TOTAL EVALUATION OF EXTERIOR PECULIARITIES OF COWARD MORNING N THEIR PRODUCTIVITY

Automated milking system-one of the latest developments, combining thelatest technology of machine milking, veterinary requirements and a specialapproach to the process. The use of automated systems allows not only toincrease the daily milk yield, but also to preserve the health and long-termproductivity of cows. The aim of the research was a comprehensive study of themain morphological features of the udder exterior characterizing thesuitability of cows for robotic milking. The morphological assessment of theudder exterior was carried out in cows (n=138 heads) used in the roboticmilking unit of Delaval company, in one of the breeding farms of the Kalugaregion. According to the results of the studies, it was found that when milkingcows on a robotic installation, animals with a low attachment of the anteriorlobes than the posterior ones, with additional nipples, close nipples, thinless than 5 mm, with a goat udder shape are not suitable. Not all animals aresuitable for robotic technology, from 3 to 10 % of cows are culled whenforming a herd. Uneven development of individual quarters of the udder,undesirable structure of the nipples, small sphincter extensibility can have animpact on reducing the rate of cow milking. The greater the difference betweenthe development of individual shares of the udder, the higher the proportion ofunproductive time spent at milking, the more it is spent on milking 1 kg ofmilk. These defects and shortcomings of the exterior of the udder cows in theherd of black-and-white breed adversely affect the process of connecting thesleeves to the nipples of the udder, as a result of the connection time in somecases reaches 2 or more minutes.


Keywords:
