The importance of the yolk sac: The yolk sac enters the abdominal cavity during the last days of incubation, and in newly hatched chicks it constitutes (15-20%) of its live body weight, then decreasing to approximately 1 g on the fourth day of hatching. In the meantime, the chicks can benefit from the contents of the yolk sac. As food. Yolk is utilized in chicks in two ways simultaneously. The first method is by transferring its components directly into the blood circulation, and the second is by transferring it through the yolk sac channel to the small intestine, which remains open upon hatching and then narrows with age due to the accumulation of lymphocytes that block this channel within 48 hours. Mostly completely within 72 hours, after which the yolk sac duct turns into lymphatic tissue. Upon hatching, the yolk is composed of 50% water, 25% protein, and 25% fat. It therefore provides the newly hatched chicks with fats and proteins before they switch to eating feed rich in sugars and protein.
