Öğe Effect of clinoptilolite on performance of Japanese quail (Coturnix coturnix japonica) during experimental aflatoxicosis(TAYLOR & FRANCIS LTD, 1999) Parlat, SS; Yildiz, AO; Oguz, H1. Clinoptilolite (CLI, a natural zeolite), incorporated into the diet at 50 g/kg, was evaluated for its ability to reduce the deleterious effects of 2.0 mg total aflatoxin (AF;83.06% AFB(1), 12.98% AFB(2), 2.84% AFG(1) and 1.12% AFG(2))/kg diet on growing Japanese quail chicks from 10 to 45 d of age. A total of 40 Japanese quail chicks were divided into 4 treatment groups (control, AF, CLI, AF plus CLI) each consisting of 10 chicks. The performance of the birds was evaluated. 2. The AF treatment significantly decreased food consumption and body weight gain from the 3rd week onwards. The adverse effect of AF on food conversion ratio was also significant from week 4 of the experiment. 3. The addition of CLI to an AF-containing diet significantly reduced the deleterious effects of AF on food consumption, body weight gain and food conversion ratio. Food consumption was reduced by 14% in quail chicks consuming the AF diet without CLI, but by only 6% for quail chicks consuming the AF plus CLI diet. Similarly, overall body weight gain was reduced by 27% in birds consuming the AF diet without CLI, but by only 8% for birds consuming the AF plus CLI diet. 4. The addition of CLI to the AF-free diet significantly decreased food consumption and body weight gain during week 4, but these parameters were similar to the controls in week 5. No mortality was observed in any of the groups. 5. These results suggest that CLI effectively diminished the detrimental effects of AF on the variables investigated in this study.Öğe Effect of dietary addition of live yeast (Saccharomyces cerevisiae) on some performance parameters of adult Japanese quail (Coturnix coturnix japonica) induced by aflatoxicosis(ECOLE NATIONALE VETERINAIRE TOULOUSE, 2004) Yildiz, AO; Parlat, SS; Yildirim, IThe amelioration of aflatoxicosis in adult Japanese quail was examined by the dietary addition of live yeast (Saccharomyces cerevisiae; SC). Yeast incorporated into the diet at 2 g kg(-1) was evaluated for its ability to reduce the deleterious effects of 5.0 ppm total aflatoxin (82.06 % AFB(1), 12.98 % AFB(2), 2.84 % AFG(1) and 1. 12 % AFG(2)) added to the diet of adult female Japanese quail from 49 days to 84 days of age, Forty, 49-day-old adult female Japanese quail were assigned to a completely randomized design of treatments; control, aflatoxin (AF), Saccharomyces cerevisiae (SC), aflatoxin plus Saccharomyces cerevisiae (AF plus SC) each consisting of 10 quail. The performance parameters of birds, were evaluated. The AF treatment significantly and dramatically decreased body weight gain, food consumption, egg production and egg weight from the first week onwards. Significant adverse effects of AF on food conversion ratio and deaths were noted throughout the experiment. The addition of SC to the AF-containing diet significantly reduced these deleterious effects of AF on body weight gain, food consumption, egg production, egg weight and food conversion ratio. Compared to controls, the cumulative body weight gain was reduced by 39 percent among the quail consuming AF without SC, but increased 65 percent for the birds fed AF plus SC. Interestingly, the single inclusion of SC to the AF-free diet provided significant improvements in all the performance parameters compared to controls.Öğe Effects of dietary mannanoligosaccharide on performance of Japanese quail affected by aflatoxicosis(SOUTH AFRICAN JOURNAL OF ANIMAL SCIENCES, 2004) Oguz, H; Parlat, SSThe potential of the yeast component, mannanoligosaccharide (MOS) to ameliorate the effects of aflatoxicosis was examined in growing Japanese quail. The product was incorporated in the diet at 1 g/kg and was evaluated for its ability to reduce the deleterious effects of 2 mg total aflatoxin (AF; 82.30% AFB(1), 2.06% AFB(2), 7.68% AFG(1) and 7.96% AFG(2))/kg diet on Japanese quail chicks from 10 to 45 days of age. Forty 10-d old Japanese quail chicks were assigned in a 2x2 factorial arrangement of treatments to four groups (Control, AF, MOS, AF plus MOS), each consisting of 10 quails. The addition of AF alone significantly decreased feed consumption and body weight gain from the first week onwards. A significant adverse effect of AF on the feed conversion ratio was also observed from week 4 onwards. The addition of MOS to the AF-containing diet significantly reduced these adverse effects of AF on feed consumption, body weight gain and feed conversion ratio. The cumulative body weight gain was 22.0% lower in the quails consuming a diet containing AF without MOS as compared to the control group. However, it was only 2.3% lower that the control in the birds fed the diet containing the AF plus MOS.