This article examines the relationship between the shape, size and size of the udder and udder of Bushuev cows on different categories of farms and their milk yield. It was determined that the milk yield of cows belonging to the form of bowl-shaped udder in all farms was higher from 720.9 kg to 641.8 kg than their peers belonging to the form of round udder. In comparison, the udder of cows with a cup-shaped udder was 3.3 cm to 2.2 cm wider, the udder length was 9.1 cm to 7.8 cm longer, and the udder circumference was 6.3 to 8.7 cm bigger, the udder depth was 1.6 cm to 2.7 cm longer, and the nipple diameter was higher 0.06 cm to 0.35 cm, than the udder of cow belonging to a round udder. It was found that the daily milk yield in bowl-shaped udder cows was 29.3% to 25.4% higher than in their round udder-like counterparts.
