Embodiment 1

[0009] Embodiment 1: A kind of aquatic feed based on cottonseed meal, the components include by percentage: cottonseed meal 5.76%, fish meal 30.24%, soybean meal 15%, sunflower meal 14.75%, standard powder 20%, multivitamin 0.5%, compound Minerals 2.0%, ferrous sulfate 0.05%, lysine 0.3%, calcium dihydrogen phosphate 0.6%, stone powder 3.0%, rapeseed oil 2.3%, carrier 5.5%.

[0010] The carrier is attapulgite clay.

[0011] In terms of nitrogen and phosphorus, pepsin-trypsin two-step enzymolysis method was used to measure the in vitro digestion of feed. The result showed that the digestibility of protein was 58.03%, and the digestibility of phosphorus was 35.47%.

Embodiment 2

[0012] Example 2: 21.6% of cottonseed meal, 14.4% of fish meal, 15% of soybean meal, 14.75% of sunflower meal, 20% of standard powder, 0.5% of multivitamin, 2.0% of multivitamin, 2.0% of multivitamin, 0.1% of ferrous sulfate, 0.4% of lysine , calcium dihydrogen phosphate 1%, stone powder 4.95%, rapeseed oil 2.3%, carrier 3%.

[0013] The carrier is attapulgite clay.

[0014] In terms of nitrogen and phosphorus, pepsin-trypsin two-step enzymolysis method was used to measure the in vitro digestion of feed. The result showed that the digestibility of protein was 60.29%, and the digestibility of phosphorus was 39.52%.

[0015] Embodiment: 3: a kind of aquatic feed based on cottonseed meal, component comprises by percentage: cottonseed meal 12%, fish meal 24%, soybean meal 15%, sunflower kernel meal 14.75%, standard powder 20%, multivitamin 0.5%, Compound minerals 2.0%, ferrous sulfate 0.05%, lysine 0.4%, calcium dihydrogen phosphate 0.8%, stone powder 2.0%, rapeseed oil 2.3%, car...

Abstract

A cottonseed meal-based aquatic product feed comprises 5.76-21.6% of cottonseed meal, 14.4-30.24% of fish meal, 15% of soybean meal, 14.75% of sunflower seed kernel powder, 20% of standard flour, 0.5% of composite vitamins, 2.0% of composite mineral matters, 0.05-0.1% of ferrous sulfate, 0.3-0.4% of lysine, 0.6-1% of calcium dihydrogen phosphate, 2.0-4.95% of stone flour, 2.3% of rapeseed oil and 3.0-6.2% of a carrier. Ferrous sulfate is added to the feed, and iron ions react with gossypol in small intestines of animals to form a stable complex, so absorption and entrance of gossypol to blood are prevented, the biologic validity of lysine is improved, the survival rate of fish and the protein digestion rate are improved, lysine is extra supplemented, and balanced nutrition is provided for growth of the fish.

Description

technical field [0001] The invention relates to a feed, in particular to an aquatic feed based on cottonseed meal. Background technique [0002] Aquafeed is a green feed with rich and balanced nutrition, no antibiotics, good stability, and high absorption and utilization rate. Protein and phosphorus are two important factors in the formula of aquafeed, which provide essential nutrients for fish growth. Fishmeal is The main protein source of traditional aquatic feed, but the phosphorus content of fish meal is high, phosphorus is not easy to be used by fish and shrimp, and a considerable amount of phosphorus will be discharged into the water body with the metabolites of fish, which is easy to cause eutrophic water body, and the price of fish meal is relatively expensive , is no longer the best source of protein in aquatic feed. The protein content in cottonseed meal is equivalent to that of fishmeal, with a wide range of sources and low price, so cottonseed meal has been used...
