Roasting Technique Nutritional Value Improved Brugmansia Suaveolens Brows Leafe Supplementation on Performance of Yearling Bonga Sheep

Abstract

The experiment was conducted to evaluate the effect of roasting technique nutritional value improved brugmansia suaveolens leafe, concentrate and their mixtures supplementations on intake, body weight gain and carcass parameters of yearling bonga sheep graze basal diet natural pasture grass adlibly, and to assess the economic benefit of the supplementation. The experiment was carried out at Modeyo Bonga sheep multiplication center, Decha woreda, Kafa Zone, Ethiopia using twenty eight yearling male bonga sheep with a mean (±SD) initial body weight of 31.67±1.59 kg.The animals were vaccinated against internal and external parasites, respectively, before the start of the experiment. Experimental sheep were adapted for 15 days to the treatment feeds. The experiment consisted of feeding trial of 90 days. The experiment was laid out in a randomized complete block design (RCBD) with four blocks consisting of seven animals per block based on their initial body weight. Dietary treatments were randomly assigned to one of the four treatment diets within a block. Treatments comprised of grazing natural pasture adlibitum-T1; grazing natural pasture adlibitum supplementation with 5 minute rosted brugmansia suaveolens leafe (RBS, 538gm)-T2; Concentrate composed of: Wheat (354 gm) , fabeaben (77 gm), barley (102 gm) -T3; RBS and concentrate-T4.The amount of supplement offered was 538 g/day on DM basis. There is free access to clean drinking water. Supplementation improved very significantly (p
