To determine the influences of season, distance and multiple-farm loads on pigs transported to slaughter under Spanish commercial conditions, 496 journeys, involving 90,366 pigs, were analysed. Mortality, liveweight loss, transport yield, killing out percentage, carcass yield after overnight chilling and percentage of condemned and trimmed carcasses were recorded. Season significantly affected ...
The aim of the research was to establish quantitative and qualitative indicators meat productivity Simmental bull calves various constitutional types when raised using technology beef cattle breeding. maximum growth rate highest yield products were obtained from bulls dairy type they fed according Receiving mothers for 205 days sucking period more fatty milk, gave 1250 g gain per day reached 28...
Prenatal and pre-weaning growth and nutrition of cattle: long-term consequences for beef production.
Severe, chronic growth retardation of cattle early in life reduces growth potential, resulting in smaller animals at any given age. Capacity for long-term compensatory growth diminishes as the age of onset of nutritional restriction resulting in prolonged growth retardation declines. Hence, more extreme intrauterine growth retardation can result in slower growth throughout postnatal life. Howev...
A total of 576 mixed-sex pigs (PIC 327 × 1,050; initial BW = 55.8 ± 5.5 kg) were used to determine the effects of corn dried distillers grains with solubles (DDGS) and wheat middlings (midds) withdrawal 24 d before harvest in diets without or with ractopamine HCl (RAC) on growth performance, carcass characteristics, and carcass fat quality. From d 0 to 49, pigs were fed a corn-soybean meal-base...
Brahman cattle are important in tropical regions due to their ability to tolerate excessive heat and parasites. However, Brahman cattle exhibit lower carcass quality characteristics when compared to Bos taurus breeds. The objective of this study was to evaluate potential associations between single nucleotide polymorphisms (SNPs) in six candidate genes for carcass quality and composition traits...
A total of 144 male crossbred calves were allocated to four management treatments (bulls; steers; bulls implanted with zeranol at 100 d of age and re-implanted at 69, 93 and 56 d thereafter; bulls implanted with zeranol at 168 d of age and re-implanted at 93 and 56 d thereafter), and two pre-slaughter shipping treatments (minimum pre-slaughter stress with cattle shipped and slaughtered within 4...
Effect of dietary protein lowering and supplementation peppermint extract on yield, carcass, blood parameters microbial population broiler chickens
An experimental study in 180 day-old broiler chicks was conducted to evaluate efficacy of herbal liver tonic & growth promoter products on overall growth, performance and carcass quality parameters. Day old chicks were randomly divided into three groups, control group I was given no treatment while group II & III were administered herbal liver tonic & growth promoter products Superliv DS & Xliv...
Carcass traits of beef cattle have been genetically improved to increase yield of high quality meat. Genome-wide association study (GWAS) is a powerful method to identify genetic variants associated with carcass traits. For the 770K genotyped SNPs from 1141 Chinese Simmental cattle, we used the compressed mixed linear model (CMLM) to perform a genome-wide association study for knuckle, biceps a...
