2020 for feed breeding industry, there is no doubt that the ban is the most important. At present, a variety of substitute anti-graft products in the market bear the heavy task of intermediate substitute anti-graft to a certain extent. Then, do you know all these common substitute anti-graft products?
1. There are many kinds of oligosaccharides. Currently, oligosaccharides used as feed additives mainly include fructo-oligosaccharides, galacto-oligosaccharides, mannan oligosaccharides, soybean oligosaccharides, isomaltose and xylose oligosaccharides. These oligosaccharides belong to short chain branching sugars, which cannot be decomposed by digestive enzymes secreted by monogastric animals themselves, but can be digested and utilized by beneficial microorganisms in the intestinal tract after entering the digestive tract, selectively promoting the proliferation of beneficial bacteria such as bifidobacterium, Lactobacillus and streptococcus.
2. As probiotics, the main function of probiotics is to regulate the balance of intestinal flora in animals, so it should be mainly used to prevent intestinal diseases.
Feeding enzymes can be roughly divided into digestive enzymes and non-digestive enzymes, which usually function at the nutritional level. For example, improve the activity of endogenous enzymes in digestive tract of livestock and poultry, supplement the deficiency of endogenous enzymes; Damage plant cell wall, improve feed utilization efficiency; Eliminate the anti - nutritional factors in feed, promote the digestion and absorption of nutrients.
3. As a kind of new additive, acidifying agent can reduce the pH value of feed in digestive tract and provide animals with a new additive suitable for digestive tract environment.
As a new antibacterial agent, antimicrobial peptides have broad spectrum antibacterial activity and are not easy to cause drug resistance of pathogenic bacteria, so they have many advantages as feed additives.
