Zinc-enriched formulated hard palletized feed for carp and preparation method thereof

Abstract

The invention discloses a zinc-enriched formulated hard palletized feed for carp, comprising such components, by weight, as: 6-8 of zinc-enriched fermentation material, 10-15 of sunflower cake, 10-15 of peanut cake, 10-15 of flour, 3-5 of bran, 4-6 of pea powder, 5-10 of rice bran, 1-2 of mineral premix, 0.2-0.3 of vitamin premix, 1.5-2 of calcium dihydrogen phosphate, 1.5-3.5 of fish oil, 1-2 of chalk, and 0.01-0.02 of rhizoma polygonati polysaccharide. The preparation method comprises inoculating zinc-enriched yeast to soy bean meal and / or peanut meal and fermenting, formulating a base feed by mixing the fermented materials with other components according to the weight parts, and conditioning and ripening the base feed at a certain pressure, humidity, and temperature by using a double-shaft differential conditioner to acquire the zinc-enriched formulated hard palletized feed; the feed of the invention has the advantages of high feed utilization rate, high destruction rate of anti-nutritional factors, high stability in water, and small feed coefficient. Water pollution can be reduced, the survival rate of the carp can be increased, and feed cost can be reduced by feeding the carp with the feed of the invention. Furthermore, grown carp fed by the feed are in good shape, have delicious fish meat, contain abundant organic zinc, can eliminate free radicals in the body, and play a role of health care for human health.

Description

technical field [0001] The invention relates to a carp feed, in particular to a carp zinc-enriched compounded hard granular feed and a preparation method thereof. Background technique [0002] With the application of carp farming and supporting technologies, the carp farming industry is developing rapidly. With the improvement of people's living standards, the consumption of aquatic products is gradually increasing. As people pay more and more attention to health, the demand for special aquatic products is increasing. Increase. At present, peanut meal, wheat and low-quality ordinary hard pellets are commonly used in the breeding of carp. The unit fish breeding cost is high, the utilization rate is low, there are many residual baits, and the feed coefficient is greater than 1.8-2. The carp hard granules of ordinary technology have a feeding utilization rate of only about 55-75%, and the feed coefficient is relatively large, which is above 2.0. Low feed utilization rate and h...

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 carp feed by adding zinc-rich fermented feed raw materials. This requires creative research and experiments on raw material components, the content of each raw material component, and suitable production processes. Matured hard pellet feed for carps that feed on carps with reasonable nutrition and low feed coefficient
