Abstract
Subclinical mastitis is a major cause of economic loss in dairy herds that shows no
gross inflammatory changes in udder. Often it is more prevalent than the clinical
mastitis and it affects milk production and milk quality. Hence the study was
undertaken to evaluate the effect of subclinical mastitis in apparently healthy 60 Jersey
cross bred dairy cows in Theni District of Tamil Nadu. The mean SE values of SCC
levels in dairy cows with subclinical mastitis was 4.02 ± 0.12 x 105 cell / ml of milk
and 1.24 ± 0.21 x 105 cell / ml of milk in case of non-infected healthy dairy cows. The
mean SE value of chloride content of apparently healthy non infected cows was 0.15
± 0.004 g % compared to the samples suspected for subclinical mastitis with chloride
content of 0.21 ± 0.006 g %. The mean SE value of milk pH in apparently healthy
non infected cows was 6.51 ±0.04, whereas the samples suspected for subclinical
mastitis had pH of 7.57 ± 0.023, which indicated the likelihood of subclinical mastitis
in Jersey cross bred dairy cows.
