Problems solved by technology

Polysaccharides and trace elements have high nutritional health and pharmacological activities, especially chromium and selenium, but the existing immunomodulators cannot contain chromium and selenium at the same time, and the content of trace elements in immunomodulators is unreasonable, which can easily lead to animal The balance of trace elements in the body is disrupted and growth is inhibited
Moreover, in the preparation of pumpkin polysaccharide complexes, chromium and selenium have antagonistic effects, and it is difficult to ensure that the two trace elements have a high content at the same time.
[0004] In addition, although the abuse of antibiotics has been effectively controlled at present, the irregular use of antibiotics has caused the original microbial imbalance in the intestinal tract of prawns and made them resistant to antibiotics. Prolonged use will reduce immunity. , Green and environmental protection, pre-mixed feed that can promote the digestion and growth of prawns, has important theoretical and practical significance for the sustainable development of prawn aquaculture

Abstract

The invention relates to the technical field of aquaculture and feed, and particularly provides prawn compound premix feed as well as a preparation method and application thereof. The invention provides the prawn compound premix feed on the first hand, and the prawn compound premix feed at least comprises the following preparation raw materials in parts by weight of 8-12 parts of vitamins, 6-10 parts of minerals, 10-20 parts of a pumpkin polysaccharide-chromium-selenium complex and 60-80 parts of a compound plant preparation. Prawns are good in digestion, high in disease resistance, high in survival rate and remarkable in culture benefit.

Description

technical field [0001] The invention relates to the technical field of aquaculture and feed, and more specifically, the invention provides a compound premixed feed for prawns and its preparation method and application. Background technique [0002] Prawns belong to the phylum Arthropoda, class Mollusca, decapod, prawnidae, and genus Penaeus. Because of its tender meat and rich nutrition, it is deeply loved by consumers. Especially in recent years, along with the rapid development of my country's economy and the continuous improvement of people's living standards, various prawn products have gradually entered the table of ordinary people. At the same time, the rise of tourism and the growth of foreign trade have further promoted the development of my country's shrimp farming and processing industries. Feed is an indispensable material condition for the shrimp farming industry, which provides a strong support for the development of the shrimp farming industry. The continuou...
