Öğe Comparison of hatchability and some egg quality characteristics in spotted and unspotted partridge (Alectoris chukar) eggs(OXFORD UNIV PRESS, 2014) Caglayan, Tamer; Kirikci, Kemal; Aygun, AliThe current research was conducted to determine the comparison of hatchability and some egg quality characteristics in spotted and unspotted partridge (Alectoris chukar) eggs. The research was carried out on 51 male and 102 female chukar partridges (Alectoris chukar) aged 50 wk, which were raised at the Research and Application Farm of the Faculty of Veterinary Medicine of Selcuk University. In total, 244 spotted and 261 unspotted eggs were used in the research. The hatching eggs were stored at 75% RH and 13 degrees C for 14 d. Thirty spotted and 30 unspotted eggs laid on the same day were used for the evaluation of egg quality characteristics. Egg weight, chick weight, egg weight loss during the hatching period, shape index, hatchability, and some egg quality characteristics were evaluated at the end of the research. Spotted eggs exhibited a higher fertility and hatchability, as well as a lower percentage egg weight loss and embryonic mortality when compared with unspotted eggs. No significant differences were observed between spotted and unspotted eggs for egg weight, chick weight, shape index, specific gravity, albumen height, Haugh unit, yolk color green-red chromaticity (a*), albumen pH, and yolk pH. Spotted eggs had higher eggshell color a*, eggshell color blue-yellow chromaticity (b*), and eggshell strength, as well as a lower eggshell color light-dark chromaticity (L*), yolk color L*, and yolk color b* scores when compared with unspotted eggs. It was demonstrated that spots on the eggshells of chukar partridges (Alectoris chukar) improved their hatchability by affecting various quality characteristics of their eggs. It was concluded that spotted eggs are more suitable for hatching.Öğe Correlations Among Chick Hatching Weight, Egg Weight and Egg Weight Loss During Preincubation Storage Period in Japanese Quail (Coturnix coturnix japonica)(MEDWELL ONLINE, 2009) Dere, Suleyman; Caglayan, Tamer; Garip, Mustafa; Inal, SerefThis study was carried out to investigate, the relationships among chick hatching weight, egg weight and egg weight loss during preincubation storage period in Japanese quail. Correlation coefficients between chick hatching weight and egg weight, egg weight loss during 4 days preincubation period were determined as 0.47 (p<0.01) and 0.36 (p<0.01). Highly positive correlations among egg weight loss groups were determined (P<0.01).Öğe Effect of egg weight on chick weight, egg weight loss and hatchability in rock partridges (A-graeca)(TAYLOR & FRANCIS LTD, 2009) Caglayan, Tamer; Garip, Mustafa; Kirikci, Kemal; Gunlu, AytekinThis study was conducted to determine the effect of egg weight on chick weight, egg weight loss and hatchability in partridges. Eggs (847) obtained from rock partridges (44-46 weeks ages) were classified according to their weights as <18 g, 18.00-18.99 g, 19.00-19.99 g, 20.00-20.99 g, 21.00-21.99 g, 22.00-22.99 g and >= 23 g and incubated. A positive, powerful and important correlation (0.46 and 0.82 values) between egg weight and egg weight loss and chick weight in different groups was determined (P<0.001) in the study. The differences between hatchability and fertility in the egg groups were significant (P<0.05), but no differences were detected between hatchability of fertile eggs and embryonic mortalities. In conclusion, smaller and bigger eggs of partridges had low fertility while hatchability was disproportionately reduced in eggs that had lost less mass during incubation.Öğe The Effects of Parent Age, Egg Weight, Storage Length and Temperature on Fertility and Hatchability of Japanese Quail (Coturnix coturnix japonica) Eggs(MEDWELL ONLINE, 2009) Dere, Suleyman; Inal, Seref; Caglayan, Tamer; Garip, Mustafa; Tilki, MuammerThis study was carried out to investigate the effects of egg weight, storage temperature of hatching eggs, parent age and storage length during preincubation period on fertility and hatchability traits in Japanese quail. Totally 5015 eggs data obtained from Japanese quail, in factorial design trial (2x2x4x10), was analysed by General Linear Method (GLM) by using 4 way analysis of variance (10-11 and 14-15 degrees C egg storage temperature, 3 and 6 months of parentage; 10, 10-11, 11-12, >12 g egg weights and 0-9 days egg storage length factors). Inspecting GLM results, differences among fertility averages was statistically significant for egg weight (p = 0.0001), egg storage temperature (p = 0.007) and storage length (p = 0.018) factors and was not statistically significant for parent age factor. Differences among hatchability averages was statistically significant for egg weight (p = 0.005), egg storage temperature (p = 0.0001) and was not statistically significant for storage length and parent age factors.