Can milk replacer allowance affect animal performance, body development, metabolism, and skeletal muscle hypertrophy in preweaning dairy kids?

We aimed to evaluate performance, body development, metabolism, and expression of genes related to skeletal muscle hypertrophy in uncastrated male dairy kids fed with different levels of milk replacer (MR) during the preweaning period. Sixty newborn male kids, not castrated, from Saanen and Swiss Alpine breeds, with an average BW of 3.834 ± 0.

Effects of bovine somatotropin on productive performance and Minas Padrão cheese.

We aimed to evaluate the effects of two brands of bST (bovine somatoropin) on productive performance and on Minas Padrão cheese yield. Fifteen Girolando cows with more than 60 days of lactation were used. The animals were distributed in a randomized block design, according to days in milk, with three treatments (somatotropin A, somatotropin B, and control).
