dc.description.abstract | A study was conducted to evaluate the effects of solar radiation on some physiological parameters (body temperature, respiration rate, pulse rate and panting score), blood metabolites and average daily gain in two breeds of sheep (Deccani and Nellore). The experiment was conducted at Hayathnagar Research Farm of Central Research Institute for Dryland Agriculture (17o27’N latitude and 78o35’E longitude and about 515m above sea level) during May to July months in the year 2012 and involved 18 ram lambs divided into 2 groups of similar age (152 ± 6.1d) and body weight (15.1±1.06kg). The rams were exposed to solar radiation from 0900hrs to 1500hrs during the study period. Heat load index (HLI) was maximum (P<0.05) in May (93.9 ± 0.85) compared to July (88.7 ±0.37) month. Significantly (P<0.05) higher body temperature, pulse and respiration rate, panting score was observed in both the breeds as HLI was highest in May, however impact was more pronounced in Deccani than Nellore breed. Exposure of sheep to heat stress evoked a series of radical changes in the biological functions, which include a decrease in feed intake, efficiency and utilization, disturbances in protein, energy and mineral balances, hormonal and blood metabolite levels. Heat stress severely affected body weight gain and resulted in lower average daily gain in ram lambs and a significant difference was observed among two breeds. The present study confirms breed differences in susceptibility to heat stress as manifested by physiological alterations and subsequent effect on productivity. | en_US |
