Effects of Maternal Body Weight, Some Blood Parameters and Egg Quality Traits on Fertility, Hatchability and Chick Weight of Japanese Quail
A total number of one hundred and fifty-three females and males of Japanese quail at 14 weeks of age were used with sex ratio 2 female / 1 male to study the effect of maternal body weight, some blood parameters and egg quality traits on fertility% (F%), hatchability% for total and fertile eggs (H/TE % and H/FE %), and chick weight (CW). Birds classified into three groups (light, medium and heav...

متن کاملEffects of hen production cycle and egg weight on egg quality and composition, hatchability, duckling quality, and first-week body weight in Pekin ducks.
This study was conducted to determine the effect of hen production cycle (HPC) and the effect of egg weight (EW) at the same egg production level on egg quality, egg composition, hatchability, duckling quality, and first-week BW in Pekin ducks. For HPC, hatching eggs were obtained from different Pekin-duck breeder flocks, aged 31 wk for the first production cycle (HPC1) and 78 wk for the second...
متن کاملEffects of Egg Storage Material and Storage Period on Hatchability in Japanese Quail
The present study aimed to determine the effects of different storage materials and storage period on some hatchability traits of Japanese quail (Coturnix coturnix japonica) eggs. A total of 32 male and 102 female quail (twelve weeks of ages) were housed in multiple-bird cages. Eggs laid were divided into three groups with respect to the period of storage (I = 1, 2 and 3 days, II = 6, 7 and 8 d...
