Beef, pork, poultry and even eggs, cheese and milk are expected to get more expensive as livestock owners go out of business or are forced to slaughter more animals to cope with rocketing costs for corn-based animal feed.

New York ? Raging Midwest floodwaters that swallowed crops and sent corn and soybean prices soaring are about to give consumers more grief at the grocery store.

In the latest bout of food inflation, beef, pork, poultry and even eggs, cheese and milk are expected to get more expensive as livestock owners go out of business or are forced to slaughter more cattle, hogs, turkeys and chickens to cope with rocketing costs for corn-based animal feed.

The floods engulfed an estimated 2 million or more acres of corn and soybean fields in Iowa, Indiana, Illinois and other key growing states, sending world grain prices skyward on fears of a substantially smaller corn crop. The government will give a partial idea of how many corn acres were lost before the end of the month, but experts say the trickle-down effect could be more dramatic later this year, affecting everything from Thanksgiving turkeys to Christmas hams.

Rod Brenneman, president and chief executive of Seaboard Foods, a pork supplier in Merriam, Kan., that produces 4 million hogs a year, said high corn costs were already forcing producers in his industry to cut back on the number of animals they raise.

“There’s definitely liquidation of livestock happening,” and that will cause meat prices to rise later this year and into 2009, said Brenneman, who is also the vice chairman of the American Meat Institute.

Brenneman’s cost for feeding a single hog has shot up $30 in the past year because of record-high prices for corn and soybeans, the main ingredients in animal feed. Passing that increase on to consumers would tack an extra 15 cents per pound onto a pork chop.

Feed costs

It’s a similar story for U.S. beef producers, who now spend a whopping 60 percent-70 percent of their production costs on animal feed and are seeing that number rise daily as corn prices hover near an unprecedented $8 a bushel, up from about $4 a year ago.

“This is not sustainable. The cattle industry is going to have to get smaller,” said James Herring, president and CEO of Amarillo, Tex.-based Friona Industries, which buys 20 million bushels of corn each year to feed 550,000 cattle.

Corn’s prices were already rising before the floods, driven up 80 percent over the past year as developing countries like China and India scramble for grains to feed people and livestock. U.S. production of ethanol, an alternative fuel that can be made with corn, has also pushed prices higher, prompting livestock owners to lobby Washington to roll back ethanol mandates.

Before the floods, corn farmers were enjoying record profits selling the grain to feed animals and for use in cereals and as a sweetener in soda and candy. But a sharply smaller corn crop could wipe out those gains.

In Iowa, the No. 1 U.S. corn grower, floods inundated about 9 percent of corn crops, representing about 1.2 million acres – almost 1.5 percent of the country’s anticipated harvest.

In Indiana, another 9 percent of corn and soybean crops were flooded, potentially costing farmers up to $840 million in lost earnings, Indiana Agriculture Director Andy Miller said.

Other flood damage

Floodwaters also tossed farm equipment, sprayed cornfields with debris and silt and sucked away large chunks of topsoil. For livestock owners and meat producers, the damage may be felt long after the corn grows back.

Even before the floods, Tyson Foods was complaining that high grain prices would drive up its costs by $600 million this year. The world’s largest poultry company has already raised its prices over the past year, and expects to keep raising them, CEO Dick Bond told analysts at a conference in May.

Higher feed prices will eventually filter through to the cost of milk, cheese and yogurt, too, since 65 percent to 75 percent of a dairy farmers’ production costs are for feed, said Chris Galen, a spokesman for the National Milk Producers Federation.

With the cost of animal feed only going higher, many poultry and dairy farmers are starting to look for cheaper alternatives.

Nebraska dairy farmer Dan Rice, who has 1,500 cows, said one alternative is to buy some of the byproducts of cereal or flour production, but they’re not nearly as productive compared to corn.

“If we all feed less corn and get less production, then the price at the grocery stores are going to go up,” said Rice, who supplies milk to grocery stores in Omaha and around Kansas City.

Without easy ways to cut costs, many livestock producers will have little choice but to slaughter more animals and send them to market.

“The cost of Thanksgiving and Christmas turkeys will go up this year, and maybe even more next year,” said Hill, who is also the chairman of the National Turkey Federation.
