In order to investigate the effects of using live, autolyzed yeast and their combination on performance, and intestinal histology in Japanese quail, 360 of one-day-old chicks were used. Birds were randomly divided into 4 experimental groups in a completely randomized design with 6 replicates. The experimental groups included the control group: fed with basal diet without additives, the second group: fed with basal diet containing 0.4% live yeast, the third group: fed with basal diet containing 0.4% autolyzed yeast and the fourth group: fed with basal diet containing 0.2% live yeast and 0.2% autolyzed yeast. The results showed that the addition of autolyzed yeast caused the greatest increase in body weight gain compared to the control and their mixture in the whole period of experiment (P<0.05). The weight of thigh and pancreas as well as the length of duodenum increased significantly in birds fed with autolyzed yeast compared to live yeast and their mixture (P<0.05). The highest height of duodenal villi was observed in birds fed with autolyzed yeast and live yeast compared to the control treatment and their mixture. Birds fed with autolyzed yeast showed a significant decrease in E. coli bacteria and an increase in Lactobacillus bacteria (P<0.05). The results showed that the use of autolyzed yeast as well as live yeast can be useful in feeding Japanese quails due to improving performance, increasing the height of duodenal villi, reducing the microbial population of E. coli and increasing the cecal population of Lactobacillus.

In order to investigate the effect of vitamin E and vitamin E nanoliposomes on the expression of the STAR gene in testis and TSPO gene in the ovary of Japanese quail, an experiment using 864 pieces of quail for 10 weeks in a completely randomized design with six treatments, six replications and 24 Breeding quail (16 females and eight males) was performed in each replication. The treatments were fed diets containing different levels of vitamin E (25, 50 and 100 IU per kg of diet) and vitamin E nanoliposomes (25, 50 and 100 IU per kg of diet). The results of this study showed that the effect of the experimental treatments on the expression of TSPO gene in the ovary and STAR gene in the testis was significant (P<0.05). The addition of 50 IU of vitamin E significantly increased TSPO gene expression in the ovary compared to the control treatment (P<0.05). The results also showed that the level of 25 IU nanoliposome of vitamin E increased the expression of TSPO gene in the ovary, which was not significantly different from the control treatment. The use of vitamin E and vitamin E nanoliposome levels significantly decreased the expression of STAR gene in the testis of Japanese quail (P<0.05). According to the results of this study, the addition of 25 IU vitamin E nanoliposomes as well as 50 and 100 IU levels of vitamin E has a significant effect on the expression of TSPO gene in the ovary, which is one of the genes affecting fertility and reproduction.

The effect of Betaplus probiotic levels in the diet on growth performance and histomorphometry of Japanese quail jejunum was investigated by using 288 broiler chicks with six treatments of four replications and 12 birds per each in a completely randomized design from one to 42 days of age. Treatments included: control group (without additives); three diets containing levels of 0.5, 1 and 1.5 g/kg of Betaplus probiotic; diet with deficient in protein, and diet with deficient in protein and contained 1 g/kg of Betaplus. Feed intake, body weight and increase body weight were measured weekly and conversion factor was calculated. At 42 days of age, two birds were randomly selected from each replicate and the traits related to carcass dissection were assessed. For histomorphometrical evaluation of the intestine, the jejunum samples were collected. The utility of betaplus probiotic at level 1 g/kg improved food intake, weight gain, conversion factor and some histomorphometrical parameters of jejunum (p <0.05), In birds were feed with level of 1.5 g/kg Betaplus, the villi thickness and crypt diameter and number of the goblet cells were decreased (p <0.05). According to the results, the use of Betaplus probiotic at level 1 g/kg in the diet improves the growth performance and histological parameters of the jejunum in Japanese quail.

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.

The aim of this study was to examine the effects of Artemisia annua L. essential oil (AAEO) and probiotic (Lactobacillus acidophilus) on egg and carcass quality of laying Japanese quails. A total of 180 46-d-old female Japanese quail were randomly allocated to 4 dietary treatments in a completely randomized design with five replicates and nine birds per each. The experimental diets were: 1) basal diet as control group (without additive), 2) basal diet plus oxytetracycline (200 mg/kg), 3) basal diet plus AAEO (250 mg/kg) and 4) basal diet plus probiotic (4 CFU Lactobacillus acidophilus per kg diet). Results showed that the use of probiotic caused to an increase in the cumulative egg weight and daily egg mass, when compared with control and AAEO treatments (P<0.05). In comparison to control group, supplementing the basal diet with AAEO resulted in decreases on MDA level of egg yolk (P<0.05) and liver weight (P=0.06). In addition, the F3 and F2 follicles weights were increased when the basal diet supplemented with each of the feed additives (P <0.05). It can be concluded that, Lactobacillus acidophilus can be used as an alternative to antibiotics for increasing the egg production, and AAEO can be used to produce healthy products in feeding laying Japanese quails.

