Embrittlement grass carp mixed feed
Technical field
The present invention relates to a kind of aquatic animal feed, particularly embrittlement grass carp mixed feed.
Background technology
Grass carp (Ctenopharyngodon idellus), also claim " grass carp ", belonging to Cypriniformes, Cyprinidae, draft a document feeding fish, and feed source is extensive, and rapidly, output is high, is the important aquaculture kind of China in growth.Under the intensive culture condition (pond or cage culture), the Feeding in Grass Carp artifical compound feed, growth is rapid, but compares with wild individuality, and its meat is loose, the local flavor variation.Under this background, seek to improve the meat quality of cultivation grass carp, significant.
Feed average weight 1.0-1.5 kilogram grass carp March with broad bean, can make its meat occur significantly to change, grass carp muscle toughens up, crisp and flexible, and resistant to cook is not rotten, and anti-chewing claims the embrittlement grass carp, and this cultural technique is applied in some areas, south.In traditional embrittlement grass carp cultural method, the broad bean of usining is originated as the Major Foods of grass carp.With the grass carp of the mixed feed of ingesting, compare, the feed coefficient of embrittlement grass carp cultivation is higher, and the speed of growth is slower, usually needs 3-4 kilogram broad bean just can raise 1 kilogram of embrittlement grass carp (feed coefficient is 3~4); Before broad bean is thrown something and fed, need be dipped to feels like jelly can throw something and feed, and operates loaded down with trivial detailsly, and workload is large; And embrittlement grass carp culturing time long (more than April), can cause damage to fish body physiological function.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of embrittlement grass carp mixed feed in traditional embrittlement grass carp cultivation, using the existing deficiency of broad bean, to replace the broad bean used in traditional embrittlement grass carp cultivation, reach the purpose of grass carp meat embrittlement, also keep fish body normal growth, alleviate the raising workload, improve culture-pool water quality.
Technical problem to be solved by this invention can be achieved through the following technical solutions:
A kind of embrittlement grass carp mixed feed is prepared from by the raw material of following weight percent meter:
Dregs of beans: 5~50%, Cottonseed Meal: 5~50%, rapeseed dregs: 0~50%; Broad bean: 5~50%, broad bean skin: 5~50%, fish oil or soya-bean oil: 0.5~2%, Choline Chloride: 0.3~0.6%, calcium dihydrogen phosphate: 1~2%, multidimensional, the premix of many ore deposits: 1~1.5%, methionine: 0.1%~0.5%.
In a preferred embodiment of the invention, this embrittlement grass carp mixed feed is prepared from by the raw material of following weight percent meter:
Dregs of beans 25%, Cottonseed Meal 25%, rapeseed dregs 15%; Broad bean 20%, broad bean skin 10%, fish oil 1%, calcium dihydrogen phosphate 2%, multidimensional, many ore deposits premix 1.4%, Choline Chloride 0.5%, methionine 0.1%.
Embrittlement grass carp mixed feed of the present invention adopts dregs of beans in conventional fish feed formula, cotton dregs, the dish dregs of rice etc., and obsolete broad bean, obsolete broad bean skin in conventional fish feed formula; Multidimensional, the premix of many ore deposits directly adopt commercially available fish feed additive, using calcium dihydrogen phosphate as the phosphorus source; Fat adopts soya-bean oil, fish oil etc.; Amino acid is the spacetabs type methionine.
The embrittlement grass carp that outstanding feature of the present invention is to use this feed to raise, the embrittlement grass carp that its speed of growth is raised than broad bean is improved 50% left and right, and the 3-4 of feed coefficient when feeding broad bean reduces to 2.0~2.5, and growth performance approaches the grass carp that conventional feed is fed; And the present invention directly throws something and feeds, needn't, as prior immersion broad bean, greatly alleviate the raising workload; Simultaneously, throw the reduction of the amount of raising and the raising of efficiency of feed utilization, reduced the livestock waste discharge, improved pond water quality, improved the quality of embrittlement grass carp.
