Lamb dysentery is a diarrheal disease caused by a newly born lamb infected with a bacterium called Clostridium welchii B. The dysentery of lamb can cause a large number of newborn lambs to die, which is an infectious disease that is very harmful to the growth of lambs.

How does the Lamb's dysentery spread popular? How can we diagnose it? Let's take a look at the Xiaonong.com.

First, how is the spread of lamb dysentery:

Lamb dysentery is caused by bacterial infections. Clostridium perfringens type B, which causes diarrhea in lambs, is a common bacterium that is widely distributed in all corners of sheep farms, such as sheep penins, ground, drinking water, feeding utensils or feed. Even in the body of a sheep, there are such bacteria.

Lamb dysentery is mainly infected through the digestive tract. If the environment is not strictly disinfected, the bacteria on the walls, the ground and the utensils will adhere to the ewes of the ewes. When the lambs are breastfeeding, the bacteria on the nipples will be eaten into the body, causing infection; In addition, the umbilical cord of the newborn lamb, the hand of the delivery staff, clothes, etc. may become the way for the lamb to infect bacteria.

Lambs are prone to lamb dysentery within 7 days of birth, especially 2-3 days old. It is a high incidence of this disease. Because the digestive system of the newly born lamb is still not perfect, it is difficult to produce strong resistance to bacteria. Therefore, infection is very likely to occur once exposed to bacteria. As the lamb grows, it is generally more than 7 days old, and the disease rarely occurs in lambs.

In addition, from the lamb itself, because it has just been born, it is greatly affected by the environment, climate, and feeding management. If it is stimulated by stress factors, such as poor insulation, the lamb is frozen, and the lamb is not enough. It will lead to a decrease in the body's resistance to the lamb and cause the lamb to suffer from diarrhea.

Second, the diagnosis of lamb dysentery is:

The obvious symptom of the sick lamb is diarrhea. The severity of diarrhea is related to the severity of the lamb. The discharged feces are sometimes as thin as water, sometimes bloody (read xue), sometimes like batter, with foul smell, and the state of feces Sheep vary from person to person.

Under normal circumstances, the sick lamb is accompanied by symptoms of loss of appetite and loss of appetite; the abdomen with severe illness appears to be inflated, bowing due to abdominal pain.

Diagnosis can be based on the age of the lambs within 7 days, the characteristics of multiple occurrences within 2 to 3 days after birth, combined with the above mentioned symptoms, can consider the disease of lamb dysentery, in order to accurately diagnose, you need to contact A veterinarian or a specialized veterinary diagnostic department will conduct further inspections.

Third, the prevention and treatment of lamb dysentery:

Lamb dysentery is rapid, and death is fast. Some may die within 1-2 days after the onset of the disease. Therefore, the above symptoms should be diagnosed immediately, and timely treatment should be taken to avoid delaying the disease. After finishing the diagnosis, let's look at how to prevent this disease. The following small series of Huinong.com will introduce the lamb dysentery. How should we prevent it? What effective measures are there?

In production, we must conscientiously follow the principle of “winning the defense and preventing the disease”. Therefore, we must first do a good job in feeding management and preventive work. Under normal circumstances, we can refer to the following aspects to prevent this disease:

First, do a good job of the ewe's grievances.

Everyone knows that the ewe can give birth to a strong and strong sheep baby, so it is necessary to strengthen the physique of the pregnant ewes. Grazing sheep should feed the pregnant ewes properly when the pasture is not good; the feeding of the sheep should be reasonable, especially in the late pregnancy, it should be fed with high-quality feed rich in protein, fat, minerals and vitamins. Forage, especially in the ewes before and after delivery, should be fed with high quality forage.

Second, do the disinfection of the delivery room

Whether it is delivery or caesarean section, the floor, walls and utensils of the delivery room should be strictly disinfected before use. There are many disinfection methods. The sheep farm can choose the corresponding disinfection drugs and disinfection methods according to their actual conditions. If the caesarean section is performed, the surgeons should do the corresponding sanitation and disinfection work.

Third, do a good job in the management of the newborn lamb.

The lambs have a poor body temperature regulation ability. Therefore, after the lamb is born, the lamb should be kept cold and kept warm. In addition, the lamb should be given colostrum as soon as possible. The colostrum should be controlled within 1 hour, and the lamb should be guaranteed. Full, for lambs with weak constitution, a small number of feeding methods should be adopted.

If the lamb does not want to eat milk, use artificial breastfeeding method to squeeze out the ewes of the ewes to feed the lambs; when the ewes cannot squeeze milk or the milk is of poor quality, they can squeeze the colostrum of other ewes that have just been delivered. Artificial breastfeeding should be timed quantitatively, the milk should not be too cold, and the temperature should be properly heated when the weather is cold.

Fourth, immunization.

According to the actual situation of the sheep farm, the ewes are injected with the anaerobic fungus vaccine of the anaerobic fungus to prevent the disease every fall. In the high-incidence areas of this disease or the high-yielding sheep farm, the pregnant ewes are prenatal. The injection is repeated once every 14 to 21 days, so that the immunized ewe's milk contains antibodies, and the priming lambs who eat the milk containing the antibody during breastfeeding can prevent the disease.

Fifth, the use of drug prevention.

Antibiotics such as penicillin, enrofloxacin, and sulfonamides can be used for prevention within 12 hours after birth. The method of use should be in accordance with the doctor's instructions or refer to the instructions for use of the drug.

The above is a method to prevent diarrhea in lambs. It should be noted that for grazing sheep, the ewes should be kept in the sheepfold before grazing to avoid lambing during grazing.

If we confirm that the lamb is suffering from a lamb dysentery, we must promptly treat it. What drugs can I use at this time?

Antibacterial drugs such as penicillin, enrofloxacin, sulfonamides, etc. can be used, and oral pepsin can be used to help digestion;

If there is a pneumonia in a sick lamb, a combination of penicillin and streptomycin may be used for intramuscular injection. The above drugs should be used according to the drug instructions or as directed by the doctor.

At the same time of taking the above drugs, appropriate symptomatic treatment methods, such as cardiotonic, fluid replacement, sedation, and poor appetite can be administered to artificial gastric juice. The artificial gastric juice configuration method is: 10 g of pepsin, 5 ml of concentrated hydrochloric acid. Add 1 liter of water and mix 10 ml each time, 1~2 times a day for 2~3 days.
