Embodiment 1
[0014] A compound feed for California perch in which yeast hydrolyzate replaces fish meal, which is composed of the following raw materials in terms of mass percentage: 15% fish meal, 15% pea protein powder, 10% soybean meal, 5% krill meal, 15% gluten powder, and 1 lecithin %, fish oil 5%, premix 1%, flour 25%, secondary flour 1%, lysine 0.5%, methionine 0.4%, threonine 0.1%, yeast hydrolyzate 6%. The purity of the lysine and methionine are both above 98%.
Embodiment 2
[0016] A compound feed for California perch in which yeast hydrolyzate replaces fish meal, which is composed of the following raw materials in terms of mass percentage: 17% fish meal, 10% pea protein powder, 13% soybean meal, 1% krill meal, 10% gluten powder, and 5% phospholipid %, fish oil 10%, premix 5%, flour 15%, secondary flour 5%, lysine 3%, methionine 1%, threonine 1%, yeast hydrolyzate 4%. The purity of the lysine and methionine are both above 98%.
Embodiment 3
[0018] A compound feed for California perch in which yeast hydrolyzate replaces fish meal, which is composed of the following raw materials in terms of mass percentage: 22% fish meal, 10% pea protein powder, 15% soybean meal, 3% krill meal, 10% gluten powder, and 3% phospholipid %, fish oil 7%, premix 3%, flour 15%, secondary flour 3%, lysine 1.5%, methionine 0.1%, threonine 0.4%, yeast hydrolyzate 7%. The purity of the lysine and methionine are both above 98%.

Abstract
The invention provides a micropterus salmoides mixed feed with yeast hydrolysate replacing fish meal. The micropterus salmoides mixed feed comprises 15-22 percent of the fish meal, 10-15 percent of pea protein powder, 10-15 percent of bean pulp, 1-5 percent of krill powder, 10-15 percent of gluten, 1-5 percent of phospholipid, 5-10 percent of fish oil, 1-5 percent of premix, 15-25 percent of flour, 1-5 percent of wheat middling, 0.5-3 percent of lysine, 0.1-1 percent of methionine, 0.1-1 percent of threonine and 1-8 percent of the yeast hydrolysate. The use amount of the fish meal is decreased, the cost is reduced, and the economic benefit of a farmer is increased; in addition, the ratio of liver weight and body weight can be reduced, and the intestinal and liver functions of micropterus salmoides are improved.
Description
【Technical field】 [0001] The invention relates to a feed, in particular to a California perch compound feed in which yeast hydrolyzate replaces fish meal, and belongs to the field of feed processing. 【Background technique】 [0002] California perch, formerly known as largemouth bass, belongs to Perciformes and Sunfish family in taxonomy. It is native to the Mississippi River system in California, USA. rare carnivorous fish. Shenzhen, Huiyang, Foshan and other places in Guangdong, my country also introduced California perch fry in 1983, and succeeded in artificial breeding in 1985. The bred fry have been introduced to Jiangsu, Zhejiang, Shanghai, Shandong and other places for breeding, and all of them have achieved good economic benefits. However, largemouth bass is a typical freshwater carnivorous fish, and the feed penetration rate is low. So far, no nutritionally balanced full-price special feed has been successfully developed. The use of feed throughout the whole proce...
