The results showed that the incidence of subclinical mastitis in dairy herd were 31.42% and the clinincal positive example in those animals comes to 10.60%. The subclinical mastitis cows increased as the dariy parturient and lactation time increased. The positive rate of subclinical mastitis is higher at the left mammary gland than that of the right one, also,the positive rate of the front mammary gland is higher than that of the back one. The productivity and economic benefit were dropped sharply caused by this chronic disease?It is necessary for the herd to be often checked with clinical and laboratory method. |
