摘要: Aim: The present study was aimed to investigate the relationship of udder shape, teat-end teat length, and diameter with intra-mammary infection in Jersey crossbred cows under hot-humid climate. Materials Methods: A total 24 lactating were evaluated for shape (pendulous/regular) (flat/inverted/pointed) by visual examination, while length measured using vernier caliper. Monthly milk sampling done 4 months duration. Few quarters found as blind or nonfunctional so, a 366 quarter wise samples collected at monthly interval subjected somatic cell count (SCC) microscopically. data on SCC transformed into log scale analyzed. Results: There significant (p<0.01) effect level. mean level pendulous significantly (p<0.05) higher compared regular shaped udder. Similarly, flat shape. correlation between well diameter. Conclusion: In conclusion, udder, inverted teat-end, very long thick more susceptible these traits must be considered accordingly selecting dairy animals future production.
