Effects of Osmotic and Hydrostatic Pressures on Milk and Antimicrobial Substance Production in Lactating Goats

Animal Science Journal, Volume 97, Issue 1, January/December 2026.
ABSTRACT Osmotic and hydrostatic (intramammary pressure) pressures within the mammary gland may stimulate mammary epithelial cells and leukocytes, which alter milk production and immune functions. We aimed to clarify the effects of different volumes and concentrations of NaCl solution on milk and antimicrobial substance production in lactating goats ...

A retrospective cohort study investigating the association of postcalving intramammary infection and milk yield, somatic cell count, clinical mastitis, and culling risk in first-lactation dairy cows

Journal of Dairy Science
: The objective of this study was to investigate the association of postcalving IMI with milk production and SCC during the first 3 test days after calving, as well as the risk of clinical mastitis occurrence and culling within the first 100 DIM in first-
