Abstract
The invention relates to a feed for improving the environmental adaptability of megalobrama amblycephala. The feed comprises fructo-oligosaccharide and a bacillus licheniformis preparation. The fructo-oligosaccharide can selectively promote the growth and metabolism of beneficial bacteria in intestines, promotes the digestion and absorption of megalobrama amblycephala on nutrients, and strengthens the immunity. Bacillus licheniformis can provide substrates for metabolism of fructo-oligosaccharide, and fructo-oligosaccharide can provide nutrients for the growth of bacillus licheniformis. The fructo-oligosaccharide and bacillus licheniformis can be co-used to effectively reduce the contents of blood sugar, cortisol, and lactic acid in megalobrama amblycephala, improve the environmental adaptability of megalobrama amblycephala, promote the growth of megalobrama amblycephala, and strengthen the immunity of megalobrama amblycephala. The provided feed increases the living rate of young megalobrama amblycephala, reduces the food coefficient, has an improved protein utilization rate, promotes the growth of megalobrama amblycephala, strengthens the environmental adaptability of megalobrama amblycephala during the breeding process, shortens the raising period, and thus increases the culture benefits.
Description
Technical field
The present invention relates to technical field of aquaculture, being specifically related to a kind of feed for improving megalobrama amblycephala adaptive capacity to environment.
Background technology
Megalobrama amblycephala is the treasure in freshwater aquiculture; in recent years; Jiangsu, Shanghai, Zhejiang, Henan, Hebei etc. are the cultivation having megalobrama amblycephala in all parts of the country almost; megalobrama amblycephala has reached 700,000 tons in the annual production of China; in national cultured freshwater fish, occupy the 6th, be one of main economic fish of China, become the best selling variety on China fish market; along with improving constantly of intensive and large-scale cultivation degree, cultured output also increases year by year.But; under scale and intensive culture pattern, the adaptive capacity to environment in megalobrama amblycephala juvenile fish stage is poor; easily mortality phenomenon is there is because of the change of the condition (as temperature) that can not conform in cultivation and transportation; serious economic loss is caused to plant; hinder megalobrama amblycephala aquaculture in the fast development of China, pollution to a certain degree and destruction be also result in water environment simultaneously.Improve healthy fish, improving adaptive capacity to environment is the important channel ensureing culture fishery sustainable development, and therefore new type functional feed that is how nontoxic by some, harmless, noresidue improves its adaptive capacity to environment and seems significant.
Summary of the invention
The object of the present invention is to provide a kind of feed for improving megalobrama amblycephala adaptive capacity to environment.
For solving listing technical problem, the technical solution adopted in the present invention is: a kind of feed for improving megalobrama amblycephala adaptive capacity to environment, containing FOS and bacillus licheniformis preparation in described feed, the weight ratio of FOS and bacillus licheniformis preparation is (0.1-0.3): (1-5).
Further improvement, described feed is made up of fuel and bacillus licheniformis preparation, and wherein the percentage by weight of each component of fuel is respectively: fish meal 5%-8%, dregs of beans 22%-30%, dish dregs of rice 10%-15%, cotton dregs 10%-15%, fermentation cotton dregs 3%-5%, rice protein 3%-5%, wheat bran 5%-10%, secondary powder 18%-23%, alphalise starch 1%-2%, soybean oil 1.5%-2.5%, fish oil 1%-2%, calcium dihydrogen phosphate 1%, intensive culture fish compound premix 1%, FOS 0.1%-0.3%; The content that in described bacillus licheniformis preparation, Bacillus licheniformis falls is 1 × 10
