				Abstract 
 
				
				
				Aim: 
				
				The present study was conducted to explore the effect of 
				supplemental heat on mortality rate, growth performance, and 
				blood biochemical profiles of indigenous Ghungroo piglets in 
				sub-tropical cold and humid climatic conditions of Tripura, a 
				state of the north eastern hill (NEH) region of India. 
				
				
				Materials and Methods: 
				
				The experiment was conducted on 38 indigenous Ghungroo piglets 
				from birth up to 60 days of age. Among the 38 piglets, 19 
				piglets were provided with supplemental heat ranging between 
				17.0°C and 21.1°C for the period of the first 30 days and 
				thereafter between 24.1°C and 29.9°C for the next 30 days. The 
				other 19 piglets were exposed to natural environmental minimum 
				temperatures ranging between 7.2°C and 15.0°C during the first 
				30 days and then between 18.5°C and 25.5°C for the next 30 days. 
				
				
				Results: 
				
				The supplemental heat resulted in 10.6% reduction of piglet 
				mortality from the 2nd till the 7th day of age. These beneficial 
				effects could be related with the lower (p<0.05) plasma 
				glutamate pyruvate transaminase (GPT) and cortisol levels and 
				higher (p<0.05) plasma alkaline phosphatase (AP) concentrations 
				in heat supplemented group compared to control group. Plasma AP, 
				GPT, glucose, triiodothyronine, and luteinizing hormone 
				concentrations decreased (p<0.05) gradually with the advancement 
				of age in both control and supplemental heat treated piglets. 
				
				
				Conclusion: 
				
				Supplemental heat could be beneficial since it is related to a 
				reduction of piglet mortality during the first week of life 
				under farm management system in the sub-tropical climate of NEH 
				region of India.
