Effect Of Feeding

There are too many physiological and nutritional factors which can influence lactation performance of early lactation Holstein dairy cows. Supplemental fat sources are utilized in rations for dairy cows as a common method to increase the energy density of the diet, especially in early lactation (Juchem et al., 2007). The fat sources also have a positive effect on milk fatty acid profile. Canola seed which contains 40% fat is an excellent source of dietary fat high in unsaturated fatty acids and protein for dairy animals. Canola oil contains 51% oleic, 25% linoleic, and 14% linolenic acids. Fish oil contains relatively high concentrations fatty acids of the n-3 family. It seems that feeding a blend of different oils will have more positive productive response than individual usage of them. The aim of this study was to evaluate the effect of feeding diets containing fish oil and canola oil starting from transition period on milk production and composition of early lactating Holstein cows.
