The feeding and management of fattening beef cattle should be dewormed regularly.

Fattening cattle should be dewormed in vivo and in vitro before fattening. Parasites in vivo and in vitro can reduce feed intake, inhibit weight gain and increase in fattening period. Parasites absorb nutrients from intestinal surimi and affect the growth and development of fattening cattle. The dosage is calculated according to the body weight of the cow, and the insect is dewormed head by head. The methods of deworming include mixing, filling, hypodermic injection and so on. Deworming drugs can choose albendazole, avermectin, anti-peristaltic sensitivity and so on. Deworming was performed again one week later.
