Effect of use different levels of black and green combined cumin powder on performance, some blood parameters and intestinal morphology of Japanese quails

This research was carried out in order to investigate the use of cumin and black cumin powder mixture on performance, some biochemical parameters of serum and morphology of small intestine tissue in male Japanese quails. In this experiment, 160 pieces of Japanese male quail were used in a completely randomized balanced design with four treatments, four replications and 10 pieces of quail in each replication from the age of 7 to 35 days. The supplement of mixed green and black cumin powder was used at four levels of zero (control), 0.5, 1 and 1.5% in the diet. The results showed that the use of a mixture of cumin and black cumin powder had no statistically significant difference on the amount of feed consumption, weight gain and feed conversion ratio compared to the control treatment. Also, the weight of the carcass, breast, thigh, pre-stomach, gizzard, intestine and heart was not significantly affected by the treatments. The amount of blood serum cholesterol decreased significantly (P≤0.05). Serum glucose significantly increased in the treatment containing 0.5% of the mixture of green and black cumin powder (P≤0.05). Total protein significantly increased in the treatment of 1.5% green and black zebrafish mixture (P≤0.05). Serum triglyceride decreased significantly (P≤0.05) in treatments using black and green cumin powder (P≤0.05). The amount of serum uric acid in the diet with 1% mixed powder of green and black cumin was significantly (P≤0.05) higher than other treatments. There was no significant difference between the length, width, height of the villi and the mucous layer of the small intestine in the treatments using green and black cumin powder and the control treatment. In general, the results of this research showed that the use of cumin and black cumin powder in male Japanese quails is recommended.
