| Abstract |
Five experimental rations were evaluated in this study of which 33% and 66% of concentrate feed mixture (CFM) was replaced by yellow corn (YCG)or crushed yellow corn ear (UCE) and their effect on lambs performance were also studied this rations contained different levels of CFM(3% , 2% or 1%) UCG (2%, or 1% ). UCE (2%, or1%) of body weight)and rice straw ad lib forty Barki male lambs of average 25.85-Kg body weight were divided into five groups and assigned at random to the experimental rations for 140 days. Five metabolism trials were conducted during weeks 11 and 12.
Results obtained show that replacement of CFM with YCG or YCE increased digestibility coefficients, nutritive values, nitrogen balance, concentrations of plasma TP, albumin, glucose, and improved daily gain. It also gave the best feed conversion, economical efficiency and the lowest feed cost/Kg weight gain.
It is concluded that using local raw materials in formulating rations may reduce costs without adverse effects on animal performance.
