preparation example Construction

[0016] The preparation method of the feed for preventing and treating fish hemorrhagic disease of the present invention is as follows: mixing animal feed, plant feed, oil, vitamins, and minerals to obtain feed for preventing fish hemorrhagic disease.

[0017] Furthermore, the plant feed is fermented and mixed with animal feed, oil, vitamins, and minerals to obtain fish hemorrhage disease prevention feed.

[0018] In the present invention, the animal feed includes animal offal meal, lard residue, chicken meal, meat and bone meal, and fish meal. Preferably, the animal feed is composed of animal offal meal, lard residue, chicken meal, meat and bone meal, and fish meal; fats include phospholipids, Terrestrial animal oil, fish oil, and soybean oil, preferably the fat is composed of phospholipids, terrestrial animal oil, fish oil, and soybean oil. The terrestrial animal oil includes lard and tallow.

Embodiment 1

[0021] The feed for the prevention and treatment of fish hemorrhage disease is mixed with animal feed, plant feed, oil, vitamins and minerals to obtain the feed for the prevention and treatment of fish hemorrhage disease. The specific formula is shown in Table 1 (the value is by mass). Feed three uses fermented plant feed, and feed one, feed four, feed five, and feed six use unfermented plant feed.

[0022]

[0023] The activated fermenting bacteria are added to the mixture of plant feed powder and sterile water, and the fermentation is kept to obtain fermented plant feed, which is then mixed with other components of the feed to prepare pellet feed; wherein the inoculum of the strain is plant feed 3.5% of the quality. Specifically, in feed two, the plant feed was fermented with Bacillus subtilis (conventional strain) at 37°C for 3 days; in feed three, the plant feed was fermented at 30°C with Aspergillus niger (conventional strain) for 3 days.

Embodiment 2

[0030] Example 2 Pond grass carp experiment

[0031] On May 5, 2018, two-year-old grass carp in a 20-mu pond suffered from hemorrhagic disease, and there were dead fish but not serious (12 grass carp a day); Feed 3 started on May 6 (Example 1, the feeding method is conventional Method), for 10 consecutive days, the condition was effectively controlled on May 8 (no more fish died), 10 days later (May 15), sample fish without bleeding symptoms (curing rate 100%), and then resume regular feed Feeding; after that, once there is a sign of bleeding disease, the above-mentioned feeding method is adopted immediately, and there is no bleeding disease until the market is on the market, and the fish is in good physical condition.

Abstract

The invention discloses a fish bleeding disease prevention and treatment feed, as well as a preparation method and application thereof. An animal feed, a plant feed, a grease, vitamins and mineral substances are mixed to obtain the fish bleeding disease prevention and treatment feed. Optimally, the plant feed is treated by adopting zymogeneous bacteria, so that a prevention and control effect on the bleeding disease is improved. The practice shows that by adopting the fish bleeding disease prevention and treatment feed provided by the invention, fish grow well, no bleeding disease infection occurs or controlling and solving can be carried out timely after the bleeding disease occurs, and meanwhile, the fish bleeding disease prevention and treatment feed provided by the invention does not adopt medicine compositions so as to be free from drug residues, and is low in cost; and in general, the economic loss brought to farmers due to the bleeding disease can be effectively avoided.

Description

Technical field [0001] The invention belongs to fish breeding technology, and specifically relates to a feed for preventing and treating fish hemorrhagic disease, and a preparation method and application thereof. The hemorrhagic disease prevention and control program developed by the present invention has achieved good results in production practice. Background technique [0002] Fish hemorrhagic disease has been prevalent since the mid-1980s and has spread in various freshwater aquaculture fields in my country. This disease can harm a variety of fishes. Almost all common freshwater fish have the disease, and the incidence is usually 60% to 100%. Whether it is pond farming, mountain pond farming or reservoir farming, disease will occur, which can reduce production by more than 20%-50% and cause huge economic losses. [0003] Fish hemorrhage disease can be divided into three types according to the different bleeding sites: one is the red muscle type. The diseased fish has no obviou...
