Effect of Egg Weight on Egg Traits and Hatching Performance of Turkey (Meleagris gallopavo) Eggs
The study was conducted to determine the effects of turkey (Meleagris gallopavo)egg weight on certain egg traits and hatching performance. A total of 178 turkey eggs comprising of three different egg weight groups below 60 g (G I), 61 to 69 g (G II) and above 70 g (G III) were used for this study. Average egg weight (g), egg length (cm), egg breadth (cm) and egg volume (cm3) values increased wi...

متن کاملEffect of Hatching Egg Size on Hatchability and Chick Hatch-weight of Indigenous Venda Chickens
An experiment was conducted to determine the effect of hatching egg size on hatchability and hatch-weight of indigenous Venda chickens (Gallus gallus domesticus). Three different egg size groups classified into small: (<49 g) medium: (50-59 g) and large:(60-69 g) were used in the experiment. A complete randomized design was used for the experiment. Simultaneously a quadratic type equation was u...
متن کاملEffects of storage period and egg weight of Japanese quail eggs on hatching results (short communication)
This study was undertaken to determine the effects of storage period and egg weight of hatching eggs of Japanese quails on fertility, hatchability results. Eggs were obtained 150 females quails, all at 15 weeks of age. A total of 1942 hatching eggs were separated into 3 groups as light-weight (9.50-10.50 g), medium-weight (10.5111.50 g), and heavy-weight (11.51-12.50 g). Based on storage period...
