Problems solved by technology

Compared with grass carp fed with compound feed, the feed coefficient of embrittled grass carp is higher and the growth rate is slower. Usually, 3-4 kg of broad beans are needed to raise 1 kg of embrittled grass carp (feed coefficient is 3-4); Before feeding, it needs to be soaked until it becomes soft before feeding. The operation is cumbersome and the workload is heavy; moreover, if the brittle carp is cultured for too long (more than 4 months), it will cause damage to the physiological functions of the fish.

Abstract

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.

Description

technical field [0001] The invention relates to a feed for aquatic animals, in particular to a compound feed for embrittled grass carp. Background technique [0002] Grass carp (Ctenopharyngodon idellus), also known as "grass carp", belongs to Cyprinidae, Cyprinidae, and belongs to herbivorous fish. It has a wide range of bait sources, rapid growth, and high output. It is an important aquaculture species in my country. Under intensive culture conditions (pond or cage culture), grass carp eats artificial compound feed and grows rapidly, but compared with wild individuals, its meat quality is loose and its flavor becomes poor. In this context, it is of great significance to seek to improve the muscle quality of cultured grass carp. [0003] Feeding grass carp with an average weight of 1.0-1.5 kg with broad beans for three months can significantly change the meat quality. Grass carp muscles become firm, brittle and tough, resistant to cooking and chewing. It is called brittle ...
