Determinación de la eficiencia del peróxido de hidrógeno como alternativa de yodados como pre-selladores para desinfección de pezones en bovinos de leche para evitar el ingreso de microorganismo que producen mastitis bovina.

Abstract

Bovine milk is a basic food for human beings, which requires quality standards related to sanitary, physicochemical and microbiological aspects. The aim of this study was to evaluate the efficiency of hydrogen peroxide as an alternative to iodine in the pre-sealing technique as one of the processes related to the sanitary quality of milk. A dairy herd was selected in the south of the province of Pichincha, with mechanical milking, defined milking routine and Good Farming Practices (GFP) certification. Two groups were formed, each with 15 cows in different productive stages: one group with hydrogen peroxide treatment and another group with iodine with pre-sealing application. Streptococcus agalactiae, Streptococcus uberis, Staphylococcus aureus (Gram positive), Klebsiella sp, Escherichia coli, and Pseudomonas sp (Gram negative) were identified in the study; after the application of iodine as a pre-seal the teat bacterial load decreased against that of hydrogen peroxide; the percentage effectiveness was higher for iodine than that of hydrogen peroxide. Compliance with good milking practices (GMP) is of vital importance as it ensures udder health and milk quality.
