Summary

The use of radiant energy in reducing energy expenditure for thermo-regulatory needs during the cool season was studied in weaned kids of black, dark tan and white goat colours and adult goats of black colour. The daily gain in live weight was higher in weaned kids receiving 8 h daily exposure to solar radiation than their contemporaries kept inside a shed. The difference in daily live weight gain between the kids of two groups was more in black and dark tan colour kids than those of white colour kids.

During the period of exposure to solar radiation metabolic rate in kids of the exposed group was lower than in the unexposed group. The magnitude of decrease in metabolic rate was more in kids of black coat in comparison to kids of white coat. Resting metabolic rate in black Kutchi adult goats also decreased on exposure to solar radiation during cool season.

Feed conversion efficiency was also better in kids exposed to solar radiation in comparison to those housed in the shed. Higher magnitude of decrease in metabolic rate and improvement in feed conversion efficiency in dark colour kids than white kids explained role of coat colour in utilization of solar energy for thermo-regulatory needs in cool season and thereby saving some feed energy for higher growth rates.
