COMPARATIVE STUDY OF HATCHABILITY AND FERTILITY RATE AMONG LOCAL QUAILS

open access: yesThe Iraqi Journal of Agricultural science, 2020
An experiment was conducted to evaluate fertility, hatchability, egg weight and egg production traits from three different lines of local quails. A total number of 945 eggs (334, 321 and 290 for desert, brown and white, respectively), from 20 weeks of ...

Effect of the combination of white and red LED lighting during incubation on layer, broiler, and Pekin duck hatchability

open access: yesPoultry Science, 2017
&NA; Previous research has shown that providing light during incubation can have positive effects on hatchability and chick quality; however, white light alone has been observed to improve these factors only in pigmented broiler eggs and non‐pigmented ...

Effect of egg weight on chick weight, egg weight loss and hatchability in rock partridges (A. graeca)

open access: yesItalian Journal of Animal Science, 2010
This study was conducted to determine the effect of egg weight on chick weight, egg weight loss and hatchability in partridges. Eggs (847) obtained from rock partridges (44-46 weeks ages) were classified according to their weights as

The effect of eggshell thickness on hatchability of quail eggs

open access: yesVeterinary World, 2017
Background and Aim: The aim of the successful incubation period is to achieve maximum health chicks in each batch. Therefore, all factors affecting incubation have to be investigated in detail.

Effects of thermal manipulations during embryogenesis of broiler chickens on developmental stability, hatchability and chick quality.

open access: yesAnimal, 2016
Stress based on high temperature and humidity reduces the production performance of fast-growing broilers and causes high mortality. Temperatures higher than optimum have been applied to broilers in the embryonic period in order to overcome thermal ...

In ovo administration of Bacillus subtilis serotypes effect hatchability, 21-day performance, and intestinal microflora

open access: yesPoultry Science, 2021
: Recent research has tried to maximize broiler chick health and performance by utilizing commercial in-feed probiotics to inoculate fertile hatching eggs, and thus expose birds earlier to beneficial bacteria.

Effect of In Ovo Feeding of L-Glutamine to Chick Embryos [PDF]

open access: yesBrazilian Journal of Poultry Science, 2019
In ovo feeding (IOF), injecting nutrients into the amnion of the avian embryo may enhance hatchability, gastrointestinal development and serum metabolism changes. This hypothesis was evaluated with 5 IOF solutions containing L-glutamine.
