Federal law allows the Agriculture Department to buy meat and poultry products to help farmers and ranchers affected by natural disasters.

The announcement came as Obama criticized Republican vice presidential candidate Paul Ryan for blocking a farm bill that could help farmers cope with the drought. Obama touted his efforts to help farmers as he began a three-day tour of the battleground state he won in 2008.

“That will help ranchers who are going through tough times right now,” Obama said.

Obama said the government would boost its purchases of meat now, while prices are low, and freeze much of it for later use.

The USDA plans to buy up to $100 million of additional pork products, $50 million of chicken, $10 million of lamb and $10 million of catfish. The Defense Department, a large purchaser of beef, pork and lamb, was expected to look for ways to encourage its vendors to speed up purchases of meat.

“The purchases will help mitigate further downward prices, stabilize market conditions and provide high quality, nutritious food to recipients of USDA nutrition programs,” Agriculture Secretary Tom Vilsack said in a statement.

The USDA has spent about $37 million on pork products so far this year. If it spends an additional $100 million, that would be more than twice what the agency spent on pork in 2011.

Obama has pledged a wide-ranging response to the drought. His administration is giving farmers and ranchers access to low-interest emergency loans, opening more federal land for grazing and distributing $30 million to get water to livestock.
