Сапропели белорусского Полесья - важный источник кормов для животных

Abstract

Researches on efficiency of sapropel form “Chervonoe” Lake use in feeding of young cattle were conducted in four groups of young animals. As a result of the experiment it was determined that inclusion of 4 %, 6 % and 8 % of dehydrated sapropel into animal feeds instead of cereals increases transformation of metabolizable energy of diet into live weight gains by 3.4-12.5 %, and as a results the ratio of productive use of metabolizable energy of the feed increases from 0.27 to 0.29-0.33. An amount of sapropel in compound feed at steers fattening may be to 6 -8 %. Such compound feeds are consumed by animals with pleasure, stimulate metabolic processes in the body, and as a result the average daily weight gains increase by 2-3.5 % at feed cost decrease by 8 %. Feeding young cattle grown for meat with dehydrated sapropel instead of cereals in amount of up to 2.9 % in dry matter of diet allows not only to save the forage grain, but also to increase the efficiency of feed metabolizable energy used for live weight gain.
