Problems solved by technology

After several years of breeding, it was found that rainbow trout had a high mortality rate and relatively slow growth, which greatly damaged the breeding benefits of the breeder. Although the feeder also made some improvements or updates in fish feed, feed additives or breeding methods, However, fish survival or mortality and disease resistance did not improve significantly

Embodiment 1

[0038] The preparation of fish feed additive comprises the following steps:

[0039] (1) Pre-heat the oven to 280°C, then put Tenebrio molitor in and dry until Tenebrio molitor fully expands;

[0040] (2) Take out the dried Tenebrio molitor, crush it, and pass through an 80-mesh sieve to make Tenebrio molitor body powder;

[0041] (3) In parts by weight (unit: kg), weigh 1000 Tenebrio molitor body powder, 1.5 parts edible yeast powder, 1.5 parts Epimedium, 4.5 parts insect chitin, and 1.5 parts of Taibai ginseng water extract, and place them in a mixing container. Stir and mix to obtain the fish feed additive.

[0042] Feed preparation for rainbow trout farming:

[0043] The fish feed additive and anchovies are fully mixed according to the weight ratio of 5:100 (unit: kilogram) to prepare rainbow trout breeding feed. Feed 2 times a day.

Abstract

The invention provides a fish feed additive, which comprises the following ingredients by weight: 1000 parts of mealworm body powder, 1-2 parts of edible yeast powder, 1-2 parts of epimeddium, 4-5 parts of insect chitin and 1-2 parts of rhizome of david woodbetony aqueous extract. A preparation method comprises the following steps: drying the mealworm body powder and then crushing into powder, then mixing with other ingredients according to the formula proportion to obtain the product. The fish feed additive is the green additive with ecological and environmental protection, the fish feed used for feeding the fish has the advantage of high feed utilization rate, and is capable of obviously enhancing the disease resistance ability of fish, simultaneously raising the growth speed of fish, increasing the survival rate of the rainbow trout and the culture benefit.

Description

technical field [0001] The invention relates to a biological additive and its preparation method and application, in particular to a fish feed additive and its preparation method and application, belonging to the field of fish feed processing. Background technique [0002] The research and application of feed additives started late in our country, but with the rapid rise of the feed industry and the large-scale operation of the breeding industry, it has developed rapidly, and has played a huge role in promoting the development of animal husbandry. At present, there are more than 300 varieties of feed additives, and more than 150 kinds are frequently used. There are about 20-80 kinds of additives used in each compound feed, depending on the species and age of the feed. [0003] However, with the application of feed additives, some unavoidable practical problems have also been brought, that is, the use of feed additives has also produced many negative effects. It has been fo...
