Abstract :

Influence of mineral supplementation on the performance of Madras Red lambs reared under intensive and semi-intensive systems of management was studied. The lambs supplemented with minerals on daily or weekly basis under intensive system had significantly (P<0.05) heavier body weights than the unsupplemented group. There was no significant difference (P<0.05) in the serum albumin and total protein levels between the treatment groups. The serum cholesterol showed no significant difference (P<0.05) between treatment groups on 0 and 45th day of rearing, whereas on the 90th day the lambs maintained under intensive system had a significantly (P < 0.05) higher level of cholesterol when compared to semi-intensive system. Serum calcium and phosphorous levels had linear relationship with the supplementation of minerals. The lambs supplemented with minerals on daily or weekly basis had significantly higher serum minerals. It was concluded that the supplementation of mineral mixture had resulted in better growth rate and average daily gain than the unsupplemented groups in both the systems of management. However, mineral supplementation was found to have no influence on all the carcass traits and the blood profile studied.
