How long can cattle ruminate after eating vitamin B complex?

Half an hour.

Solution: enema with two bottles of beer and edible oil, 10 rhubarb soda tablets to drink water, and cefotaxime combined with vitamin B complex for those who don't eat it. Cattle and sheep began to ruminate half an hour after injection.

Cattle's failure to ruminate is generally called foregut retardation, mainly because long-term feeding of powdery or soft feed has a great relationship with feeding management. Secondary cattle do not ruminate, which is often secondary to rumen and abomasum diseases, postpartum ketosis, peritonitis and other diseases, which will lead to cattle not ruminating, and most diseases will lead to cattle not ruminating in the early stage.
