Journal ArticleDOI
Conjugated linoleic acid is synthesized endogenously in lactating dairy cows by Delta(9)-desaturase.

TL;DR: Results demonstrate that endogenous synthesis of CLA from trans-11 18:1 represented the primary source of CLA in milk fat of lactating cows.
Journal ArticleDOI
Trans-Octadecenoic Acids and Milk Fat Depression in Lactating Dairy Cows
TL;DR: Dietary fiber concentration and type of fat had significant effects on milk fat, and the addition of unsaturated fat resulted in marked increases in the milk fat content of trans-11-octadecenoic acid, regardless of dietary fiber concentration; however, marked milk fat depression occurred only when the low fiber diet was supplemented with uns saturated fat.
Journal ArticleDOI
Role of Insulin in the Regulation of Mammary Synthesis of Fat and Protein
TL;DR: Results offer no support for the glucogenic-insulin theory of milk fat depression but do indicate that the insulin infusion, either directly or indirectly, enhanced secretion of milk protein.
Journal ArticleDOI
Role of Insulin in the Regulation of Milk Fat Synthesis in Dairy Cows
TL;DR: It is demonstrated that a relatively constant rate of milk fat synthesis was maintained during chronic hyperinsulinemia, and effects on milk fat yield and composition of fatty acids offered no support for the role of insulin on milkfat depression.
Journal ArticleDOI
Demonstration of a role for insulin in the regulation of leptin in lactating dairy cows.
S. S. Block,Robert P. Rhoads,Dale E. Bauman,RA Ehrhardt,Mark A. McGuire,Brian A Crooker,J. M. Griinari,T.R. Mackle,Wanda J Weber,M.E. Van Amburgh,Yves R. Boisclair +10 more
TL;DR: It is suggested that, in undernourished lactating dairy cows, reduced plasma insulin could account for a portion of the decline in plasma leptin but that elevated plasma GH is unlikely to have a major effect.
