Add antibiotics to feed should pay attention
The addition of antibiotics to feed can not only prevent livestock and poultry diseases, but also improve the metabolism of livestock and poultry, promote the growth of livestock and poultry, increase the survival rate and feed conversion rate. However, long-term continued use of a large number of drugs will produce drug resistance, and it will cause harm to human health in livestock and poultry products. It has been resisted by non-resistant products. Therefore, the current addition of antibiotics in feeds should pay more attention to the quantity, methods, and methods for adding antibiotics.
First, add species
Adding antibiotics to feed, but also pay attention to the use of animal-specific antibiotics, use less or no antibiotics shared by humans and animals, and change the type and dose of antibiotics accordingly with changes in environmental conditions, pay attention to environmental hygiene and disinfection at any time to further improve antibiotics effect.
Second, add the number and uniformity
For example, when oxytetracycline is used to treat livestock and poultry diseases, 0.1% can be added to the feed, and when used as a feed additive, only 10 to 15 grams per ton of feed should be added. In order to ensure efficacy, some farmers often increase the added quantity. This not only increases the production cost, increases the resistance of pathogens, but also pollutes the environment and reduces the benefits. When using antibiotics, they should be made into premixes and then mixed into the feed, so that they can mix well. It is forbidden to mix pure antibiotics directly into the feed. This will often lead to livestock and poultry poisoning due to uneven mixing.
Third, medication time
An antibiotic will produce drug resistance after a period of use, long-term use of the same antibiotic will inhibit the normal growth and reproduction of certain beneficial microorganisms in the intestine. Strictly controlling the time of medication can effectively limit the amount of drug residues in livestock and poultry products. If oxytetracycline calcium salt is used as an additive for pig feed, it should be discontinued 7 days before slaughter.
IV. Incompatibility
There are many types of antibiotics sold on the market. If you do not pay attention to incompatibility during use, you will not only fail to achieve preventive treatment, but may also cause animal and poultry poisoning to die. Such as tetracycline antibiotics and penicillin, sulfa drugs, chloramphenicol have incompatibility.
Fifth, distinguish between various types
There are differences in antibiotic requirements for different types of livestock and poultry, and different stages of growth of the same livestock and poultry. For instance, if pigs are fed appropriate amounts of antibiotics before and after mating, the fertility rate, litter size and weaning weight may be increased. The use of antibiotics will decrease when they are 10 weeks old. Similarly, oxytetracycline, when used in adult ruminants, inhibits the activity of rumen microbes and has a better effect on young animals.
The working process of the washing machine consists of four processes: water inlet, laundry, drainage, and dehydration. In a semi-automatic washing machine, these four processes are controlled with corresponding push-button switches. In a fully automatic washing machine, these four processes can be automatically run in sequence until the end of the laundry. Industrial washing machine features
