ukrthis is a delicious era, we can choose our favorite meat, eggs, milk on the shelves at will. Yet chemical terms such as "clenbuterol" and antibiotics have suddenly popped out, which amplifies public concern about animal feed additives. So, is feed additives not necessary? How to solve the quality and safety problem of animal food?

the appropriate amount of reasonable use of feed additives is allowed

"In Taiyuan's small shop area of the vegetable market, is picking eggs, Aunt Liu Guiqin constantly complain.
.Like Aunt Liu, as food quality and safety incidents continue to occur, more and more people are now paying more attention to food safety: foreign eggs are not as good as earth eggs; With this concern, feed additives, a term that is unfamiliar to most people, began to come into people's view.

, why should feed additives be used in livestock and poultry farming, without not?
.He Dongchang, director and researcher of the Institute of Livestock and Veterinary Research of the Provincial Academy of Agricultural Sciences, explained that the growth and development of animals, like humans, need energy, protein, amino acids, mineral trace elements and other nutrients, when ordinary feed can not meet the needs of animal growth, some small or trace substances in the form of additives added to the feed, to improve feed utilization efficiency, increase the palatability, promote normal development of animals, accelerate growth, prevention of animal diseases, easy to save and save feed and other effects.
.It can be said that the production and application of feed additives is a sign of the level of feed, without feed additives, it is difficult to prepare to meet animal needs, nutritional balance of feed.
.Feed additives can be divided into nutritional additives and non-nutritional additives. Nutritional additives include minerals, vitamins, amino acids, mainly used to meet the growth and development of livestock and poultry needs of nutrients. Copper, for example, has a role in promoting growth and development; selenium and vitamin E have a role in increasing reproduction rates. Non-nutritional additives include enzymes, herbal additives, sweeteners, antibiotics, etc. Enzyme preparations can balance the bacteria in livestock and poultry, sweeteners are used to increase the taste of feed, China's unique herbal additives, not only have health care effect, but also can improve the flavor of livestock and poultry products, taste, is called green additives in the industry.
.A wide variety of feed additives, with the development of animal nutrition, often new feed additive varieties come out, some feed additives will be eliminated or banned, so the varieties of feed additives are often in the new and old replacement. At present, the feed additives allowed by the Ministry of Agriculture of China are amino acids, vitamins, mineral trace elements, enzyme preparations, feeding microorganisms and other 191 kinds of 191 kinds;
.Animal food safety incidents are mostly caused by illegal use or excessive use of feed additives
ukr feed additives in the use of feed, although small, but the role is very large, it determines the quality of the feed. The wide application of feed additives can shorten the feeding cycle, reduce the cost of breeding, give full play to the production capacity of animals, has significant economic and social benefits.
.　　But with the use of feed additives, meat, eggs, milk taste decline and animal food quality and safety and other issues, He Dongchang researchers believe that this is in the production of agricultural and sideline products, and in a certain period of time will be long-term existence of the "quality" and "quantity" contradictions. Because in general, the quality of livestock and poultry products and growth rate is inversely proportional. But over the years, in order to meet market demand, the domestic aquaculture industry system and technology system around the increase in production, in terms of quality and safety is relatively weak.
.　　In fact, from a genetic point of view, eggshell color, egg size is determined by the variety of chicken, and nutritional composition is not much related. However, due to different varieties of eggs on the synthetic egg white requirements are different, chicken can only produce 130 eggs a year, eat feed additives of chicken can produce nearly 300 eggs, a lot, the taste is poor. Pork is also the same reason, according to the pig first long bones, muscles, and then deposit fat growth order, if in accordance with some feed manufacturers publicity of the "March 3" "April fat" column, taste less than the feeding time is long, fat content reached a certain proportion of pork.
.　　Of course, it is precisely because of the unique role of feed additives, decided that the amount of addition must meet a certain proportion, there are strict limits, otherwise the residue of feed additives will pollute the environment or through meat, eggs, milk and other consumer health has a certain impact. For example, excessive heavy metals copper and zinc can lead to the imbalance of trace element balance in the soil, and excessive selenium can cause animal and poultry poisoning. The appearance of green pork is also the reason that pigs in the raw and long-term consumption of high copper feed, resulting in heavy metal copper residue in the body, contact with the air into copper oxide. At the same time, if you add heavy metal to the feed too much, farm fertilizer can not be called green organic fertilizer.
.　　For this year's "March 15" period exposed "clenbuterol" incident, He Dongchang said, "Clenbuterol" learned to be beta-adrenal receptor agonists compounds, introduced in the early 1990s. Feed "clenbuterol" pigs, lean meat, color red, sell good, some slaughterhouses and pig dealers will buy at high prices, farmers are also very easy to use, grab the surface of the medicine into the feed on the line. But later found that the use of "clenbuterol", the residue exceeds the standard, will endanger human health, easy to cause poisoning. In 2002, the Ministry of Agriculture, together with the Ministry of Health and the State Drug Administration, jointly issued a list of "clenbuterol" bans, and the Supreme People's Court and the Supreme People's Procuratorate also clarified the basis for the illegal production, sale and use of "Clenbuterol".
.　　Feed additives, closely related to human health are antibiotics, although antibiotics can promote animal growth and prevent bacterial infection, but long-term large-scale use will lead to drug resistance problems and animal body residues, many countries in the world have made strict provisions on the use of antibiotics, China's Ministry of Agriculture currently allows the use of antibiotics in the feed of 24 kinds of drug additives, and according to different breeds, strictly prescribed the use of different antibiotics. Only after the drug break period, have eaten animal and poultry products containing antibiotic feed additives can be marketed.
ukr
strengthen market supervision, the development of green, efficient feed additives, is the key to solve the animal food quality and safety
ukr feed accounted for 60%-80% of the cost of aquaculture, feed additive sourcing price is not cheap, but why illegal, excessive use of feed additives are also often prohibited? He Dongchang researcher told reporters, because feed additives in addition to meet animal nutritional needs, but also can improve the utilization rate of animals on feed, save food, prevent disease, increase the phase, such as feed to add large doses of copper, zinc, etc. can significantly increase the growth rate of pigs, so that pig skin red hair bright, appear extraordinary appearance.
ukr
, how to strengthen the supervision of feed additives?
.　　Cheng Jianguo, a senior animal priest at the provincial feed animal medicine supervision institute, said in an interview that due to the current dispersal of domestic aquaculture production and operation, the market circulation of meat, eggs, milk, nearly 3/4 by pig farms, retail farmers to provide, which is a major regulatory problem. However, in recent years, our province has been increasing the special governance efforts, more than 500 head of large-scale farmers, one village and one household of retail farmers, to carry out random spot checks, require farmers to set up breeding files for livestock and poultry, the use of feed must be a formal production license enterprises produced by the batch number of feed, at the same time, also increased the inspection of home-grown feed, and strive to strengthen the quality and safety of animal food from the source.
.　　But we are faced with the reality that the aquaculture industry is a low-profit, high-risk industry, the market volatility, farmers for their own interests, will one-sided pursuit of economic benefits. Therefore, to solve the problem of animal food safety, in addition to improving the quality and safety system as soon as possible, but also to speed up the modernization of the aquaculture industry, improve the level of agricultural production organization, to provide farmers with scientific breeding knowledge, improve standardized breeding skills; On the other hand, researchers should also stand at the height of history and politics, develop green and efficient feed additives and promote scientific breeding model, under the premise of safety, to ensure the supply of livestock and poultry products.
