This study was performed to investigate the effects of egg weight and amount of protoporphyrin and biliverdin in the eggshell on hatchability and embryonic mortality in pheasants. A total of 1908 eggs obtained from 48 weeks old pheasants were used in the study. The eggs were divided into three colour groups (dark brown, light brown and green) and two weight groups (up to 32 g and above 32 g). For the weight groups, there were significant differences in the hatchability of fertile eggs (P<0.01) and late period embryonic mortality (LPEM) (P<0.05). The highest hatchability of fertile eggs and the lowest embryonic mortality were determined in light eggs (≤32 g). In terms of eggshell colour groups, there were significant differences in the hatchability of total eggs (P<0.01); hatchability of fertile eggs (P<0.01); and early (P<0.01), middle (MPEM) (P<0.05) and late period (P<0.05) embryonic mortality. In present study, the highest hatchability and the lowest embryonic mortality rate (except for MPEM) were in the dark brown eggshell group. For all groups, the differences in fertility rate were insignificant (P>0.05). The highest hatching characteristics and the lowest embryonic mortality rates were determined in the dark brown eggs. Based on these results, to achieve higher a hatchability of total eggs, hatchability of fertile eggs and a lower embryonic mortality rate, it may be beneficial selection of dark brown pheasant eggs
Bu araştırma, sülünlerde yumurta ağırlığı ve yumurta kabuğundaki protoporfirin ve biliverdin miktarının kuluçka özellikleri ve embriyonik ölüm üzerine etkisini araştırmak amacıyla yapılmıştır. Araştırmada 48 haftalık sülünlerden elde edilen toplam 1908 yumurta kullanılmıştır. Yumurtalar üç renk grubu (koyu kahve, açık kahve ve yeşil) ve iki ağırlık grubu (≤32 g ve 320.05) bulunmuştur. En yüksek kuluçka performansı, kuluçka oranı ve en düşük embryonik ölüm oranı koyu kahve kabuklu yumurtalarda bulunmuştur. Bu sonuçlara bağlı olarak, daha yüksek bir kuluçka randımanı, çıkım gücü ve daha düşük bir embriyonik ölüm oranı elde etmek için, koyu kahverengi sülün yumurtalarının seçimi yararlı olabilir
