| Abstract | ||||
| Thirty Barki lambs of 6 months old and weighing 27.34 ± 2.14 kg LBW were used to investigate the effect of whole toasted soybean seed (SBS) and raw sunflower seed (SFS) levels in complete ration of growing male on their productive performance. Animals were divided into five groups (6 lambs each). Ration were basically formed of: yellow corn grain, soybean meal, wheat bran, peanut tops, molasses, common salt and limestone which mixed in different rations according to rate of adding oil seeds to the mixtures. The concentrations 0 f different ingredients are illustrated in table (1). The experimental groups were allotted randomly to five tested complete rations: control (R1): without full fat seeds (CR), (R2) & (R3): containing 90 and 80% CR + 10% and 20% SBS, and (R4) and (R5): 90 and 80% CR + 10% and 20% SBS, respectively. The feeding trail was extending to 112 days. Feed intake, digestibility coefficients, nutritive values, nitrogen utilization, daily gain, liver and kidney functions, feed and economical efficiency were determined. Apparent digestibility coefficients of CP and EE (P<0.05) increased with increasing SBS and SFS levels in rations. On the contrary, the CF decreased (P<0.05) with increasing SBS and SFS levels in rations. The TON, OCP DE and ME of SBS and SFS rations were higher (P<0.05) than those of the control ration were. Daily OMI expressed as kg/hid or OM/kg WO.75 was significantly (P<0.05) higher by lambs fed the control ration than those offered other tested rations. Lambs received SBS recorded significantly (P<0.05) higher average daily gain (AOG) than those received SFS rations. The (AOG) values were (199.86 & 221.85) vs. (207.50 & 198.70) g/day for 10 and 20% SBS and SFS, respectively, while lambs of the control recorded 179.50 g/day. Serum TP and Urea-N significantly (P<0.05) increased with including full fat seeds in lamb diets, while serum creatinine showed significant (P<0.05) decrease. Lambs fed full fat seeds had lower (P<0.05) levels of serum cholesterol and triglycerides than those fed the control ration. Feed and economical efficiency were markedly better with the 10 and 20% SBS and 10% SFS rations than other rations. It is suggested that including full-fat soybean seeds up to 20% and 10% sunflower seeds in complete mixture rations, can efficiently improve the feeding value, digestibility coefficients and feed and economical efficiencies of growing lambs. | ||||
