| Abstract | ||
| Subclinical mastitis poses significant economic and production challenges in the dairy industry. This study aimed to evaluate the efficacy of ultrasonography in diagnosing subclinical mastitis by assessing changes in teat parameters and supramammary lymph nodes in 48 Holstein-Friesian cows. Inclusion criteria included a positive California Mastitis Test (CMT) and somatic cell count (SCC) between 200×10³/mL and 500×10³/mL. There were significant difference between (SMLNL, p<0.000), (SMLNW, p<0.000) and other morphological parameters of teat such as, (TW, p<0.008), (TWrF, p<0.001), (TC,p<0.010), (TWT,p<0.000), and ratio's of (TC/TW, p<0.000) and (TWT/TW, p<0.000) whereas in case of teat canal length there was non-significant difference (TCL, p<0.110). Ultrasonographic findings revealed significant differences in teat width, teat wall thickness, and supramammary lymph node dimensions (p<0.05) in subclinically affected animals. Ultrasound proved to be an effective and novel tool for morphological assessment and diagnosis of subclinical mastitis, offering a non-invasive method for early detection, management and prognosis of mastitis. | ||
