“…González and Bas (2002) used hydrogenated fish oil and observed an increase in milk production but no change in protein and fat. Goodman et al (2003), supplemented protected palm oil with calcium salt and reported no change in fat or protein, but did not discuss the amount of milk produced. Schroeder et al (2003) used calcium salts and observed no differences in production or protein content but a decrease in fat.…”

This study was conducted to evaluate if supplementing bypass fat to cows under silvopastoral systems, increases the concentration of unsaturated fatty acids in milk, thus improving the saturated/ unsaturated ratio without a negative effect on total milk yield in fat or protein. Two concentrations of two different sources of bypass fat were evaluated for 40 days, each in a group of 24 multiparous Lucerna (Colombian breed) cows. A cross-over design of 8 Latin squares 3 x 3 was used. The variables submitted to analysis were body condition, daily milk production and milk composition. Body condition, milk yield and milk quality were not different but there was a significant decrease in the amount of saturated fatty acid in both experiments while the unsaturated fat increased significantly in experiment 1 and remained stable in experiment 2. Results, such as these have as far as we know, not been reported previously and they provide an approach for the improvement of milk as a "functional food".