Öğe External and internal egg quality characteristics in Japanese quails of different plumage color lines(WFL PUBL, 2011) Yilmaz, Alper; Tepeli, Cafer; Caglayan, TamerThe present study was conducted to determine the external and internal egg quality characteristics in Japanese quails (Coturnix coturnix japonica) of different plumage color lines. A total of 150 eggs obtained from Japanese quails of different plumage color lines at 20 weeks of age were used in the study. The eggs were randomly gathered from same age quails with brown, gray and white plumages. The eggs were examined for external and internal quality characteristics. Concerning the external quality characteristics, there were statistical differences regarding shape index (%) and shell ratio (%) among the different plumage color lines (P<0.01, P<0.05). Of the internal quality characteristics, the differences among plumage color lines in yolk weight(g), albumen weight (g), yolk ratio (%), albumen ratio (%), yolk/albumen ratio (%), albumen index (%) and haugh units were statistically significant (P<0.01). It was also found that there were statistically significant phenotypic correlations with respect to some egg quality traits in the different plumage color lines. According to the findings of the study, the fact that the haugh unit observed in the quail group with brown plumage was higher compared to the other plumage color lines brings into mind the idea that it could be more convenient to offer the eggs in the brown group for consumption as human food. In addition, knowing the significant differences among the different plumage color lines in different quality characteristics will be useful in assisting prospective studies on quail lines.Öğe Growth and some period yield characteristics of Denizli x Leghorn crosses (F?)(Selçuk Üniversitesi, 2011) Ozsensoy, Yusuf; Garip, Mustafa; Nizamlioglu, Mehmet; Kurar, Ercan; Yilmaz, Alper; Caglayan, Tamer; Dere, Suleyman; Bulut, Zafer; Kurtoglu, VarolAmaç: Bu araştırmada, Denizli x Leghorn F, ve F, populasyonlarının çıkım ağırlığı, büyüme ve verim dönemine ait canlı ağırlıkları, yumurta ağırlığı ve özgül ağırlıklarının belirlenmesi amaçlamıştır. Gereç ve Yöntem: Temel populasyonda 10 Denizli horozu ve 30 Leghorn tavuk kullanılmıştır. İlk generasyonda (F?), 15 erkek, 68 dişi elde edilmiştir. İkinci generasyonda (F?) ise 475 erkek ve 451 dişi üzerinde 32 haftaya kadar canlı ağırlık ve yumurta verimleri incelenmiştir. Bulgular: F? populasyonunda dişiler yumurtaya girdikten sonra 180 günlük dönemde, yumurta sayıları ve yüzdeleri 99.61 adet ve %56.21 olarak bulundu. Çıkım ağırlıkları F, ve F, populasyonlarında sırası ile 40.94 ve 30.80 g olarak bulundu. Büyüme döneminde her iki generasyonda canlı ağırlıklar arasında önemli farklılıklar tespit edildi (p<0.001). Ayrıca ikinci generasyonda 32. hafta sonunda canlı ağırlıklar dişilerde 1814.60 g, erkeklerde ise 1900.00 g olarak ölçüldü (p<0.001). Ayni generasyonda yumurta ağırlığı ve özgül ağırlık değeri 47.81 g ve 1.08 olarak hesaplandı. Öneri: Yerli gen kaynağımız olan Denizli ırkının melezleme çalışmalarında kullanılabileceği, geliştirilmiş yumurtacı ve etçi ırklarla melezlemelerin ve bu verim yönleri bakımın dan Denizli ırkının daha detaylı çalışmalarla incelenmesine ihtiyaç olduğu sonucuna varıldı.Öğe Improving mobile sheep walk-over weighing system designed for quick, easy and accurate evaluation of herds' status in field(CURRENT BIOLOGY LTD, 2013) Polat, Esad Sami; Caglayan, Tamer; Garip, Mustafa; Coskun, Behic[Abstract not Available]Öğe Investigation of genetic diversity and paternity in kangal white karaman rams using microsatellite markers(KAFKAS UNIV, VETERINER FAKULTESI DERGISI, 2012) Kurar, Ercan; Bulut, Zafer; Caglayan, Tamer; Garip, Mustafa; Yilmaz, Alper; Nizamlioglu, MehmetThe objectives of this study were to estimate genetic diversity and test possibility of conducting paternity testing at the DNA level as part of a breeding project of Kangal White Karaman sheep. As a pilot study, blood samples were collected from 13 rams that were used for breeding purposes in two different flocks in which level of inbreeding is proposed to be high. A total of 20 microsatellite markers were used to amplify genomic DNA by polymerase chain reaction (PCR). The resulting PCR products were separated by capillary electrophoresis and allele genotypes were determined. A total of 99 different alleles were determined ranging from 1 to 8 at each locus. The observed (Ho) and expected heterozygosities (He) values were ranged from 0.000 to 0.923 and from 0.000 to 0.871, respectively. Polymorphism information content (PIC) values were between 0.000 and 0.818. Total power of exclusion (PE) value was calculated as 0.999975 for twenty loci. Our results suggested that a panel, including the most informative twelve loci provides a total PE value of 0.999828, can be useful for parentage testing in Kangal White Karaman sheep.
