EFFECT OF SUPPLEMENTATION WITH GRADED LEVELS OF FABA BEAN HULL, MAIZE GRAIN, AND WHEAT BRAN MIXTURE ON FEED INTAKE, DIGESTIBILITY AND GROWTH PERFORMANCE OF BONGA LAMB

Abstract:

A study was conducted to evaluate supplementation effect of graded levels of faba bean hull (FBH), maize grain (MG) and wheat bran (WB) mixture on feed intake, digestibility and growth performance of Bonga lamb fed a basal diet of natural pasture hay (NPH). Twenty yearling male lambs with an initial body weight of 21.55 kg ± 2.41 (Mean ± SD)” were blocked into five based on their initial body weight and animals within a block were randomly assigned to each treatment. Treatments were ad libitum NPH alone (T1) or supplemented with a ratio of 1:1:2 concentrate mixtures of FBH, MG and WB and animals were offered 150gm (T2), 250gm (T3), and 350 gm (T4) of the concentrate mixture. The feeding and digestibility trials were conducted for 90 and 7 days, respectively. The total DM and OM intake of nutrients were in the order of T1T4>T2). Therefore, it could be concluded that supplementation with FBH, MG, and WB at a ratio of 1:1:2 could be an xvii alternative supplementation strategy to a basal diet of natural pasture hay. For optimal performance and partial budget analysis results CM of 250gm/lamb/day is recommended.
