NAVES, A.B. et al. Performance and plasma profile of dairy cows fed full or processed whole raw soybean in diets. Arch. zootec. [online]. 2013, vol.62, n.240, pp.579-588. ISSN 1885-4494.  https://dx.doi.org/10.4321/S0004-05922013000400010.

The objective of this study was to evaluate the effects of different forms of use of processed or full whole raw soybean in different ground of screens and their effects on dry matter intake, milk yield and composition and blood parameters. Twelve Holstein cows were grouped in three balanced 4x4 Latin squares and fed the following diets: 1) control (C), 2) whole raw soybean (GI), 3) ground soybean 2mm (G2) and 4) ground soybean 4 mm (G4). A reduction in dry matter intake in cows fed diets containing whole raw soybean or ground in relation to the control diet. The parameters of production and milk composition were not affected by the experimental diets. There was no effect of diets for cows on concentrations of blood parameters, glucose, urea, blood urea nitrogen (NUS), total protein, albumin and hepatic enzymes aminotranferase aspartate (AST) and gamma glutamyl transferase (GGT) except for total cholesterol and HDL-cholesterol. The processing of whole raw soybean did not affect the performance and plasma profile of midlactation dairy cows.

Keywords : Metabolism; Milk composition.
