Background: High performance hybrid broilers require a high energy diet to exploit their full genetic potential. Therefore, high energy sources are being used in broiler diet which creates interest in the use of emulsifiers along with fat source. Hence, this study was conducted to evolve emulsifier supplementation strategy in low energy diet containing tallow as fat source in commercial broiler chickens. Methods: Total of 150 day old broiler chicks randomly distributed into three treatments with 5 replicates of ten chicks each. Treatment groups were fed basal diet which contains tallow as energy source (T1), basal diet supplemented with emulsifier at 250g per tonne of feed (T2) and 80 kcal Metabolizable energy reduced from basal diet supplemented with emulsifier at the rate of 250g per ton of feed (T3). Result: At 6th week of age significantly highest body weight was noticed in T2 group, lowest feed intake was recorded in T2 group but feed conversion ratio was comparable between T3 (1.72) and T2 (1.74) groups. No significant difference in carcass parameters and serum biochemical parameters were noticed. Emulsifier supplementation with reduced metabolizable energy can be used as a feeding strategy in broiler chickens to improve the production performance.

Ten villages of Tirunelveli district were selected purposively for the study wherein NABARD Farmers culb functioning successfully. From each village 50 NABARD Farmers club members were selected by simple random sampling techniques. Thirty percent of the respondents were involved among 500 beneficiaris of the project to study the impact of TANUVAS - mineral mixture on the productive performance. Accordingly, 15 respondents from each village were included for this study and constituted a sample size of 150. Milk sample were collected before supplementation of TANUVAS - mineral mixture and after two weeks period of supplementation of TANUVAS - mineral mixture in dairy cattle. Fat and SNF percentage of samples were analysed in the laboratory and milk yield also estimated. The study concluded that, supplementation with TANUVAS - mineral mixture increased milk yield by one litre, fat percentage increased by 1.77 per cent and SNF increased by 0.77 per cent.
