The Comparison of Sweating Rate and Sweat Gland Anatomy between Simmental and Its Crossing with Ongole Crossbred (Simpo) Bulls

The purpose of this study was to find out the sweating rate and anatomy of the sweat glands of Simmental and their crossing with the Ongole cross bred (SimPO) bulls. The research was conducted in Authorized Slaughter House of Gadang, Malang City and the Bioscience Laboratory of University of Brawijaya. The material used were 4 Simmental, and 5 SimPO bulls with an average weight of ≥300 kg and age of ≥2 years. Sweating rate data were collected use Cobalt Chloride Disc. The anatomy of the sweat gland skin samples were observed in the Bioscience Laboratory. Data sweating rate obtained were analyzed statistically using unpaired t-test. The result showed there was significant difference (P<0,05) of sweating rate between Simmental and SimPO bulls. The sweat gland of Simmental have a smaller size and tubular likes shape than SimPO. The SimPO has a large and baggy sweat gland.
