Resumo: The effects on calf performance of two sources of fat (milk fat and hydrogenated soybean oil) were studied in a series of eleven experiments. Twenty male holstein calves were used in a randomized block design with 10 replications. The experimental periods lasted from the 13th to the 89th days after birth. There were two treatments: hydrogenated soybean oil added to reconstituted powdered skim milk and reconstituted whole powdered milk. In addition to the liquid diets the animals were offered a commercial starter (24.4% crude protein), alfalfa hay (18,5% crude protein) and mineral mix. The results showed no difference on the overall body development between the two treatments. The average daily weight gains during the first month ranged from 146g to 327 g, and from 384g to 944 g during the remaining of the experimental period. The dry matter and protein intakes were somewhat higher than those recommended by NRC whereas the TDN was similar to the values published by the NRC. The measurements on wither height and hearth girth were of little aid to evaluate calf growth weekly.

The measurements on wither height and hearth girth were of little aid to evaluate calf growth weekly.Para testar o efeito da substituição da gordura do leite por gordura hidrogenada de soja, 20 bezerros, machos, holandeses, foram usados em um grupo de 11 experimentos delineados em bloco ao acaso, com dois tratamentos e 10 repetições num período compreendido entre o 13° e o 89° dia de vida. Além do sucedâneo 1, constituído de leite desnatado em pó acrescido de gordura hidrogenada de soja, ou de sucedâneo 2, constituído de leite integral em pó, os animais recebiam um concentrado comercial (24,4% de proteína à base de M.S.) feno de alfafa moído (18,5% de proteína à base de M.S.) e mistura mineral.Os resultados obtidos indicaram que a gordura hidrogenada de soja possibilitou um desenvolvimento corporal dos bezerros semelhante ao conseguido através da gordura do leite. Os ganhos de peso variaramentre 0,146kg e 0.327kg no primeiro mês e entre 0,384kg e 0,944kg no restante do período. O consumo de proteína e matéria seca mostrou-se ligeiramente superior ao preconizado pelas Normas de Alimentação, e o de nutrientes digestíveis totais, praticamente igual. As medições de altura da cernelha e o perímetro toráxico mostraram pouca sensibilidade para avaliar o crescimento em períodos de tempo curtos como uma semana.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraSilva, Aliomar Gabriel daFaria, Vidal Pedroso deGodói, Cássio Roberto de Melo2014-04-15info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/16846Pesquisa Agropecuaria Brasileira; v.12, n. único, 1977; 233-240Pesquisa Agropecuária Brasileira; v.12, n. único, 1977; 233-2401678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/16846/11172info:eu-repo/semantics/openAccess2014-04-15T19:09:34Zoai:ojs.seer.sct.embrapa.br:article/16846Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-15T19:09:34Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
