Metabolizable energy level in compound feeds for pigs
Abstract
Nitrogen-free extractive substances of cereals contain up to 72 % of grains energy reserves of these crops, including about 4 % of sugar and 68 % of starch. Carbohydrates of oilseeds (rape) account for about 8 % of energy reserves, peas - 64 %, soybeans - 13 %. After extracting the fat fraction from vegetable protein feeds, part of energy extracted from the carbohydrate portion increases up to 47.9 % in soybean meal, up to 46.3 % in rapeseed cake and up to 61.3 % in rapeseed meal. Thus, the metabolizable energy level in ingredients of cereals depends to a large extent on availability of nitrogen-free extractive substances, mainly sugar and starch. It is proposed to use the new calculation algorithm to determine the metabolizable energy level in feeds for pigs, which was not previously used in our republic, which includes quantitative indicators of raw nutrients level (protein, fat, fiber, starch and sugar), digestibility ratios of these substances and the constants of numerical values.
