Abstract:
Background and Objective: Protein considered the second main nutrient in diet formulation for all types of animals after energy. Present study aimed to evaluate the effect of different treatments on the nutritive value of Jatropha meal (JM) by in vitro and in vivo trials as protein source in sheep diet. Materials and Methods: Chemical composition, in vitro digestibility, gas production and phorbol esters (PE) were recorded for physically, chemically and biologically treated Jatropha meal. In vivo digestibility was measured by using 24 Barki rams randomly assigned into 4 nutritional groups (6 animals/treatment) as follow: 1) control ration and in 2, 3 and 4 groups cotton seed meal replaced with 30, 45 and 60% heated Jatropha meal (HJM). Results: The various treatments raised DM (Dry matter), CP (Crude protein), NFE (Nitrogen free extract) and ash, whereas reduced OM (Organic matter), CF (Crude fiber) and EE (Ether extract) content in JM, the results of in vitro dry matter disappearance (IVDMD) have a significant height (p<0.01) for physical followed by the chemical and biological treatments. Otherwise high significant results (p<0.01) for gas production for different treatments was observed. The different treatments decreased the concentration of PE in JM than untreated. Conclusion: It can be concluded that all treatments especially heat enhanced chemical composition, IVDMD of JM and gas production. Feeding values were better with the ratio 30 and 45%.
