Abstract
The invention discloses a mixed feed for mixed culture of litopenaeus vannamei and grass carp and a preparation method of the mixed feed. The mixed culture is prepared from multiple kinds of feeds such as fish meal, meat and bone meal, bean pulp and the like, which are preferred and easy to digest and absorb, through the steps of grinding, quality crafting, granulating and drying. Coated methionine is added in the formula of the feed to improve the balance of whole formula in an amino acid mode; squid liver paste is added to improve the food attracting performance of the feed; shrimp shell meal, monocalcium phosphate, cholesterol and the like are added into the feed to ensure the requirements for calcium, phosphorus and the like during shell change of the litopenaeus vannamei and skeletal development of the grass carp; and bacillus subtilis and beta-glucan are added to enhance the digestive tract function and the immune capacity of bred animals. The raw materials in the mixed feed are all conventional raw materials, and have stable sources and low prices, therefore, the feed cost is effectively reduced; and furthermore, the mixed feed has high effective conversion rate and low feed coefficient (0.9-1.4), the survival rate of the litopenaeus vannamei during breeding is improved by about 30%, the survival rate of the grass carp is improved by about 20%, and the total output of the two bred animals is improved by about 30%.
Description
Technical field
The present invention relates to a kind of aquatic animal feed, particularly relate to a kind of Environment of Litopenaeus vannamei Low and grass carp compound feed used for polyculture.
Background technology
Environment of Litopenaeus vannamei Low (Litopenaeus vannamei), originates in America.According to statistics, Environment of Litopenaeus vannamei Low output accounts for more than 75% of China's prawn total output in recent years.Along with the develop rapidly of its aquaculture, relevant research is also in like a raging fire carrying out.The scientific achievements nearly hundred such as the open Chinese patent application about it, as Chinese patent application CN101099541A low salinity stocking Environment of Litopenaeus vannamei Low additive premix, Chinese patent application CN1923032A humic acid Litopenaeus vannamei compound feed etc.
Grass carp (Ctenopharyngodon idellus) has been commonly called as: grass carp, careless grass carp.It belongs to Cypriniformes Cyprinidae Leuciscinae grass carp and belongs to, and is typical herbivorous fishes.Because its growth is rapid, feed resource is wide, is one of four large Chinese carps of CHINESE FRESHWATER cultivation.
Along with the development of culture fishery, intensive culture pattern encounters the bottleneck phase of himself development gradually.Now, advantage place that Polyculture has intensive culture pattern not have due to it (as the sick diseases prevention of control of raising together with between kind, mutual reciprocity and mutual benefit etc.) and growing up gradually, and receive everybody great attention.Wherein Environment of Litopenaeus vannamei Low and grass carp are desalinated pond polyculture pattern and have become one of important aquaculture model in Pearl River Delta, Guangdong and even neighboring area.While its cultivation development, the research being directed to this Polyculture is but comparatively weak.The trophism researchs such as its special feed are then less.Generally everybody throws something and feeds with Litopenaeus vannamei compound feed or Ctenopharyngodon idellua feed.Feed effective rate of utilization is low, cannot meet Environment of Litopenaeus vannamei Low and grass carp well completely to comprehensive demand of nutrition, and operation is too loaded down with trivial details.
