Use of PVMC based on local plant raw materials in the ration of young sheep

Under the conditions of intensive sheep breeding technology, special attention is paid to the production of compound feed and complete feed mixtures. In recent years, in the production of compound feed for lambs, various feed additives have become widespread, most of which are imported, which leads to an increase in the cost of compound feed. The purpose of the work was to develop a recipe for a new feed additive based on local feed resources, study the effect of replacing part of the granulated compound feed with the developed protein-vitamin-mineral concentrate (PVMC) in different proportions depending on the age of lambs to obtain high-quality mutton from them and increase their meat productivity, as well as the efficiency of rearing for the reproduction of crossbred young ewes. A scientific justification for the development of PVMC under the conditions of the Central Black Earth Region of Russia for including it in the ration of early weaned crossbred lambs (Tsigai×Edilbaevskaya) has been provided in the work. The efficiency of feed use is assessed. The effect of PVMC on meat productivity in young rams and wool productivity in young ewes has been established. The optimal option for replacing part of the compound feed with PVMC has been established, which allowed improving the quality of meat and meat productivity. In order to increase the precocity, livability and productivity of young sheep in farms breeding crossbred sheep under the conditions of the Central Black Earth Zone of the Central Region of the Russian Federation of various types of ownership, it is recommended to include the developed PVMC when rearing early weaned lambs for the age of 2–4 months in the amount of 30 %, 4–6 months – 25 % and 6–8 months – 20 % of the mass of the fed compound feed.
