Key points of raising piglets in spring

Sows are mated and conceived from October to November, and the piglets from February to March next year are called spring piglets, and in some places they are also called December piglets. Better economic benefits can be obtained by choosing to raise spring piglets. Because the conception rate of sows is high from October to November, the external temperature is low in the later stage of pregnancy, the appetite of sows is strong, the embryos can get rich nutrition, and the weight and survival rate of piglets are very high. In addition, due to the strong appetite of sows, more milk, good milk quality, strong development of piglets, significant weaning body, corresponding weight gain is also fast, and the fencing rate is higher.

However, the outside world is colder in spring, the temperature in the pigsty is lower, and the feed of piglets is changed after weaning, and the feeding site is changed rapidly. if the feeding management is not good, not only can not get a better benefit, but also lose fat. it directly affects the fattening rate and feed utilization rate.

So, how to raise spring piglets?

First, prepare the barracks. Piglets repair the barn before entering the fence, so that there is no leaking rain and no stagnant water. And clean the original feces and bedding grass in the column, and the cleaned dirt should be picked to the place far away from the fence house to accumulate and ferment. Then use 20% quicklime solution to whitewash and disinfect the walls, fences, food troughs, floors and other places.

Second, it is necessary to do a good job in the training of piglets to keep the pigsty clean and hygienic. After entering the pen, the piglets should be trained to defecate and defecate in one place, which can keep the pigsty floor and pig body dry and clean, promote its growth and reduce disease. The training method is: clean and rinse the pigsty before entering the pig, put some feces in the corner where you are required to defecate and pour some water, spread some accumulated grass in the sleeping place, put some feed in the feeding place, and then lock up the piglets. After entering the pen, the piglets smell different smells and automatically run to the designated corner to defecate. If a small number of pigs randomly pull feces, drive them away when they find them, and sweep them away if they have, especially after feeding and getting up early in the morning, so that pigs will form a habit a few days later.

Third, it is necessary to strengthen feeding and management. The piglets bought are full of a fine and rich meal of feed, and after a struggle, their health is poor, and digestive system disorders often occur. In order to make the pig return to normal in time, on the day of buying the pig, wait for the pig to rest in the pen for half an hour, spray appropriate amount of liquor on the pig, rub with grass, make the pig comfortable qi and blood, restore fatigue. Then feed some warm rice washing water mixed with an appropriate amount of mirabilite, and then feed some green vegetables to prevent gastrointestinal indigestion. The next day, after the pig is excreted and accumulated, it can be fed with an appropriate amount of malt and wine koji to aid digestion, and can also be fed with some concentrate to supplement nutrition and strengthen the physique. The feed should be changed gradually and the quality should be stable. The first month should be as similar as possible before weaning, without sudden changes, and the dietary protein level should be maintained at about 15%-16%. If conditions permit, some raw juice feeds such as soybean milk and powder milk can be fed appropriately, which is very good for growth and development. It will be changed into shelf pig feed after a month. The times of feeding should be from more to less, the number of times of feeding should be more in the first half of the month, the interval should not be too long, and night feed should be fed once at night. With the increase of age, the number of feeding can be gradually reduced, and three times a day will be fine after a month.

Fourth, we should strengthen the prevention and control of epidemic diseases. The epidemic disease of pigs is the archenemy of the industry. Strict control of the epidemic is the key to ensuring the prosperity of pig farming. According to the current conditions in rural areas, first of all, it is necessary to make a good entrance to pigs, strictly check their health, and do not buy sick pigs. The newly bought pigs should be kept in isolation from the original pigs for more than half a month before they can be merged. Swine fever, swine erysipelas, swine lung disease, streptococcosis and other vaccines should be injected in time. Agricultural products with conditions had better be self-propagated and self-sustaining. At the same time, to achieve captive breeding, hogwash feeding pigs should be boiled, do not go to the market to buy dead pork to eat, in order to prevent the spread of epidemic disease. The second is to achieve regular deworming, from piglets into the pen to fat pigs out of the pen to regularly do preventive deworming 2 or 3 times. There are many drugs to dispel parasites in pigs, commonly used are levamisole hydrochloride tablets, which are administered at a dose of 20 to 30 milligrams per kilogram of body weight, or animal refined trichlorfon, mixed with a small amount of pig food at a dose of 0.1 grams per kilogram of body weight.
