    This research was conducted to determine effects of chitosan oligosaccharides (COS) addition to quail diets on growth, carcass traits, liver and intestinal histology, and intestinal microflora. Two hundred forty Japanese quail chicks were distributed among three treatments groups, with four replicates. A group was fed with a basal starter diet for 1-21th and a grower diet for 22-42th days (Control). The experimental groups were fed the same diets, in addition to 75 mg/kg (Trial I) or 150 mg/kg (Trial II) of COS. The final live weights of the quails in the Control and Trial I groups were higher than in the Trial II group. There were no differences among the groups in gain, feed intake, feed conversion, and carcass traits. Steatosis in the Trial II group was less than in the Control and Trial I groups. Crypt depth and villus length were higher in the Trial II group than in the other groups. The number of bacteria and yeast in the intestine were lower in the Trial I and II groups than in the Control group. In conclusion, the addition of 75 mg/ kg of COS had no adverse effect on the tested parameters, and it increased the crypt depth, villus length, and beneficially on intestinal microflora.

    This study was conducted to determine effects of black cumin seeds or black cumin oil addition to quail rations on growth performance, carcass traits and some blood parameters. Totally 180 daily Japanese quail chicks were used. Chicks allocated four main groups each containing 45 chicks, and each main group divided into three subgroups each containing 15 chicks. A group was fed with basal starter diet for 1-21th days and grower diet for 22-35th days (Control). Other groups were fed same diets but their diet added by 0.1% oxytetracycline (Positive control: PC), 1% black cumin seed (BCS) or 0.1% black cumin oil (BCO). At last of study 15 chicks from each main group were slaughtered for determination of carcass traits and blood serum parameters. Final average live weight of quails in PC and BCS groups were significantly higher than C group. There were no differences on live weight gain, feed consumption and feed conversion ratio among the groups on basis of whole study period. Carcass weight was lower in C group than the other groups, while there were no differences on carcass yield, leg, breast and wing ratio among the groups. Serum cholesterol concentration in BCO group was significantly lower than C group but there were no differences on Ca, P, VLDL, HDL, LDL, ALT, ALP, albumin, globulin, total protein concentrations among the groups. In conclusion, it was established that, as being in antibiotic added groups, addition of 1% black cumin seed to quail diet enhanced live weight, and 0.1% black cumin oil had showed hypocholesterolemic affect.
