| Abstract | ||
| The objective of this work was to study cultivation sesbania and its mixtures with sorghum or millet in reclaimed sandy soil, then utilization the green forages in feeding of growing lambs for 16 weeks in two stages (The 1st cut was fed in the 1st stage through the first 8 weeks and 2nd cut was fed in the 2nd stage through the last 8 weeks).Twenty four Ossimi lambs averaged 22.5 kg body weight were divided into four groups (6 in each) to evaluate the following rations: Ration A (control): 100% from requirements of CP according to NRC(1985) from Concentrate Feed Mixture (CFM) + Rice straw ad lib., Ration B: 50% from requirements of CP according to NRC from CFM + Sesbania ad lib., Ration C: 50% from requirements of CP according to NRC from CFM + Sesbania-Sorghum mixture (1:1) ad lib. and Ration D: 50% from requirements of CP according to NRC from CFM + Sesbania-Millet mixture (1:1) ad lib. Digestibility trials were conducted to evaluate the experimental rations using 12 rams (3 in each). The rumen parameters were measured and forage yield was determined. Results showed that DM and CF% were lower and CP% was higher in Sesbania than Sorghum, Millet, Sesbania-Sorghum mixture and Sesbania-Millet mixture. The differences among all rations in digestion coefficients of DM, OM, CP, NFE and TDN% of tested rations were not significant. The ruminal parameters explained that the pH of control was significantly higher than other groups at all times in 2nd stage, while the differences among other groups were not significant. The differences of ammonia-N at 2hrs after feeding were not significant among groups, while ammonia-N of control was significantly higher than other groups at 4hrs, and the differences among other groups were not significant at the same time. The differences number of TVFA's among groups were not significant in 1st stage. The differences of protozoa at 4 hrs post feeding were not significant among all groups. The differences of microbial protein were not significant among all groups in the 1st stage. The highest cost value of feed consumption was recorded with control. The daily body gain(DBG) were 156.1, 150.3, 154 and 154.8 gm/h/d for lamb groups which fed rations A, B, C and D respectively and the differences of DBG among four groups were not significant. The best feed conversion and economical efficiency were recorded with ration D. The green forage yield of Sesbania pure, Sesbania-Sorghum mixture and Sesbania-Millet mixture were 10.85, 15.31 and 15.30 ton/feddan, dry yield were 2.22, 3.32 and 3.34 ton/feddan, and crude protein yield were 403, 451 and 478kg/feddan, respectively. | ||
