Öğe Effects of dietary L-carnitine supplementation on growth performance and some biochemical parameters in Japanese quails (Coturnix coturnix japonica)(Ecole Nationale Veterinaire Toulouse, 2008) Yalcin, S.; Ozsoy, B.; Cengiz, O.; Bulbul, T.This experiment was carried out to determine the effects of different contents of L-carnitine added to quail diets on some growth characteristics and blood biochemical parameters. For that, 345 one week old Japanese quail chickens (Coturnix coturnix japonica) were divided into 5 equal groups according to the L carnitine contents added to the diet for 4 weeks (0 mg/kg of diet in the control group, 50, 100, 150 and 200 mg/kg in the treatment groups 1, 2, 3 and 4, respectively). Body weights, body weight gains, food intake and food efficiency were determined weekly. At the 4(th) week of treatment, carcass traits and blood biochemical parameters (serum total protein, cholesterol and triglyceride concentrations as well as serum ALP, AST and ALT activities) were analyzed from 12 randomly selected males in each group. With the highest L carnitine dosage, body weights significantly increased at the 2(nd) week of treatment and the cumulative body weight gains on the whole period were significantly higher than in the other groups. In parallel, the total food intake tended to slightly decrease whereas food efficiency and weights and yields of carcasses tended to be improved in the group treatment 4 but not significantly. By contrast, lower dosages of L carnitine failed to induce changes in weight gain, food consumption or in carcass traits. Furthermore, biochemical parameters were not affected by L carnitine supplementation whatever the dose used. These results suggest that higher dosages of L carnitine (above 200 mg/kg) would be necessary for improving lipid metabolism and growth in quails.Öğe Effects of dietary live yeast culture on fattening performance on some blood and rumen fluid parameters in goats(Ecole Nationale Veterinaire Toulouse, 2013) Ozsoy, B.; Yalcin, S.; Erdogan, Z.; Cantekin, Z.; Aksu, T.The objectives of this study were to evaluate the effects of live yeast culture supplementation as a natural feed additive on fattening performance, some blood and rumen fluid parameters in male goats. Totally 48 hybride male goat kids (Saanen x Sami breeds) were divided into one control and three treatment groups each containing 12 kids. Concentrates of groups were formulated as isonitrogenic and isocaloric. Live yeast culture (RumiSacc, Integro Food Industry and Trade Co., Istanbul, Turkey; Live yeast cell: 1.4 x 10(8) cfu per gram) was included in the concentrates at 0 (CON), 1.5 (YC15), 3.0 (YC30) and 4.5% (YC45) on fed basis, respectively. Concentrates were given ad libitum and 100 g per day per animal of lentil straw was given as roughage. Dietary yeast culture at the level of 4.5% increased total weight gain (+15.5% regarding control group). Rumen ammonia-N level was increased with 3 and 4.5% of live yeast culture (+30.9 and +30.5% regarding control group). Ruminal total and individual VFA and blood plasma levels of total protein, albumin, urea nitrogen, total cholesterol, triglyceride and the activities of alanine amino transferase, aspartate amino transferase and gamma-glutamyl transferase were not affected from the dietary treatments. Coliform bacteria count in ruminal fluid and faeces was decreased with yeast culture supplementation. It is concluded that live yeast culture can be included in male goat diets at the level of 4.5% with positively affecting performance.Öğe Effects of the usage of dried brewing yeast in the diets on the performance, egg traits and blood parameters in quails(Cambridge Univ Press, 2008) Yalcin, S.; Erol, H.; Oezsoy, B.; Onbasilar, I.; Yalcin, S.This experiment was carried out to determine the effects of the usage of dried brewing yeast in quail diets on laying performance, egg traits and blood parameters. A total of 240 Japanese quails (Coturnix coturnix japonica) aged 10 weeks were randomly allocated into one control group and three treatment groups. Each group was divided into five replicates as subgroups, comprising 12 quails each. Dried brewing yeast (Saccharomyces cerevisiae) was used at the levels of 1.5%, 3.0% and 4.5% in the diets of the first, second and third treatment groups, respectively. Soyabean meal was replaced with dried brewing yeast. The diets were formulated to be isocaloric and isonitrogenous. The experimental period lasted 18 weeks. Dietary treatments did not significantly affect body weight, daily feed intake, daily protein intake, egg production, egg weight, feed efficiency, mortality, egg shell thickness, egg albumen index, egg yolk index, egg Haugh unit, the percentages of egg shell albumen and yolk, excreta moisture and small intestinal pH. Inclusion of 3% and 4.5% dried brewing yeast in diets reduced egg yolk cholesterol concentration as mg per yolk and mg per g yolk (P < 0.01). Blood serum cholesterol of groups fed diets with dried brewing yeast was significantly lower (P < 0.01) than that of the control group. Feeding diets containing 3.0% and 4.5% dried brewing yeast resulted in significant increases (P < 0.01) in blood serum levels of total protein, alanine aminotransferase at the end of the experiment. Blood serum levels of uric acid, triglyceride, aspartate aminotransterase and alkaline phosphatase were not affected by dietary dried brewing yeast. It is concluded that dried brewing yeast can be used up to 4.5% in the diets of laying quails without adverse effects on the measured parameters.Öğe First report of Olive latent virus 1 from olive trees in Turkey(Springer, 2007) Serce, C. Ulubas; Yalcin, S.; Gazel, M.; Caglayn, K.; Faggioli, F.[Abstract Not Available]Öğe Yeast Culture Supplementation to Laying Hen Diets Containing Soybean Meal or Sunflower Seed Meal and Its Effect on Performance, Egg Quality Traits, and Blood Chemistry(Poultry Science Assoc Inc, 2008) Yalcin, S.; Oezsoy, B.; Erol, H.; Yalcin, S.This study was designed to investigate the effects of yeast culture supplementation to laying hen diets containing 2 oilseed meals on performance, egg traits, and some blood parameters. A total of 180 Lohmann Brown laying hens 21 wk of age were allocated to 4 dietary treatments and fed for 16 wk. Two different basal diets were prepared; one contained soybean meal and the other contained sunflower seed meal. Both of the basal diets were supplemented with 0 and 2 g/kg commercial yeast culture product (Saccharomyces cerevisiae). Yeast culture supplementation to diets containing either oilseed meal did not significantly affect feed intake, hen-day egg production, feed efficiency, interior and exterior egg quality characteristics, serum levels of total protein, triglyceride, cholesterol, alanine amino transferase, aspartate amino transferase, and alkaline phosphatase. Body weight gain (P < 0.05), egg weight (P < 0.001), and serum uric acid (P < 0.05) were increased with yeast culture supplementation. The reduction in egg yolk cholesterol was significant (P < 0.001) in the groups fed yeast-supplemented diets. The results in this study demonstrated that yeast culture supplementation to the diets containing soybean meal or sunflower seed meal increased egg weight and decreased egg yolk cholesterol without affecting performance and egg traits, but serum uric acid concentration was increased.
