The function of rennin is to curdle milk proteins by converting the soluble protein caesinogen into the insoluble protein caesinogen. If the new born mammal is unable to produce rennin, then the soluble milk proteins would just pass through the stomach into the duodenum like water. This is bad because the milk proteins would not be able to get digested by the pepsin. However, if there is rennin, the converted insoluble milk proteins would be abe to stay in the stomach long enough for the pepsin to digest it into polypeptides.
