Veterinary Medicine and Science, Volume 9, Issue 1, Page 336-344, January 2023., 2023 The high‐yielding dairy cows suffer from insulin resistance during the periparturient period. Dietary supplementation of pioglitazone hydrochloride, an insulin‐resistance drug and synthetic agonist for PPRAγ, improved the insulin sensitivity index (RQICKI‐BHBA) in Holstein dairy cows during the transition period. Abstract Background High‐yielding dairy

Regulation of Milk Protein Synthesis by Free and Peptide-Bound Amino Acids in Dairy Cows
Biology, 2021 Milk protein (MP) synthesis in the mammary gland of dairy cows is a complex biological process. As the substrates for protein synthesis, amino acids (AAs) are the most important nutrients for milk synthesis.

An attempt to define the sodium requirements of lactating dairy cows in a tropical environment [PDF]
, 2011 BACKGROUND: Lactating dairy cattle in the tropics may require more sodium (Na) owing to the hot and humid climatic conditions. It is unknown whether the current recommendations on Na for lactating cows can be quantitatively used in tropical countries ...

Antipenicillinase in the Serum of Dairy Cows [PDF]
Acta Veterinaria Scandinavica, 1980 Serum from dairy cows was tested for inhibitory effect on penicillinase from a penicillin-resistant Staphylococcus aureus strain of mastitic origin. Among cows with subclinical mastitis caused by penicillin-resistant S. aureus there was a significantly higher frequency of individuals with penicillinajse-inhibiting serum than among healthy cows.
