Abstract

Mastitis in a single quarter can cause high somatic cell counts (SCC), clinical mastitis, and death in dairy cows. Casein hydrolysate (CH) is an intramammary (IMM) infusion treatment reported to induce mammary involution. Objectives were to study cessation of milk production in one mastitic quarter per cow following CH IMM infusion, 3-quartered cow milk production and cow-level SCC for the remainder of lactation, and after calving, whether the mastitic quarter resumed milk production, cow and quarter-level milk production, SCC and elimination of previously isolated mastitis pathogens.
