Effect of lipid sources on dry matter intake and fatty acid profile of bovine milk

Abstract

The following work analyzes the most important and relevant information on the effect of lipids in diets for lactating cows. Additionally, their influence on dry matter intake and other parameters such as milk production and the fatty acid profile in milk fat was investigated and deepened. Lactating cows after calving are in a state of negative energy balance because the animal decreases intake but simultaneously increases production. Therefore, supplementation with lipid sources becomes an efficient tool, as they contain a higher energy content compared to starch-rich sources, increasing milk production once energy intake increases or improving energy utilization efficiency. Furthermore, supplementation with lipid sources is viable as they improve the fatty acid profile in milk and, in some cases, in meat, thereby bringing beneficial effects to consumers of animal products and also generating added value.
