Duodenal flows of protein, essential amino acids in dairy cows

The objective of this analysis was to compare the rumen submodel predictions of four commonly used dairy ration programs to observed values of duodenal flows of crude protein (CP), protein fractions and essential AA. FULL STORY »

The association of serum metabolites in the transition period

The objective was to examine the associations of peripartum concentrations of nonesterified fatty acids (NEFA), ß-hydroxybutyrate (BHBA) and calcium with milk production in early lactation and pregnancy at the first artificial insemination (AI) across different management systems. FULL STORY »
