How to scientifically raise pigs?

How to scientifically raise pigs \ x0d \ x0d \ In recent two years, with the continuous rise of pig prices, more and more farmers have made money by raising pigs. However, in such a good market, some pig farmers do not make money. The main reason is that raising pigs is unscientific and epidemic prevention and health care are not in place. In our opinion, in order to realize the high efficiency of raising pigs, we must do a good job in piggery construction, variety selection, feed quality, epidemic prevention and scientific management. \x0d\ 1。 The construction of pigsty is very important, because pigs are accompanied by life from entering the pen to leaving the pen. The pigsty construction includes pigsty site selection and pigsty construction. \x0d\ 1。 Location of pig house: Whether the location of pig house is reasonable or not determines the success or failure of epidemic prevention and the healthy growth of pigs. Judging from the location habits of local farmers' pig houses, most of them are selected on the north side of the road and the south side of the main house. There is no problem from the construction of pig houses alone, but it is unreasonable to consider human health and pig epidemic prevention. First of all, the south wind is the main wind direction in the local summer. In summer, the high temperature and strong smell of pig manure directly pollute the living environment and affect people's health. From the aspect of pig epidemic prevention, the south of the main house is generally a gate or road, which is the only place where people come and go. The pigsty near the gate or road is easily polluted by bacteria and viruses carried by passing vehicles, long-distance and high-flow people, which is not conducive to the prevention and control of pig epidemic. Therefore, it is suggested that qualified farmers should try to build pig pens in the north of the main house where pedestrians are not easy to get involved, so as to reduce the occurrence of epidemics. \x0d\ 2。 Construction of pigsty: The basic requirements of pigsty are ventilated and dry, warm in winter and cool in summer. Single row pigsty should be built in the north-south direction, so that both sides can get sunshine. The height of pigsty should be convenient for people to get in and out of management, and also conducive to ventilation and lighting. The roof of the pigsty should be fully insulated, the walls should be smooth for cleaning and washing, and the ground should be hardened and kept dry. Boars and sow houses can be attached with outer rings. Only by keeping the pen dry often can we reduce the breeding of viruses and germs. Only in this way can we reduce diseases and keep pigs healthy. \x0d\ Second, the key to seed selection is to change "ternary" pig breeding into ternary hybrid pig breeding, and give full play to the advantages of Landrace pig's roughage tolerance, high reproduction rate, high lean meat rate and high feed reward of Duroc pig. Ordinary farmers can buy binary sows that have passed quarantine inspection, are healthy and disease-free, and breed with Duroc to produce ternary hybrid pigs. Encourage farmers to breed ternary hybrid pigs by themselves, try to avoid buying piglets in the market, and beware of bringing diseases into pigs, polluting pens and affecting breeding benefits. \x0d\ III。 Feed quality \ When buying full-price feed, you should choose brand feed with moderate price, qualified quality, reliability and certain popularity, and don't buy inferior brand feed with no quality guarantee for cheap, and shoddy it. If you just want to get a cheap price and buy feed at a very low price, it will often be counterproductive. Just like the fake milk powder incident, the lack of nutrition of inferior raw materials will directly affect the growth and development of pigs, affect their health, reduce their disease resistance and lead to diseases in pigs. \x0d\ When you make your own food, you must strictly control the raw materials. Moldy corn and soybeans must be treated with mildew remover before use. If the moldy feed is fed directly, it will cause diarrhea and stop growth, and the severe one will die and the pregnant sow will miscarry. In the second half of 2003, due to continuous rainfall, most of the corn in our city was mildewed. A pig farm in Funan county feeds sows with moldy corn, and the abortion rate of sows is as high as 30%. After stopping feeding moldy corn, the number of miscarriages decreased significantly. \x0d\ IV。 Standardize epidemic prevention \x0d\ Pigs must do a good job in epidemic prevention, and the pens should be disinfected regularly 2-3 times a week. With the growth of piglets' age, they should be vaccinated regularly and on time. Pay attention to the preservation conditions and the validity period of the vaccine when buying the vaccine. Before vaccination, it is necessary to check whether the vacuum degree of the vaccine has been destroyed, and find out the theoretical injection amount and empirical injection amount of the vaccine. In recent years, the increase of epidemic diseases has accelerated, and the types of vaccines that need to be injected are also increasing. According to the requirements of the latest immunization program for swine diseases, vaccines above 10 must be injected. Vaccination is the most labor-saving, cost-saving, effective and cost-effective epidemic prevention measure to prevent infectious diseases in pigs. Some pig farmers are afraid of wasting time and money, while others don't get vaccinated. What's more, they are afraid of spending money and don't take any vaccines. This kind of pig-raising method of resignation is very dangerous. Although the newly-built pigsty may be able to raise one or two batches of pigs, if one batch of pigs is infected, it may not be enough to compensate all the money earned by the first two batches. Pig farmers should carefully calculate their accounts. Is it cost-effective to get vaccinated or not to get vaccinated when you are sick? A pig fattens for several months and earns more than RMB 100. If you stop growing once you get sick, eat feed for a few days and spend a lot of medicine. Even if you can cure pigs, you won't make much money. Therefore, vaccination and epidemic prevention are also the key links for raising pigs to make money. \x0d\ 5。 Scientific management \x0d\ 1. Buy piglets, fatten themselves up. At present, there are many pig diseases. I bought a pig from the market and accidentally took it home. The disease will not only affect the newly bought pigs, but also infect the original pigs. According to a pig farmer in Linquan County, he bought 289 piglets from outside the province at one time and returned to his hometown in a few days. None of these 289 piglets died of illness. Therefore, we advocate that raising sows, piglets and fattening pigs at home is the safest and the best economic benefit. \x0d\ 2。 Appropriately expand the scale of pig raising. Raising a pig is raising, raising 10 pigs is also raising, and raising 10 fattening pigs is also raising, so there is no need to increase the number of breeders. Raising 1 pig can only earn 100 yuan, raising 100 pigs can earn 1000 yuan, and raising 100 pigs can earn 100 yuan, which is at least equivalent to the income from going out to work. When it comes to raising 100 pigs, it is actually very simple, as long as raising 5-6 binary sows is enough. Therefore, it is suggested that the majority of farmers appropriately expand the scale of breeding and change sideline business into the main business. \x0d\ 3。 Make good use of the season and the price difference. The growth rate of pigs is closely related to the environmental temperature. Fattening pigs grow fastest at 10-20℃, so pigs grow faster in spring and autumn, followed by winter, and gain the slowest weight in summer. The feed they eat turns into sweat, and the effect is very poor. Therefore, conditional pig farms should burn boilers to warm pigs in winter and install fans to cool pigs in summer. Pig prices may be higher during the Dragon Boat Festival, Mid-Autumn Festival and Spring Festival in May. When arranging sow breeding, taking into account the slaughter time and price factors of fat pigs, the benefit of raising pigs will be better.
