The defensive function of the newborn calf is low, coupled with the changeable climate in autumn, and it is humid and wet. At this time, if the secretion of colostrum is delayed or insufficient, the quality is poor, and the sanitary conditions are poor, it can easily lead to diarrhea or indigestion of the newborn calves. The author used maternal blood therapy to treat yak diarrhea and received good results, farmers may wish to try. Principle: The cow’s blood contains more comprehensive nutrients and antibodies. If the newborn calf can be fed with maternal blood in a timely manner, it can stimulate the reticuloendothelial system of the calf's body and increase the number of reticuloendothelial cells in the blood. Increased phagocytosis, but also quickly raise the concentration of antibodies in the blood of yak, so that the immune effect is enhanced, and improve resistance to disease. Specific methods: Within 2 hours after the calf is born, 300-500 ml of blood from the mother’s jugular vein is collected, 2.5% sodium citrate is added, and the yak is injected intravenously once, and the calf is given enough colostrum in time. The calves that lost their maternal blood were significantly reduced in onset time. After onset of routine treatment, the course of disease was shortened by 8.5 days, the relapse rate was reduced by 43.7%, and the mortality rate was reduced by 25%. That is, the calves that lost their maternal blood had late onset of diarrhea, early recovery, and significantly reduced relapse rate and mortality. Give routine treatment for later diarrhea symptoms. As an initial laxative, clean up the gastrointestinal tract. After that, artificial gastric juice is taken orally: pepsin 10 g, dilute hydrochloric acid 5 ml, and warm water 100 ml. Mixed dissolved, 30-50 ml per dose, 3 times a day. To prevent intestinal infections, choose antibiotics or sulfonamides, 2-3 grams of oxytetracycline, 2-5 grams of sulfonamides for the first time, 1-3 grams of maintenance dose, and 0.1-0.3 grams of furazolidone. 2-3 times daily. In order to accelerate recovery, rehydration therapy can be given. With 5% glucose sodium chloride solution 500-1000 ml, once intravenously. Balance solution can also be used: 8.5 grams of sodium chloride, 0.2-0.3 grams of potassium chloride, 0.2-0.3 grams of calcium chloride, 0.2 grams of magnesium chloride, 1 gram of sodium bicarbonate, 10-20 grams of glucose powder, 0.2 grams of Annaga powder , Penicillin 300000-50 000 international units, 1000 ml of distilled water, an intravenous maintenance volume of 500 ml.
