Growth efficiency in early stages of life of animals is an important factor in productive efficiency.The overhead charges of maintenance of animals till it reaches productive stage accounts for economic rearing of livestock. Smaller size animals like goats which give both milk and meat grow faster and attain 50 per cent mature weight in less than 8 to 9 months time.- Influence of Dietary Energy on the Body Composition and Feed Conversion Efficiency during Growth in Goats

Heat stress is a condition that is caused by worker over-exposure to the high temperature work environments often found in outdoor agriculture operations. Wet bulb globe temperature (WBGT) is a measure of heat stress especially when it is above 27°C. Considering the range of temperatures prevalent in the Rajasthan state of India during the months of May and June, agricultural operations during these months and the associated heat stress on the agricultural workers, this study was designed to ascertain the effect of WBGT on physiological cost of operation for agricultural workers. Southern Rajasthan was selected to conduct this study. Different WBGT of 28°C, 29°C, 30°C, 31°C and 32°C were selected for this study. The study conducted on twelve farm workers reveals that WBGT induces heat stress on the bodies of workers. The resting, working and delta heart rates and resting and working oxygen consumption rates of workers increased with increase of WBGT from 28°C to 32°C. The resting hear rate, working heart rate and ΔHR was found increasing linearly with wet Bulb globe temperature with higher correlation. Resting and working OCR were also having increasing linear relationship with wet bulb globe temperature.Keywords

Rajasthan state is in west region of India. Maximum temperatures rise sharply exceeding 45° C by the end of May and early June resulting in harsh summers in the state. Heat stress is a condition that is caused by worker over-exposure to the high temperature work environments often found in outdoor agriculture operations. Wet Bulb Globe Temperature (WBGT) is a measure of heat stress. Considering the range of temperatures prevalent in the Rajasthan state during the months of May and June, agricultural operations during these months and the associated heat stress on the agricultural workers, this study was designed to ascertain the effect of WBGT on body thermal responses of agricultural workers. Southern Rajasthan was selected to conduct this study. The study was conducted on 12 farm workers. Different WBGT of 28°C, 29°C, 30°C, 31°C and 32°C were selected for this study. Thermal parameters included head, forehead and oral temperature. Forehead temperature was observed to decrease with an increase in WBGT. Heavy sweating was observed at high WBGT and this resulted in the decrease in skin and forehead temperature. Oral and head temperature was observed to increase with increase in WBGT. Since oral temperature is also considered to be the core temperature of body, it increased with increase in WBGT. Head absorbs the direct solar radiations and hence, its temperature increased with increase in WBGT.Keywords
