Nothing but the best for these bovines, this farm outside Moscow recently installed high-definition flat-screen TVs in the barn. No, not for the farmer, but they are for his cows. He's hoping crystal-clear pictures of alpine meadows and green grass will help boost milk production.
"There have been experiments when cows listen to music, but this is never being done with video images. We show the cows pictures of green juicy alpine grass."
The farm installed 6 plasma screens for a-month-long experiment, with 10 cow watching a film, and another 10 not. Since the experiment began, the cows watching TV have been producing on average 3 litters more milk everyday than cows that are not watching TV.
Veterinarian said it's just a matter of relaxing the cows, so they are in the right mood for the milking.
"This is a positive impact on the cows. They give more milk. This means they are in a good mood. Everything is good with them. There is no negative influence on their health. There shouldn't be any side-effects."
Now, with only additional 3 litters per day, it might be hard for the farmers to milk the profit out of the experiment, but they are still optimistic.
"We've only been conducting this experiment for a month, so we haven't paid off the investment yet. But if we did it for a year or more, we would recover all the investment."
