Over the years, due to genetic selection, improvement of the characteristics of laying and meat poultry with less feed consumption per kilogram of body weight gain has been achieved (FCR). As the productivity of poultry increased, the demand of embryos for nutrients changed. However, the chemical composition of an egg has remained practically unchanged, and therefore, it began providing the embryos with suitable substances with the help of in ovo technology. Improvements in hatching were achieved through the administration of fructose, sucrose and grape seed extract (GSE), while the weight of a one-day-old chick is affected by the injection of amino acids with glucose and magnesium. In addition, amino acids and carbohydrates applied to an egg have contributed to an increase in the activity of digestive enzymes and maturation of the intestine.
