Calf diarrhea is a calf disease caused by intestinal peristalsis, incomplete absorption or difficulty in absorption, which leads to intestinal contents and a large amount of water being excreted. Its clinical features are loose stool, soft stool or watery stool, vomiting, dehydration, weight loss and acidosis, and its death is faster. The causes of calf diarrhea can be divided into two types: nutritional diarrhea (caused by excessive feeding of milk, sudden change of milk composition, inferior milk substitute and low milk temperature). ) and infectious diarrhea (caused by bacteria, viruses, parasites, etc. To treat this disease, it is best to find out the cause first and then give medicine. 1. Treat diarrhea caused by bacteria with sulfanilamide, and take it orally at a weight of 0. 1 g per kilogram of calves, three times a day for three days. Second, florfenicol, according to the calf weight per kilogram of 0.0 1 ~ 0.02g intramuscular injection, three times a day, continuous injection for three days. In case of virus infection, Radix Isatidis injection, 20ml/ head, can be used. Third, when the calf has an appetite or can suck on its own, it can be given oral rehydration salts (sodium chloride 3.5g, 65438+ potassium chloride 0.5g, sodium bicarbonate 2.5g, glucose 20g, 1000ml normal water) for the calf to drink freely. When it is not self-inhalable, 6% low molecular dextran, physiological saline, 5% glucose and 5% sodium bicarbonate 250 ml, hydrocortisone 100 mg and vitamin CCCC10 ml can be mixed and injected intravenously into calves. Light rehydration once a day, heavy rehydration twice a day. Critical calves can also be treated with whole blood transfusion. Generally speaking, the bovine blood of sick calves can be mixed with 50 ml of 2.5% sodium citrate and 450 ml of whole blood for intravenous injection. Four, oral 5 ~10g bismuth nitrate or 50 ~100g clay or10 ~ 20g activated carbon, or enema to discharge intestinal toxic substances. You can also use 5 ~ 10 tablets of lactobacillus and feed 5 ~ 10 tablets to the mother. After mixing, take it orally once, twice a day for 2 ~ 3 days, and the curative effect is good. 5. It can also be treated with traditional Chinese medicine: Radix Pulsatillae 20g, Radix Isatidis 20g, Coptidis Rhizoma 15g, Cortex Fraxini 15g, Sanguisorba officinalis 15g, Mume Fructus 15g, Poria cocos 10g, and decocted in water every day. At the same time, we should also pay attention to keep the cowshed clean and dry, remove feces and dirt in time, and often disinfect it to pave the way for drying mattress grass. Strengthen the feeding management of pregnant dairy cows, give enough protein, minerals and vitamins to ensure that dairy cows have a good nutritional level, so that they can secrete enough milk after delivery to meet the physiological needs of newborn calves. Cow breasts should be kept clean. If conditions permit, cows can be vaccinated with Escherichia coli vaccine before delivery 1 month; Calves should eat colostrum as soon as possible after birth. At present, cattle raising is being vigorously promoted throughout the country, especially in poor areas. Its market benefit stability factors and other reasons have attracted everyone to be very optimistic about the market prospects and the development of aquaculture scale. In fact, cattle can be raised all year round, which has advantages and disadvantages. But as long as we pay attention to the ventilation, safety and hygiene of the cowshed, cows will not get sick in general, and their physique is much stronger than that of people. At present, the homes of ordinary manufacturers have undergone formal quarantine and epidemic prevention. Therefore, as long as it is raised according to conventional breeding methods, it is a good season all year round. Now let me tell you the reason for raising cattle. At present, soybeans, corn and other crops are growing just right, and this year is expected to be a bumper harvest! Soybean and corn are cattle's favorite concentrated feed. So now I buy back about 300 Jin of calves and feed them with the broken wheat straw. When soybeans and corn are harvested, it is the key moment for calves to speed up fattening. At this time, green corn stalks, corn, soybeans and so on. Everything is sufficient, and the price is also the bottom of the year. This time is a good opportunity to feed cattle or store materials, which greatly reduces the cost of raising cattle (as we all know, corn and soybeans in the country are more expensive). Therefore, scientific farming cannot be ignored. Seize the opportunity, according to the growth of cattle and the coordination of various factors, cattle can not but raise hair! ! !
