“…What was surprising, however, in the light of the reputed impermeability of the Cryovac plastic to C0 2 (c.f. Davis and Beeckler, 1962), was that the albumen of eggs stored within Cryovac bags and kept in the storage chamber with C0 2enriched air showed the C0 2 concentration approaching that of the non-stored eggs. Obviously, the extraneously added C0 2 managed to move across the boundary of the plastic bag and to become incorporated into the egg's albumen.…”

The main objective of the present study was to examine the effect of storing White Leghorn eggs in Cryovac bags and in COs-enriched air (1.5% CCh) on the livability of embryos during subsequent incubation. The secondary objective was to study the pattern of CO2 concentration in the egg albumen following oviposition and its possible relationship to embryos' viability. The eggs were kept for 0, 2, 3, and 4 weeks at 15.S°C. The results (1) pointed to a "sparing" effect of plastic bag storage and a depressing effect of the C0 2 treatment on hatchability, and (2) showed that during storage in "normal" air, the egg suffered a rapid loss of CO; (from its albumen. Two principal conclusions were reached: (1) under the conditions of the study, the beneficial effect on hatchability derived from storing eggs in Cryovac bags was attributed to increased humidity within such environment and (2) the C0 2 concentration in the egg albumen is not a major factor for maintaining the inherent capacity of the egg to hatch following an extended period of pre-incubation storage.
