On such farms, though, it is easy for diseases to spread from one animal to another. This can lead to many cows dying on one farm. As a result, cows are often kept separately from a young age. Scientists in Canada researched the effects of keeping young cows in this way. They compared such cows with ones that had been kept with another cow. The researchers showed a red plastic container, which the cows had never seen before, several times to each cow. The cows that had been kept in pairs were interested in the container_at first but soon ignored it. ( 25 )。 the cows that had been kept alone continued to react as if it was the first time they had seen the Container. The researchers concluded that cows kept alone are more sensitive to new things. This is important news for farmers. If cows cannot get used to the feeding and milking machines, milk production slows down. The researchers believe farmers would have fewer problems with feeding and milking if cows were kept in very small groups, rather than separately. The researchers also say that diseases are not sucha big problem for small groups. There should be little risk of ( 26 ) if only two or three of them are kept together.
