Problems solved by technology

Although these protein sources have played a certain role in replacing fishmeal, some unfavorable factors of their own, such as amino acid imbalance and poor palatability, etc., once added in excess, will affect the growth and survival rate of aquatic animals. Cause damage to the tissues of aquatic animals, and even affect the flavor and quality of aquatic products
[0004] So far, most studies are still only on the application effect of a single protein source on the breeding effect, and there are few reports on the replacement of fish meal content in feed by a reasonable combination of several animal and plant protein sources

Embodiment 1

[0010] From May to July, 2010, the feeding experiment in the cement pond of Zhanjiang City, Guangdong Province showed that in the culture cycle (2 months) of Litopenaeus vannamei, 60% and 80% of the fish meal protein in the formula were replaced by composite protein, and when the experiment ended, Vannamei The average weight gain rate and feed coefficient of Penaeus prawns had no adverse effects.

[0011] Comparison of the growth performance of Litopenaeus vannamei in Zhanjiang City, Guangdong Province on the 60th day fed with 60% and 80% fishmeal protein feeds replaced by compound protein

[0012]

[0013] Explanation: The "control group" used 27% fishmeal in the Litopenaeus vannamei feed; the compound protein in the compound 60 group replaced 60% of the fish meal protein; the compound protein in the compound 80 group replaced 80% of the fish meal protein.

Abstract

The invention discloses a compound protein source for litopenaeus vannamei and a preparation method. The compound protein source is formed by mixing three protein raw materials of different sources, namely corn protein powder serving as plant protein, imported chicken powder serving as animal protein and Xin peptide protein powder serving as insect protein in a ratio of 1:2:2 and 1.37 percent of crystal lysine; and the necessary amino acid content of the compound protein source reaches or exceeds the necessary amino acid content of fish meal, so the compound protein source can effectively substitute 60 to 80 percent of fish meal protein in litopenaeus vannamei feed and does not produce adverse influence on the growth of the litopenaeus vannamei. The compound protein source can effectively substitute 60 to 80 percent of fish meal protein in the litopenaeus vannamei feed and does not affect the growth of the litopenaeus vannamei; and the consumption of the fish meal in the litopenaeus vannamei feed is reduced, and the cost of the formula is saved. The weight increment rate of the litopenaeus vannamei is improved. The compound protein source has no any adverse influence on the palatability of the feed and the culture environment; and the raw materials have stable sources and are low in cost, and the production process is simple.

Description

technical field [0001] The invention relates to a compound protein source for Litopenaeus vannamei and a preparation method thereof. technical background [0002] Litopenaeus vannamei (Litopenaeus vannamei) has become a popular species because of its strong disease resistance, fast growth, adaptability to culture in low-salinity waters, delicious meat, relatively low requirements for feed protein, and easy high-density intensive culture. It is one of the three excellent varieties with the highest breeding yield in the world. [0003] Fishmeal has always been the most expensive protein source in aquafeed. In recent years, with the rapid development of aquaculture industry, the demand for fishmeal is also increasing. With the increase of the consumption of fishmeal, the situation that its supply exceeds the demand is more and more obvious, which leads to the continuous rise of the price of fishmeal, followed by the increase of feed cost, which seriously restricts the rapid de...