The specific embodiment
Following specific embodiment is only detailed description of the invention, does not form the restriction to technical solution of the present invention.
Embodiment 1:
A kind of embrittlement grass carp mixed feed is prepared from by the raw material of following weight percent meter:
Dregs of beans 25%, Cottonseed Meal 25%, rapeseed dregs 15%; Broad bean 20%, broad bean skin 10%, fish oil 1%, calcium dihydrogen phosphate 2%, multidimensional, many ore deposits premix 1.4%, Choline Chloride 0.5%, methionine 0.1%.
After 3 cultivation, the grass carp rate of body weight gain of the broad bean of throwing something and feeding, embrittlement grass carp mixed feed, conventional mixed feed is respectively: 70%, 110%, 125%, and feed coefficient is respectively 3.5,2.3,2.0; Collagen of muscle content is respectively 0.43%, 0.39%, 0.30%; Muscle hardness (Hardness) is respectively 9120,8910,7035; Muscle adhesivity (Gumminess) is respectively 2510,2310,1550.The ingest grass carp of embrittlement grass carp mixed feed, the embrittlement grass carp that its speed of growth is raised than broad bean is improved more than 50%, and feed coefficient significantly reduces, and growth performance approaches the grass carp that conventional feed is fed, and meat quality approaches the embrittlement grass carp of the broad bean of ingesting.
Embodiment 2:
A kind of embrittlement grass carp mixed feed is prepared from by the raw material of following weight percent meter:
Dregs of beans 25%, Cottonseed Meal 5%, rapeseed dregs 20%; Broad bean 17.5%, broad bean skin 7.5%, fish oil 1%, calcium dihydrogen phosphate 2%, multidimensional, many ore deposits premix 1.4%, Choline Chloride 0.5%, methionine 0.1%.
After 3 cultivation, the grass carp rate of body weight gain of the broad bean of throwing something and feeding, embrittlement grass carp mixed feed, conventional mixed feed is respectively: 70%, 115%, 125%, and feed coefficient is respectively 3.5,2.2,2.0; ; Collagen of muscle content is respectively 0.43%, 0.37%, 0.30%; Muscle hardness is respectively 9120,8410,7035; Muscle adhesivity (Gumminess) is respectively 2510,2100,1550.The ingest grass carp of embrittlement grass carp mixed feed, the embrittlement grass carp that its speed of growth is raised than broad bean is improved more than 50%, and feed coefficient significantly reduces, and growth performance approaches the grass carp that conventional feed is fed, and meat quality approaches the embrittlement grass carp of the broad bean of ingesting.
Embodiment 3:
A kind of embrittlement grass carp mixed feed is prepared from by the raw material of following weight percent meter:
Dregs of beans 25%, Cottonseed Meal 20%, rapeseed dregs 15%; Broad bean 22.5%, broad bean skin 12.5%, fish oil 1%, calcium dihydrogen phosphate 2%, multidimensional, many ore deposits premix 1.4%, Choline Chloride 0.5%, methionine 0.1%.
After 3 cultivation, the grass carp rate of body weight gain of the broad bean of throwing something and feeding, embrittlement grass carp mixed feed, conventional mixed feed is respectively: 70%, 100%, 125%, and feed coefficient is respectively 3.5,2.5,2.0; Collagen of muscle content is respectively 0.43%, 0.40%, 0.30%; Muscle hardness (Hardness) is respectively 9120,8970,7035; Muscle adhesivity (Gumminess) is respectively 2510,2400,1550.The ingest grass carp of embrittlement grass carp mixed feed, the embrittlement grass carp that its speed of growth is raised than broad bean improves 43%, and feed coefficient significantly reduces, and growth performance approaches the grass carp that conventional feed is fed, and meat quality approaches the embrittlement grass carp of the broad bean of ingesting.
