Feed additive for improving nonspecific immunity and antioxidant ability of river crabs

Abstract

The invention discloses a feed additive for improving the nonspecific immunity and the antioxidant ability of river crabs. Three Chinese herbal medicines including cortex eucommiae, rhizoma chuanxiongand herba houttuyniae and a beneficial bacterium bdellovibrio capable of phagocytizing pathogenic bacteria are matched in a certain proportion to prepare the additive, and the additive is applied toconventional commercially available feed, and thus, the nonspecific immunity and antioxidant indexes of the river crabs can be effectively improved, a large number of prevention and treatment drugs are saved, cost is reduced, drug residues are reduced, and product quality is improved, and meanwhile, the feed additive also has a very good prevention and treatment effect on emerging or unknown diseases.

Description

Technical field [0001] The invention belongs to the technical field of feed additives, and particularly relates to a convenient feed additive for improving the non-specific immunity and antioxidant capacity of river crabs and a preparation and use method thereof. Background technique [0002] Since the breakthrough of artificial breeding technology of river crab in the early 1980s, my country’s river crab breeding industry has developed rapidly. Today, there are more than 20 provinces in the north and south of the country, especially Jiangsu, Anhui, Zhejiang, Jiangxi, Hubei, and the middle and lower reaches of the Yangtze River. Hunan and other provinces have developed various scales of river crab breeding. Due to the rapid expansion of the scale of breeding, the types of river crab diseases are increasing, causing serious losses to farmers. With the rapid development of my country's river crab breeding industry, the breeding area and breeding output continue to increase. It is e...