Öğe The effects of organic chromium supplementation on production traits and some serum parameters of laying quails(ECOLE NATIONALE VETERINAIRE TOULOUSE, 2004) Yildiz, AO; Parlat, SS; Yazgan, OThis study was conducted to determine the effects of organic Cr supplementation on production traits and some serum parameters of laying quails. Fifty-three-days old laying quails were randomly divided into five groups of 45 birds per group. Corn-soybean meal based basal diet without additional Cr contained 1268.05 ppb Cr. The dietary treatments consisted of the supplementation of the basal diet with 0, 250, 500, 750 and 1000 ppb Cr supplied from Cr picolinate. All birds received feed and water ad libitum. Increasing organic Cr supplementation resulted in an increase egg production and also improved feed conversion ratio (P<0.05). Also egg, yolk and albumen weights increased linearly by dietary organic Cr inclusions (P<0.05), but Cr supplementation did not effect eggshell weight and eggshell thickness. However, serum glucose and cholesterol concentrations decreased, while chromium, insulin and total protein concentrations increased linearly as dietary Cr level increased (P<0.05). These data indicated that organic Cr supplementation increased performance traits, particularly egg production and feed conversion ratio, serum insulin concentrations, egg, yolk and albumen weights of laying quails.Öğe Effects of phytase on the performance and availability of phosphorus in corn-soybean meal diets by young Japanese quails(EUGEN ULMER GMBH CO, 1997) Bahtiyarca, Y; Parlat, SSAn one experiment were conducted to evaluate of the effect of supplementing microbial phytase to corn + soybean meal based diets containing different levels of available phosphorus (AP) on the performance and utilization of phosphorus in young Japanese quail. Nine treatments consisting of three levels of AP (0.25, 0.35, 0.45%) and three levels of phytase (0, 0.05, 0.1%) ill 3x3 factorial arrangement were used with ten quails replications per treatment. The research was terminated on 30(th) days old. Phytase supplementation at 0.1% level of diets containing 0.45 and 0.35% AP were significantly increased body weight (p < 0.05), and decreased feed:gain ratio and also improved tibia ash and breaking strength in comparation with control group fed 0.45% AP without phytase. But differences in groups weren't found to be significant. When the diet with 0.25 AF was supplemented phytase, growth rate of quails were positively effected and the results were found to be similar or slightly high than control group, and also feed : gain ratio were improved but differences in groups didn't significant. Bone ash was decreased with 0.25% AP with 0.1% phytase (p < 0.05) but breaking strength of tibia wasn't significantly effected with phytase.Öğe A method for prediction of individual food intake from group feeding in animal nutrition experiments(EUGEN ULMER GMBH CO, 1998) Parlat, SS; Yildiz, AO1. Individual food intake was predicted from group feeding on quail chicks. 2. Two experiments were carried out as individual and group feeding. 3. The basic data were weekly total food intake and weight gain obtained from group feeding. 4. The correlation between weekly total food intake and weight gain was investigated (P < 0.01). 5. After weekly relative food intake and weight gain were calculated, their regression equation was estimated. 6. Individual food intakes were predicted from weekly total weight gains of birds applied group feeding. 7. The individual food intake data predicted from regression equation were compared with that of obtained from individual feeding experiment. There were no differences in individual food intake. 8. The results concluded that individual food intake could be predicted by proposed methods.
