Brazil is a major pork producer, with increasing market demands driving heavier slaughter weights. Sexual condition well stablished factor influencing pig performance, carcass composition, and quality, previous studies focusing primarily on lighter pigs. This study compared the characteristics, traits of heavy-slaughtered barrows gilts. A total 144 pigs (72 barrows; 72 gilts), an average weight 55.68 ± 6.48 kg, were utilized in randomized complete block design. They allocated into 48 pens...
This study aimed to determine the effect of supplementation with chondroitin sulfate (CS) and manganese (Mn) on performance bone quality broiler chickens. A total 1,152 male Cobb chicks were housed for 47 days in a completely randomized design arranged 4x3 factorial scheme: four levels CS (0.00, 0.06, 0.12, 0.18%: kg CS/kg ration) three Mn (0, 40, 80 mg/kg), totaling 12 treatments eight replicates birds each. Dietary chickens influenced (P>0.10) feed conversion, linear increase this...
Abstract The goal of this study was to evaluate the effect contrasting growth rate in pre and post-weaning period on carcass traits meat quality feedlot Nellore cattle. To high weight gain, period, were be considered management groups with mean gain above third quartile pre-weaning (PREW) or (PROW) distribution population group moderate lots daily average gains between first quartiles PREW PROW population. In low will lower than We used a total 500 bulls, registered National Association...
Abstract The goal of this study was to evaluate the performance and carcass traits Nelore cattle progenies from bulls selected by contrasting for precocity, growth muscularity, through Expected Progeny Difference (EPD). One hundred five (initial weight 350kg±15kg) 20 months age were confined fed with same diet (73% concentrate). Thirty-two animals create groups muscularity (16 assigned as a low EPD group - LEPD 16 high HEPD), based on their parents. ribeye area backfat thickness performed...
