    • The use is provided of a composition as a feed additive which comprises one or more endoglucanases, and 0-20 % by weight, based upon the content of cellulase proteins in the composition, of a cellobiohydrolase. The endoglycanases may be one or more of EGI, EGII, EGIII and any functionally active derivative of any thereof. Such endoglucanases may be obtained from a genetically modified strain of the fungus Trichoderma. Also provided is an enzyme-based feed additive which comprises EGI and/or EGII which lack the cellulose binding domain, and 0-20 % by weight, based upon the content of cellulase proteins in the additive, of a cellobiohydrolase. A further enzyme-based feed additive is provided which comprises a cereal-based carrier, one or more endoglucanases, and 0-20 % by weight, based upon the content of cellulase proteins in the additive, of a cellobiohydrolase. Such enzyme-based feed additives can be incorporated into a cereal-based feed which includes one or more of barley, wheat, triticale, rye and maize. The feed additive has the advantage of improving the feed conversion ratio and/or increasing the digestibility of a cereal-based feed in which it is included.
    • 提供的组合物作为饲料添加剂,其包含一种或多种内切葡聚糖酶,并且基于组合物中纤维素酶蛋白质的含量为0-20重量%的纤维二糖水解酶。 所述凝集素可以是EGI,EGII,EGIII及其任何的任何功能活性衍生物中的一种或多种。 这样的内切葡聚糖酶可以从真菌木霉的遗传修饰菌株获得。 还提供了一种基于酶的饲料添加剂,其包含缺乏纤维素结合结构域的EGI和/或EGII,并且基于添加剂中纤维素酶蛋白质的含量为0-20重量%的纤维二糖水解酶。 提供了另外一种基于酶的饲料添加剂,其包含基于谷物的载体,一种或多种内切葡聚糖酶,和基于添加剂中的纤维素酶蛋白质含量为0-20重量%的纤维二糖水解酶。 这种基于酶的饲料添加剂可以掺入包括大麦,小麦,黑小麦,黑麦和玉米中的一种或多种的谷类饲料中。 饲料添加剂具有提高饲料转化率和/或增加其中包含谷物饲料的消化率的优点。
