Dietary energy utilization of indigenous sheep fed with complete feed consisting of agricultural and agroindustrial by-products

Abstract

An experiment was carried out to investigate the utilisation of dietary energy of complete feed composed of various agricultural and agro-industrial by-products on indigenous male lambs. Sixteen indigenous sheep (13+1.46 kg of initial body weight, 3-5 m of age) were fed with various agricultural and agro-industrial by-products arranged in a completely randomised design with 4 different ration compositions (R1 = rice straw + soybean meal, R2 = maize straw + soybean sauce industry by product, R3 = peanut hay + coconut cake, and R4 = sugar cane + tofu cake) and 4 replications. Intakes of dry matter (DM), energy, digestible energy (DE), metabolizable energy (ME), and average daily gain (ADG) were measured and analyzed using ANOVA followed by Duncan’s test.. The results showed that there were no significant differences (P>0,05) in all parameters measured. The daily intakes of DM, DE, ME and ADG were 923.59 g, 7.87 MJ, 6.89 MJ and 0.12 kg, respectively. The calculation on DE and ME requirement for 1 kg body weight gain were found to be 65.43 and 57.38 MJ, respectively. It was concluded that the dietary energy utilizations of complete feed consisting of agricultural and agro-industrial by-products on indigenous sheep were not different.
