Abstract

 Milk samples in an aseptic manner at the beginning of DRY PERIOD and three days after parturition from 124 mammary quarters (37 cows) were collected to determine somatic cell count (SCC). All quarters were scored (1 to 5) on the basis of teat–end hyperkeratosis to establish a correlation between the score and new infection rate and SCCs. After the last milking, a commercial intramammary antibiotic was used for all quarters. In this study critical value of 250000cell/ml was set for SCCs. Samples with somatic cell count lower and greater than this critical value were considered healthy and infected respectively. The statistical analysis showed 26.5% new infection rate and 5% cure rate at 3 days after parturition. The score were 1, 2, 3 and greater than 3 for 40%, 36%, 21% and 3% of evaluated teats respectively. There was significant difference between milk SCC at the beginning of the DRY PERIOD and SCC of three days after parturition (p=0.0005, r=0.8) Statistical analysis also showed significant differences between teat-end hyperkeratosis and SCC at the same periods (p=0.0005, r=0.66).There was no significant differences between teat score and new infection rate (P>0.05).
