Effects of different forms of white lupin (Lupinus albus) grain supplementation on feed intake, digestibility, growth performance and carcass characteristics of Washera sheep fed Rhodes grass (Chloris gayana) hay-based diets

Protein is the major limiting nutrient in feeding ruminants especially in dryland areas. Thus, looking for locally available protein sources such as white lupin (Lupinus albus) grain is commendable. The objective of this experiment was to determine effects of supplementation of different forms of wh...

Description
Summary:Protein is the major limiting nutrient in feeding ruminants especially in dryland areas. Thus, looking for locally available protein sources such as white lupin (Lupinus albus) grain is commendable. The objective of this experiment was to determine effects of supplementation of different forms of white lupin grain (WLG) on feed and nutrient intake, digestibility, growth and carcass characteristics. Twenty-five yearling male Washera sheep with initial body weight (BW) of 16.26 ± 1.41 kg (mean ± SD) were used. Animals were blocked into five based on their initial BW and were randomly assigned to one of the following five dietary treatments: Rhodes grass (Chloris gayana) hay (RGH) alone (T₁) or supplemented with 300 g (on dry matter (DM) basis) raw WLG (T₂) or raw soaked and dehulled WLG (T₃) or roasted WLG (T₄) or raw soaked WLG (T₅). Supplementation with WLG significantly improved total DM and nutrient intake (P
