Heritabilities and Genetic Correlations for Egg Weight Traits in Iranian Fowl by Multi Trait and Random Regression Models
Objective: The main objective of this research was estimation of genetic parameters for five consecutive measurements of egg weights in Isfahan fowl using multi trait model and random regression models. Methods: The statistical models included generation-hatch as a fixed effect, weeks of age as a covariate and additive genetic and individual permanent environmental effects as random effects. Th...

متن کاملEffects 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 کاملEffect 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...
