Resumo: | Early weaning (EW) has been adopted in cattle breeding farms in Pantanal as a strategy to increase the rate of pregnancy in cows. The primary income of these properties is the production of beef calves, and the price of these animals depends on their weight. Therefore, the calves subjected to EW should present weight similar to or higher than those of calves subjected to conventional weaning (CW). This study aimed to evaluate the productive performance of pure (Nellore) calves and crossbred (Nellore/Angus) calves reared in the Pantanal and subjected to either EW or CW. After EW, the calves were supplemented with concentrate at 1 kg/animal/day (low-energy diet) or 1% of live weight (high-energy diet). The weights adjusted to 300 days of age were higher for EW calves fed the high-energy diet (p<0.01) in both genetic groups. No significant differences were observed in the weight of EW animals fed the low-energy diet and CW animals (p>0.01), and animal weight was 241.17 and 236.27 kg in crossbred calves and 184.44 and 189.78 in Nellore calves, respectively. The EW adopted in this experimental model did not affect the productive performance of calves raised in the Pantanal.Keywords: Nutrition, beef calves, supplementation. |

A principal receita dessas propriedades são os bezerros (as), sendo o seu valor dependente dos seus respectivos pesos. Assim é necessário que os bezerros submetidos à DP, apresentem pesos semelhantes ou acima dos bezerros desmamados convencionalmente. Desta forma o estudo teve como objetivo, acompanhar o desempenho de bezerros nascidos no Pantanal, submetidos à DP ou a desmama convencional (DC), puros (Nelore) ou Cruzados (Nelore/Angus). Após a DP os animais receberam suplemento específico para bezerros, na quantidade fixa de 1 kg/animal/dia (baixa energia) ou ao nível de 1% do Peso Vivo (alta energia). Os pesos ajustados aos 300 dias de idade foram maiores para os bezerros de DP sob alta energia (P<0,01), em ambos os grupos genéticos. Os pesos dos animais de DP de baixa energia e de DC, não se diferiram (P>0,01), sendo de 241,17 e 236,27 kg para o grupo de bezerros Cruzados e de 184,44 e 189,78 para o grupo de bezerros Nelore respectivamente. A DP adotada no modelo experimental não prejudicou o desempenho dos bezerros nascidos no Pantanal.Palavras-chave: Nutrição, bezerros de corte, suplementação.Universidade Federal de Goiás2019-01-18info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPesquisa Científicaapplication/pdftext/htmlhttps://revistas.ufg.br/vet/article/view/e-5118710.1590/cab20151187Brazilian Animal Science/ Ciência Animal Brasileira; Vol. 20 (2019): Continuous publication; 1-12Ciência Animal Brasileira / Brazilian Animal Science; v. 20 (2019): Publicação contínua; 1-121809-68911518-2797reponame:Ciência animal brasileira (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGengporhttps://revistas.ufg.br/vet/article/view/e-51187/27091https://revistas.ufg.br/vet/article/view/e-51187/27092Copyright (c) 2019 Ciência Animal Brasileirainfo:eu-repo/semantics/openAccessOliveira, Luiz Orcirio Fialho deAbreu, Urbano Gomes Pinto deGomes, Rodrigo da CostaNogueira, ÉriklisSilva, Juliana Correa BorgesCosta, Tereza Gabriela2023-03-23T18:49:21Zoai:ojs.revistas.ufg.br:article/51187Revistahttps://revistas.ufg.br/vetPUBhttps://revistas.ufg.br/vet/oai||revistacab@gmail.com1809-68911518-2797opendoar:2024-05-21T19:56:21.486142Ciência animal brasileira (Online) - Universidade Federal de Goiás (UFG)true |
