Eggs weight of Japanese quail vs. eggs quality after storage time and hatchability results
The aim of the performed investigations was to compare eggs of Japanese quail layers of different weights with regard to their shape, selected traits of the content following various times of their storage as well as the results of hatchability and body weight of one-day old chicks. Hatching eggs were divided into four groups: group S – up to 10.50 g, group M – from 10.51 to 11.50 g, group L – ...
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...
متن کاملEffect of Pre-Incubation Storage Periods on Weight Loss, Embryonic Development, and Hatchability of Pullet Eggs
This study was carried out to determine the effect of pre-incubation storage periods on egg weight loss, embryonic development and hatchability of hatching pullet eggs. Three hundred eggs were used for this experiment. The eggs were sourced on five different days (sixty eggs per day) at three days interval (day 0, 3, 6, 9, and 12) and weighed. The sixty (60) eggs collected on each day were subd...
متن کاملEcological and Social Factors Affecting Hatchability of Eggs
--Hatchability, defined as the proportion of eggs surviving to the end of incubation that hatch, varies among populations of birds. Here, I examine the effects of a variety of variables on hatchability in a comparative analysis of 155 studies of 113 species. Of the ecological nd geographical variables considered, latitude, diet, and nest type explain a significant amount of the variance in hatc...
