Small dairy cow learns to go to the toilet to urinate It's easy to pee, but hard to hold back. Some animals, like wolves, choose to mark territory by controlling their bladders to urinate, while cows roaming the pasture urinate freely. Jan Langbein, an animal psychologist at the Research Institute for Farm Animal Biology in Germany, said: "The impression is that some animals have no way to control urination, but since dogs can be trained, horses can be trained, why? Can't train cows?"
In a study published last September (2021) in Current Biology, Longben and colleagues toilet-trained 16 calves for 45 minutes every other day. In the beginning, they kept the calves in special toilets called MooLoos, where food was served through holes in the wall when the calves urinated. After the calf learns that there is a reward for peeing in the toilet, he can go outside. wedding photo retouching services If the calves automatically returned to the toilet to urinate, they were rewarded again, but if they urinated outside, they were subjected to a water spray for three seconds. After 10 days of training, 11 of the calves had a 77% chance of using the toilet when urinating, showing that cows can indeed quickly learn to go to the toilet to urinate.
The team's goal now is to automate the system and use it on farms with less monitoring. Yang Peiliang, an assistant professor at the Department of Power and Mechanical Engineering at Tsinghua University in Taiwan, who was not involved in the research, commented that concentrating cow urine in toilets can help reduce pollution and greenhouse gases, as well as reduce the spread of human and animal diseases. "If animal waste is treated in the same way as human waste, these diseases can be eliminated," she said. wombat poop is square
