Attention should be paid to the addition of antibiotics in feed

Adding antibiotics to feed can not only prevent livestock and poultry diseases, but also improve livestock and poultry metabolism, promote livestock and poultry growth, improve survival rate and feed conversion rate. However, long-term continuous use will produce drug resistance, and residues in livestock and poultry products will bring harm to human health, which has been resisted by non-resistant products. Therefore, at present, the addition of antibiotics in feed should pay more attention to the quantity, methods and methods of addition, so as to minimize the harm of antibiotics.

? First, add categories

When adding antibiotics to the feed, we should also pay attention to the selection of special antibiotics for animals, use little or no common antibiotics, and change the type and dosage of antibiotics accordingly with the change of environmental conditions, and pay attention to environmental hygiene and disinfection at any time to further improve the efficacy of antibiotics.

Second, add quantity and uniformity

If oxytetracycline is used to treat livestock and poultry diseases, 0.1% can be added to the feed, while when used as a feed additive, only 10 grams per ton of feed need to be added. In order to ensure the curative effect, some farmers often increase the amount of addition, which not only increases the production cost, enhances the drug resistance of pathogenic bacteria, but also pollutes the environment and reduces the benefit. When using antibiotics, you should first make a premix, and then mix it into the feed, so that it can be mixed well. It is strictly forbidden to mix pure antibiotics directly into the feed, which will often lead to livestock and poultry poisoning due to uneven mixing.

? 3. Time of medication

An antibiotic will develop resistance after being used for a period of time, and long-term use of the same antibiotic will inhibit the normal growth and reproduction of some beneficial microorganisms in the intestinal tract. Strict control of medication time can effectively limit the residue of drugs in livestock and poultry products. If oxytetracycline calcium salt is used as a pig feed additive, it should be stopped 7 days before slaughter.

? IV. Incompatibility

There are many kinds of antibiotics sold in the market. if we do not pay attention to the incompatibility when using it, it will not only play a role in prevention and treatment, but also may cause poisoning and death of livestock and poultry. For example, tetracycline antibiotics have incompatibility with penicillin, sulfonamides and chloramphenicol.

? 5. Distinguish between different categories

There are different requirements for antibiotics in different livestock and poultry species and different growth stages of the same livestock and poultry. For example, proper feeding of antibiotics before and after breeding and litter birth in pigs can increase the conception rate, litter size and weaning litter weight, while the effect of using antibiotics in piglets will decrease at the age of 8 to 10 weeks. Similarly, oxytetracycline inhibits the activity of rumen microorganisms in adult ruminants, but has a better effect on young livestock. Liang Xiaoqin
