Conventional Manner

An experiment was conducted to evaluate the effects of two different hatching-egg storage environments on the subsequent performance of broiler chickens. The two environments involved: (1) an improved egg storage method consisting of eggs packed small endup on fiber trays, enclosed in vinylidene (Cryovac) bags flushed with nitrogen gas; and (2) eggs packed in the conventional manner small end-down on fiber trays. The effects of preincubation fumigation was also evaluated. A 20-min fumigation was conducted prior to packing the eggs using 1.5 ml formalin and 1 g potassium permanganate per 0.028 m3 of fumigation chamber. Fumigated eggs were ventilated 24 hr before packaging. The improved storage method resulted in the higher hatchability of broiler chicks, lower mortality, higher growth rate, and higher monetary returns to 8 weeks of age compared with chicks hatched from eggs stored under conventional conditions. There were no significant differences in the performance of chicks hatched from eggs stored for 23 and 30 days under the improved storage method and chickens hatched from eggs held only 2 days prior to incubation. Fumigation effects on subsequent bird performance appeared to have no important effect. It is concluded that deleterious effects on chick performance associated with the prolonged storage of hatching eggs under conventional methods can be reduced or eliminated by using improved egg storage methods.

The embryonic period of the domestic turkey is characterized by a relatively high level of mortality (Kosin & Mun, 1960, 1965). The aim of the investigation reported below was to analyse the significance of certain changes observed in turkey embryos doomed to die because of either congenital or experimentally induced defects. The study was based on hatching eggs obtained in 1963 and 1964 from the Broad Breasted Bronze turkey stock maintained at that time at Washington State University for genetic investigations, and from a mass-mated flock of non-selected White Leghorn chickens. Only such criteria as size and shape of the egg and soundness of the shell were employed in choosing eggs for use. The eggs were brought daily to the storage room a few hours after laying and stored at 13·5 °C and 85 % relative humidity for 1–14 days. Following this, the eggs were incubated at 37·5 °C and 60 % relative humidity for 1–15 days.
