Abstract

This study has been conducted to investigate the effects of exposing pheasants to different light periods on their egg production characteristics and hatching traits. The daily light period was increased from 11 h light (L): 14 h darkness (D) initially to 16 h L: 8 h D in group 1. Birds were exposed to 16 h L: 8 h D and 8h L:8hD: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.

Özet

Bu araştırma farklı sürelerde yapılan aydınlatmanın sülünlerde yumurta verimi ve bazı kuluçka özellikleri üzerine etkilerini belirlemek amacıyla yapılmıştır. Araştırmada 1. Gruba (kontrol grubu) 11 saat Aydınlık (A): 14 saat Karanlık (K) olacak şekilde ışık verilmiş ve ışığın süresi haftada 1 saat artırılarak 16 saat A: 8 saat K olacak şekilde sabitlenmiştir. ikinci gruptaki sülünlere 16 saat A: 8 saat K; 3. Gruptaki sülünlere ise 8 saat A: 8 saat K: 8 saat A olacak şekilde bir aydınlatma programı uygulanmıştır, ilk yumurta 1. ve 2. (16A:8K) grupta aydınlatmaya başlandıktan 23, 3. (8A:8K:8A) grupta ise 22 gün sonra elde edilmiştir. Yumurtlama periyodu süresi kontrol ve 2. grupta 138, 3. grupta ise 136 gün olarak gerçekleşmiştir. Bu süre içerisinde gruplarda sülün başına elde edilen yumurta verimi sırasıyla 40.28, 56.57 ve 67.68 adet olarak tespit edilmiştir (P<0.05). Gruplarda kuluçka randımanı, döllülük oranı ve çıkım oranı sırasıyla % 28.81, 38.94 ve 49.0 (P<0.05); % 39.48, 48.40 ve 54.09 (P<0.05);.% 62.17, 68.15 ve 70.47 (P<0.05); % 63.50, 71.01 ve 76.76 (P<0.05) olarak bulunmuştur
