Tilapia mossambica iron-rich blended hard particles feed and its preparation method

Abstract

The invention discloses a Tilapia mossambica iron-rich blended hard particles feed, which comprises the following ingredients by weight: 10-14 parts of iron-rich fermented raw materials, 8-10 parts of fish meal, 9-11 parts of shrimp bran, 7-9 parts of soybean meal, 18-22 parts of peanut meal, 30-35 parts of sub-powder wheat bran, 8-10 parts of corn flour, 6-8 parts of flour, 7-9 parts of soya-bean oil, 1-2 parts of dehydrated locust tree leaves, 1-2 parts of dehydrated spinach and 1-2 parts of feed additive. The preparation method comprises the following steps: the soybean meal and the peanut meal which are inoculated with iron-rich yeast for fermentation are blended with other ingredients according to weight to obtain a feed base-material, and the base-material is subjected to tempering and aging under certain pressure, humidity and temperature by using a biaxial differential conditioner to obtain the product. The feed provided by the invention has the advantages of high feed utilization rate, high destroy rate of anti-nutritional factors, high stability in water and small feed coefficient. After the feed is used for Tilapia mossambica, the pollution of the water quality can be reduced, the survival rate of the Tilapia mossambica can be increased and the feeding cost can be reduced. The fish fed with the feed has good body figure, delicious meat quality and abundant organic iron contents. After people frequently eats the iron-rich fish, the people has enhanced immunity and full energy, after a child frequently eats the iron-rich fish, the child grows rapidly and is intelligent.

Description

technical field [0001] The invention relates to a feed for tilapia, in particular to an iron-rich compound hard pellet feed for tilapia and a preparation method thereof. Background technique [0002] With the application of tilapia farming and supporting technologies, the farming industry of tilapia has developed rapidly, and the consumption of aquatic products is gradually increasing with the improvement of people's living standards. As people pay more and more attention to health, the demand for special aquatic products The demand for tilapia is increasing day by day. At present, peanut meal, wheat and low-quality ordinary hard pellets are commonly used in the farming of tilapia fish. The cost per unit of fish farming is high, the utilization rate is low, there are many residual baits, and the feed coefficient is greater than 1.8- 2. The tilapia hard pellets of ordinary technology have a feeding utilization rate of only about 55-75%, and the feed coefficient is relatively...

AI Technical Summary

Problems solved by technology

Low feed utilization rate and high feed coefficient will lead to more residual bait deposition, resulting in eutrophication of aquaculture water, high nitrogen and phosphorus discharge, heavy water pollution, frequent fish diseases, decreased survival rate, and reduced production , the cost of farming per unit of fish is also higher

At present, there is no public disclosure of hard pellet feed produced in tilapia feed by adding iron-rich fermented feed materials. This requires creative research and testing on raw material components, the content of each raw material component, and suitable production processes. Obtain mature hard pellet feed suitable for tilapia fish feeding, reasonable nutrition, and small feed coefficient
