The pigs raised now grow fast. Are they fattened? Is there a regulatory requirement for the feed you eat? What kind of medicine do you take when you get sick?

In recent years, with the rapid development of economy, the continuous improvement of people's living standards and the gradual increase of pork consumption, the traditional farming methods have been unable to meet the demand, so the modern aquaculture industry characterized by moderate intensification arises at the historic moment. So now farmed pigs are growing fast, are they fattened? Are there any management requirements for the feed you eat? What kind of injection do you take when you get sick?

Now that pigs grow fast, are they fattened?

1. The rapid growth of modern pigs is mainly due to the progress of genetics and breeding technology of breeding pigs. In the process of domestication for more than 10,000 years, many changes have taken place in pigs: the reproductive performance has been improved, the growth rate has become faster, and the quality of meat has changed. At present, most of the pigs in our country are crossbred from Duroc, Landrace and large White introduced from abroad. This kind of commercial pigs have the advantages of saving feed and grain (native pigs eat 4 jin feed to gain 1 jin meat, modern du long large commercial pigs eat 2.8 jin feed to gain 1 jin meat), and grow fast (native pigs usually grow to 75 kg in 8 months. Du long large commercial pigs can grow to 120 kg in 6 months), high lean meat production (the proportion of lean meat output of native pigs is generally about 40%, while the proportion of lean meat output of du long large commercial pigs can reach more than 60%), large size and other advantages. It is normal for high-quality pig breeds to be fenced in about 160 days, and the fencing cycle of pigs with better foreign breeds is shorter.

2. The improvement of feed quality also plays a very important role. The application of modern feed science and technology has significantly improved the conversion rate of compound feed in China, from 4:1 to 3:1. It used to take a year to raise a pig, but now it can be done in six months, which is inseparable from the progress of nutritionally balanced feed and breeding technology. no, no, no.

3. In addition, by improving the breeding environment and implementing harmless treatment of livestock and poultry manure, the problems of major epidemic diseases and antibiotic residues have been gradually solved, and the growth cycle of pigs has been gradually shortened, and pigs can grow to about 100 kilograms.

Are there any management requirements for the feed farmed pigs eat now?

1. Feeding balanced feed to pigs in breeding is an important factor for pigs to grow healthily. Feed consists of feed raw materials and feed additives. The feed raw materials and feed additives used in our country are licensed, that is, those that are approved can be used, and those that are not approved or banned can not be used. The Ministry of Agriculture has issued a "feed raw material catalogue", which is not updated regularly. Substances outside the catalogue that are used as feed materials shall be scientifically evaluated and listed in the catalogue by the Ministry of Agriculture before they can be used.

2. Feed additive is a feed ingredient with small amount but great effect in feed. without feed additive, it is impossible to prepare feed which can not only meet the needs of animals but also balance nutrition. Additives can be divided into three categories: nutritional additives, general additives and drug additives, and the proportion in feed is generally no more than 4%. The proportion is high, and the feeding cost is increased, which is not cost-effective for farmers. Traditional single feed can only solve the problem of "satiety" of live pigs, while nutritional additives mainly solve the problem of "eating well" of live pigs. Adding an appropriate amount of drug additives to feed can effectively prevent and control the common and multiple diseases of live pigs. the state has formulated a strict Code for the use of Feed Drug Additives, which is carried out in accordance with the regulations on the Administration of Veterinary drugs. China explicitly forbids the addition of sedative, hypnotic and anticonvulsant drugs such as phenobarbital in feed. It is not necessary to add sleeping pills to make pigs sleep less and gain weight quickly, because captive pigs have very little activity and there is no need to use tranquilizers.

3. In order to ensure the quality and safety of feed, the Ministry of Agriculture carries out routine monitoring of feed quality and safety throughout the country every year. In the first half of 2017, the qualified rate of all kinds of commodity feed was 96.43%. It can be said that China's feed products are generally safe and reliable, and the sustainable and healthy development of animal husbandry is guaranteed.

What kind of injections do pigs take when they get sick?

1. When pigs get sick in breeding, the necessary treatment is inevitable, and it is also the case in developed countries such as the United States and the European Union. Pigs are given veterinary drugs, and usually, in order to prevent the risk of infectious diseases in healthy pigs, breeders are vaccinated against specific diseases. In view of major animal epidemics such as foot-and-mouth disease, the state shall take compulsory immunization measures to uniformly prevent and control such risks; when group bacterial diseases or other group diseases occur in live pigs, breeders will generally be under the guidance of veterinarians, feeding therapeutic veterinary drugs to prevent and cure diseases; for individual pigs, such as trauma, dystocia, etc., it is generally subject to special treatment by veterinarians.

2. Veterinary medicine is an indispensable important input in promoting the safe production and healthy development of aquaculture. According to the Animal epidemic Prevention Law and the regulations on the Administration of Veterinary drugs, the use of drugs in the process of animal breeding must abide by the relevant regulations. First, veterinary drugs approved by the state that meet the requirements should be used, and prohibited veterinary drugs or compounds may not be used; second, human drugs should not be used, and hormone drugs should not be used in feed or drinking water; third, veterinary prescription drugs should be used according to the prescriptions of licensed veterinarians; fourth, veterinary drugs should be used in strict accordance with the animal varieties, indications, usage and dosage stipulated in the instructions for the use of veterinary drugs, and the drug withdrawal period should be strictly enforced. Fifth, farms / households should establish standardized drug use records.

3. At present, China has never approved hormone drugs to promote animal growth, and the approved hormone drugs are mainly used to treat breeding and obstetrical diseases, which is consistent with the regulations of the European Union. Up to now, the Ministry of Agriculture has only approved more than 10 kinds of antibiotics such as oxytetracycline to be used as pharmaceutical feed additives, and strictly stipulated the animal species, usage and dosage, drug withdrawal period, and so on, which are basically in line with international standards.
