Feed additives in the production and use of the following problems.
1. Abuse of antibiotics and hormones in feed additives In the production of early feed additives, people with low doses of antibiotics or sulfonamides to prevent livestock and poultry disease or diarrhea. This low-dose antibiotic will destroy the ecological balance of microorganisms (including pathogenic microorganisms) in the natural environment; residues in food will seriously affect human disease treatment and human inheritance.
Therefore, the United Kingdom, the United States, Japan and other countries are clearly stipulated in the feed additives can not use certain antibiotics, such as penicillin, streptomycin, oxytetracycline, lincomycin, neomycin dry wet trough, etc., can only use some High safety, and not with the clinical practice of livestock and poultry dedicated antibiotics. Some hormones, such as estrogen, androgen, are also not allowed to use.
2. Some trace elements in the amount of excessive or inadequate In the feed additives commonly used trace elements are iron, copper, manganese, zinc, iodine, selenium and so on. These elements into the body after the ion, molecular or complex structure of the state of the compound, the different state of the biochemical role is also different. Too little will produce deficiency, too many can cause poisoning or produce imbalance. So the content must be appropriate, and mixed evenly, otherwise it will play the opposite effect.
3. To exaggerate the role of feed additives Feed additives to balance the diet, promote livestock production, growth effect is yes. Generally 5% -25% higher than the control group without the use of additives. But some products in the advertising, too exaggerated its role, these unrealistic propaganda, should be wary.
A microbial feed additive is a microbial product that replaces or equilibrates one or more strains in an animal ecosystem. Narrowly speaking, it is a kind of microbial products that can stimulate the growth of their own beneficial bacteria and multiply the growth of harmful bacteria.
The traditional Chinese medicine microbial feed additive contains a large number of beneficial bacteria (active lactic acid bacteria, bifidobacteria, bacillus), compound enzyme, chelate peptide, mold fungicide, etc., as feed into the livestock and poultry body, can quickly multiply, on the one hand metabolites and intestinal toxins inhibit the growth of other harmful flora, on the other hand in the host body to form a normal microbial flora, the main synthesis of vitamins for the host, to provide nutrition and prevent the invasion of pathogens.
