Piglets have weak vitality and often suffer from diarrhea, which makes many farmers suffer from headaches. The following is a brief analysis of the causes and prevention methods of piglet diarrhea. So that all farmers can use the disease.

First, the cause of the disease

Diarrhea in piglets is a symptom. There are many causes of the disease. There are dyspepsia-like diarrhea caused by feeding management, infectious diarrhea caused by various infectious diseases, toxic diarrhea and parasitic diarrhea.

1. Poor feeding management.

(1) Improper management of sows. Improper management of sows causes breast milk to be deficient in piglets, or indigestion after eating too much milk in piglets, lack of timely feeding of colostrum or insufficient colostrum, poor disinfection of breasts in pens or litter, and insulation measures Inadequate, failing to supplement trace elements such as iron and selenium as required, feeding is not timely or the feed quality is poor, there is not enough clean drinking water, and improper weaning measures cause stress;

(2) Poor piglets are poorly managed. Did not eat enough colostrum, winter insulation and summer heatstroke measures are not good, the house air pollution, poor disinfection, damp house, poor feed quality, feed can not be quantitative.

2. Immunity is weak, infectious diseases are invading.

The pathogenic microorganisms causing piglet diarrhea include Escherichia coli (piglet jaundice, piglet white peony), Clostridium perfringens (piglet red carp), piglet paratyphoid fever, swine fever, porcine transmissible gastroenteritis, epidemic diarrhea, round Virus and so on. In general, diarrhea in piglets, regardless of the cause, is accompanied by or following infection with the pathogenic organism. The infection and treatment of pathogenic microorganisms are affected by feeding management, environmental factors and the body's ability to resist disease.

3. Feeding mycotoxins causes diarrhea in piglets.

There is also infection with intestinal coccidia causing diarrhea in piglets. There are also factors such as temperature stress that cause diarrhea.

Second, prevention measures

Treatment due to illness, symptomatic treatment, different causes of piglet diarrhea, different methods should be used.

1. Strengthen feeding management.

(1) Grasp the management of piglets. During the piglet rearing process, there are three peak periods of diarrhea, namely: 1 to 7 days after birth, 14 to 21 days, and 7 days after weaning. It is important to do a good job of "born birth" maintenance; (2) to ensure that piglets eat colostrum in time. Colostrum refers to the emulsion secreted by the sow within one week after the birth of the piglet. It is rich in nutrients and any other substances that are difficult to replace. Therefore, after the piglet is born, clean the oral mucus with clean gauze or towel, and fix the nipple as soon as possible. , let it eat enough colostrum; (3) to ensure that the housing is clean. The pens should be well ventilated and have good sanitary conditions; (4) Highly valued heat preservation and heatstroke prevention. Piglets have higher temperature requirements. Piglets from 15 to 30 days old should ensure that the house is in the range of 25 ° C ~ 30 ° C in winter and winter; (5) Ensure that the drinking water is clean enough; (6) Strictly control the pigs. The imported piglets must be strictly quarantined to ensure that they are healthy and disease-free. (7) Implement a system of all-in, all-out. In order to prevent cross-infection, it is necessary to implement a full-in, all-out system to strictly disinfect the pens; (8) timely isolation of sick pigs; (9) to ensure the time and quality of feed for piglets.

2. Grasp the management of sow feeding.

Before the sow enters the larvae, the bed is disinfected with 2% caustic soda; the sow is used for postpartum and postpartum, and the sow's breast, abdomen and vulva are scrubbed with warm 0.1% potassium permanganate; before the piglet eats colostrum, 2~3 drops of milk before nipples are squeezed out; sows are reduced by 7 days before birth, 0.5kg per day, no feeding at birth, limited feeding after delivery, and gradually added to normal feeding 7 days after delivery; feeding sows It is rich in nutrients, good in palatability, easy to digest and absorb, can promote high quality feed for lactation, and ensure clean drinking water; conditional feeding of high quality green and green feed has a good effect on sow production; timely and effective prevention and treatment of sows postpartum fever, no Food, no milk, breast inflammation and other diseases.

3. Strengthen disinfection and deworming measures.

Piglets are extremely sensitive to environmental hygiene. Therefore, during the growth of piglets, the sows delivery room, piglet pens, sow nipples, feeding troughs, pedestrians and pedestrians should be strictly disinfected. The door is usually made of 1% caustic soda. Solution disinfection, housing and environment also need to be disinfected, sow belly and 0.1% potassium permanganate disinfection. Regular deworming: Piglets should be routinely eliminated from flies, mice and other pests while weeding and deworming before weaning and transfer.

4. Establish a scientific immunization system.

Since the type of diarrhea caused by infection is high, and the fundamental measure of infectious diseases is prevention, it is very important to establish a scientific and standardized immunization system. (1) Sow immunization. According to the specific conditions and characteristics of the farmer or pig farm, the sows can concentrate on swine fever, pig foot and mouth disease 2~3 times a year, pregnant sows 45 days before the pig pseudorabies vaccine, and 35 days before the birth. Gastrointestinal gastroenteritis, epidemic diarrhea, rotavirus triple vaccine, multivalent vaccine of E. coli 25 days before birth, circovirus vaccine 20 days before birth; (2) immunization of piglets. Piglets were injected with circovirus vaccine at 15 days of age, swine fever vaccine at 25 days of age, and piglet paratyphoid vaccine at 35 days of age. It is important to emphasize here that since sows have been injected with several vaccines before birth, the interference of “maternal antibody” should be considered in the injection of vaccines for piglets, and scientific and rational immunization procedures should be established.

