Resumo: | The objective of this work was to evaluate the performance in live weight gain (LWG) and economic of Nellore heifers in two strategies of alimentary supplementation: energy-protein (EP) and urea-salt (US). Twelve heifers with approximately twenty months old and initial live weight 306+21 kg were evaluated. The heifers had been kept in renewed pastures of Brachiaria brizantha cv Marandu. The duration of the experiment was of 55 days. The LWG and LWG/ha (live weight gain for hectare) were evaluated. For the economic analysis was considered operational cost, gross revenue, gross margin and the financial return direct. The heifers of EP showed 0.71 kg/animal/day higher than 0.43 kg/animal/day for SU (P |

Utilizaram-se doze novilhas, com idade média de vinte meses e peso vivo médio inicial de 306+21kg. As novilhas foram mantidas em pastagens renovadas de Brachiaria brizantha cv Marandu. A duração do experimento foi de 55 dias. Avaliaram-se o ganho médio diário (GMD) e o ganho de peso vivo por hectare (GPV/ha). Para a análise econômica, consideraram-se o custo operacional, a receita bruta, a margem bruta e o retorno financeiro direto. O GMD foi de 0,71 kg/animal/dia para as novilhas do EP e de 0,43 kg/animal/dia para SU, apresentando diferença significativa. Embora tenha havido melhor desempenho em ganho de peso nas novilhas suplementadas com energia e proteína, tal resultado não foi confirmado no desempenho econômico.Palavras-chaveS: Desempenho econômico, ganho em peso, recria de novilhas, suplementação energético-proteica.Universidade Federal de Goiás2009-07-02info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionAvaliado por paresPesquisa científicaapplication/pdfhttps://revistas.ufg.br/vet/article/view/349110.5216/cab.v10i2.3491Brazilian Animal Science/ Ciência Animal Brasileira; Vol. 10 No. 2 (2009); 485-496Ciência Animal Brasileira / Brazilian Animal Science; v. 10 n. 2 (2009); 485-4961809-68911518-2797reponame:Ciência animal brasileira (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGporhttps://revistas.ufg.br/vet/article/view/3491/4837Jung, Luiz Carlos StahnkeLouvandini, HélderMartha Júnior, Geraldo Buenoinfo:eu-repo/semantics/openAccess2009-07-03T14:37:09Zoai:ojs.revistas.ufg.br:article/3491Revistahttps://revistas.ufg.br/vetPUBhttps://revistas.ufg.br/vet/oai||revistacab@gmail.com1809-68911518-2797opendoar:2024-05-21T19:55:07.809615Ciência animal brasileira (Online) - Universidade Federal de Goiás (UFG)true |
