Description

A kind of compound feed for snakeheads and preparation method thereof
Technical field
The present invention relates to a kind of fish meal and preparation method thereof, especially a kind of compound feed for snakeheads and preparation method thereof.
Background technique
Snakehead is commonly called as snakeheaded fish, snakeheaded fish etc., belongs to Ophiocephaliformes, murrel suborder, murrel section, is the common ferociousness predacious fish in China One of.Snakehead meat flavour is delicious, full of nutrition, pierces between no flesh, and it is adaptable it is strong, water quality requirement is low, growth is fast, yield is high, The features such as productivity effect is good, the huge market demand.And still in its infancy about compound feed for snakeheads at present, feed nutrition at Part is unreasonable, fails in view of comprehensive nutritional need in snakehead growth course, slow growth, head is small, light-weight, meat Easily there is abnormal phenomenon, are unfavorable for the breeding scale of snakehead in difference, cultivation later period；And snakehead cultivation mainly uses fresh food, deposits Consumption resource, pollution environment, infect disease the problems such as, and disease management can bring cultured product edible safety risk, Increase aquaculture cost and environmental pollution, therefore the compound feed for snakeheads for developing a kind of high-efficiency environment friendly is extremely urgent.
Summary of the invention
The object of the present invention is to provide a kind of compound feed for snakeheads of feed request for meeting snakehead cultivation and its preparation sides Method.
The present invention is realized by following technical solution.
A kind of compound feed for snakeheads, it is made of the raw material of following proportions:
Inlet steam fish meal 20~25%, shrimp med 4~7%, powder of pork 5~10%, dehulled soybean meal 5~10%, high muscle face Powder 17~23%, a- starch 3~5%, rapeseed meal 10~15%, corn protein powder 5~7%, rice bran 10~15%, calcium dihydrogen phosphate 1~2%, soyabean lecithin oil 3~5%, vitamin premix 1%, mineral substance premix 1%, synergy adjusting compound 2~3%.
Further, the compound feed for snakeheads comprising have the component of following mass percent:
Inlet steam fish meal 20%, shrimp med 6%, powder of pork 5%, dehulled soybean meal 10%, Strong flour 18%, a- starch 2%, rapeseed meal 15%, corn protein powder 5%, rice bran 10%, calcium dihydrogen phosphate 1.5%, soyabean lecithin oil 3%, vitamin premix Material 1%, mineral substance premix 1%, synergy adjust compound 2.5%.
Further, the vitamin premix is emerging 401 vitamin premix of share of commercially available perseverance；The mineral substance premix For emerging 401 mineral substance premix of share of commercially available perseverance；
The synergy adjusts compound and is made of lutein, taurine, brewer's yeast and nucleotide, by accounting for mixed feed Weight percent meter, include lutein 0.3~0.5%, taurine 0.5~1%, brewer's yeast 1~1.5%, nucleotide 0.1~ 0.3%.
The preparation method of above-mentioned compound feed for snakeheads comprising have following steps:
S1, each component raw material is weighed according to the proportion, and dregs of beans therein, rapeseed meal are subjected to coarse crushing, sieving；
S2, the dregs of beans after being sieved in S1 step and rapeseed meal are uniformly mixed with remaining other component raw materials, will be uniformly mixed Material afterwards pulverizes and sieves again；
S3, material smashed in S2 step is modulated granulation, cured；
S4, the feed granules after curing are dried, is packaged into bag after cooling.
Further, in the S1 step, the dregs of beans in raw material, rapeseed meal is subjected to coarse crushing, it is made to cross 28 meshes.
Further, in the S2 step, material after mixing is crushed in micronizer again, makes to mix It closes material and crosses 80 meshes.
Further, in the S3 step, smashed material is passed through to 95~100 DEG C of temperature of nothing in modem Vapor modulate 5~8 minutes, then make material 95~98 DEG C at a temperature of enter extrusion granulator in pelletize；It will system The pellet obtained continues to carry out for 25~35 minutes under conditions of temperature is 95~100 DEG C and humidity is 90%~98% ripe Change.
Further, in the S4 step, the particle after curing is dried under the conditions of 70~85 DEG C, snakehead cooperation is made and raises Material.
Beneficial effects of the present invention are embodied in:
1, contain multiple protein source in feedstuff, overcome the unbalanced problem of single Proteinogenic amino acids, be conducive to Efficiency of feed utilization is improved, ammonia nitrogen discharge is reduced, reduces environmental pollution.
2, by using synergy adjusting compound, there is following effect in formula:
Lutein is added, snakehead pigementation ability is not only improved, additionally it is possible to improve erepsin activity, improve snakehead Growth performance, strengthen immunity；Taurine, which is added, as a kind of non-nutritive additive can improve the palatability of feed, pierce Swash ingesting for snakehead, promotes the growth of snakehead, enhance the immunity and premunition of body；Brewer's yeast and nucleotide have strong Strong attractant can enhance the feed intake of palatability and snakehead, improve alimentary canal Micro Ecosystem, promote beneficial bacterium proliferation, drop Low enterogastric diseases incidence.
3, feed of the present invention effectively solves the decline of snake-head immunity power and mixed feed nutrition caused by breeding environment deteriorates not The problem of balance, realizes the quick sustainable development of snakehead aquaculture industry chain, has great economic benefit and social benefit.
