| Abstract |
The effect of dietary enzyme (Optizyme) on the performance of Japanese quail hens fed isocaloric and isonitrogenous diets containing 0, 10, 20 and 30% of Nigella seed meal (NSM) as a protein source. A com-soybean meal diet was used as a control diet. Eight groups of birds having 8 replicates consisting of 2 females and 1 male were used, and productive and reproductive traits and egg quality were measured. Hens fed 10% NSM produced significantly more egg than those fed 0, 20 and 30% NSM diets. Shell thickness was also significantly higher in the 10% NSM group. Supplementation of enzyme significantly improved egg production and tended to improve shell thickness when 20% NSM diet was fed, but not when 30% NSM was given. Furthermore, the enzyme significantly improved the fertility rate when fed 20% NSM diet but not in the groups fed 30% NSM diet, From these observations, Japanese quail hens can be fed diet containing 10% NSM. Moreover, this level can be increased to 20% when supplemented with enzyme.
Key words: Japanese quail, laying performance, Nigella meal
