Problems solved by technology

[0003] Due to the high level of intensive farming, the existing feed has problems such as unbalanced nutrition, poor food attraction, poor stability in water, and overuse of antibiotics, which have led to a decline in the overall quality of cultured Penaeus vannamei in recent years, slow growth, weak disease resistance, and poor survival. The problem of low rate

Abstract

The invention provides special feed for penaeus vannamei breeding and a preparation method thereof. The special feed for penaeus vannamei breeding is characterized in that the feed comprises 25-33 wt% of fish meal, 10-20 wt% of wheat bran, 15-25 wt% of fermented soybean meal, 15-25 wt% of fermented rapeseed meal, 1-2 wt% of fish oil, 0.5-1.5 wt% of monocalcium phosphate, 1-1.5 wt% of granulesten,0.2-0.5 wt% of composite vitamins for shrimps, 0.2-0.5 wt% of composite mineral matter for shrimps, 0.5-1.0 wt% of bacillus subtilis powder, 5-10 wt% of candida utilis powder, and 0.5-1.0 wt% of zeolite powder. The preparation method comprises the following steps: pulverizing the raw materials respectively, sieving by a sieve of above 90 meshes, mixing proportionally, and performing granulation. The advantages of invention are that: the nutrition is balanced; the palatability is strong; and the feed can increase the survival rate and weight gain rate of penaeus vannamei.

Description

technical field [0001] The invention relates to a special feed for the culture of Penaeus vannamei and a preparation method thereof, belonging to the technical field of feed. Background technique [0002] Vannamei Boone (Penaeus vannamei Boone, 1931), commonly known as: also known as white leg shrimp (white leg shrimp), white shrimp (white shrimp). Penaeus vannamei is one of the three largest shrimp species with the highest aquaculture production in the world today. Penaeus vannamei is native to the Pacific coast of South America. Professor Zhang Weiquan of the Institute of Oceanology, Chinese Academy of Sciences first introduced this shrimp from the United States. At present, Guangdong, Guangxi, Fujian, Hainan, Zhejiang, Shandong, Hebei and other provinces or autonomous regions have gradually promoted breeding. The vannamei cultured in Yangjiabo Town, Hangu District, Tianjin is world-famous and has the reputation of "the hometown of fish and shrimp in China". Among them, ...
