Öğe Determination of chromosomal regions affecting some production traits in F-2 intercross chickens(WILEY-BLACKWELL, 2009) Bulut, Z.; Kurar, E.; Ozsensoy, Y.; Nizamlioglu, M.; Garip, M.; Yilmaz, A.; Caglayan, T.[Abstract not Available]Öğe Development of Denizli x White Leghorn F-2 population for quantitative trait loci mapping(WILEY-BLACKWELL, 2009) Nizamlioglu, M.; Garip, M.; Yilmaz, A.; Caglayan, T.; Kurar, E.; Bulut, Z.; Kurtoglu, V.[Abstract not Available]Öğe The effects of incubation temperature on the sex of Japanese quail chicks(OXFORD UNIV PRESS, 2011) Yilmaz, A.; Tepeli, C.; Garip, M.; Caglayan, T.The effects of incubation temperature on the sex of Japanese quail chicks were investigated in this study. The study was conducted on Japanese quail. In all, 4500 eggs obtained from 2 generations were used. At the beginning of the study, a new flock was formed from available hatching eggs. Hatching eggs were gathered at 3 different ages (8 to 10 weeks, 16 to 18 weeks and 22 to 24 weeks of age) from the laying period in this flock. These eggs were exposed to 5 different incubation temperatures (36.7, 37.2, 37.7, 38.2, and 38.7 degrees C). The hatching results were evaluated for each group. Chicks obtained from these temperature groups were reared separately to obtain quail for breeding. Eggs for incubation were gathered from these breeding quail when they were between 15 and 18 weeks of age. These eggs were placed in an incubator at a standard (37.7 degrees C) temperature, separated by F-1-generation temperature groups. The chicks in all groups were reared separately, and the sex of the chicks was determined at maturity. Statistical differences (P < 0.05) were found for the sex of the chicks in the third group (22 to 24 weeks) of the F-1 generation, compared with other groups. This result confirmed the hypothesis that different incubation temperatures for the first generation (at the embryo stage) might influence the sex of the next generation of chicks. Further studies are needed to investigate the effects of incubation temperature on chicks from different perspectives.Öğe Effects of zinc deficiency and drought on grain yield of field-grown wheat cultivars in Central Anatolia(WILEY-BLACKWELL, 2007) Bagci, S. A.; Ekiz, H.; Yilmaz, A.; Cakmak, I.Drought stress and zinc (Zn) deficiency are serious abiotic stress factors limiting crop production in Turkey, especially in Central Anatolia. In this study, the effects of Zn deficiency and drought stress on grain yield of 20 wheat cultivars (16 bread wheat, Triticum aestivum; four durum wheat, Triticum durum cultivars) were investigated over 2 years under rainfed and irrigated conditions in Central Anatolia where drought and Zn deficiency cause substantial yield reductions. Plants were treated with (+Zn: 23 kg Zn ha(-1), as ZnSO(4).7H(2)O) and without (-Zn) Zn under rainfed and irrigated conditions. Both Zn deficiency and rainfed treatments resulted in substantial decreases in grain yield. Significant differences were determined between both bread wheat and durum wheat cultivars in terms of drought stress tolerance. Considering drought sensitivity indices over 2 years, the bread wheat cultivars Yayla-305, Gerek-79, Dagdas-94 and Bolal-2973 were found to be more drought-tolerant than the other cultivars under both -Zn and +Zn treatments. Especially the durum wheat cultivars Cakmak 79 and Selcuklu 97 showed much greater drought susceptibility under Zn deficiency, and irrigation alone was not sufficient to obtain satisfying grain yield without Zn application. The results indicate that sensitivity to Zn deficiency stress became more pronounced when plants were drought-stressed. The effect of irrigation on grain yield was maximized when Zn was adequately supplied, leading to the suggestion that efficient water use in Central Anatolia seems to be highly dependent on the Zn nutritional status of plants.Öğe Genetic characterization of Akbas shepherd dogs in Turkey, Uzbekistan and Iran using STR markers(WILEY-BLACKWELL, 2012) Nizamlioglu, M.; Bulut, Z.; Erdogan, M.; Tepeli, C.; Yilmaz, A.; Kurar, E.; Savolainen, P.[Abstract not Available]Öğe Microsatellite analysis of Kangal shepherd dogs in Turkey, Uzbekistan, Ajerbaijan and Iran(WILEY-BLACKWELL, 2012) Bulut, Z.; Tepeli, C.; Nizamlioglu, M.; Kurar, E.; Erdogan, M.; Yilmaz, A.; Savolainen, P.[Abstract not Available]Öğe Serological survey of bovine enterovirus type 1 in different mammalian species in Turkey(WILEY, 2008) Guer, S.; Yapkic, O.; Yilmaz, A.The bovine enterovirus type 1 (BEV-1) infection has a wide range of host Spectrum including humans. In this study, seroprevalence of BEV-1 was investigated in eight mammalian species. Blood serum samples were collected from 244 humans, 1520 cattle, 272 horse, 126 dog, 281 sheep, 477 goat, 18 came] (Camelus dromedarius) and 82 gazelle (Gazella subgutturosa subgutturosa) in different regions of Turkey. Microneutralization tests showed that gazelle and camel did not have any seropositivities, but seropositivities were detected in humans (30.3%), cattle (64.8%), horse (12.8%), dog (3.2%), sheep (32.8%) and goat (27.6%).
