Öğe Effect of dietary hazelnut meal supplementation on the meat composition of quails(SCIENTIFIC TECHNICAL RESEARCH COUNCIL TURKEY-TUBITAK, 2005) Yalcin, S; Oguz, F; Yalcin, SThis experiment was conducted to study the effects of dietary hazelnut meal supplementation on the meat composition of quails. A total of 312 one-clay-old Japanese quail chicks (Coturnix coturnix japonica) were divided into 6 equal groups. Six different levels of hazelnut meal (0%, 10%, 15%, 20%, 25% and 30%) were included in their diets. At the end of the 5-week experiment, 12 quails (6 male and 6 female) were slaughtered from each group at random. The levels of dry matter, protein, fat, ash and some mineral elements of the meat were determined. The values of protein, ash, energy, calcium, phosphorus, iron and zinc in the meat were not influenced by dietary treatment or sex. Significant differences (P < 0.05) in dry matter content of the meat between the control group and the groups fed 15%, 20% and 25% hazelnut meal and in fat content between the control group and the group fed 20% hazelnut meal were detected. However, when analysis of male and female carcass meat was performed separately. there were no significant differences in dry matter or fat content. It was concluded that the supplementation of hazelnut meal up to 30% to quail diets did not have any adverse effect on the meat composition.Öğe Effects of supplementary iodine on the performance and egg traits of laying hens(TAYLOR & FRANCIS LTD, 2004) Yalcin, S; Kahraman, Z; Yalcin, S; Yalcin, SS; Dedeoglu, HE1. This experiment was carried out to determine the effects of dietary iodine supplementation on the performance and egg traits of laying hens. A total of 600 SHSY type brown layers aged 21 weeks of age were chosen at random from a large flock. They were randomly distributed into 30 pens at 20 hens per pen. Each treatment comprised 6 replicates of 20 layers in groups of 5 birds. The diets were supplemented with 0, 3, 6, 12 and 24 mg/kg iodine as calcium iodate. The experimental period lasted 30 weeks. 2. There were no significant differences among the groups in body weight, food consumption, egg production, food consumption per kg eggs, eggshell index, eggshell breaking strength, shell thickness or egg yolk index. 3. Supplementation of the diet with 12 mg/kg iodine increased food consumption per dozen eggs compared to the groups fed on diets supplemented with 0 and 6 mg/kg iodine. 4. Egg weight was less in groups fed on diets supplemented with 12 and 24 mg/kg iodine than in the group receiving no iodine supplementation. 5. Iodine supplementation to provide 12 and 24 mg/kg reduced egg albumen index and egg Haugh units. 6. There were no significant differences among the groups in egg cholesterol and egg yolk cholesterol contents. 7. The iodine concentrations in egg yolk, egg albumen and whole egg increased with increased iodine supplementation. 8. As a result, the 3 and 6 mg/kg iodine supplementation of diet could be used to enrich the eggs with iodine without any adverse effect on performance and egg traits.Öğe Fecal coliform contamination of beef carcasses during the slaughtering process(FOOD NUTRITION PRESS INC, 2001) Yalcin, S; Nizamlioglu, M; Gurbuz, UThe purpose of this study was to determine the fecal coliform counts of beef carcasses during different stages in the slaughter process. A total of nine carcasses were selected at random in the abattoir. The samples were taken by excision from three different sites; rump, brisket and shoulder. The samples were collected from the same carcasses at four different stages of processing; after dressing, after evisceration, after washing and after chilling for 24 h in a chilling room. The processing steps did not increase the fecal coliform counts on the rump samples. There were no significant differences in the samples of rump and shoulder among different processing steps. The contamination level of the brisket after washing was significantly higher than other processing steps. Brisket and shoulder parts are critical points for microbiological sampling as these sites showed higher microbial counts after chilling steps. The data obtained have relevance for the planning of washing methods for the production of clean and safe carcasses.