Green cattle breeding method

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.

I. Livestock 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 Standard for Drinking Water, and the amount of water is sufficient. It is better to use deep groundwater. 3, barn venues should be open and tidy, and convenient transportation, and maintain a distance of 500 meters above the main highway with the main road. 4. The cowshed should maintain suitable temperature, humidity, air flow, light and fresh clean air, and disable toxic insecticides, sterilization and antiseptic drugs. 5, cattle farm sewage and sewerage treatment standards.

2. Beef Breeding and Matching Beef cattle raised in China are mostly hybrids of imported species such as Simmental and Charolais and domestic cattle, and beef cattle with fast growth, strong disease resistance and local growth conditions should be selected. The breeds are reared and combined with the breeding of frozen semen from the best bulls for selection. For beef cattle purchased off site, they must undergo strict quarantine and disinfection.

Third, the nutritional needs of green beef cattle breeding according to different developmental stages of nutritional needs, scientific and rational preparation of feed. Feed is an indirect food for humans. Toxic and harmful substances in feed will directly harm human health. More and more studies have found that common human cancers, malformations, drug resistance and certain poisoning phenomena are related to the residues of antibiotics, hormones and other synthetic drugs in meat, eggs and milk. The excessive use of chemical fertilizers and pesticides will lead to higher residues of chemical fertilizers and pesticides in forage materials, which will lead to increased drug residues in beef. Therefore, the raw materials for green culture must come from grassland and planting bases in pollution-free areas. .
Drug additives have brought great benefits to the animal husbandry industry, but with the development of the times, the side effects caused by it have become increasingly apparent. 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 meet the guidelines for the use of feed additives for the production of green foods, abuse of antibiotics such as overdosage, non-compliance with the withdrawal period, or illegal use such as hypnotic sedatives, hormones or hormone-like substances, will lead to This type of drug remains excessive in beef. Therefore, the production of green beef should try to use new biological agents that can replace antibiotics and somatotropin, such as probiotics, acidulants, enzyme preparations, Chinese herbs, oligosaccharides, phospholipids, humic acids, etc. Residual veterinary drug additives instead of antibiotic additives, even in the production of antibiotics must be used, but also the rational use of antibiotic growth promoters, first of all to choose a higher safety, animal antibiotics without drug residues, and avoid the choice of easy to produce drug resistance Drugs; Second, the use of methods should be correct and reasonable, must be mixed with feed, and strict implementation of the standard withdrawal period and other provisions to reduce drug residues and drug resistance. It is forbidden to use banned drug additives and strictly control substances that are harmful to human health such as various hormones, antibiotics, chemical synthesis of somatotropin, and chemical antiseptics into the milk to ensure the quality of the product.
