EFFECT OF MASTITIS ON MILK COMPOSITION OF CROSS-BRED (HOLSTEIN FRIESIAN X CHOLISTANI) AND SAHIWAL CATTLE

The present study was designed to investigate the effect of mastitis on various components including fat percentage, protein, total solids, solid not fat, pH, specific gravity and lactose content in milk cross-bred (Holstein Friesian × Cholistani) Sahiwal cattle. A 376 samples (excluding blind nonfunctional teats) from 100 cows (50 50 sahiwal) were collected aseptically. Animals different ages, parity stages lactation selected under field condition. diagnosis subclinical done basis Surf Field Mastitis Test. For bacterial examination milk, grown laboratory biochemical tests performed. results indicated that (SNF) mastitic sahiwal cattle solids percentage normal significantly reduced as severity increased animals. pH both severe cases mastitis. showed there no significant difference compared normal. protein concentration findings highlighted cause major alterations composition leading poor quality milk.
