The article presents the results of a scientific and industrial experiment in which the effects of different protein contents in compound feeds on the productivity indicators of lactating doe rabbits under the conditions of industrial mini-farms were investigated. The purpose of the study was to determine the optimal level of crude protein in complete granulated compound feeds in dry feeding to increase the meat productivity of rabbits. The experiment was conducted with 60 lactating White Giant doe rabbits divided into four groups of 15 animals each, one of which was a control group and the others – experimental groups. The groups differed in that the doe rabbits in the control group received compound feed with a protein content of 18 and 21% in the first 20 days and from 21 to 35 days of lactation, respectively, in accordance with the current GOST – 32897-2014 (not less than 17.7 and 21%). The lactating doe rabbits in the first experimental group received compound feed with a reduced crude protein content of 16.5% and 18% at the end of lactation. In the second and third experimental groups, the doe rabbits received compound feed with a higher protein content of 19 % and 20 % respectively in the first half of lactation, and 22 % and 23 % respectively in the second half of lactation. Based on the obtained research results on the dynamics of live weight of lactating doe rabbits, baby rabbits, feed consumption, milk productivity, and survival rate of young animals, it can be concluded that for feeding lactating doe rabbits in the conditions of industrial rabbit breeding, a complete granulated compound feed with a crude protein content of 18 % in the first 20 days of lactation and 21 % from 21 to 35 days of lactation is more effective.
