Full TextAbstract
Supplementing the diet of cows with long chain unsaturated lipid decreased the medium chain fatty acids (10:0, 12:0, and 14:0) and increased the 18:0 and 18:1 content of milk fat with the greatest decrease when a high linoleic acid source was fed. Fish oil which contains relatively high concentrations of two polyunsaturated fatty acids of the n-3 family: eicosapentaenoic acid (EPA, C20:5) and docosahexaenoic acid (DHA, C22:6), is an effective means of increasing milk fat CLA content, due to an inhibition of trans C18:1 reduction in the rumen that results in an increased supply of trans-11 C18:1 available for endogenous conversion in the mammary gland. The combination of marine lipids with plant oils is an established strategy for increasing milk fat CLA content (Palmquist and Griinari, 2006). Lipids from canola seeds contain about 6% C16:0 and as high as 58% cis-C18:1, which have potentially interesting characteristics to change fatty acids profile of milk fat. Our objective was to evaluate the effects of feeding fish oil and canola oil separately and in combination on the fatty acid profile of milk fat and on the yield and composition of milk from dairy.
