Abstract
The present study was conducted on thirty six samples of teat of Kosali cows procured from central plain region of the Chhattisgarh state and divided into two groups - lactating and non-lactating/ non-pregnant stages with eighteen cows in each group. Lactating and non-lactating/ non-pregnant stages were further categorized as early, mid and late groups, each with six animals. The lining epithelium of teat cistern was mostly cuboidal with patches of bistratified cuboidal and columnar in lactating and non-lactating Kosali cows. Mucosa showed mostly circular folds in lactating and longitudinal folds in non-lactating stage. The stratum corneum of the epidermis was apparently two times thicker in lactating than non-lactating stage. In both stages, Furstenberg’s rosette were lined by cuboidal, bistratified cuboidal and stratified squamous nonkeratinized epithelium. The teat canal was lined by a stratified squamous epithelium in initial part, distally keratinization was increased. The percentage decrease in the different parameters between mid and late stages was higher (60%) as compared to early and mid stages (40%) in lactating as well as non-lactating Kosali cow.
