Low-cost plecoglossus altivelis compound feed and preparation method thereof

Abstract

The invention relates to a fish feed, and especially relates to a low-cost plecoglossus altivelis compound feed. The invention also relates to a preparation method of the compound feed. The compound feed is composed of the following components in parts by weight: 10 to 20 parts of soybean meal, 10 to 20 parts of peanut meal, 10 to 20 parts of cotton meal, 8 to 16 parts of strong flour, 8 to 14 parts of rice bran, 6 to 10 parts of caloglossa leprieurii, 5 to 8 parts of dry clam worm powder, 5 to 8 parts of ulva powder, 4 to 8 parts of mung bean powder, 4 to 6 parts of pea powder, 4 to 6 parts of dry carrot powder, 4 to 6 parts of potato powder, 3 to 5 parts of cordate houttuynia, 3 to 5 parts of purslane, 2 to 4 parts of rhizoma kaempferiae, 1 to 3 parts of vallisneria natans, 1 to 3 parts of saxifrage, 2 to 4 parts of shell powder, 3 to 5 parts of fish oil, and 2 to 4 parts of xanthan gum. The cost of the compound feed is low, the raw materials are green and environment-friendly, the compound is attractive to plecoglossus altivelis, and the living rate is high.

Description

technical field [0001] The invention relates to a fish feed, in particular to a low-cost sweetfish compound feed; the invention also relates to a preparation method of the above-mentioned low-cost sweetfish compound feed. Background technique [0002] The most urgent problem brought about by the rapid growth of population is to provide food for human beings. As a kind of high-value food with high protein and low fat in food, people's demand for it is naturally increasing day by day.

However, the proportion of amino acids required by fishmeal is the closest to that of aquatic animals. The aquaculture animals in the compound feed after adding fishmeal prefer to eat, and the addition of fishmeal can ensure the rapid and healthy growth of aquaculture animals. Use other protein sources instead of fishmeal to prepare sweetfish When formulating feed, the feed quality is often difficult to guarantee, aquatic animals usually do not like to eat, and in severe cases, it will affect the normal growth and development of sweetfish
