ABSTRACT: For beef semen usage on dairy cows, much of the research has focused on the performance of the crossbred calves, yet little focus has been given to the subsequent performance of the cow herself. This study aimed to evaluate the performance

ABSTRACT: In the United States, lactation milk yields are not measured directly but are calculated from the test-day milk yields. Still, test-day milk yields are estimated from partial yields obtained from single milkings. Various methods have been p

Coleus amboinicus L. leaf (CAL) could reduce the rate of amino acid deamination and protein degradation within the rumen. This phenomenon would hopefully increase the amount of protein that passes through the rumen to the abomasum. Therefore, it migh
