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 Denizli X leghorn F2 popülasyonunda canlı ağırlık ve yumurta verimini etkileyen kromozom bölgelerinin tanımlanması(2013) Bulut, Zafer; Kurar, Ercan; Özsensoy, Yusuf; Nizamlıoğlu, Mehmet; Garip, Mustafa; Yılmaz, Alper; Çağlayan, Tamer; Dere, Suleyman; Kurtoglu, Varol; Dogan, MugeAmaç: Bu çalışmanın amacı; Denizli X Leghorn F2 populasyonunda yumurta verimi ve farklı dönemlerde canlı agırlığı kontrol eden kromozom bölgelerinin tanımlanmasıdır. Gereç ve Yöntem: Denizli ve Leghorn ırkları kullanılarak F2 düzeyinde deneysel bir populasyon oluşturuldu ve verim kayıtları alındı. Kromozom tarama çalışmaları için kantitatif özellik lokusları (QTL) gen haritalama analizlerine uygun 113 mikrosatellit markörü F0, F1 ve F2 bireylerde Polimeraz Zincir Reaksiyonu (PZR) ile yükseltgendi. Bulgular: Bu çalışmanın sonucunda farklı dönemlerde canlı ağırlık ile ilişkili QTL bölgeleri tavuk 1. kromozom çiftinde (GGA1), GGA2 ve GGA4 üzerinde tespit edildi. Yumurta verimi üzerine etkili iki farklı QTL bölgesinin varlığı, GGA8 ve cinsiyet kromozomu (GGAZ) üzerinde bulundu. GGA2, GGA4 ve GGAZ üzerinde bulunan üç farklı QTL ile yumurta ağırlığı arasında bir ilişki tespit edildi. Öneri: QTL bölgelerinin yeni markörler ile daraltılması ve bölgesel klonlama çalışmaları ile bu verim özelliklerini kontrol eden genlerin tespit edilmesi gerekmektedir.Öğe The Effect of Storage Period and Temperature on Weight Loss in Quail Eggs and the Hatching Weight of Quail Chicks(MEDWELL ONLINE, 2011) Garip, Mustafa; Dere, SuleymanThe present study was aimed at the determination of the effects of storage period and temperature on weight loss in quail eggs, hatchability results and hatching weight of quail chicks. Total 6,000 eggs obtained from a quail flock composed of 250 male and 750 female animals which were of the same age, provided with the same feed, exposed to the same management conditions and raised in cages and 2004 quail chicks which hatched from these eggs constituted the material of the study. Eggs of hatching quality, weighing 12-15 g were allocated to 3 groups and were stored at temperature of 11 degrees C (10-12), 21 degrees C (20-22) and 27 degrees C (26-28), respectively. Each of the 3 temperature groups were divided into 4 sub-groups such that they were stored at the indicated temperature for a period of 1, 5, 10 and 15 days, respectively thus, resulting in a total number of 12 groups. Throughout the storage period, all eggs were kept in 3 storage compartments which had the same features and of which the humidity was adjusted to 75 +/- 5%. Throughout the storage period, eggs were neither subjected to pre-storage incubation nor were their position altered. Throughout the trial period, the humidity rate of the storage compartments was reduced at the following rates for the sub-groups which were stored for periods of 1, 5, 10 and 15 days, respectively; in the group subjected to a storage temperature of 11 degrees C 0.2, 0.6, 1.3 and 1.8%, in the group exposed to a storage temperature of 21 degrees C 0.6, 1.5, 3.1 and 5.3% and in the group stored at a temperature of 27 degrees C 1.1, 2.0, 3.7 and 6.10%, respectively. In the same sub-groups, the hatching weight of the chicks were as follows; in the group subjected to a storage temperature of 11 degrees C 9.47, 9.18, 9.50 and 9.13 g, in the group exposed to a storage temperature of 21 degrees C 9.38, 9.42, 9.41 and 9.30 g and finally, in. the group stored at a temperature of 27 degrees C 9.67, 9.49 and 9.071 g for the 1st three sub-groups, respectively. The sub-group of eggs which was stored at 27 degrees C for 15 days did not hatch. The differences between the calculated percentages were statistically significant (p<0.05). When evaluated together with hatchability results and embryonic death, it was determined that egg weight losses above a rate of 3% affected hatching weight and hatchability adversely. Moreover, in the group of eggs determined to have suffered a weight loss percentage of 6.1% no hatching was observed.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.
