The experiment was carried out to investigate the effect of tryptophan, melatonin and dimethylglycine on the growth performance and meat quality of Japanese quails fed diets contaminated with aflatoxin B1 toxin. In this experiment, 680 Japanese quail from 7 to 35 days of age were allotted to 17 treatments and 4 replicates (10 birds per replication), and trial performed using a central composite design. The performance of birds was calculated on a weekly basis and at the end of the experiment; and the amount of malondialdehyde in meat was determined. Results showed that tryptophan increase weight gain and melatonin had an increased effect on feed intake (P < 0.05). The effect of tryptophan and as well as the interaction of tryptophan and dimethylglycine reduced the amount of malondialdehyde in meat (P < 0.05). The results obtained from this research state that dietary supplementation with tryptophan and methyl group donors have good antioxidant capacity to reduce aflatoxin B1 poisoning on growth performance and malondialdehyde content of meat, and the use of these supplements in the diet of Japanese quails seems desirable.

In order to evaluate the effects of different levels of mineral salts, chelates and nano iron resources supplementation to diet on performance, tissue iron reserves and meat quality of Japanese quails, an experiment was carried out using 400 Japanese quails in a completely randomized design with 10 experimental treatments and 4 replicates. The experimental treatments consisted of one basal diet without iron supplement (control) and basal diets supplemented with levels of 60, 90 and 120 mg/kg of sulfate, chelate and nano iron. Birds fed 120 mg chelate of iron had more weight gain than control, 60 and 120 mg sulfate (P<0.05). Nutrition of 90 and 120 mg Nano iron improved feed conversion ratio compared to controls, sulfate and 60 mg chelate iron. Birds fed with diet containing 90 and 120 mg chelate and 120 mg nano iron had more iron accumulation in breast meat than sulfate and control groups (P<0.05). The group of 120 mg chelate iron had higher water holding capacity than control, 60 mg and 90 mg sulfate, 60 mg chelate and 90 mg nano iron treatments, and lower amount of malondialdehyde than control and 60 mg sulfate iron groups. The group of 120 mg nano iron had higher iron in the liver and blood serum, and lower cooking loss compared to the control (P<0.05). Effect of experimental treatments on feed cost were not significant. In this study, various forms and levels of iron had a variable effect on the studied parameters.

In order to study the effect of different levels of dietary electrolyte balance (DEB) and calcium on performance, bone composition and carcass characteristics of Japanese quail, a total of 720 quail chicks were used in a 3×3 factorial arrangement with completely randomized design including three levels of DEB (150, 250 and 350 mEq/kg) and three levels of dietary calcium (0.4, 0.8, and 1.6%) in 9 treatments, 5 replications and 16 birds per each replicate from 14 to 35 days of age. The results showed that the birds fed diet containing 0.4% calcium and 250 mEq/kg DEB had the highest feed intake (P<0.05). Experimental treatments had no effect on feed conversion ratio. At both 0.4 and 0.8% of dietary calcium level, the highest bone calcium content was observed at 150 mEq/kg DEB (P<0.05). The minimum kidney weight was observed in treatment containing 1.6% calcium and 150 mEg/kg DEB and the maximum thigh and breast relative weights were observed in treatment containing 0.8% calcium and 150 mEq/kg DEB (P<0.05). In conclusion, the interaction of dietary calcium and DEB could be considered as an important limitation in the feed formulation of growing Japanese quail.

This experiment was conducted to assess the effect of safflower meal (SFM) containing microbial and enzyme supplementations on performance, meat quality and humoral immunity of Japanese quail. A total of 300 seven-days-old Japanese quails were assigned in a completely randomized design to five treatments, four replications and 15 chicks in each replication. The experimental treatments included 1) a corn and soybean meal based diet (control) 2) diet containing 20% SFM 3) diet containing 20% Fermented SFM 4) diet containing 20% SFM + Calsporin® probiotic at a rate of 50 mg/kg feed and 5) diet containing 20% SFM+ Endo-Power® enzyme to the amount of 125 mg/kg feed. The results of this study showed that the use of fermented SFM, Calsporin® probiotic and enzyme treatments improved weight gain and feed intake of chicks when compared to control group (P<0.05). The feed conversion ratio for the chicks in control group and quails receiving diets containing fermented SFM and SFM+ Endo-Power® enzyme was lower than that of other experimental groups (P<0.05). Birds fed with SFM had lower meat cooking loss (P<0.05). The meat water holding capacity and also antibody titer against sheep red blood cell (SRBC) were higher in treatment receiving fermented SFM when compared to control group (P<0.05). According to the positive effects of nutrition with fermented SFM and containing probiotic and enzyme supplements on performance, meat quality and immunity system of Japanese quail, this accessible and inexpensive source of protein could be used in quail diet.