The aim of this study was to fit the best model for describing the egg production for Japanese quails at thirteen week of age. For this purpose, the daily egg production recordson 314 quails were used for the different models including nonlinear logistic, incomplete gamma, McNally, Lekhorst, Narushin -Takma 2, McMillan and Nelder by R software. The best model was selected by some statics such as Mean square error (MSE), Akaike information criterion (AIC), Bayesian information criterion (BIC). The results showed that Narushin Takma 2 (minimum MSE, AIC and BIC) and Compartmental I Functions (maximum MSE, AIC and BIC) were the best and worst function to describe the egg production, respectively. The highest correlation (0.953) between predicted and actual values for the number of egg were obtained by Narushin -Takma 2 model. The results of the model comparisons and correlations indicate that Narushin - Takma 2 function describes Short- term egg production in quail better than other functions studied in this research and this function could be considered in a short- term prediction of the reproductive potential Japanese quail in breeding goals

This study was conducted to investigate the effect of dietary supplemented with zinc oxide (0, 40, 80, 120 and 160 mg /kg of diet) and vitamin E (Vit E; α-tocopherol acetate; 0 and 40 IU/kg of diet) on fertility and hatchability of Japanese quails, and growth performance and immune response of their progenies. A total of 960 Japanese quails (Coturnix coturnix japonica) 70 d of age were housed in cages and randomly allocated to 10 treatments with 4 replicates of 24 birds in each (sixteen females and eight males). Dietary supplemented zinc and Vit E significantly increased hatchability (P≤0.05). There was a significant effect of Vit E on breeder quails fertility, while zinc supplementation was reduced embryonic mortality at the second stage (10-16 day) (P≤0.05). Supplemental zinc significantly improved feed conversion ratio of offspring in the first three weeks of age, while added Vit E improved feed conversion ratio only in the first week of offspring growth (P≤0.05). Dietary supplementation of Japanese quail’s ration with zinc and Vit E increased immune response of offspring, and enriched Zn content of tibia bone of offspring increased with zinc supplementation. In conclusion, supplementing breeder Japanese quails ration with zinc and Vit E improved hatchability and growth performance and immune response of offspring.

Effect of probiotic, prebiotic and synbiotic in protein-deficient diets on performance and intestinal histomorphometry were investigated in a 2 × 4 factorial experiment. The treatments were arranged in two levels of protein (recommended and 10 percent less than requirements), and four types of additives (without additives, probiotics Gallipro, prebiotic Technomos and a mixture of them) in a completely randomized design with eight treatments and four replicates and 25 birds per each. Birds fed on low protein diet had more feed intake and feed conversion ratio (P<0.05). Feed conversion ratio of birds fed on additives (probiotics, Probiotic and synbiotic) diets was lower than of others (P<0.05). The Relative weight of cecea in birds fed on diets containing low protein was higher than of others (P<0.05). An increase in crypt depth of duodenum and a reduction in villi length in jejenum and villi length: crypt depth ratio in deudenum and jejenum were observed by feeding protein dificeint diets (P<0.05). Villi length in the duodenum of birds fed on additive-less diet were lower than of birds fed diets containing prebiotic or mixture of probiotic and prebiotic (P<0.05). Villi length: crypt depth ratio in jejenum of birds fed on diets containing recommended protein and mixture of probiotic and prebiotic were higher than of others (P<0.05). Villi length in ileum were increased by adding the mixture of probiotic and prebiotic to the diet (P<0.05). Villi thickness in the ileum of birds that were received synbiotic was lower than of birds that fed on diets containing prebiotics (P<0.05). It could be concluded that using of probiotic, prebiotic and their mixtre in protein deficient diets, improve the feed conversion ratio in Japanese quail by improving intestinal histomorphometric parameters.
