| Popis: | Our current investigation was aimed to study differential influence of heat stress on defensive functions of blood polymorphonuclear cells among native and crossbred cows by culturing them in vitro after animal exposure to in vivo heat stress. Blood was collected from 18 cows which were divided in to three groups based on their breed as, group I (Sahiwal), group II (Tharparkar) and group III (Crossbred). THI was calculated by temperature and relative humidity (RH). PMN were isolated and were incubated at 38°C. Phagocytosis and lymphocyte proliferation was then investigated by NBT and MTT assays, respectively. The overall mean THI was significantly (p |
