Abstract
BECKER et al. (1963, 1964) and Becker (1964) obtained improved hatchability from storing hatching eggs of chickens, quail and turkeys in Cryovac (polyvinylidene chloride copolymer) bags. Proudfoot (1964) also found that hatchability was improved by preincubation storage of eggs in Cryovac. Warren et al. (1965) used Cryovac bags as liners for egg cases and suggested that unless storage extends beyond two weeks, with poor holding conditions, or the eggs are shipped long distances, this procedure is unnecessary.Krueger et al. (1965) compared storage in Cryovac with shelf storage on open egg flats, and in sealed cases. With chicken eggs the hatch differences between storage in Cryovac bags and in sealed cases were minor, but both of these methods were superior to storage on open flats, even after only seven days of storage. Turkey eggs held in egg cases, hatched slightly better than when stored in Cryovac bags.Since Cryovac containers …
