IMPROVING DEVICES FOR MASSAGING THE UDDER OF HEIFERS BASED ON THEIR CLASSIFICATION CHARACTERISTICS

Abstract

The paper presents a classification of technical means used in the preparation of animals for lactation, and based on it, a design and technological scheme of a device for massaging the udder of heifers with a combined principle of action on the breast tissue of the animal is proposed. It is concluded that the rational design of the massage device should provide a combined pneumatic-mechanical massage of the udder of heifers by intensive compression and stretching of the animal’s breast tissue in the stroke of the massage. In this case, a short-term intake of a portion of air into the massage bell during the unloading stroke should completely restore the blood circulation in the udder of the animal that was disrupted in the previous stroke.
