The research was carried out in “Udmurtia” agricultural produc-tion co-operative (collective farm) of the Vavozhsky district of the Udmurt Republic". A complex for keeping 1200 cows with loose cubicle technolo-gy for cow keeping with milking in the milking parlor using the rotary milking equipment was built on the farm for the first time in the Udmurt Republic. In the course of the study, technological operations during keep-ing, feeding, milking cows at the rotary milking unit were studied; the tim-ing of the cow milking process and the sequence of operations were carried out.

The article presents materials on the results of the study of the effect of the Tamir biopreparation on the growth indicators of repair heifers, the subsequent dairy productivity of cows and animal health as a result of the use of the biopreparation Tamir with a loose technology of keeping cattle on a deep litter. The work analyzed the technology of maintenance of repair heifers and cows, studied the indicators of live weight and average daily increments of repair heifers in different growing periods, studied the composition and method of preparation of the biopreparation "Tamir", the technology of biopreparation application for processing organic manure, analyzed the indicators of disposal of repair young animals and cows dairy productivity of first-calf cows for 100 days of lactation and by age categories for two years before and three years after the use of the biopreparation, studied the results of laboratory tests for compost suitability for application to the soil. The research revealed an increase in milk productivity, average daily gains of repair heifers, live weight at the first insemination, decrease in the number of retired repair heifers and cows from the main herd due to limb diseases. According to the results of the research, expert recommendations were given to the farm.
