Piglet diarrhea is a large infectious disease in the pig breeding industry. Its high incidence rate, rapid transmission rate and high mortality rate seriously endanger the development and economic benefits of the pig breeding industry. So why is there a large area of ​​piglet diarrhea? How to prevent piglet diarrhea? Let's take a look at the causes and prevention measures of piglet diarrhea.
First, piglet diarrhea is generally caused by these reasons
1. Piglets lack congenital immunity leading to diarrhea in piglets.
2. The function of piglets to regulate body temperature is not perfect, the resistance to cold is poor, and it is easy to get sick and lead to diarrhea.
3. Large-scale pig farm piglets early weaning comprehensive stress is too strong to promote disease, leading to piglet diarrhea.
4. Improper nutrition and feeding management.
5. Piglet diarrhea caused by bacterial pathogens and viral causes.
Second, the clinical characteristics of piglet diarrhea
Piglet diarrhea is a syndrome of multiple etiological mechanisms. There are many causes of diarrhea in piglets. The more common ones are bacteria, viruses, nutritional imbalances and adverse stress. Among these common causes of illness, no matter which primary disease, it may lead to decreased immunity, physiological and metabolic disorders, and concurrent or secondary infection. This type of livestock disease is the most serious hazard to young piglets from 1 to 15 days, with a mortality rate of more than 50%.
The typical symptoms of piglet diarrhea are that once the disease occurs, it will show varying degrees of diarrhea or diarrhea, and the piglet body will also appear pale, anemia or dehydration. Vomiting can also occur in sick pigs. Individual piglets die rapidly in acute cases, but most will turn from acute to chronic, consumptive conditions.
Third, the prevention and treatment technology of piglet diarrhea
1. Prevention and treatment of diarrhea caused by indigestion
For piglet diarrhea with indigestion, effective preventive measures can usually reduce the incidence of disease. Specifically, we can start the corresponding prevention work from the following aspects. First, to strengthen the breeding and management of pregnant sows, which usually produce piglets with strong constitution and relatively strong resistance. Second, do a good job of daily heat preservation for piglets. The most basic thing should be to keep the interior of the pig house dry. Third, do a good job in postpartum maintenance of sows, especially to help piglets eat colostrum, which is usually effective in preventing diarrhea. Fourth, the piglet should be properly fed early seven days after birth, which will help the piglet's gastrointestinal digestive system slowly adapt to the plant feed before weaning, and it is conducive to smooth weaning. Smooth transition, but also can effectively prevent diarrhea in piglets. If the piglet does not have diarrhea soon after birth, you can add a compound enzyme preparation (such as lactase, protease, whole intestinal and other preparations) to the feed. At the same time, feed the piglet in the morning and evening. Since the dying of dysentery, the dose is usually 50 grams per 10 piglets.
2. Prevention and treatment of diarrhea caused by pig rotavirus infection
The diarrhea caused by rotavirus is the highest incidence of diarrhea in piglets that occur between 1 and 8 weeks of age, especially in piglets from 10 days to 28 days old. The stools caused by the diarrhea caused by this virus usually appear dark gray, yellow or grayish white, and piglets are prone to weight loss or dehydration, and occasionally accompanied by vomiting. The method for whole group prevention and control of this disease is as follows: "Yellow polysaccharide (original powder, granule) + ammonium sulphate soluble powder" mixture or mixed drink, two doses per day, feeding in the morning and evening Once, feed for three to five consecutive days. For the treatment of heavier onset, the following measures can be taken: “Huang's polysaccharide or Shuanghuanglian injection 0.2ml/kg + ceftiofur sodium or ampicillin sodium 0.05 to 0.1g/kg for mixed intramuscular injection, and also the other side neck Intramuscular injection of VB injection, one dose per day, injection for 2 days to 3 days, during the injection treatment can also be used in conjunction with the whole group of prevention and treatment agents, while at the same time should also strengthen feeding management until the sick pigs heal.
3. Prevention and treatment of iron deficiency diarrhea
The diarrhea of ​​this type of piglet is mainly caused by diarrhea caused by insufficient iron in the piglet body or severe iron deficiency. In the first few weeks after the birth of the piglets, the growth and development is very fast, and the whole blood volume is growing at a very fast rate. Therefore, the demand for iron is relatively large, but the supply of iron in breast milk is very limited, or in winter. In the cold spring season, piglets are grown on wooden boards or on concrete floors. If piglets are not added to soil, supplemented with iron or feed, some piglets will develop diarrhea due to iron deficiency. The diarrhea caused by this factor usually manifests as the following symptoms, lack of energy, skin folds, breastfeeding behind other individuals, and the appetite of piglets is greatly reduced. Some of the piglets also have slight jaundice and are gray or brown. Some porridges have intermittent dysentery. Some piglets show a bowel movement, but only a small amount of loose stools. Some sick pigs show difficulty breathing, asthma or body or The edema of the head is getting thinner and the growth and development become extremely slow.
4. Prevention and treatment of diarrhea caused by parasitic diseases
For the diarrhea caused by such causes, the following methods can usually be used for prevention and treatment. For each kilogram of body weight, 8 mg of levozole and 5-10 mg of albendazole are mixed and mixed into feed or drinking water for administration. Alternatively, the piglet can be administered subcutaneously with ivermectin at a dose of 300 ug per kilogram of body weight, and then repeated injections every 4 to 5 days, which is even better. In the daily life, attention should also be paid to the prenatal and postpartum management of pregnant pigs. For pregnant sows, they can be dewormed in the middle of pregnancy, and the sows are thoroughly washed with hot water and soap before the labor to remove the body. Ascaris eggs.
5. Strengthen daily management and reduce the incidence of various stress reactions
As far as the piglets themselves are concerned, their own neuromodulation and thermoregulatory functions are not perfect, and the stimulating adaptability to various types of stress factors is relatively poor. These characteristics can easily lead to digestive function in piglets. Disorders, which in turn lead to diarrhea. In view of this situation, it is necessary to maintain the temperature and humidity of the air around the piglets in the pig house to avoid a sudden rise or fall of the room temperature. At the same time, the sanitation of the environment around the piglets should be done properly, and the interior should be cleaned. dry. Also, when weaning piglets, we should adopt a step-by-step weaning method. For example, we can isolate them from the sows during the day, merge the piglets with the mothers at night, and then slowly go to the mothers. Regular feeding times and methods should be maintained before weaning, and the feeding of piglets should be carried out step by step. These practices are beneficial to reduce all kinds of stress reactions in piglet diarrhea and prevent piglet diarrhea.
I will introduce this to you about the piglet diarrhea. For piglet diarrhea, in fact, the sanitation of the pig house has a great relationship, so the pig house is clean and scientific, and scientific feeding is an important means of preventing disease.
