The objective of this work was to verify the effect of lipids sources (whole soybean meal – WSM; and soybean oil – SBO) added to the diet on changes in milk production and its physical-chemical characteristics. Six multiparous 7/8 Holstein-Zebu cows, averaging 30 days post calving, 500 kg body weight and daily milk production of 20 l were used. The animals were divided into three groups and received three isoproteic and isocaloric diets (treatments): control (3% ether extract), WSM (7% ether extract) and SBO (7% ether extract). There were no treatment effects on any measured parameters. The results on the physical-chemical analysis of the milk were within the range of allowed values by Brazilian regulation of industrial inspection and sanity of products of animal origin.