Third, drug treatment

1. Fight against pathogenic microorganisms or prevent secondary infections.

Gentamicin 1~15,000 units/kg, intramuscular injection, 2 times/d; or quinolones 3~5 ml/kg, intramuscular or intravenous injection; oral administration of poplar flower oral solution, Houhai injection of berberine, Sulfonamides, florfenicol, oxytetracycline, etc. can be used.

2. Symptomatic treatment, regulating physiological functions.

5% glucose normal saline 200~300 ml, 5% sodium bicarbonate 30~50 ml, VC 0.2~0.5 g, VB 0.02~0.05 g, intravenous or intraperitoneal injection after mixing; or rehydration salt per kilogram of drinking water (per 1 000 g contains 750 g of glucose, 100 g of sodium carbonate, 5 g of potassium chloride) 30 g, allowing free drinking water until the symptoms disappear. When severe dehydration occurs, 10~20 g of activated carbon or 2~5 g of bismuth nitrite can be used. It can also be used for phlegm and stasis. Because diarrhea is not conducive to the discharge of toxins, in actual practice, do not easily use antidiarrheal drugs when it is not necessary.

3. Chinese medicine decoction and acupoint injection therapy.

(1) Rice shell therapy. 20 g rice shell with water 200 ml, boiled with a fire, then simmer the liquid to 100 ml. Double-layer gauze is packed in a 250 ml glucose bottle, and a 16-gauge needle is used to puncture the rubber stopper. The glucose bottle of the traditional Chinese medicine solution is cooked in a domestic pressure cooker for 10 minutes to be taken out for cooling. Usage and Dosage: After the piglet is 0.5 ml per kilogram of body weight, it is usually injected once. It is repeated once a day, and it will not be relapsed (no overdose and repeated use).

(2) Chinese medicine decoction corn therapy. For refractory swine diarrhea (such as Escherichia coli diarrhea), whether it is intramuscular, intravenous or acupoint injection, due to the number of sick pigs, the injection is time-consuming and extremely troublesome, the Chinese medicine fried corn kernels can be used to feed the piglets. Composition of traditional Chinese medicine: It can be added or subtracted with "Umei San": ebony, dried persimmon, berberine, turmeric, rice shell, etc., feces with bloody pus and pulsatilla, mantle; feces are clear water-like Jiamutong, Alisma; common body temperature Elevated sage mother, raw gypsum (not decocted and then mixed with corn); winter stomach diarrhea plus ginger, brown sugar, white wine (not decocted); summer can be added with garlic (the amount of each drug depends on the number of sick pigs on the farm) As appropriate,). It can also be added or subtracted with “Qianjin Zhixie San”. Decoction method: Weigh the selected drugs, and then weigh 10 times the corn kernels, put them in a stainless steel pot of appropriate size, add the medicine and the water twice the volume of the corn kernels, stir fry until the medicine and water, etc. When the amount is reduced, simmer until the water is boiled (when the active ingredients of the drug are mostly mixed with corn kernels), and wait for the temperature to be spared. How to use: To prevent sick pigs from fasting for 12~18 hours (to make the sick pigs have strong hunger), mix the drugs that are not easy to be boiled and then mix with the boiled corn kernels and dregs, together with Dregs and corn are scattered on a small amount of feed tanks or clean cement pots on the ground to allow them to eat ad libitum. (It is strictly forbidden to over-spray too much, which causes waste and makes piglets lack hunger and affects feed intake). 4 hours after the piglets were fed with the drug corn kernels, the sink was placed in 0.5% saline to make it free to drink. After 2 hours, the sink was put into 1% baking soda to drink, generally effective once, and the same method was used on the next day. Once again, the cure rate is over 95%.

(3) Bran vinegar liquor therapy. Weigh 1 000 g of bran, and slightly brown with the braised bran in the iron pan. Add 100 ml of vinegar and 50 ml of white wine, stir well, and cool for a while. Usage: 50-100 g per sick piglet, once a day, usually cured twice.

(4) Amaranth persimmon therapy. 1 000 g of amaranth, raw persimmon (green persimmon) chopped into a mud, 50 g per serving, 1 time / d, usually 1 or 2 times can cure indigestion diarrhea.

(5) Garlic charcoal therapy. Garlic 500 g island city garlic mud plus charcoal powder 10 g, baking soda 20 g, stir evenly, 50~100 g per serving orally, it has a miraculous effect on piglet white peony.

Fourth, Chinese medicine prevention

Hawthorn, malt and Divine are mixed in a ratio of 1:1:0.6. The piglets are 10~15 g per day for preventive use. They have the effect of increasing feed intake, helping digestion, promoting growth and preventing diarrhea. When treating medication, add Pulsatilla, Rhizoma Coptidis, Radix Astragali, Rhubarb, Psyllium, Fried Rice, etc. The dosage of each drug is 5~10 g per piglet per day for 2~4 days.

There are many reasons for piglet diarrhea, such as improper feeding or other viral infections. If you want to reduce the incidence of piglet diarrhea, then you need to prevent it in advance. The above is about the prevention and prevention of piglet diarrhea. Remember to collect it.
