Nutritional and economical impact of using dried orange pulp as energy source in growing lambs rations [electronic resource].

Includes references.

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 weigh, 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 ofsix experimental rations. The first three rations contained soybean meal (SBM) as protein source and either corn grains., (R1), 50% corn grains plus 50% DOP (R2) or 50% corn grains plus 50% DOP plus yeast, 3g/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.
