Resumo: | The processing of oats grain (entire or grounded) on the performance of feedlot finished cull cows was studied. Cows were fed with 60% of corn silage and 40% of concentrate, composed by oats grain, urea, limestone and salt. The treatments were Treatment 1 with whole oats grain, Treatment 2 with 50% grounded grain, e Treatment 3 with 100% grounded grain. The data were analyzed by regression. Grinding did not affect dry matter intake, being the average values 10.563 kg/animal/day, 2.2% when expressed per 100 kg of live weight and 102.94 g when expressed per metabolic weight. Average daily weight gain increased linearly with the inclusion of grounded oats in the diet (Y=.79976+.0033X), while feed conversion declined linearly (Y=13.21155-.04021X). Subcutaneous fat thickness increased lenarly with the increase of grounded oats in the diet. The better use of the grounded oats resulted in higher weight gain and slaughter weight, which explains the higher fat deposition of cows fed with grounded oats.KEY WORDS: Feed conversion, intake, weight gain. |

As vacas foram alimentadas com 60% de silagem de milho e 40% de concentrado, composto por grãos de aveia-preta, ureia, calcário calcítico e cloreto de sódio. A forma como se forneceram os grãos aos animais representaram os tratamentos, ou seja, Tratamento 1 com grãos de aveia fornecidos inteiros, Tratamento 2 com 50% dos grãos fornecidos moídos, e Tratamento 3 com 100% dos grãos fornecidos moídos. Os dados foram submetidos à análise de regressão polinomial a 5% de significância. A moagem da aveia não influenciou o consumo dos animais, que apresentaram consumo de 10,563 kg/dia, ou 2,2% quando ajustado para peso vivo e 102,94 g por unidade de tamanho metabólico. O ganho de peso apresentou comportamento linear com a substituição do grão inteiro por grão moído (Y=0,79976+0,0033X), influenciando diretamente a conversão alimentar, que apresentou comportamento linear decrescente (Y=13,21155-0,04021X). Os valores médios de ganho de peso foram de 0,799, 0,967 e 1,129 kg/animal/dia e de conversão alimentar de 13,203, 11,217 e 9,182, respectivamente. A espessura de gordura subcutânea aumentou linearmente com o aumento da inclusão da aveia moída na dieta. O melhor aproveitamento dos grãos moídos conferiu aos animais maior aporte de energia digestível, resultando em maior ganho de peso e peso de abate, fatores que explicam a maior deposição de gordura.PALAVRAS-CHAVES: Consumo, conversão alimentar, ganho de peso.Universidade Federal de Goiás2009-07-03info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionAvaliado por paresPesquisa Científicaapplication/pdfhttps://revistas.ufg.br/vet/article/view/387710.5216/cab.v10i2.3877Brazilian Animal Science/ Ciência Animal Brasileira; Vol. 10 No. 2 (2009); 497-503Ciência Animal Brasileira / Brazilian Animal Science; v. 10 n. 2 (2009); 497-5031809-68911518-2797reponame:Ciência animal brasileira (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGporhttps://revistas.ufg.br/vet/article/view/3877/4838Restle, JoãoFaturi, CristianPascoal, Leonir LuisRosa, Joilmaro Rodrigo PereiraBrondani, Ivan LuizAlves Filho, Dari Celestinoinfo:eu-repo/semantics/openAccess2013-11-07T11:47:04Zoai:ojs.revistas.ufg.br:article/3877Revistahttps://revistas.ufg.br/vetPUBhttps://revistas.ufg.br/vet/oai||revistacab@gmail.com1809-68911518-2797opendoar:2024-05-21T19:55:11.665184Ciência animal brasileira (Online) - Universidade Federal de Goiás (UFG)true |
