    Effect of Ronoxyme hiphos® supplementation on nutrient digestibility and blood parameters of grower rabbits fed sunflower seed meal-based diets

    sunflower seed meal (SFSM) supplemented with enzyme on nutrient digestibility and blood parameters using 72 growing rabbits. Nine diets namely T1 to T9 were compounded to be isocaloric (2500 kcal/kg, ME) and isonitrogenous (15%) with treatments T1, T2 and T3 having 0% inclusion rate of SFS meal and 0PPM, 150PPM and 250PPM of the enzyme supplementation. Treatments T4 to T6 and T7 to T9 had 10 and 20% levels of SFS meal inclusion rate respectively but maintaining same levels of enzyme supplementation as in T1 to T3. This arrangement translated to T1, T4 and T7 serving as the control diets for T2 and T3, T5 and T6 and T8 to T9, respectively. The rabbits were allotted to the three levels of SFS meal (0,10 and 20%) and three levels of enzyme supplementation (0,150, and 250PPM) in a 3x3 factorial arrangement of a completely randomized design (CRD) to produce nine treatment diets. The treatments were replicated four times. Crude fibre, neutral detergent fibre, acid detergent fibre and cellulose were significantly (P<0.05) higher in rabbit fed 20% (84.58%, 72.24%, 67.16% and 64.27%) SFS diet than 0% (64.20%, 66.68%, 59.40% and 57.81%) and 10% (76.88%, 70.63%, 64.04% and 61.90%) respectively. Enzyme supplementation significantly (P<0.05) improved RBC, the values increased from 5.23 x1012/l for non-enzyme supplementation to 5.38 -5.73 x1012/l. Red blood cell and was significantly (P<0.05) lower in rabbits fed T4 diet than the other groups. Similarly, haemoglobin (11.42 vs. 11.37 and 12.01 g/dl), cholesterol (3.83 vs. 4.33 and 4.31mmol/l) and triglyceride (0.95 vs. 1.16 and 1.03mmol/l) were improved (P<0.05) as the level of enzyme supplementation increased in the diets. In view of the significant improvement in nutrient digestibility and some of the blood parameters recorded, rabbit farmers can use the 150 PPM of the enzyme in SFS meal based diets without affecting the nutrient digestibility and health of the rabbits
