Abstract
The present study was conducted to evaluate the morphological changes of sweat gland of indigenous Kangayam cows over crossbred Jersey cow during different climatic conditions. About six numbers of adult Kangayam and Jersey breeds of cattle in the age range of 3 to 5 years were selected from farmer’s house in the vicinity of Namakkal and Sathyamangalam districts of Tamil Nadu. The skin biopsy samples were collected in both the breeds during winter (December – February 2018) and summer (April- June 2019) seasons. Histological measurements like, sweat gland length, sweat gland diameter, depth of sweat gland and sweat gland density were recorded with the help of trinocular microscope (Leica DM 1000) with image analyzer (Leica application suit) software. The results revealed that the significant (P<0.01) increase in length and diameter and number of sweat glands in Kangayam cows than Jersey cows during both environmental conditions. Whereas depth of the sweat gland was less in Kangayam cow than Jersey cow during both seasons. The observations clearly indicating the more evaporative cooling capacity of indigenous cow over cross bred Jersey cow.
