Ribeiro,Julimar do Sacramento; Ladeira,Marcio Machado; Machado Neto,Otavio Rodrigues; Campos,Fabrício RodriguesObjetivou-se avaliar a predição de consumo de matéria seca (CMS) pelos sistemas CNCPS 5.0, NRC e BR-CORTE, bem como o consumo de nutrientes por tourinhos zebuínos confinados. Foram utilizados 44 animais em delineamento experimental inteiramente casualizado, sendo: 19 Nelore PO, 7 Nelore LA, 10 Tabapuã PO e 8 Guzerá PO, com peso vivo inicial médio de 394 ± 39; 348 ± 33; 346 ± 28 e 340 ± 30 kg, respectivamente, e...

Ribeiro,Julimar do Sacramento; Gonçalves,Tarcisio de Moraes; Ladeira,Márcio Machado; Tullio,Rymer Ramiz; Campos,Fabrício RodriguesThe objective of this study was to study the animal reactivity and correlate it with performance and meat quality of cattle finished in feedlots. A total of 20 animals of the Tabapuã breed and 20 animals of the Nellore breed were confined for 112 days: 28 days of adaptation and 84 days of data collection. Performance was determined by the average daily weight gain (ADG) and average dry matter intake (DMI) estim...

Ribeiro,Julimar do Sacramento; Gonçalves,Tarcisio de Moraes; Ladeira,Márcio Machado; Campos,Fabrício Rodrigues; Tullio,Rymer RamizThe objective of this study was to evaluate the residual feed intake (RFI) and its relation with performance, carcass and meat characteristics of Zebu animals. A total of 40 Zebu steers with initial age of 18 months and initial live weight of 350 kg were confined in feedlot for 112 days. The average daily gain (ADG) and dry matter intake (DMI) were obtained every 14 days. Residual feed intake was determined by ...

Machado Neto,Otávio Rodrigues; Ladeira,Márcio Machado; Chizzotti,Mário Luiz; Jorge,André Mendes; Oliveira,Dalton Mendes deThe objective of this research was to evaluate average daily gain (ADG), carcass traits, meat tenderness and profitability of keeping cattle fed different oilseeds and vitamin E in feedlot. A total of 40 Red Norte young bulls with initial average body weight of 339±15 kg were utilized. The experimental design was completely randomized in a 2 × 2 factorial arrangement. The experiment lasted 84 days and experimen...

Garcia,Iraides Ferreira Furusho; Almeida,Amélia Katiane de; Costa,Tharcilla Isabella Rodrigues; Leopoldino Júnior,Izac; Ribeiro,Julimar do SacramentoThis work aimed at determining the influence of roughage proportions and fat source of the diet on characteristics of carcass and comercial cuts of lambs. It was used 24 non-castrated Santa Inês male lambs, ad libitum fed diet with two proportions of roughage (30 and 70%) and fat (no fat, protected fat, and soybean) slaughtered at an avarage body weight of 35.4 kg (± 1.5 kg). Animals fed 30% roughage diet showe...
