Abstract

The invention discloses a tenebrio moliter feed and a preparation method and belongs to the technical field of feed processing. The tenebrio moliter feed is characterized by being composed of following components, by weight, 60-85% of miscanthus floridulus, 14-38% of a substrate and 1-2% of a microbial strain. In the tenebrio moliter feed, the miscanthus floridulus, which is abundant in source and is low in cost, is employed as a main raw material for preparing the tenebrio moliter feed for replacing conventional wheat bran and rice bran so that a breeding cost can be effectively reduced. Meanwhile, the raw material is free of territory limit and can be planted in all parts of the country, thereby greatly promoting development of a breeding industry of tenebrio moliter. The preparation method is easy to carry out. The feed, prepared through fermentation, is greatly reduced in the content of crude fibers, is increased in the content of crude proteins, is increased in nutrients, is enhanced in palatability and is ensured to have an intake rate being not less than 97%.

Description
