In the article, the author presented the effectiveness of the use of the probiotic preparation Plantarum in feeding goats of the dairy direction of productivity. The scientific and economic experiment was carried out in the conditions of LLC K (F) X "EcoFarm" Zudilovo Pervomaisky district of the Altai Territory on crossbred goats of the Saanen breed. For the experiment, four groups of female goats were formed, 20 heads each. Animals of the 1st (control) group received the main economic diet,

In the diet of goats of the experimental groups in the second half of pregnancy, an experimental probiotic preparation Plantarum was additionally introduced (developed by the FSBSI «Federal Altai Scientific Center for Agrobiotechnologies» department of Siberian Research Institute of Cheese Making (SibNIIS)) at doses of 0.4 ml/kg of body weight per day for the 2nd group, 0.6 - for the 3rd group and 0.8 for the 4th. The author found that feeding of the probiotic preparation Plantarum had a positive effect on the physiological state of the experimental animals. Thus, in goats of the experimental groups, compared with the control group, a higher content of hemoglobin was noted - by 0.9 - 5.5% (p≤0.05) and erythrocytes - by 3.8-15.2% (p≤0.05 ). When analyzing the biochemical parameters of the blood of goats of the experimental groups, there was a tendency to increase the total calcium and inorganic phosphate content. Along with this, during the experiment, a positive effect of the probiotic preparation "Plantarum" on the milk productivity of experimental animals was established, which was expressed in an increase, relative to control, in gross and average daily milk yield by 0.02 - 3.27%. The use of the probiotic did not have a significant effect on the fertility of goats, but it affected the safety of their offspring, increasing it by 3.0–6.3%. The expediency of using the probiotic preparation Plantarum in the diets of goats at doses of 0.6 and 0.8 ml/kg of body weight per day is justified by cost-effectiveness calculations.
