Abstract

??????? ?.?.; ??????? ?.?. Egg physical characteristics play a great role in the processes of embryo development and its successful hatching. The most influential egg parameters are: weight, shell thickness and porosity, shape index, described as maximum breadth to length ratio, and the consistency of the interior. The average values of the physical characteristics mostly meet the requirements for embryo’s development. For the eggs, which parameters do not belong to the average range, the incubation process is more successful if the shell is thicker than average, the eggs are of the sharper shapes than the round ones, and the interior is more firm. The reported results of investigations for incubating the eggs, which weights are not within the average values, contain contradicting data. Both thick shell and firm interior, which are accepted to be higher than the average, lead to the increase of egg weight, which can, probably, tend to more successful hatching of the embryos from heavier eggs. ?????????? ?????????????? ??????? ??? ?????? ???????????? ???? ? ???????? ?????????????? ???????? ? ????????? ??????????. ???????? ????????? ??????????? ???? ????????: ???, ??????? ???????? ? ??????????, ?????? ?????, ???????????? ??? ????????? ???????????? ?????? ? ?????, ? ???????????? ???????????. ???? ?? ???????? ???????????????? ????? ????? ???????? ??????????? ??????????? ?????????????? ????????. ???? ????????? ?? ????? ? ??????? ????????, ??????? ????????? ????? ??????? ??? ??? ???, ??? ???????? ????? ??????? ????????, ??????? ????? ????? ?????????, ??? ???????? ?????, ? ??? ?????????? ????? ???????. ?????????? ???????????? ?? ????????? ???, ??? ??????? ?? ?????? ? ??????? ???????, ?????????????. ????? ??????? ???????? ? ??????? ??????????, ???????? ??????? ??????????? ? ????????? ??????????? ???????, ???????? ? ?????????? ???? ????, ???, ????????, ??????????????? ? ????? ???????? ?????????? ??????? ?? ????? ??????? ???.
