Resumo: The objective of this study was to evaluate the effects of two levels of maize silage and extruded soybeans supplementation on fatty acid profile in milk fat of dairy cows. Eight Holstein cows were distributed in a double 4x4 Latin Square design with a factorial arrangement. The treatment groups were: high maize silage and low lipid, high maize silage and high lipid, low maize silage and low lipid and low maize silage and high lipid. The experimental periods lasted 21 days. Milk samples were collected on days 18 and 19 of each experimental period. The increase of lipid contents in high and low maize silage diets decreased short chain fatty acids concentrations (C4:0 - C12:0). The conjugated linoleic acid content (cis-9 trans-11 C18:2) increased from 3.72 to 4.85, and 4.6 to 5.89mg/g, when extruded soybeans was used in high and low level of corn silage, respectively. The increase in dietary lipids content resulted in higher trans-11 C18:1 fatty acid concentration. Fatty acid trans-10 C18:1 tended to increase with the elevation of the lipids content in the diet. There was significant correlation between trans-10, cis-12 C18:2 and milk fat percentage. The extruded soybeans supplementation decreased shortchain fatty acids and palmitic acid in milk. In addition, this oilseed enhanced the concentration of conjugated linoleic acid (C18:2 cis-9 trans-11) and vaccenic acid, which improved the milk quality for the human health.

Oito vacas da raça Holandesa foram distribuídas em um quadrado latino duplo 4 x 4, em arranjo fatorial. Os tratamentos foram: alta silagem de milho e baixo lipídio, alta silagem de milho e alto lipídio, baixa silagem de milho e baixo lipídio e baixa silagem de milho e alto lipídio. Os períodos experimentais tiveram duração de 21 dias cada. As amostras de leite foram coletadas nos dias 18 e 19 de cada período experimental. O aumento dos teores de lipídios nos dois níveis de silagem diminuiu as concentrações de ácidos graxos de cadeia curta (C4:0 - C12:0). O teor de ácido linoleico conjugado (cis-9 trans-11 C18:2) aumentou de 3,72 para 4,85, e de 4,60 para 5,89mg/g, quando a soja extrusada foi utilizada em dietas com alto e baixo nível de silagem de milho, respectivamente. O aumento no teor de lipídios na dieta resultou em maior concentração de trans-11 C18:1. O ácido graxo trans-10 C18:1 tendeu a aumentar com a elevação do teor de lipídios na dieta. Houve correlação significativa entre trans-10, cis-12 C18:2 e percentual de gordura do leite. A suplementação com soja extrusada diminuiu os ácidos graxos de cadeia curta e o ácido palmítico no leite. Além disso, esta oleaginosa aumentou a concentração de ácido linoleico conjugado (C18:2 cis-9 trans-11) e vacênico, com o aumento da qualidade do leite para o consumo humano.Universidade Federal da Bahia2020-11-20T15:15:08Z2020-11-20T15:15:08Z2012info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfOLIVEIRA, M.