This experiment was conducted to evaluate the effects of dietary Salvia mirzayanii supplementation on performance, carcass characteristics, internal organs and cecal microbial population in broilers. A total of 200, one-day-old broiler chicks (Ross 308) were fed five experimental diets containing different levels of S. mirzayanii (zero, 0.25, 0.50, 0.75 and one percent of diet) until 42 days of age. From 1-21 days of age, birds fed one percent S. mirzayanii) had lower body weight gain and feed intake and higher feed conversion ratio (P<0.05). Regarding 22-42 days of age and whole of experiment (1-42), feed conversion ratio in birds fed diet containing 0.5 percent S. mirzayanii significantly (P<0.05) decreased compared with control group. Relative carcass and breast muscle weights of birds fed one percent S. mirzayanii were lower than other groups (P<0.05). Using S. mirzayanii at the levels of 0.25 and 0.5 percent significantly increased cecal lactic acid bacterial population (P<0.05). Feeding with the levels higher than 0.5 percent S. mirzayanii decreased cecal coliforms compared with control group (P<0.05). Based on results of this experiment, using 0.5 percent S. mirzayanii leaf powder in diet of broilers would improve cecal microbial population as well as growth performance.

Effect of adding Hibiscus sabdariffa (HS) in diet on performance and immune response of broilers was examined during aflatoxicosis using a total of 192 day-old Ross 308 male chicks in a completely randomized design with four treatments, four replicates and 12 chicks per each replicate. Treatments were include: 1. negative control (without additives), 2. positive control (2.5 mg aflatoxin B1/kg), 3. diet containing Hibiscus sabdariffa(10 g HS/kg) and 4. diet contaminated with aflatoxin and containing Hibiscus sabdariffa (2.5 mg AFB1/kg + 10 g HS/kg). Effect of treatments on feed intake was not significant. Weight gain of chicks in positive control treatment was lower than those birds in other treatments (P<0.001). These birds had higher feed conversion ratio (P<0.001). Antibody titer against Newcastle disease virus and sheep red blood cell in birds fed positive control and containing Hibiscus sabdariffa diets were lower and higher than those birds in negative control group, respectively (P<0.001). The least skin thickness after challenging with dinitrochlorobenzene (DNCB) was observed in birds fed positive control diet (P<0.001). Relative weight of bursa of Fabricius in chicks fed positive control and Hibiscus sabdariffa diets was lower and higher than that of negative control group, respectively (P<0.001). Based on results of this experiment, supplementation of Hibiscus sabdariffa to aflatoxin contaminated diets could ameliorate the effects of toxin on growth performance and immunity response of broilers.

Effect of Protexin to diminish negative consequences of feeding aflatoxin B1 (AFB1) contaminated diet on performance, immune response, meat quality and ileal microbial flora were examined using 320 seven-day-old Japanese quails fed four treatments [control diet (without additives), diet containing 2.5 mg AFB1/kg, diet containing 150 mg Protexin/kg, diet containing 2.5 mg AFB1/kg+150 mg Protexin/kg] with four replicates and 20 birds each in a completely randomized design. Feed intake of birds fed probiotic diet was higher than those birds in control group (P<0.05). Weight gain in birds fed aflatoxin contaminated diet was lower than birds in other treatments (P<0.05). Humoral immunity response in quails related to aflatoxin and probiotic groups was lower and higher than control group, respectively (P<0.05). Skin thickness increase after 48h challenging with dinitrochlorobenzene (DNCB) in birds fed aflatoxin contaminated diet was lower than the other groups (P<0.05). Concentration of malondialdehyde (after freezing meat for 30 days) in the meat of aflatoxin fed birds was higher than the other birds (P<0.05). Population of E. coli and lactic acid bacteria in birds fed protexin or aflatoxin+protexin was lower and higher than the two other groups, respectively (P<0.05). Based on the result of this research, dietary inclusion of protexin probiotics into aflatoxin contaminated diet could improve immunity response and intestinal microbial population in Japanese quails.
