摘要: CertaindietsinduceMFDinlactatingdairycowsandseveraltheories havebeenproposedasthebasis.Oneoftheseistheglucogenic-insulin theory, but recent investigations offer no support for this theory as the cause of MFD. Another is that intermediates formed in rumen biohydrogenation unsaturated fatty acids inhibit fat synthesis at mammary gland. Recent studies suggest pathways are altered under certain dietary conditions and results a shift CLA transC18:1 isomers produced. Specifically, diet-induced MFD corresponds to increases milk content trans-10, cis-12CLA trans-10 C18:1, former has been shown be potent inhibitor synthesis.
