[Comparative characteristics of the protein composition of the liver of heterosis hybrid chick embryos].
To reveal the peculiarities of the development of biosynthetic function of the liver, comparative morphological study of this organ was made together with electrophoretic analysis of water-soluble proteins from the liver of initial breeds and their hybrids at various stages of embryogenesis. The data obtained indicate that at final stages of embryogenesis the growth of the liver in hybrids is more intensive, the size of the liver at hatching being larger in the hybrids as compared to that in the initial breeds. Protein composition of the liver in hybrid embryos to the moment of hatching is similar to that in the adult organism. Total protein content and the content of separate fractions in hybrids are higher than in either of the parental breed, being usually more similar to those found in the maternal breed.
