Abstract:
The present study was designed to ascertain the effect of different seasons on serum hormonal and electrolytes profile in Mandya sheep. Study was conducted at Livestock Research and Information Centre, Nagamangala. Eight apparently healthy Mandya sheep with same physiological condition was selected and maintained in same managemental condition throughout the study period during each season. Temperature relative humidity index (THI) was calculated by utilizing the meteorological data on temperature and relative humidity for different seasons. Blood samples were collected once in each season during peak of the season. Hormonal parameters were analyzed by indirect ELISA method and serum electrolytes by reagents and kits. During different study periods, highest THI (%) of 79.17±0.31 was recorded in summer and intermediate value of 73.12±0.33 % was observed during rainy season and the lowest in winter. The serum T3 and T4 was significantly (P<0.05) higher at winter season compared to summer and rainy season. No significant difference was noticed between summer and rainy season. The level cortisol was significantly higher at summer and winter seasons compared to rainy season and also significantly higher levels was noticed in summer as compared to winter season. The mean value of serum insulin was significantly lower at summer season compared to winter and rainy season. The serum sodium, potassium and chloride level was significantly (P<0.05) lower during summer season compared to rainy and winter season. So, present findings confirms that both hot and cold ambient temperature is stressful to the sheep and negatively correlated growth and reproductive performance.
