RELATIONSHIP OF B-MODE ULTRASONOGRAPHY FEATURES OF THE MAMMARY GLAND AND TEAT WITH CALIFORNIA MASTITIS TEST FINDING AND SOMATIC CELL COUNT IN DAIRY BUFFALOES (Bubalus bubalis Linnaeus, 1758) WITH SUBCLINICAL MASTITIS

Abstract

The ultrasound appearance of the udder from buffalo with subclinical mastitis consisted of hypoechoic parenchyma with anechoic gland cistern, alveoli, and lactiferous duct. In the normal mammary gland of buffalo, the udder revealed hyperechoic parenchyma with interspersed anechoic alveoli and lactiferous ducts. Teat of buffalo with subclinical mastitis revealed homogenous hypoechoic features of the three-discrete layer of the parenchyma. The teat in animals without subclinical mastitis showed hyperechoic to hypoechoic features of the teat wall. The mean ± SD echo mean values of the mammary gland and teat with subclinical mastitis were relatively higher than the echo mean values in the mammary gland and teat without subclinical mastitis. Pearson’s correlation showed a positive correlation between ultrasound echo mean values of the udder and CMT finding and ultrasound echo mean values of the udder and porta SCC. Also, the study showed a positive correlation between the ultrasound echo mean values of the teat and CMT findings and between the ultrasound echo mean values of the teat and SCC results. The results of the study suggest that ultrasonography can be useful in detecting subclinical mastitis in dairy Murrah buffaloes.
