Because cattle and sheep eat coarse feed, pasture and other foods that are easy to contact with bacteria, the digestive tract is easily infected with various parasitic diseases, affecting the growth effect of beef cattle and sheep. Therefore, in order to ensure the realization of the effect of fattening cattle and sheep, it is best to deworm them before fattening, and the following six problems should be paid attention to to do a good job of deworming.
First, choose the right anthelmintic drugs
The effect of deworming drugs on insect repellent is the most critical, and the use of efficient, low-toxicity, economical and easy-to-use insect repellent drugs can achieve the ideal insect repellent effect. At present, there are many types of parasitic diseases, deworming drugs are also uneven, farmers do not use good drugs for disease species is also the main reason for the failure of deworming; generally avermectin or ivermectin is a common drug for deworming, which is effective for a variety of parasitic diseases, but is not suitable for trematodes, tapeworms, etc. Therefore, deworming should be based on different types of different drug instructions to achieve results.
Second, purposeful and targeted
When deworming cattle and sheep, it is necessary to clarify the types of parasites to be expelled: the common parasites of general cattle are roundworms, liver flukes, tapeworms, cattle lice, cattle ticks, cattle scabies mites, etc.; the common internal and external parasites in sheep are mainly intestinal tubercles, hookworms, whipworms, lung filaria, scabies, sheep nose flies, sheep lice, ticks, etc.; the types of parasites should be judged according to clinical symptoms, so as to achieve effectiveness and thoroughness.
Third, regular deworming
Due to seasonal and regional differences, it is better to deworm once a year in spring and autumn. Prophylactic dosing can be done once a quarter, and therapeutic deworming can be performed in individual cases that are seriously affected by parasites.
Fourth, fast before deworming
To facilitate the absorption of deworming drugs, fasting should be taken for 12 to 18 hours before deworming. Social beef cattle and meat sheep need to calculate the dosage of drugs first, and then crush the deworming drugs, evenly hold them into the feed, mix the drugs with the feed at 7 to 8 pm, and let them eat at once.
Fifth, disinfection of the rear yard after deworming
Generally, after feeding insect repellent drugs, the feces excluded by the animals should be cleaned and fermented centrally, and the pens, floors, walls and feeding troughs should be disinfected with lime water to ensure the effect of disinfection after deworming.
Sixth, after deworming, observe more
If some meat sheep and beef cattle are poisoned after feeding insect repellent drugs, such as vomiting, diarrhea and other symptoms, they should be immediately allowed to drink semi-cooked mung bean soup. For those who are thinner, take 50 grams of charcoal or pot bottom ash, mix it into the feed and feed it, and take it for 2 to 3 days to see the effect.
