dc.description.abstract The objective of this study was to explore hypotheses of the mechanism by which NEL stimulates MPY in cows and to determine if glucogenic and lipogenic substrates stimulate MPY by similar mechanisms. Five rumen-fistulated Holstein cows were randomly assigned to a 5 x 5 Latin square design. Treatments were CTL, LoG, HiG, LoA and HiA. Glucose infusion for 5 to 7 d tended to increase milk and protein yields and increased lactose yield. Milk yield, protein yield and lactose yield decreased during acetate infusion. Glucose infusion affected expression of mammary genes related to cell proliferation, differentiation and protein accretion capacity while supplement acetate affected expression of milk protein genes, and those related to protein accretion capacity and cell differentiation. en_US
