Incubation Relative Humidity Effects on Allantoic Fluid Volume and Hatchability

Effects of relative humidity during incubation on hatchability and body weight of broiler chicks from young breeder flocks.

We conducted an experiment to determine the effect of relative humidity (RH) during incubation on characteristics of hatched chicks from eggs produced by young broiler breeders. Eggs were collected for 6 consecutive d, every other week, in each of two trials from broiler breeder flocks at 26, 28, and 30 wk of age. The eggs were randomly distributed in machines according to RH treatments that we...

Effect of incubation humidity and flock age on hatchability traits and posthatch growth in Pekin ducks.

This study was conducted to determine the effect of incubation relative humidity (RH) from 14 to 24 d of incubation during 3 parental ages on hatchability and posthatching growth of Pekin ducklings. Egg production was divided into 3 age groups (25-35, 36-55, and 56-65 wk). A total of 21,600 hatching eggs was subjected to 55, 60, 65, and 70% RH from 14 to 24 d, whereas standard conditions were u...

تاثیر موقعیت قرارگیری تخم مرغ‌ها در دوره انکوباسیون بر تلفات جنینی و حجم مایع آمنیوآلانتوئیک در مرغ های مادر تخم‌گذار جهت استفاده از آن ها در تکثیر ویروس

The numerous apparent malformations of eggs from laying breeder flocks are affected by the increased age of the flocks. The bulking and spinning of eggs causes them to be placed in small end up (SEU) condition in the incubation period and eventually inoculation of the virus is done incorrectly. Present study was designed to investigate the effect of egg condition on embryos deaths, amnio-allant...
