2011
Sunil Kumar | Yadav, M.C.
The present genetic studies of profit traits in Indian buffaloes were taken on 1753 Murrah, Nili Ravi and graded Murrah buffalo maintained at 6 military dairy farms. The data were collected from history sheets of buffaloes, which were progeny of 185 sires and were calved during 195384. The costs of expenditure were calculated as per normal requirement of each buffalo because of group feeding and management. Least squares mean of profit in first lactation, average profit per day of first calving interval, profit in herd life and average profit per day of herd life were 1992.02±370.79, 5.43±0.08, 8698.62±946.49 and 6.98±0.75 rupees, respectively. Profit per unit of investment in the first lactation, profit per unit of investment in herd life, cost per unit of production in the first lactation and cost per unit of production in herd life were 1.06±0.01, 1.04±0.01, 0.98±0.01 and 0.97±0.01 rupees, respectively.
