[0017] Example
[0018] The technical solutions of the present invention are 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 5-6% of pig blood hydrolysate, 5-6% of soybean meal hydrolysate, 10-15% of fish meal, 25-30% of soybean meal, 20-25% of corn gluten meal, and 5-6 percent of gluten powder. -18%, peanut meal 10-15%.
[0020] For the preparation of the above-mentioned porcine blood hydrolysate, after porcine blood powder is added with water in a weight ratio of 1:7, then add 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. Warm up to 95°C to inactivate the enzyme, and bath in water for 25 minu...
