"The cows are my girls," said Christie, who runs a farm near Slater, about 25 miles (40 kilometers) north of Des Moines. "You ask anybody, I probably think more highly of those cows than I do myself."
Christie's 23 cows spend about 18 hours a day on waterbeds he installed in November. He said the beds, durable rubber mats that lay flat on the ground and are filled with water, were popular with the animals from the beginning. They provide heat for the cows in the winter and coolness in the summer, depending on the water Christie pipes in.
The beds are covered with woods chips for extra padding to prevent friction. "They really took to them right away," he said. "When they're laying down chewing cud, they're comfortable and happy."
Christie's cows aren't the only ones enjoying such comforts. Industry experts say waterbeds are increasingly being used in dairy farms across the country, as well as in Canada and Europe, where the idea originated more than a decade ago.
The idea is to boost milk production by making the cows more comfortable. Leo Timms, a dairy scientist at Iowa State University, estimates cows with comfortable bedding produce 6 percent more milk daily.
Christie estimates his cows' milk production has increased 10 percent since he installed the waterbeds.He figured a flat-screen TV couldn't hurt, either, so the cows are spending the spring snoozing in their beds and enjoying (1) "The Oprah Winfrey Show", "Dr. Phil"and other shows.
"The nice part about it is they get used to different voices," Christie said, "A lot of people like to come in and look at my barn. When somebody different comes in and talks, the cows don't get all nervous because they're used to hearing different voices."
While Christie swears by waterbeds, most dairy farmers in the United States use other bedding methods for cows, such as mattresses or sand,industry experts said. ■AP
