US farmers put cows on waterbeds to to boost milk production

DES MOINES, Iowa - WHEN it comes to comfort, the cows of US farmer Kirk Christie have it all - a new barn, a flat-screen television and waterbeds.

That's because of the dairy farmer's philosophy that a happy cow is a productive cow. More milk means more money, so Mr Christie doesn't mind providing the frills.

'Them cows are my girls,' said Mr Christie, who runs a farm near Slater, about 40km north of Des Moines. 'You ask anybody, I probably think more highly of those cows than I do myself.'

Waterbeds for cows

His 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 he 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.' His 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. Dr Leo Timms, a dairy scientist at Iowa State University, estimates cows with comfortable bedding produce 6 per cent more milk daily.

'There's no question, probably one of the most important things is the comfort of the surface they lay on,' said Dr Timms, who conducts research at a university dairy facility. 'The overwhelming majority (of dairy farmers) understand that.'

Mr Christie estimates his cows' milk production has increased 10 per cent 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 The Oprah Winfrey Show, Dr Phil and other shows.

'The nice part about it is they get used to different voices,' Mr 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.'- AP
