Enzymes activity in broiler chick yolk sac during post embryogenesis

Broiler chicks use supply of nutrients in their yolk sac the first days of post embryogenesis. But digestive enzymes activity in intestine and yolk sac has not been studied well in spite of extensive scientific information on this problem. That’s why this work aim has been broiler enzyme activity investigation in yolk sac, in pancreas, in intestine and serum for identifying ways of yolk usage during post embryogenesis.
