Abstract

The article presents the results of studies on prenatal feeding of chicken embryos of meat direction of productivity of the Cornish breed. Solutions of exogenous carbohydrates: glucose and dextrin were injected into the amnion of the embryo on the 18th day of incubation. As a result of studies, it was found that embryos are able to absorb both exogenous glucose and dextrin. It was shown that carbohydrate injections into the incubation egg during the prenatal period of development did not reduce the incubation quality of the eggs, and contributed to an increase in the growth rate of meat chickens. Chickens hatched from eggs injected with dextrin in the prenatal period of development had a significantly greater live weight at 7 and 21 days of age compared with the control group.
