Embodiment 1

[0022] Example 1: The raw material composition of shrimp compound feed and its content by mass percentage are fish meal 8%, soybean meal 20%, corn gluten meal 7.5%, brewer's yeast 2%, chicken meal 9%, meat and bone meal 9%, blood meal 4.5% , squid viscera powder 3%, shrimp bran powder 5%, soybean lecithin 2%, fish oil 1%, calcium dihydrogen phosphate 2%, feed additive premix 1% (of which, prawn multidimensional premix 0.1%, prawn compound trace 0.2% elemental premix, 0.1% taurine, 0.2% betaine, 0.05% vitamin C, 0.15% choline chloride, 0.2% wheat bran), 26% subflour. During the preparation, the raw materials are pulverized, passed through a 60-mesh sieve, mixed and granulated to prepare the shrimp compound feed.

[0023] The comparative feeding experiment 1 of shrimp compound feed is given below. Using the above-mentioned feed formula, a compound feed with high protein level and low fishmeal was prepared, and the feeding effect test of Penaeus white shrimp was carried out. Pr...

Embodiment 2

[0034] Similar to Example 1, the difference is that the raw material composition of the shrimp compound feed and its content by mass percentage are fish meal 8%, soybean meal 25%, corn gluten meal 10%, brewer's yeast 3%, chicken meal 15%, meat and bone meal 7% %, spray-dried blood meal 3%, squid viscera powder 4%, shrimp bran powder 4%, soybean lecithin 1.5%, fish oil 1%, calcium dihydrogen phosphate 1.5%, feed additive premix 1% (among them, prawn multidimensional premix 0.06% of raw material, 0.1% of prawn compound trace element premix, 0.2% of taurine, 0.3% of betaine, 0.04% of vitamin C, 0.2% of choline chloride, 0.1% of wheat bran), and 16% of subflour. During preparation, each raw material after pulverization is passed through a 60-mesh sieve.

Embodiment 3

[0036] Similar to Example 1, the difference is that the raw material composition of the shrimp compound feed and its content by mass percentage are 10% fish meal, 23% soybean meal, 7% corn gluten meal, 2% brewer's yeast, 5% chicken meal, and 6% meat and bone meal. %, spray-dried blood meal 2%, squid viscera powder 3%, shrimp bran powder 6%, soybean lecithin 1%, fish oil 1.5%, calcium dihydrogen phosphate 1%, feed additive premix 1.5% (among them, prawn multidimensional premix 0.1% of raw material, 0.125% of prawn compound trace element premix, 0.4% of taurine, 0.2% of betaine, 0.02% of vitamin C, 0.1% of choline chloride, 0.555% of wheat bran), and 31% of secondary flour. During preparation, each raw material after pulverization is passed through a 60-mesh sieve.

Abstract

A shrimp compound feed and a preparation method thereof relate to a feed. The invention provides the shrimp compound feed with balanced nutrition and high quality and the preparation method thereof. The raw materials are as follows: 7 percent-12 percent of fish meal, 15 percent-25 percent of soybean meal, 5 percent-10 percent of corn protein powder, 2 percent-5 percent of beer yeast, 5 percent-15 percent of chicken powder, 6 percent-12 percent of meat bone powder, 2 percent-6 percent of spray-dried blood meal, 3 percent-5 percent of squid visceral meal, 4 percent-8 percent of shrimp bran powder, 1 percent-2 percent of soybean lecithin, 1 percent-2 percent of fish oil, 1 percent-2 percent of calcium dihydrogen phosphate, 1 percent-2 percent of feed additive premix and the balance of wheat middling. The various raw materials are smashed, screened, mixed and granulated. The sources of animal and plant protein raw materials are wide, the yield is high, and the stable supply can be ensured; the reasonable match of the fish meal and the soybean meal can reduce the protein content of the fish meal in the shrimp feed to be lower than 9 percent or reduce the using proportion of the fish meal to be lower than 12 percent; the shrimp compound feed can improve the feed palatability, improve the feed intake of shrimps and be used for the intensive culture of the shrimps.

Description

technical field [0001] The invention relates to a feed, in particular to a low-fishmeal compound feed for growing shrimp and a preparation method thereof. Background technique [0002] So far, fishmeal is still the most important protein raw material in aquafeed, but the world's fishmeal production has not increased significantly for a long time, and the rapid development of aquaculture industry has promoted the strong demand for fishmeal in the aquafeed industry, resulting in a serious shortage of fishmeal supply. In order to alleviate the contradiction between supply and demand of fishmeal and reduce the excessive dependence of aquaculture industry on fishmeal, research and development of fishmeal substitutes and their preparation technology is a realistic way to fundamentally alleviate the shortage of fishmeal supply and reduce feed costs. For this reason, major aquaculture countries in the world are actively carrying out research on fishmeal substitutes. Although some pr...
