Abstract:
Accumulation of casein-derived peptides to critical concentration in milk stored in the mammary gland induces the process of mammary involution in the gland. The ability of casein hydrolyzates (CNH) to dry-off milk secretion in infected mammary quarters and cure microbial infection was evaluated. Lactating cows, infected by various common pathogens in one quarter and having an average somatic cell count (SCC) of 2,000,000 were treated. An infected quarter was infused with 10 ml of CNH (prepared under GMP conditions) three consecutive times, 24 h apart, after milking. Treatment accelerated and synchronized the natural involution process as reflected by rapid dry-off of milk secretion in 35 out of 37 cows within 3 days. Dramatic changes in the composition of mammary secretion: disappearance of lactose and fat and accumulation of whey proteins with components of the innate immune system were observed. The bactericidal activity of mammary secretion of treated glands, which started within 8 h, persisted after the 3 day course of CNH treatments protocols. Immediate success resulting in SCC of less than 400,000 in the three functional glands in post-treated cows was 85%. After parturition, 78% of the treated quarters were bacteria free. Thus, CNH appears as an effective tool to improve milk hygiene in cows exposed to subclinical and chronic mastitis and to eliminate bacterial infection. The latter properties of CNH treatment also suggest that it may be used as an effective non-antibiotic dry treatment for cows. © Wageningen Academic Publishers The Netherlands, 2005.
