Embodiment 1

[0021] Lactic acid, 20kg; fumaric acid, 12kg; malic acid, 10kg; calcium formate, 14kg; hawthorn powder, 16kg; ebony, 14kg; schisandra, 10kg; bentonite, 4kg.

[0022] The preparation method of the composite additive in this embodiment includes the following steps: ultrafinely pulverize the accurately weighed components, and pass through a 100-mesh sieve. Then first add bentonite, hawthorn powder, black plum and schisandra into the mixer for mixing, and then add lactic acid, fumaric acid, malic acid and calcium formate in turn for mixing. After thorough mixing, when the mixing uniformity reaches a coefficient of variation ≤ 5%, the prepared composite additive is a bio-organic acid composite additive for Litopenaeus vannamei of the present invention.

Embodiment 2

[0024] Lactic acid, 18kg; fumaric acid, 18kg; malic acid, 14kg; calcium formate, 8kg; hawthorn powder, 20kg; black plum, 12kg; schisandra, 7kg; bentonite, 3kg.

[0025] Its preparation method is with specific embodiment 1.

Embodiment 3

[0027] Lactic acid, 15kg; fumaric acid, 14kg; malic acid, 16kg; calcium formate, 10kg; hawthorn powder, 17kg; ebony, 16kg; schisandra, 12kg.

[0028] Its preparation method is with specific embodiment 1.

Abstract

The invention discloses a biological organic acid composite additive for Litopenaeus vannamei and a preparation method thereof. The composite additive is prepared from the following raw materials in parts by weight: 15-20 parts of lactic acid C3H6O3, 12-18 parts of fumaric acid C4H4O4, 10-16 parts of malic acid C4H6O5, 8-14 parts of calcium formate C2H2O4Ca, 16-20 parts of hawthorn powder, 12-16 parts of dark plum, 7-12 parts of schisandra chinensis and 0-4 parts of bentonite. The preparation method is as follows: weighing the components at a weight ratio; crushing the components, and uniformly mixing the components in a mixer, wherein the adding sequence is as follows: the bentonite, the hawthorn powder, the dark plum and the schisandra chinensis are firstly added, and the other components are added. The acidifier adopted by the biological organic acid composite additive disclosed by the invention can be used for effectively perfecting the environmental pH value in the digestive tract of Litopenaeus vannamei for a long time, cooperatively sterilizing and inhibit bacteria, promoting ingestion and digestion functions, effectively protecting the digestive tract health of the Litopenaeus vannamei and improving the breeding survival rate of the Litopenaeus vannamei. The biological organic acid composite additive disclosed by the invention has an obvious prevention and treatment effect on bacterial digestive system diseases in the existing Litopenaeus vannamei breeding.

Description

technical field [0001] The invention relates to a feed compound additive, in particular to a bio-organic acid compound additive for Litopenaeus vannamei and a preparation method thereof. The invention belongs to the technical field of artificial cultivation of Litopenaeus vannamei. Background technique [0002] Vannamei shrimp (Litopenaeus vannamei), native to the Americas, has quickly become an upstart in the aquaculture industry due to its high meat yield, ease of intensive farming, and delicious meat. It has been nearly 15 years since Litopenaeus vannamei was introduced into our country for farming. However, during the continuous breeding process, especially in the past two years, the breeding of Litopenaeus vannamei has been plagued by diseases, and the breeding situation has gradually deteriorated. Through the investigation, research and textual research of many experts at home and abroad, the main pathogens of the failure of shrimp farming in recent years (red body, ...
