Pork is an indispensable meat product in our daily life. At the same time, my country is also a big pork consumer. The demand for pork in the market has always been quite stable. In the past two years, the price of pork has soared, and the pig raising market has ushered in a favorable situation. Many people have joined the pig raising army and want to share the cake. However, in order to ensure good economic benefits, it is necessary to start with basic feeding and management. Now I will share the pig breeding technology with you.
1. The main points of breeding boars
1）. In the process of raising breeding boars, the main goal is to improve the breeding ability of the breeding boars so that they can play a better role in the process of piglet breeding. Breeding boars are mainly fed with concentrate, with more than 3 kinds of feeds including coarse, fine and green. In peak breeding season, high protein feed such as beans and eggs should be added to improve breeding ability and semen quality. And when the weather is cold, you can add some more seasoning.
2）. It is best to control the body weight of the boar to be neither fat nor thin. If it is too fat, it will affect the libido, which will affect the breeding process; if it is too thin, it means that the impact is not good, and if it is serious, it will threaten the normal growth of the boar. development.
3）. Generally speaking, boars should ensure a daily amount of exercise of 800 to 1000 meters, and exercise should be carried out half an hour after the boars eat. When the boar pen is built, a single pig is built, and the sports field is designed to be slightly larger.
4）. Check the semen quality 3 times a month, mainly check the density and vitality of sperm. In particular, semen quality must be checked before a gilt is used or before an adult boar is transferred from a non-breeding period to a breeding period. If artificially inseminated boars are used, the semen quality should be checked every time the semen is collected.
2. Main points of breeding sows
1）. When breeding sows, three meals a day should be fed regularly and quantitatively. The daily concentrate of breeding sows should be kept at about 2.5 kg, which is basically the same as that of breeding boars in winter, and in summer Also add some green fodder to the feed to ensure nutritional balance.
2）. When the body weight is about 50 kg, the material should be properly controlled, and the body fat should not be too fat. When the body weight is about 70 kg, inject parvovirus and Japanese encephalitis vaccine (repeated after 15 days), and pay attention to the estrus performance of the sow. . The year, month, and day of the first estrus of the sow are recorded in detail to calculate the next estrus for breeding.
3）. For the breeding of sows, try to choose in the morning, evening or when the weather is cool, and repeat the breeding for 12 hours. If the sow did not come into estrus 21 days after mating, the sow was transferred to gestational feeding.
4）. Pay attention to the clinical signs of the sow. Once the sow is sick during pregnancy, special attention should be paid to the use of medicines. Medicines that may cause abortion must not be used. In addition, if it is summer, it is necessary to do a good job of preventing heatstroke and cooling; if it is winter, pay attention to keeping warm and prevent cold, and the sows will enter a thoroughly sterilized farrowing room one week before giving birth, and prepare relevant delivery supplies.
3. Feeding points of piglets
1）. When the piglets are born, temperature control is very important. Try to control the temperature of the delivery room above 20 degrees, especially in winter, because the outdoor temperature is low, you should try to ensure that the temperature is consistent with the temperature of the breeding room. Avoid catching a cold due to incompatibility with the temperature.
2）. In 2-3 days after the birth of the piglets, the method of helping the weak and suppressing the strong should be adopted manually, so that the piglets can suck the fixed teats, and try to fix the weak piglets on the first few pairs of teats, so that the piglets can grow evenly and robustly.
3）. Drinking water should be supplemented from the age of 3-5 days, and water containing 0.8% hydrochloric acid should be used for the age of 3-20 days. After 20 days of age, use clear water to supplement the incomplete secretion of gastric juice and digest pepsin. Weaning weight. Feeding attention should be paid to the supplementation of iron, selenium, water and feed. Generally, feed is started at 7 days of age. The method is to put a small amount of feed on a dry and clean wooden board, and then change it into the feed trough after starting to eat. When starting feeding, be sure to feed 4-6 times a day according to the principle of "feed less and add more often".
4）. Weaning time should be well controlled, generally at 35-45 days of age, when the body weight reaches 4-5kg or more, weaning is the most suitable. Prolonged lactation period will affect the annual number of litters and the number of piglets produced.
In general, pig farmers should distinguish between different situations and different growth stages, and choose feeding and management techniques reasonably, so as to ensure the healthy growth of live pigs.
