Hemorrhagic bowel syndrome (HBS) or necrotic enteritis was observed in only 2-5% of pigs at the beginning of fattening in Europe, and only in isolated cases in the United States from 1959 to 1970. In recent decades, the syndrome has become more prevalent throughout the world, both in newborns, weaned piglets, fattening pigs, and sows. 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.

It is known that antibiotics are introduced into rations and water so that the birds and animals quickly gain weight or consume less food. However, the use of antibacterial preparations leads to the development of resistance. Therefore, antibiotics should be applied only when necessary (as per indications).

Intestinal health is one of the most important and complex aspects associated with animals feeding. This concept includes functionality and integrity of the gastrointestinal tract, the condition of microflora, its symbiosis with the host, which also plays a very important role.

How long pigs are to be on the farm before the meat factory depends on how quickly the livestock reaches the market weight. The earlier animals eat the necessary amount of feed, the less time will be spent on growing them up. Pigs should eat 3 kg of feed in order to increase the body weight by 1 kg. That is why the manufacturers are worried about the problem of feed intake and the taste qualities of feed components.

Mastitis remains to be wide spread and the most expensive disease of milk cattle worldwide. According to resent studies, the costs for its treatment are above 26% of all expenditures related to diseases of milk cattle. Economic losses due to mastitis are two times higher than those due to animal infertility. How can this problem be sold?

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.
