Ptitsegradskaya, Sergiev Posad-11, Moscow Province, 141300 Russia, e-mail еta164@yandex.ru, dissovet@vnitip.ru, vnitip@vnitip.ru A b str a c t crops, particularly rape ( A recent trend in the world’s crop production is an intensified cultivation of oil-yielding ), as a source of vegetable oils and valuable protein for animal nutrition. <...> Rape is especially promising crop for climatic and soil conditions of the Russian Federation as it can be grown almost all over the country. <...> Amino acid composition in rape proteins is well-balanced, and the lysine level is almost similar to that in soy, while the methionine, cystine, Ca and P levels are much higher. <...> In animal seeds, as well as rape oilcake, meal and oil are used. <...> In rape seeds the fat content is 40 %, the protein level reaches 23 % and cellulose amounts to 4 %. <...> However, their use in hen’s feeding is limited due to poor digestibility of seed shells and specific composition. <...> In rape oil the level of unsaturated fat acids is high, i.e. 60.0-70.0 % for oleic acid, 23.3 % for linoleic acid and 10.5 % for linolenic acid which can regulate biosynthesis of prostaglandins thus effecting positively the reproductive function. <...> Biological, energy and protein value of rape seed meal is high and similar to that of high-protein feed-stuff of animal origin. <...> These proteins are enriched with irreplaceable amino acids, and the lysine and Scontaining amino acids levels amount to 5.7 and 5.0 %, respectively. <...> Anti-nutritive compounds including erucic acid and glucosinolates are the factors limiting use of rapeseed and related products in animal nutrition. <...> In the article the methods for improving nutritive value of rapeseed products are discussed, including genetic selection of rape, thermal processing and supplementation of diets with enzyme preparations. <...> Classification of rape cultivars is considered with regard to fatty acids and glucosinolates content in seeds («++», «0+», «+0», «00», «000»). <...> Supplementation of broiler diets with rapeseed cake containing 0.41 % of isothiocyanates and 0.25 % of erucic acid together with a designed enzyme preparation MEC-CP-4 (Russia) is proposed as an effective feeding technology. <...> In poultry this additive allows to use fodder containing 7.5; 10.0 and 15.0 % of rapeseed <...>
