Abstract:
Somatic cell count (SCC) in milk has been shown to be an excellent marker for subclinical mastitis but very difficult to execute at farm level. Due to the damage to the udder tissue, concentrations of Milk Constituents Changed and concentrations of Na+ and Cl- increases in milk which results in increase in electric conductivity and pH. The present investigation was carried out to investigate the correlation of milk Constituents, pH and electric conductivity with somatic cell count and can be used as an indicator to detect subclinical mastitis (SCM) in 105 lactating Sirohi goats maintained under arid region of Rajasthan at Sheep Breeding Farm, Fatehpur, Sikar. Total 210 milk samples were screened for somatic cell count, electrical conductivity (EC), pH and milk Constituents by deluxe electric conductivity meter manufactured by Systronics India limited, Ahmadabad pH meter and ultrasonic milk analyzer manufactured by Rajasthan Electronics & Instrument Limited (REIL), Jaipur respectively. The result demonstrated statistically significant (p<0.01) increase in electric conductivity, pH and fat percentage while significant (p<0.01) decrease in milk lactose. From the results a conclusion can be made that electrical conductivity and milk lactose exhibits a high correlation with SCC scores and can be used as the tools to predict subclinical mastitis at farm level.
