The invention relates to novel heterocyclic trichloromethyl derivatives, particularly 2-trichloromethyl-substituted quinazoline, benzo[d]-[1,3]-oxazine and benzo[e]-[1,3]-oxazine derivatives, for example 1,2-dihydro-2-trichloromethylquinazolin-4-one. The compounds of the invention are at least as effective as prior art trichloromethyl derivatives, which reduce the production of methane during the rumen metabolism of ruminant animals, and increase the formation of propionate at the expense of acetate, and hence improve the animals' rate of growth and their efficiency of food utilization.
该发明涉及新颖的杂环三氯甲基衍生物,特别是2-三氯甲基取代的喹唑啉、苯并[d]-[1,3]-噁嗪和苯并[e]-[1,3]-噁嗪衍生物,例如1,2-二氢-2-三氯甲基喹唑啉-4-酮。该发明的化合物至少与先前的三氯甲基衍生物一样有效,能够减少反刍动物在瘤胃代谢过程中产生的甲烷,增加丙酸盐的形成而减少乙酸盐,从而提高动物的生长速度和食物利用效率。
