EFFECTS OF DIETS CONTAINING DEFATTED SESAME MEAL WITH PHYTASE ENZYME SUPPLEMENTATION ON HAEMATOLOGICAL INDICES AND SERUM METABOLITES OF BROILER CHICKENS.

Abstract

Adequacy of diets in livestock production reflects in the blood parameters. Serum and haematological parameters are used to evaluate nutrient composition of diet and health status of animal in which the diet is being tested. One hundred and eighty broiler chicks of Marshall Strain were used to evaluate the effects of phytase enzyme supplementation on the utilization of diet containing defatted sesame meal (DSM) by broiler chickens. Six dietary treatments in a 2×3 factorial experimental arrangement of 0.25g/100kg phytase supplementation at 3 level of DSM inclusion (0, 50 and 100 %). Each treatment had 30 birds subdivided into three replicates of 10 birds each. The result obtained indicated White blood cells, creatine and Uric acid were significantly (P<0.05) affected by sesame inclusion and enzyme supplementation interaction. Birds fed enzyme supplemented diets containing 50% sesame meal recorded the highest (P < 0.05) WBC value 35.02 x 1012/l. Birds fed 100% sesame meal (T6) showed least (P < 0.05) value 0.80 g/dl for creatinine. PCV, HB, RBC, total protein and albumin were not significantly influence by sesame inclusion and enzyme supplementation interaction. Defatted sesame meal with Phytase enzyme supplementation could replace soybean up to 100% in broiler chickens diets without hazard effect on the health status.
