OBJECTIVE To determine the effect of feeding frequency and cow-specific factors on diurnal variations of blood metabolites concentrations. ANIMALS 40 dairy cows from 2 herds. PROCEDURE Each herd was fed concentrate at a specific feeding frequency (automatic vs twice daily). Blood samples were collected 4 times daily. Plasma concentrations of glucose, nonesterified fatty acids (NEFA), and beta-hydroxybutyrate (BHBA) were analyzed, and concentrations of urea, cholesterol, and total protein… CONTINUE READING
