A great summary of experience in the process of raising pigs

1. About biting tail

The author raised more than 30 sows, pig more than ten years, the following is my breeding process summarized in a few small ways, now take out, share with you, hope to have this trouble pig friends help. As we all know, even if a pig has its tail cut off, it will bite its tail from time to time. My method: asphalt appropriate reserve, diesel appropriate reserve, crushed pepper powder appropriate reserve. Put asphalt in a container, bake it over fire, mix it with diesel oil and pepper powder, dip the mixture into the tail of the bitten pig before the asphalt has solidified, so that the smell of diesel oil and the spicy taste of pepper will make the tail of the bitten pig sigh.

II. About sow and column This method is suitable for pig friends who are used in emergency circles First, weave a pig-mouth-shaped halter with thin iron wire and No.8 lead wire for standby. Drive the two sows to be circled into a circle. After the strong and weak are separated (this is the key), put the halter prepared in advance on the mouth of the strong one and fix it well. In this way, it will not bite another pig, and it will constantly shake its head and rub on the ground without time to bite again. This method is suitable for pigs who are not in a hurry Separate a large circle with an iron fence in the middle (this is the key), and drive the two sows to be circled into two small circles with iron fences in the middle, so that after they are familiar with each other for 4-5 days, they will not bite or quarrel like old acquaintances. I have a "solidarity circle."

III. Cleaned pigsty ground after pig slaughter After the fat pig is released, the thick layer of dung on the ground of the empty house is the most troublesome (the pig friends who wash the circle with water every day and the fattening house may not have this problem), sometimes a house will make you grin and sweat. My practice is: 1-2 days before the pig is released, splash water on the ground of the pigsty, then put some balls, empty drink bottles and other things to play with, use the pig's desire to explore, let them compete for toys, plus trample, arch and water infiltration (if the dung is too thick, splash several times), the dung on the ground will soon be made up, and then use a flat shovel to remove it. This saves time and effort. You may wish to try it.

Four, a little about the treatment of post-weaning piglets suddenly appear cerebral nerve symptoms small experience After weaning piglets, sometimes appear sudden quadriplegia, pumping and other symptoms, for such neurological symptoms of pigs, in the field judgment is not too good to determine pseudorabies, streptococcus, edema, listeria disease and other diseases that can cause neurological symptoms, can only be treated with drugs according to experience. Common treatment is symptomatic treatment: sulfadiazine sodium, diclofenac, amikacin, pefloxacin mesylate, etc., treatment effect is general, mortality is very high. In my practice, for pigs with neurological symptoms that are not easy to distinguish what causes them, anti-inflammatory treatment with antibiotics, the formula is: ceftriaxone sodium 10 mg/kg body weight + astragalus polysaccharide 0.2 ml/kg body weight + dexamethasone 5 mg (human use 1 ml 5 mg), injection once, generally 6~12 hours to improve or recover and healthy pigs, and then the next day more than one injection of drugs for drug maintenance. Try this treatment until you find something more effective.

5. Sows give birth during the day Many sows give birth at night, which brings a lot of inconvenience to management. Cloprostenol sodium can achieve the goal of simultaneous delivery, but when and where to inject it is a critical issue. Prostenol sodium instructions say intramuscular injection, injection time is not stated, but practice has proved that the effect is not ideal, according to my practice, injection time master at 6 pm, injection site selection pig vaginal subcutaneous injection effect is best, 98% can be delivered the next day! Self-calculated time, generally 20 hours after the injection to give birth. Injection site: sow vulva side, dosage 1 ml (this site can reduce the dosage) and quick effect.

6. Causes affecting semen quality From make artificial insemination there know: boar in the occurrence of febrile diseases, generally within a month it is best not to breed, because boar fever within a month after the sperm activity of less than 30%. It has something to do with semen maturation. About eight weeks.

Seven, piglets start diarrhea three days after birth Piglets start diarrhea three days after birth, yellow and watery, and a litter dies within a week. With piglets over milk spirit bacteria net sulfate colistin framycinin wear Hu Ning and other antidiarrheal drugs, ineffective. Listen to friends say: prenatal 20-30 days, sow injection 50 doses of swine fever vaccine immunity, effective. With the intention of giving it a try, I gave 50 doses of swine fever vaccine to sows 20 days before birth and diluted it with 1 vial of levamisole of 10 ml. As a result, the piglets produced were no longer diarrhea and the mortality rate was very low.

Eight, fat pig injection We have asked the following pigs to be held up when they are injected, and the reserve pigs to be restrained when they are injected, but how can the fattening pigs in the middle stage be injected to ensure the injection effect and save time? It is unrealistic to fix fattening pigs like reserve pigs, because too many of them will cost too much work, and if the needle is shot, it will often make some pigs fail or the effect is not ideal, so it is necessary to find an operable method. In production, we deal with it like this: in a small circle, several breeders squeeze the pigs to a corner or edge with an iron railing, because the pigs are not easy to move when crowded together, especially the pig heads have to be lifted, it is easy to fix the injection; larger nursery pigs can also be operated in this way.

IX. Feeding for suckling pigs The book has been emphasizing the benefits of piglet feeding during lactation, but it often occurs that piglets still do not eat after weaning, resulting in severe weaning diarrhea and fat loss. This is because the feeding at piglet stage is not in place. We summarize the following feeding methods for reference: 1. Pebble method: Put a few clean pebbles in the piglet feeding trough. Piglets are interested in foreign bodies because of their exploratory behavior. They will arch pebbles and unconsciously eat feed; In finding pebbles is not easy pig farms, but also useful washed penicillin bottles instead of, but also have a certain effect. 2. Bottle hanging method: hang a plastic bottle of special color above the feeding trough. When the pig arches the bottle, it will smell the smell of feed and produce the desire to feed. 3, smearing method: to pig mouth smearing, is the best effect of the existing method; smearing the simplest way is, in the pig sleep, the breeder gently walk over, one hand will open the pig mouth, the other hand dipped in the paste into the pig mouth; smearing, do not have to wipe all the pigs, a nest of two to three can be smeared, and do not wake up the pig; this operation does not take a lot of time, easy for the breeder to accept.
