The invention discloses a toughened ctenopharyngodon idellus compound feedstuff which is prepared by using soybean meal, cottonseed meal, rapeseed meal, broad bean, broad bean peel, fish oil or soybean oil, choline chloride, calcium dihydrogen phosphate, a multi-vitamin and multi-mineral premix, and methionine. An outstanding characteristic of the invention is that with the feedstuff, the growth speed of the toughened ctenopharyngodon idellus is improved by approximately 50% than that of toughened ctenopharyngodon idellus fed with broad beans, a feed coefficient is reduced from 3-4 of a broad bean feeding method to 2.0-2.5, and growth performance of the toughened ctenopharyngodon idellus is close to that of ctenopharyngodon idellus fed with common feedstuffs. The feedstuff provided by the invention can be directly used for feeding, and pre-impregnation as required by broad beans is not needed, such that feeding work load is greatly reduced. Also, with the invention, the feedstuff dosage is reduced, feedstuff utilization rate is improved, culture waste discharge is reduced, pond water quality is improved, and toughened ctenopharyngodon idellus quality is improved.
