Procedeu de tratare a ouălor de gâscă: brevet MD nr. 2184

Abstract

The aim of this research was the study of hatching indices of eggs of different poultry species depending of their storage life. It is generally considered that eggs should not be kept for more than 7 days prior to incubation. Beyond this time chances of hatchability decrease considerably. Vitamins decay and membranes breakdown in time and so the embryo can often suffer early mortality. The study results showed that the highest hatching indices had the eggs with a short length of shelf life. At the same time it should be mentioned the strict compliance of hatching regime, as only the short deviation can cause disorders of embryonic development.
