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 Farklı Aydınlatma Süreleri?ni?n Sülünleri?n (P.colchicus) Bazı Veri?mleri?

The daily light period was increased from 11 h light (L) 14 h darkness (D) initially to 16 h L 8h D in group 1. Birds were exposed to 16 h L 8hD and 8 h L 8h D: 8h L periods in groups 2 and 3 respectively. Following the onset of stimulatory light, the first egg was obtained in 23 and 22 days in groups 1.2 and 3 respectively Egg production periods of pheasants were determined as 138 and 136 days in groups 1.2 and 3. Egg yields of pheasants in groups were found as 40.28, 56.57 and 67.68 egg/pheasant respectively (P < 0.05) Average values of hatchability fertility and hatchability of fertil eggs were determined as 39.48, 48.40 and 54.09 < (P < 0.05) ; 62 17 68 15 and 70.47% (P < 0.05) 63.50, 71.01 and 76.76 % (P < 0.05) in groups respectively.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 Kangal Irkı Türk Çoban Köpekleri?nde Büyüme, Bazı Vücut Ölçüleri? ve Döl Veri?m Özelli?kleri?ni?n Beli?rlenmesi?(Selçuk Üniversitesi, 2000) Tepeli, C.; Çetin, O.This study has been carried out to determine reproductive performance in Kangal Bred of Turkish Shepherd Dogs under feeding and management of Research Farm at Selçuk University Faculty of Veterinary Science Reproductive traits were examined using records of 57 Kangal Shepherd Bitches.

Archaeological data and autosomal single nucleotide polymorphism data have instead suggested that dogs originate from Europe and/or South West Asia but, because these datasets lack data from ASY, evidence pointing to ASY may have been overlooked. Analyses of additional markers for global datasets, including ASY, are therefore necessary to test if mtDNA phylogeography reflects the actual dog history and not merely stochastic events or selection. Here, we analyse 14 437 bp of Y-chromosome DNA sequence in 151 dogs sampled worldwide. We found 28 haplotypes distributed in five haplogroups. Two haplogroups were universally shared and included three haplotypes carried by 46% of all dogs, but two other haplogroups were primarily restricted to East Asia. Highest genetic diversity and virtually complete phylogenetic coverage was found within ASY. The 151 dogs were estimated to originate from 13-24 wolf founders, but there was no indication of post-domestication dog-wolf hybridisations. Thus, Y-chromosome and mtDNA data give strikingly similar pictures of dog phylogeography, most importantly that roughly 50% of the gene pools are shared universally but only ASY has nearly the full range of genetic diversity, such that the gene pools in all other regions may derive from ASY. This corroborates that ASY was the principal, and possibly sole region of wolf domestication, that a large number of wolves were domesticated, and that subsequent dog-wolf hybridisation contributed modestly to the dog gene pool.
