Morphohistometrical study for prevntriculus in pre and post-hatching broiler chicks

Abstract

The present work is designed for morphological and histological study to evaluate the development and growth of the proventriculus of pre-hatching and post-hatching chicks Ross 308 of the proventriculus in the 11th, 15th days of pre-hatching, and 7th, 14th days of post-hatching of broiler chicks Ross 308, the avian stomach has two chambers. The first chamber is known as the proventriculus (glandular), and it is where gastric juices are produced.The second chamber is a mechanical part known as the ventriculus or gizzard. and was undertaken on 60 chick embryos obtained from incubated broiler chick eggs Ross 308 (Gallus gallus domesticus) 30 chick embryos were collected at stage 37 (Hamburger and Hamilton, 1951) Hand H (11 days of pre-hatch ) and 30 chick embryos were collected( H and H) at stage 41 (15 days of pre-hatch). 60 chicks were collected at 7 days and 14 days post-hatching. The proventriculus color, shape, and position had been revealed by a morphological study. The length, width, and weight total of the proventriculus were progressively increased to use Electronic Vernia and electronic balance. Chicks of proventriculus were formed from four tunics in this histological study: tunica mucosa, tunica submucosa, tunica muscularis, and tunica serosa.
