EFFECT OF RONOXYME HiPhos® SUPPLEMENTATION ON BLOOD PARAMETERS OF GROWER RABBITS FED SUNFLOWER SEED MEAL-BASED DIETS

Résumé

A 42 day experiment was conducted to evaluate the response of grower rabbits fed cooked sunflower seed meal (SFSM) supplemented with enzyme on blood parameters using 72 growing rabbits. Nine diets namely T1,T2, T3, T4, T5, T6,  T7, T8 and T9 were compounded to be isocaloric (2500 kcal/kg, ME) and isonitrogenous (15%) having treatments T1, T2 and T3with 0% inclusion rate of SFS meal and 0, 150 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 randomized and allotted to the 9 treatments and each treatment was replicated 4 times giving rise to a 3x3 factorial arrangement fitted into CRD. The results show that 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. 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 some of the blood parameters recorded, rabbit farmers can use the 150 PPM of the enzyme in SFS meal based diets without affecting the health of the rabbits.
