INVESTIGATING THE CORRELATION BETWEEN UDDER AND LEG HYGIENE SCORES AND SUBCLINICAL MASTITIS IN DAIRY COWS

Abstract

Dairy production is a major contributor to the economy of Anand district in Gujarat, India. However, subclinical mastitis continues to be a significant challenge faced by dairy farmers. This study investigated the relationship between udder and leg hygiene scores and the incidence of subclinical mastitis in lactating crossbred cows. The study sampled 200 cows from 13 different dairy farms in the district. Subclinical mastitis was assessed by collecting approximately 10ml of foremilk sample from each quarter during evening milking, and udder and leg hygiene scores were assessed during milk sample collection. The study found a linear increase in the incidence of subclinical mastitis with an increase in udder and leg hygiene scores. Specifically, cows with higher udder hygiene scores (UHS) and leg hygiene scores (LHS) had higher incidences of subclinical mastitis, with UHS 4 and 5 and LHS 4 and 5 having 20% and 22% higher incidences of subclinical mastitis, respectively, compared to UHS 1 and LHS 1. The results reveal the significant impact of dairy farming practices on milk quality, udder health, and animal welfare in Anand district. The findings also highlight the need for improved milking practices, including regular teat dipping, to reduce the incidence of subclinical mastitis
