When comparing the above manual methods of pusher feed mixtures, it was established that when using a shovel for 100 cows at a time, 5.01 minutes of working time were spent, when using forks – 8.12 minutes, and when using a hand scraper – only 2.12 minutes. In modern complexes, the fastest way to hill feed is with a tractor. This takes 1.02 minutes per 100 cows. The “Butler Gold” robot works much more slowly. It takes 4.96 minutes for this operation. It was found that the feeding behavior of dairy cows depended on feeding management factors, including the frequency of feed distribution and its pusher. The activation of the feeding behavior of animals was characterized by an increase in the number of animals near the feed table when performing the technological operations of feed distribution and pushing (moving feed to the animal on the feeding table). Performing the technological operation of distributing feed mixtures twice a day led to an increase in the number of cows near the feed table by 20.9 % – 22.0 % of the total number of animals in the pen (126±5.2 heads). Performing the technological operation of pusher feed also led to an increase in the number of cows near the feed table by 2.3 % – 11.3 % of the total number of animals in the group. The remains of feed removed beyond the border of the feed table were perceived by the animals as fresh bedding for rest, which led to a reduction in the total feeding front.
