Three experiments with five wether each were carried out in order to investigate the influence of various levels of flavomycin (0, 5 and 10 mg per animal and day) on apparent digestibility of artificially dried grass. A short time individual feeding experiment (42 days) with 9 bulls and a long term individual feeding experiment (225 days) with 52 heifers were conducted. Animals consumed 0 or 30 mg flavomycin per day. Parameters of rumen fermentation were investigated. Feed intake and weight gain were measured in the experiment with heifers. Flavomycin did not significantly influence the apparent digestibility of organic matter and crude nutrients as well as parameters of rumen fermentation. Flavomycin did not influence dry matter intake, but increased significantly weight gain (49 g per animal and day, 10.5%) and reduced feed and energy required per kg weight gain (10.6%) in heifers. The reasons of ergotropic effects of flavomycin are mostly unknown at present.
进行了三项实验，每项实验有5只阉羊，以研究不同水平的黄霉素（每只动物每天0、5和10毫克）对人工干燥草表观消化率的影响。对9头公牛进行了短期个体饲养实验（42天），对52头小母牛进行了长期个体饲养实验（225天）。动物每天摄入0或30毫克黄霉素。研究了瘤胃发酵参数。在小母牛实验中测量了采食量和体重增加。黄霉素对有机物和粗养分的表观消化率以及瘤胃发酵参数没有显著影响。黄霉素不影响干物质采食量，但显著增加了小母牛的体重增加（每只动物每天49克，10.5%），并降低了每千克体重增加所需的饲料和能量（10.6%）。目前，黄霉素促肾上腺能效应的原因大多未知。
