Addition de lipides protégés (encapsulés ou savons de calcium) à la ration de vaches laitières. Effets sur les performances et la composition du lait

Abstract: L’une des limites à l’utilisation des matières grasses dans l’alimentation des ruminants tient aux perturbations qu’elles engendrent dans la digestion des glucides dans le rumen. Pour éviter cet inconvénient, diverses formes de protection des lipides sont apparues. Cet article récapitule les effets de l’addition des graisses animales (en moyenne 941 g/j) et d’huiles végétales (693 g/j) encapsulées, et de savons de calcium (593 g/j), dans la ration des vaches laitières sur les quantités ingérées, la production … Show more

“…The ability to better control milk fat content and composition is central to improving both the nutritional quality of dairy products, as some fatty acids (FA) have potential positive or negative effects on human health (Givens, 2015;Ferlay et al, 2017), and the production efficiency of dairy ruminants. In recent decades, the addition of lipid supplements to ruminant diets has been used to improve energy intake in highproducing dairy cows (Chilliard et al, 1993) and to influence milk FA composition (Doreau et al, 2012). However, certain dietary conditions in dairy cows; (1) diets rich in starch (e.g., high-grain/low-forage diets) and supplemented with PUFA from plants or (2) diets supplemented with PUFA of marine origin (mainly fish oils and algae) cause milk fat depression (MFD; Bauman and Griinari, 2001), whereas others, such as dietary addition of calcium salts from palm oil, increase milk fat content (Mosley et al, 2007).…”
