Beschreibung

Dietary lipid supplements in ruminant diets, whether from various natural sources or
supplements such as rumen protected lipids, have a long history and are widely used. The main reasons for using these supplements include an increased energy density of dairy cow diets, e.g. in the early stage of lactation (Clapperton and Steele, 1983). Moreover, reproductive parameters might are affected as well by using lipid supplements, either indirectly by changes in the energy balance of cows or directly due to the effects of certain fatty acids (FA) on reproductive organs and processes (Leroy et al., 2014).