Öğe Microbiological conditions of sheep carcasses during the slaughtering process(FOOD NUTRITION PRESS INC, 2004) Yalcin, S; Nizamlioglu, M; Gurbuz, UThis study was undertaken to determine the microbiological quality of sheep carcasses during different stages in the slaughtering process. A total of eleven carcasses were selected at random in an abattoir. The samples were taken by excision from four different sites; leg, brisket, shoulder and neck. The samples were collected from the same carcasses at four different stages in the slaughtering process; after dressing, after evisceration, after washing and chilling. The aerobic mesophilic bacteria, coliforms and Enterobacteriaceae recovered from each sample were enumerated. Chilling reduced the aerobic mesophilic and coliform counts of carcasses, significantly. Levels of carcass microbial load after chilling were 1.69, 0.11 and 0.11 log cfu/cm(2) for aerobic mesophilic counts, coliform counts and Enterobacteriaceae counts, respectively. According to data obtained in the present study, chilling of carcasses was the most important step in improving the hygienic quality of carcasses. Processing stages changed significantly both aerobic mesophilic and coliform counts of neck, therefore, among different sites of carcass, neck should be the only critical site for microbiological sampling for sheep carcasses.Öğe Nosocomial oral myiasis by Sarcophaga sp in Turkey(YONSEI UNIV COLLEGE MEDICINE, 2005) Yazar, S; Dik, B; Yalcin, S; Demirtas, F; Yaman, O; Ozturk, M; Sahin, IWe present a case of oral myiasis in a 15-year-old boy with tuberculosis meningitis. The diagnosis was based on the visual presence of wriggling larvae about 1 cm in size and on the microscopic features of the maggots, especially those relating to stigmatic structures. The larvae were identified as third-stage larvae of Sarcophaga sp.Öğe The use of different levels of common vetch seed (Vicia sativa L.) in diets for fattening rabbits(ELSEVIER SCIENCE BV, 2003) Yalcin, S; Tuncer, I; Yalcin, S; Onbasilar, EEAn experiment was conducted to study the effects of various levels of common vetch seed (Vicia sativa L.) in the diet on the growth performance and some carcass characteristics of rabbits. In the experiment a total of 96 weaned New Zealand White rabbits aged 35 days and weighing on average 800 g were equally divided into four groups of 24 (six replicates of two male and two female rabbits each). Four levels (0, 10, 20 or 30%) of common vetch seed were included in isonitrogenous and isocaloric diets. The experimental period lasted 6 weeks. The average values of total live weight gain for control group. the first, second and third treatment groups were 950, 945, 826 and 848 g (P > 0.05), feed consumption values per kg live weight gain were 3.65, 3.63, 3.91 and 3.92 kg (P > 0.05), respectively. At the end of the experiment, there were no significant differences among the groups in live weight, live weight gain, feed consumption, feed efficiency, carcass yield and the percentages of liver, kidney, heart and lung. However the inclusion of 20 and 30% vetch seed in the diets decreased the weight gain by 13.04 and 10.76% and increased the feed consumption per kg weight gain by 7.12 and 7.40% compared to control group, respectively. The percentage values of head, skin and limbs, forelegs, hindlegs, breast and fibs, loin and abdominal wall were also not affected by these levels of vetch seed. It is concluded that common vetch seed can be given to the rabbits at the levels up to 10% of the diet without adverse effects on growth performance and carcass characteristics.

A total of 280 Japanese quails aged 10 weeks, divided into one control group and three treatment groups, were used. The diets of the first, second and third treatment groups were supplemented with 100 mg L-carnitine/kg, 1.5 g humate (Farmagulator (R) Dry Plus)/kg and 100 mg L-camitine + 1.5 g humate/kg, respectively. The experimental period lasted 16 weeks. The addition of L-camitine and sodium humate alone or in combination did not significantly affect body weight, feed consumption, egg production, feed conversion ratio, mortality, egg-shell thickness, egg yolk index and the percentages of egg-shell, albumen and yolk. Egg weight increased (P < 0.001) with L-camitine supplementation. The values of egg albumen height (P < 0.05), egg albumen index (P < 0.01) and egg Haugh unit (P < 0.05) were increased with humate supplementation. Egg cholesterol content and blood serum parameters were not affected by the supplementation of L-camitine with or without humate. The results in this study demonstrated that L-carnitine supplementation increased egg weight while humate addition increased egg albumen index and egg Haugh unit of laying quails. However, the combined administration of L-camitine and humate did not have any significant effects on the parameters measured.
