| Abstract |
Thirty growing Rahmany male lambs (5-6 months old and weighed in average 28.9 ± 0.9 Kg) were used in growth trial for 120 days and eighteen adult male sheep (weighed in average 60 ± 3 Kg) were used in digestion trials, to evaluate using of dried orange pulp (DOP) as alternative energy source in growing lambs rations contained different protein sources with and without yeast. Lambs in growth trial, depending on its live body weight, were divided into six feeding groups (5 head each). Three animals from the eighteen adult sheep in digestibility trial were randomly assigned to fed one of six experimental rations. The first three rations contained soybean meal (SBM) as protein source and either corn grains, (R1), 50% com grains plus 50% DOP (R2) or 50% com grains plus 50% DOP plus yeast, 3 g/h/d., (R3), while the other three rations contained corn gluten meal (CGM) as protein source with the same previous energy sources and yeast supplementation in the same sequence R4, R5 and R6. The results showed that all of the experimental rations were almost similar in their chemical composition. Data of nutrients digestibility, nutritive value and average daily gain showed that there were insignificant (P<0.05) differences between lambs fed R2 and R3 compared with those fed R1, while lambs fed R5 and R6 recorded best values for the previous parameters compared with those fed R4. On the other hand, all rations contained DOP, regardless protein source, recorded the best values of microbial protein synthesis and the lowest values of pathogenic bacteria and the best feed conversion, but it recorded insignificant differences in blood parameters compared with 100 % com rations. In the same time, R2 ration recorded the lowest cost (Feed cost / Kg gain, L.E.) compared with the other rations. It could be concluded that corn grains could be replaced by 50 % DOP as alternative energy source in growing lambs rations contained soybean meal as protein source to reduce the feed cost without negative effect on animal performance and health.
Keywords: Dried orange pulp, corn grains, soybean meal, corn gluten meal, yeast, growing lambs.
