A Feed for Preventing Abnormal Fat Deposition in Liver Tissue of Grass Carp

Abstract

The invention relates to a feed for preventing grass carp liver tissue fat abnormal deposition. The feed comprises the following ingredients: fish meal, bean meal, vegetable meal, cottonseed meal, DDGS, wheat, bran, bean oil, phospholipid oil, calcium dihydrogen phosphate, choline chloride, pre-mixed material of multiple vitamins and multiple minerals and active complex. On the basis of ensuring nutrition demand of normal physiological growth of the grass carp, the active complex is added to promote growth of the grass carp and reduce the fodder coefficient; moreover, long-time feeding by the feed will not cause pathological changes of abnormal fat deposition in the liver cells of the grass carp, so that the defect of causing grass carp liver tissue fatty degeneration by grass carp feed of the same grade is thereby overcome.

Description

【Technical field】 [0001] The invention relates to a grass carp feed, in particular to a feed for preventing abnormal fat deposition in the liver tissue of grass carp, and belongs to the field of feed processing. 【Background technique】 [0002] Grass carp is a typical herbivorous fish without stomach, which has the advantages of fast growth, tender meat and delicious taste. With the advancement of breeding technology, the high-density intensive farming model has become an important way to achieve breeding efficiency. In the high-density breeding mode, in order to ensure that the yield per mu reaches the expected yield, the nutritional grade requirements to meet the normal physiological growth of grass carp are also relatively high, so under normal circumstances, choose to feed high-protein submerged or high-grade extruded pellet feed It is an important guarantee for annualized breeding benefits. [0003] Practice has shown that feeding grass carp with high-nutritional feed ...

AI Technical Summary

Problems solved by technology

However, due to the unbalanced feed nutrition or the nutrient metabolism disorder of grass carp itself, grass carp fed with high-nutrition grade feed are prone to abnormal fat deposition in liver cells (such as steatosis, etc.), resulting in reduced food intake and poor stress resistance ability of grass carp , poor disease resistance, etc.

[0004] In view of the abnormal fat deposition in grass carp liver cells, reducing feed or switching to low-grade feed has become the main means, but this solution will affect the growth and weight specifications of grass carp, delaying the marketing cycle
