Abstract

The invention discloses a feed water-retaining agent natural composition and an application thereof in a fish feed, and belongs to the technical field of feed and additives thereof. The technical problem to be solved by the invention is that an existing water retention additive for a feed is generally a chemical compound, has corrosivity and irritation, and is poor in palatability to fishes. The water-retaining agent natural composition comprises at least two of an eucommia ulmoides bark extract, an aloe bark extract, a mulberry leaf extract and a ginkgo leaf extract. The invention further discloses composition forms and optimal concentrations of an eucommia ulmoides bark ethyl acetate extract, an aloe bark water extract and a mulberry leaf water extract. The natural composition provided by the invention is used for feed water retention, has no residue, no toxic or side effect, does not pollute the environment, can achieve combined synergism, and has more economic benefits.

Description

technical field [0001] The invention relates to the technical field of feed and its additives, in particular to the natural composition of feed water-retaining agent and its application in fish feed. Background technique [0002] At present, my country's regulations on the moisture content of ordinary compound pellet feeds are generally 11-12%. However, the dry-pressed pellet feed system commonly used by large-scale feed enterprises at present causes serious water loss in raw materials during processing. The moisture content of pellet feed is about 8%. The moisture content of feed pellets is too low, which is an economic loss for feed enterprises. Some companies have used a certain proportion of mixed organic acids to keep the moisture in the feed pellets. However, the organic acids are chemical compounds, expensive, poor palatability to fish, and there is a risk of residues in fish meat. Their safety has been questioned. [0003] my country's current laws and regulations...
