Abstract

Today, 87 percent of the number of cattle, as well as 90 percent of the number of sheep and goats in Uzbekistan are cared for by farmers. 85-90 percent of the number of livestock in our Republic belongs to peasant farms, and the preparation of feed for the livestock kept in these peasant farms should be implemented using best practices and modern technologies in developed countries, increasing the competitiveness and economic efficiency of the livestock sector is important. Based on the aforementioned information, a small-sized granulation line and a feed mixing device were created that are comparable to large-sized devices in terms of work quality and meet small livestock and poultry farms in terms of size, productivity, and energy consumption. The homogeneity of the feed mixing ratio in relation to the device’s paddle shaft rotation count and mixing duration was investigated through experimentation. The results of the trials showed that when the feed mixer paddle rotor was turning at a speed of 50 revolutions per minute and the mixing period was set for five minutes, the optimal mixing quality of ground wheat grain, ground maize grain, ground rice, and wheat bran for the manufacturing of granular feed was reached.
