In order to ensure that there are no residues of harmful substances such as chemical fertilizers, pesticides, hormones, antibiotics, veterinary drugs and chemical synthetic substances in beef, beef cattle breeding must be managed and produced in accordance with the relevant requirements of the green food production operation regulations. Cattle farm environmental conditions and protection 1. The terrain is flat, leeward, sunny, and dry. The cattle site should be higher than the local historical highest flood line, and the underground water level should be less than 2 meters. 2. The water quality must meet the Hygienic Standards for Drinking Water, and the amount of water is sufficient. It is best to use deep groundwater. 3. The barn site should be open and tidy, with convenient transportation, and keep a distance of more than 500 meters from the main highway. 4. The barn should maintain proper temperature, humidity, air flow, light and fresh clean air, and disable toxic insecticidal, sterilizing and antiseptic drugs. 5. The cattle farm sewage and sewerage treatment standards. Nutritional needs Green breeding requires scientific and rational preparation of feed based on the nutritional requirements of beef cattle at different stages of development. Drug additives have brought great benefits to the animal husbandry industry, but with the development of the times, the side effects caused by it are increasingly evident. The use of low-dosage antibiotics as an additive eliminates the beneficial microorganisms in the body while eradicating pathogenic bacteria and causes dysbacteriosis in the body. In long-term feeding, it also produces drug resistance and remains in animal products, causing public health problems. The adverse effects directly threaten human health and safety. Therefore, the use of feed additives must comply with the guidelines for the use of feed additives for the production of green foods. Misuse of antibiotics for non-compliance with the withdrawal period, or the illegal use of substances such as hypnotic sedatives, hormones, or hormones, can lead to the use of such drugs in beef. Residual excess. Therefore, the production of green beef should use new biological agents that can replace antibiotics and somatotropin. First of all, select animal-specific antibiotics with high safety and no drug residues, and avoid the use of drugs that are likely to produce drug resistance. Second, the method of use should be correct and reasonable. It must be mixed with the feed, and strict implementation of the standard withdrawal period, etc. Provisions to reduce drug residues and drug resistance. It is forbidden to use banned drug additives and strictly control the substances harmful to human health such as various hormones, antibiotics, chemical synthesis somatotropin and chemical preservatives into the milk to ensure the quality of the products.
