The causes of the disposal of the animals and the main milk productivity indices of cows having different genotypes depending on the method of housing and technology of milking

The causes of the disposal of the animals and the main milk productivity indices of cows having different genotypes depending on the method of housing and technology of milking have been analyzed. For all the evaluated periods the animals which were milked with a robotic system in the free stall barn surpassed the cows which were kept on a leash and milked into the pipeline with the help of milking machines. Along with this, in the cows kept in the free stall barn the limb diseases caused culling more often than in other groups of animals under study.

Milk yield and properties of the udder Black-and-White and Simmental breeds under usage of a robotic milking system

We analyzed the milk production and the basic properties of udderfresh cows Black-and-White and Simmental breeds using a robotic system of milking. According to different periods of lactation and the basic properties of the udder the cows of Black-and-White breed of dairy productivity trends lead. Therefore, to use a robotic milking system the black-motley breed are more suitable in comparison with the combined productivity of Simmental directions under the purposeful selection.
