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.
