Effect of biological treatments for wheat straw on performance of small ruminants
Abstract: This study consisted of two major experiments. In first trial twelve adult Ossimi rams were divided into four similar groups and used to carry out four metabolic trials three animals for each group) the first (T 1) was the control group fed hay and concentrate feed mixture (CFM) in T2, T3 and T4 (25, 50 and 75%) of CFM protein was replaced by wheat straw treated with fungus, respectively. Treatment of wheat straw with fungus increased protein content from 4.10 to 10.94 % and decreased dry matter, crude fiber, NDF, ADF, ADL, hemicellulose and cellulose content. DMI increased (P<0.05) in control and T3 than T2 and T4. CF, ADF, NDF, ADL, hemicellulose and cellulose. digestibilities were higher (P<0.05) in control group than all treated groups, while divisibility of crude protein and rumen liquor parameters were higher (P<0.05) in . control and T3 than T2 and T 4. In the second experiment 24 Rahmani lambs with 21.0 kg initial body weight and four months old were divided into four similar groups and fed according to the feeding regime in first experiment. Average daily body weight gain was 186.6, 165.7, 162.8 and 39.5 g for Tl, T2, T3 and T4 respectively. Feed conversion was 7.35, 9.15, 9.69 and 11.84 DM/kg gain for TI, T2, T3 and T4, respectively. Economical efficiency was 177.5, 177.9, 211.5 and 211.8 for T1, T2, T3 and T4, respectively.
