Evaluation of Oat (Avena sativa) Genotypes for Agronomic Parameters, Silage Quality, and Its Feeding Value on the Performance of Bonga Sheep in South Ethiopia

Abstract

Ethiopia is recognized for its substantial livestock population; however, the productivity of this sector remains low. This is largely attributed to several factors, with feed quality and quantity being significant contributors to the issue. The challenges include inadequate access to quality feed, seasonal variability in feed availability, and high prices of feed ingredients, which collectively hinder effective livestock production. The present study was conducted with the objectives of (1) evaluating eleven oat genotypes in four different environments to identify high-biomass-yield genotypes in selected parts of Ethiopia; (2) exploring the fermentation characteristics and nutritional value of A. sativa genotypes ensiled sole or in combination with P. purpureum 16791; and (3)evaluating the effect of feeding different Avena sativa (AS) varieties in the form of hay to yearling Bonga sheep on feed intake, weight gain, carcass characteristics and economic feasibility
