Teorias sobre a síndrome da baixa gordura no leite de vacas: ácidos graxos trans, biohidrogenação, insulina glicogênica.

Two proposed categories summarize the basis for diet-induced milk fat depression (MFD): those who consider reduced milk fat production as a consequence of an insufficient supply of precursors for the synthesis of fat mammary gland lipids of milk, and those that attribute the reduction in milk fat to a direct inhibition of one or more steps in the synthesis of milk fat from the mammary gland. Theories of the former category included: reduced production of acetate and β-hydroxybutyrate in the rumen by limiting de novo mammary fatty acids synthesis. The theory that has gained support over the last decade is that milk fat mammalian synthesis is inhibited by the only fatty acid that is produced as a result of changes in the rumen biohydrogenation or by direct trans fatty acids inhibition resulting from incomplete dietary biohydrogenation of rumen unsaturated fatty acids
