Study of The Effect of Folic Acid on The Phenotypic Appearance of Local Chicken Embryos

Folic acid is a type of vitamin essential for poultry health. It plays an important role in the formation of DNA and cell division. It also helps reduce the risk of neural tube defects in the fetus. It is important in the formation of red blood cells and helps them grow and perform their functions in a healthy manner. In addition, it is considered essential for healthy embryonic development.In this study, the effect of folic acid on the external appearance of local chicken embryos was studied. 90 fertilized eggs of equal sizes were collected and divided into three groups, each containing 30 eggs. The first group was injected with folic acid at a concentration of 20 micrograms, the second group with folic acid at a concentration of 40 micrograms, and the third group was not injected and then placed in incubators.This study concluded that there was no difference between uninjected embryos and embryos injected with two different concentrations of folic acid 20 and 40 micrograms at the age of 7 days. It was noted that folic acid enhanced the growth of injected embryos at the age of 14 days, and at the age of 21 days, egg hatching was normal and no abnormalities were observed in the chicks.
