Embodiment

[0018] The technical solution of the present invention will be further explained by the following examples, but the protection scope of the present invention is not limited in any form by the examples.

[0019] The high-efficiency composite protein source of the present invention is composed of pig blood hydrolyzate 5-6%, soybean meal hydrolyzate 5-6%, fish meal 10-15%, soybean meal 25-30%, corn gluten powder 20-25%, gluten powder 5% -18%, peanut meal 10-15%.

[0020] For the preparation of the above-mentioned pig blood hydrolyzate, add water to the pig blood powder in a weight ratio of 1:7, then add two enzymes, Alcalase alkaline protease and Flavourzyme flavor protease, the amount of enzyme can be adjusted to Alcalase1-1.5ml / 100g, Flavourzyme1-1.5g / 100g, the weight ratio of material to water is 1:7, adjust the pH to 8.5-9.0, and hydrolyze at 55°C for 4.5 hours. Raise the temperature to 95°C to inactivate the enzyme, and bathe in water for 25 minutes. Cool, filter, and the...

Abstract

The invention relates to a compound protein source as well as preparation and application thereof, and belongs to the fields of nutrients and feeds of aquatic livestock. The compound protein source is characterized by consisting of the following components in percentage by weight: 5-6% of porcine blood hydrolysate, 5-6% of soybean meal hydrolysate, 10-15% of fish meal, 25-30% of soybean meal, 20-25% of corn protein powder, 5-18% of vital wheat gluten, and 10-15% of peanut meal. Compared with a commercial feed, a feed added with the compound protein source disclosed by the invention has the advantages that the growing performance of bass can be notably improved, the feed factor is reduced, the non-specific immunological competence of organisms is improved, and the consumption of fish meal in the bass feed is reduced.

Description

technical field [0001] The invention belongs to the field of aquatic animal nutrition and feed, and in particular relates to the preparation and application of a composite protein source. Background technique [0002] The most urgent problem brought about by the rapid growth of population is to provide food for human beings. As a kind of high-value food with high protein and low fat in food, people's demand for it is naturally increasing day by day. Protein is the most important nutrient in aquatic animal feed, and it is also the key to the cost of feed. Aquatic animals, especially marine aquatic animals, have high requirements for protein content in feed and are highly dependent on animal protein sources, resulting in generally high feed costs for aquaculture animals (Gatlin et al., 2007). Fishmeal is the main protein source of carnivorous fish feed, and also the main component of feed cost. Due to the increase in demand for fishmeal and relatively stable supply, fishmeal ...
