The article presents the results of the physiological experience conducted on the campus for the maintenance of service dogs of the Department of Cynologists of the Perm Institute of FPS of Russia in 2015. The aim of the study is to identify feed from the proposed ready-made dry food Stout and Pedigree, to replace the prepared feed from natural products, most satisfying the needs of service dogs while saving money for the organization Feeding. The objectives of the study are to study the variability of nutrients by dogs of ready-made dry food “Stout”, “Pedigree” against the background of prepared food from natural products; to establish the impact of the studied feed on the live mass of animals; calculate the cost of daily rations. For what of the three groups of scientific and economic experience was selected by 3 males, by the method of pairs of analogues, to participate in the balance experience. High digestibility of nutrients prepared by dogs of the control group has been established. Dogs of the first experimental group, who received Stout's feed, absorbed a dry substance worse than the control substance by 0.23 %, but better than the II experienced at the stern “Pedigree” by 3.92 % (P < 001). The organic invariability rate in the first experimental group was 3.56 % higher than the II experimental group. Invariability ratios: raw protein in the first experimental group was 3.64 % higher than the II of the experimental group, fat by 5.70% (P < 0.001), raw fiber by 5.29 % (P < 001), and nitrogen-free extractive substances by 2.85% (P < 0.01). Taking into account the weighting of animals it is established that the dogs of the control group on the prepared feed, received a positive dynamics in the live mass. In animals, on the dry stern “Stout”, the indicators of live mass were stable. In dogs, on the stern “Pedigree” there was a decrease in live mass. Stout dry feed is recommended for replacement prepared in summer, and in winter – with an increase in daily norm by 10 %.
