abstract
The study entitled “Effect of subclinical mastitis on milk composition in lactating cows” was conducted to determine the effect of subclinical mastitis on milk quality. This experiment was conducted during May to June, 2018 on a total of 80 lactating dairy cows. The study was designed with the objective to determine the Milk samples were collected and analyzed using ULTRASONIC EKOMILK MILK ANALYZER Instrument. The study showed that chemical properties of milk samples were pointed out are pH, fat, protein, lactose, solid not fat (SNF), total solids and acidity were significantly (p>0.05) with severity of mastitis. The pH and acidity significantly increased in subclinical mastitis milk samples as compared to normal milk samples whereas a significant decreases were recorded in the fat, protein, lactose, solid not fat (SNF) and total solids percent in subclinical mastitis milk samples as compared to normal milk samples of non- affected cows from mastitis disease. A total of 80 cows were screened against subclinical mastitis in cows at dairy farm, Banaras Hindu University, Varanasi.
