The efficiency of using grain waste in feeding dairy cattle

Currently, one of the main tasks in Russia is to create effective grain crops, in which natural and agrotechnical factors are used maximally to increase productive value of plants. In the current situation, it is being successfully and actively solved in agriculture. At the same time, the yield of grain crops shows a constant increase, which would be impossible without financial investments and logistical support, as well as achievements of science and technology in the industry. Part of the grain crops is lost during storage and processing. In this regard, there is a need to study the possibility and effectiveness of using grain waste in feeding dairy cattle in order to prevent losses. The results of the experiment on the organoleptic evaluation of grain waste showed benign characteristics. A study of the chemical composition of feed showed that the nutritional value of feed flour is slightly lower (in protein - by 5.8-13.4%, in EKE - by 8.4-14.6%), however, it can still be attributed to concentrated feeds. Thus, it can serve as a balancing food in feeding diets. During the experiment on lactating cows, it was determined that the use of the mill offals and feed flour in the diet of lactating cows during the lactation recession is effective from the point of view of economic indicators. This is confirmed by the productivity of dairy cattle during the study period - in animals using grain waste, it was not much lower than when using feed grain.
