Effect of maxigrain ^(®) enzyme supplementation on blood chemistry of growing Japanese quails fed sun-dried yam peel meal based diet

Abstract

28-day study was carried out to evaluate the effect of dietary enzyme (Maxigrain®) supplementation on hematology and serum biochemistry of Japanese quails fed sun dried yam peel meal (YPM) based diets. A total number of 240 healthy Japanese quail chicks of two weeks old were used and randomly distributed to the four dietary treatments with four replicates of 15 birds each in a completely randomized design. Four experimental diets were formulated in which enzyme supplemented yam peel meal (YPM) replaced maize at 0, 25, 50, and 75% as T₁, T₂, T₃ and T₄ respectively. Diet one (T₁) served as the control without YPM and enzyme inclusion while diet 2 to 4 were supplemented with 0.1% of Maxigrain^® enzyme. Blood samples were collected from three birds in each replicate at the end of the study for haematological and serum biochemical evaluations. Results revealed that variation in the dietary treatments had no significant (P<0.05) difference on all haematological and serum biochemistry indices evaluated except for packed cell volume, hemoglobin, total protein and uric acid which were significantly (P>0.05) affected as the inclusion level of enzyme supplemented yam peel meal increased in the diets. Therefore, Japanese quail can tolerate enzyme supplemented yam peel meal at 75% replacement level for maize in their diets without any deleterious effect on their blood profile for healthy production.
