Problems solved by technology

However, the current aquatic feed additive products have the problem of poor effect and single curative effect: some aquatic feed additive products only add probiotics or vitamins, and these products only work to improve water quality or provide nutrients. Breeding must purchase a large number of various single products for compounding
Therefore, aiming at several major problems that urgently need to be solved in aquaculture, such as slow body weight growth, poor anti-stress ability of aquatic animals, low immunity and low feed utilization rate, targeted development of compound microecological preparations can effectively It is an efficient and comprehensive aquatic feed additive product urgently needed by the aquaculture industry to solve various problems in aquaculture.

Embodiment 1

[0027] Embodiment 1: the influence on the growth rate of body weight of aquatic animals

[0028] Compound microecological preparation: the number of viable bacteria of Bacillus subtilis 5.0×10 9 cfu / g, Saccharomyces cerevisiae 5.0×10 7 cfu / g, the citric acid content accounts for 10% of the total weight, the vitamin C accounts for 5% of the total weight, and the mannan oligosaccharide accounts for 1% of the total weight. The above ingredients are evenly mixed to obtain a compound microecological preparation.

[0029] The prepared compound microecological preparations were added to the basal diets of sea cucumber, Penaeus vannamei and turbot at a mass ratio of 1:100, and the breeding experiments of sea cucumber, Penaeus vannamei and turbot were carried out.

[0030] Sea cucumbers, Penaeus vannamei and turbot were randomly divided into groups, with 40 sea cucumbers (10g ± 0.5g) in each group, 20 vannamei shrimp in each group (5g ± 0.2g), and 20 turbots in each group (390g ± 11g...

Embodiment 2

[0037] Embodiment 2: the impact on the anti-stress ability of aquatic animals

[0038] Compound microecological preparation: the number of viable bacteria of Bacillus subtilis 5.0×10 9 cfu / g, viable count of Bacillus licheniformis 5.0×10 9 cfu / g, Saccharomyces cerevisiae 5.0×10 7 cfu / g, citric acid content accounts for 30% of the total weight, vitamin C accounts for 30% of the total weight, and oligomeric chitosan accounts for 10% of the total weight. The above ingredients are evenly mixed to obtain a compound microecological preparation.

[0039] The prepared compound microecological preparations were added to the basal diets of sea cucumber, Penaeus vannamei and turbot at a mass ratio of 1:100, and the breeding experiments of sea cucumber, Penaeus vannamei and turbot were carried out.

[0040] Sea cucumbers, Penaeus vannamei and turbot were randomly divided into groups, with 40 sea cucumbers (10g ± 0.5g) in each group, 20 vannamei shrimp in each group (5g ± 0.2g), and 20 ...

Embodiment 3

[0047] Embodiment 3: The impact on the mortality of aquatic animals

[0048] Compound microecological preparation: the number of viable bacteria of Bacillus subtilis 5.0×10 9 cfu / g, viable count of Bacillus licheniformis 5.0×10 9 cfu / g, malic acid content accounts for 15% of the total weight, vitamin E accounts for 10% of the total weight, and mannan oligosaccharide accounts for 5% of the total weight. The above ingredients are evenly mixed to obtain a compound microecological preparation.

[0049] The prepared compound microecological preparation was added to the basal diets of sea cucumber, Penaeus vannamei and turbot at a mass ratio of 1:200, and the breeding experiments of sea cucumber, Penaeus vannamei and turbot were carried out respectively.

[0050] Sea cucumbers, Penaeus vannamei and turbot were randomly divided into groups, with 40 sea cucumbers (10g ± 0.5g) in each group, 20 vannamei shrimp in each group (5g ± 0.2g), and 20 turbots in each group (390g ± 11g ). E...

Abstract

The invention relates to the field of feed additives and discloses a composite micro-ecological preparation and application thereof. The composite micro-ecological preparation disclosed by the invention comprises probiotics, organic acids, vitamins and oligosaccharides, wherein the total viable count of the probiotics is more than or equal to 1*10<9> cfu / g; the organic acids account for 10-30% of the total weight; the oligosaccharides account for 1-10% of the total weight; and the vitamins account for 5-30% of the total weight. Tests indicate that the composite micro-ecological preparation disclosed by the invention has the effects of improving the growth rate of body mass, improving the anti-stress capability, improving the feed utilization rate and reducing aquaculture death rate. The composite micro-ecological preparation disclosed by the invention can be prepared into veterinary drugs, feed additives or nutritious supplementary to be singly used, also can be mixed in aquatic animal feed to be directly fed, is wide in application range and has excellent economic and social effects.

Description

technical field [0001] The invention relates to the field of feed additives, in particular to a compound microecological preparation and its application. Background technique [0002] Because of its nutritional and medicinal value, aquatic products are gradually and deeply recognized by people, which makes its market and consumer groups gradually expand, and the demand is increasing year by year. With the increasing demand in the aquatic products market, efficient and comprehensive aquatic feed additives have become catalysts for the high production of modern aquaculture. However, the current aquatic feed additive products have the problem of poor effect and single curative effect: some aquatic feed additive products only add probiotics or vitamins, and these products only work to improve water quality or provide nutrients. Farming must purchase a large number of various single products for compounding. Due to the different product performance and product quality of differ...
