Материалы к изучению динамики роста кишечника у цыплят в эмбриогенезе

Abstract

The growth dynamics of chicken intestine was studied in embryogeny in connection with the transition of the foetuses to intraintestinal nutrition. The formation of the wall of small intestine, and its topography by every five days are described. The irregularity of growth in all digestive system areas is noted. A slower growth is observed during the first 9 days of incubation when tissues are laid and formed. On the ninth day the intestine begins functionning, and after that a quick growth of all its areas is observed. The author suggests to devide the development of the intestine in embriogeny into 2 stages — prefunctional and the functional one.
