At present, the price of local bulls is generally about one catty from 35 yuan to 45 yuan, and the weight of local bulls is about 1000 catty. Its local bull should weigh about 500 Jin after slaughter, so a cow can be sold for 17500 yuan.

If farmers sell their own cattle, the profit is 16300 yuan; if they sell them to dealers, the profit of a catty of beef is between 19 yuan, so farmers also have 9500 yuan.
