chickens (n = 70) in the Cornish game hen class were obtained at retail over a 3-year period. Carcasses were aseptically sectioned into 12 parts, and then Salmonella was iso...

This study was conducted to determine the effect of soaked and dried false yam seed meal (SFYSM) on the carcass and sensory characteristics of broiler chicken. A total of 48 chickens (12 birds in each treatment) were randomly selected from 120 birds fed diets containing 0% (T1, control), 5% (T2), 7.5% (T3) and 10% (T4) SFYSM. The birds were weighed and slaughtered after a 24 hours feed withdraw...

i’ire behaviour plays a very important role in vehicle dynamic studies. Because of the complexity of tire structure, some tire models use so many assumptions they cannot represent tire behaviour well, while others are so complicated they are di@icult to use in engineering applications. This study presents an analytical tire side slip modeI with flexible tire carcass which is very helpful for un...

This study examined carcass and meat quality parameters in growing/finishing pigs fed unconventionally versus the concentrate-based system. Ninety-six, 12 wk old pigs (34±SD 0.3 kg) were randomly divided into three groups, assigned to one of the three dietary treatments: standard complete concentrate mixture, conventional (C diet); unconventional, steamed potato-green forage-concentrate based d...

Fatty acid composition and carcass traits of 2,275 Japanese Black steers and heifers were analyzed to estimate the heritabilities and genetic correlations using the REML procedure. Slices of LM at the 6th to 7th rib section were minced and homogenized, and total lipids were extracted for the analysis by a gas chromatograph. Oleic acid accounted for the majority (51.3%), followed by palmitic (26...

The objective of this study was to investigate single nucleotide polymorphisms (SNPs) in the bovine nephroblastoma overexpressed (NOV) gene and to evaluate whether these polymorphisms affect carcass traits in the Korean cattle population. We resequenced to detect SNPs from 24 unrelated individuals and identified 19 SNPs within the full 8.4-kb gene, including the 1.5-kb promoter region. Of these...

One hundred twenty 4-mo-old wether lambs born to Targhee ewes and sired by six rams each from Merino (Finewool, FM and Strongwool, SM), Rambouillet (Dubois, DR and Texas, TR), and Targhee (T) breeds were randomly assigned to predetermined slaughter weight groups of 43, 48, 52, and 57 kg and evaluated for growth and carcass traits. Overall mean ADG and feed conversion rate (FC, kilograms of feed...

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...
