A kind of anti-resistant piglet nursery feed and preparation method thereof

Abstract

The invention discloses a culture feed for piglets, which mainly comprises corn, rice, full-cream puffed soybean, fermented bean pulp, peeled bean pulp, fish meal and the like. Yeast cell extract is added to enhance the immunity of piglets, and compound enzyme preparations and probiotics are used instead of high copper and high zinc, thereby lowering the environmental pollution, enhancing the digestion and absorption of the feed, and maintaining normal flora of the intestinal tract. Full organic trace elements are used instead of inorganic trace elements, thereby lowering the oxidization of inorganic salts on the feed and organisms. The invention also discloses a preparation method of the culture feed, which effectively reserves beneficial ingredients and discards harmful ingredients through the granulation process, thereby effectively reserving the nutritive value of the feed.

Description

technical field [0001] The invention relates to a nursery feed for piglets without adding antibiotics and a preparation method thereof, which belongs to the field of feed industry. Background technique [0002] Piglet nursery feed is a kind of feed that starts to be fed to about 15kg after weaning or 10 days after weaning. Piglets at this stage have a series of problems such as physiology, psychology, and environment, and it is the most difficult stage in a pig's life to raise. Psychological stresses such as leaving the sow, leaving the mother's milk, and separating the littermates into different pens; physiologically, the digestive system is not fully developed, the food source is changed from liquid breast milk to solid feed, and the immune system is underdeveloped, etc. ; The environment has changed from the farrowing room to the nursery room, and the gregariousness and nesting have all changed. Therefore, the nutrient supply at this stage is very important, depending ...

AI Technical Summary

Problems solved by technology

At present, the main way to solve this problem is to add some flavoring agents to improve the palatability. However, this method increases the feed intake, but the piglets have limited digestibility and cannot make good use of the nutrients in the feed, resulting in severe diarrhea in piglets.

[0005] 2. Digestibility of feed

[0006] 3. The immune system of piglets is not fully developed and there are many diseases

At the same time, the processing method of secondary granulation can take into account both the maturation of the feed and the activity of trace components. At present, there is no report on this formulation technology and preparation method in the world and at home.
