First, the time for deworming beef cattle
Autumn and winter is an important time for beef cattle to repel insects. It is beneficial to the pest control of beef cattle in winter, autumn and winter and the smooth wintering. Deworming before maturity means using large doses of drugs to drive out all the adults and larvae in beef cattle at the end of winter. Thereby reducing the insect load of beef cattle. Avoid beef cattle death in spring.
2. Precautions for deworming beef cattle:
1, select insecticide. The principle of drug selection for beef cattle deworming is high efficiency, low toxicity, economy and convenient use. When large-scale deworming is carried out, it is necessary to carry out deworming tests. The dosage, usage, effect and toxic and side effects of drugs for expelling intestinal worms should be known before they are applied on a large scale.
2. Grasp the appropriate time for deworming. To deworm beef cattle, we should not only prescribe the right medicine, but also pay attention to the time of administration. If the drug is used too early, the insect repellent effect will not be achieved, and if it is too late, it will affect the development of beef cattle and form a stiff cow. The time of deworming depends on the species, development and season of the insect. In general, it is best to deworm beef cattle for the first time at the weight of beef cattle 120 kg, killing more with one arrow.
3. Fasting before deworming. In order to facilitate the absorption of anthelmintics, we should fast 12~ 18 hours before anthelmintics. Mix the medicine and feed evenly at 7~8 pm, and let the beef cattle eat it all at once. If beef cattle don't eat it, a small amount of salt water or saccharin can be added to the feed to enhance palatability.
4. The livestock house site should be disinfected to prevent insects and eggs from being infected after being eaten by beef cattle. The requirement is that the feces and pathogenic substances discharged by beef cattle after deworming should be treated harmlessly. Feces are cheap and sterilized by biological fermentation. The floor, wall and feeding trough of beef cattle house should be disinfected with 5% lime water.
5. beef cattle should be carefully observed after deworming. If poisoning occurs, such as vomiting, diarrhea and other symptoms, let him drink half-cooked mung bean soup immediately. For patients with diarrhea, 50 grams of charcoal or pot bottom ash are mixed with feed and fed for 2-3 days. Beef cattle can only be slaughtered and eaten after 2 1 day.
6. Beef cattle that have just entered the house are prone to stress reactions due to environmental changes, transportation, shock and other reasons. We can add astragalus antibody to drinking water for 65,438+0 weeks and feed more grass or green hay. After 2 days, add a small amount of bran and gradually transition. It is necessary to observe the intake, excretion and mental state of cattle, and wait until the whole cow is stable before expelling worms and nourishing the stomach.
