It is described as sudden death of previously healthy, well-growing piglets with no noticeable clinical signs, since death occurs quickly, the contents of the intestine is with blood, the body is pale with a swollen abdomen, and diarrhea may be absent.

One of the actual tasks of modern livestock breeding is increasing the feeding efficacy. How can we achieve the best growth parameters without increasing the cost of feed? A simple answer is already found.
