Abstract
This article examines the impact of extruded grain feed (corn, barley) supplemented with cottonseed meal and soybean meal on milk productivity in cows of different genotypes. On most farms in Kyrgyzstan, excessive amounts of compound feed, particularly untreated corn, barley, and wheat, are required to compensate for the deficiencies in many nutrients and, naturally, to some extent, improve cow productivity. As a result, the structure of the feed ration is disrupted, and the animals' bodies are unable to fully process the nutrients in grain feed due to the "strong" structure of the grain feed. To this end, we conducted research to develop new compound feed recipes using extruded grain and to study their impact on milk productivity. The obtained research results showed that the use of extru
