Assistance for Missouri's dairy farmers appears to be one of the first bills the Legislature will send to Gov. Jay Nixon.
The House gave initial approval to the dairy farm bill Wednesday and the Senate is expected to pass its version Thursday.
Supporters say the bill is needed to keep Missouri's milk providers in business.
The measure provides a subsidy to help dairy farmers pay for insurance, a scholarship for students studying dairy farming and funds for research on the industry.
Opponents say the state government should not interfere with the free market or try to fix an industry regulated at the federal level.
Funds for the program would have to be approved separately and would come from existing sales tax on dairy products.
