Feed for regulating intestinal health of micropterus salmoides

Abstract

The invention discloses feed for regulating intestinal health of micropterus salmoides. The feed is prepared from the following raw materials in parts by weight: 200-450 parts of fish meal, 80-200 parts of rice protein powder, 20-80 parts of casein, 100-300 parts of soybean meal, 50-100 parts of high gluten flour, 20-100 parts of fish oil, 10-30 parts of mineral premix, 10-30 parts of vitamin premix, 5-30 parts of a phagostimulant and 10-100 parts of a fermentation material. The feed has the beneficial effects that as for the micropterus salmoides fed by the feed, the intestinal development situation is significantly improved, the survival rate and the weight gain rate are significantly increased, and the feed efficiency is significantly improved.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a feed for regulating the intestinal health of California perch. Background technique [0002] The scientific name of California perch is largemouth bass. It is a rare carnivorous fish with delicious meat, strong disease resistance, rapid growth and wide temperature adaptability. It is loved by consumers because of its tender meat and delicious taste. In recent years, the production of perch farming in California has been increasing steadily, especially in Guangzhou and Zhejiang, and it is also developing to other areas, and the breeding benefits are very high. With the rapid development of the California perch farming industry, farming problems have also been highlighted. [0003] At present, the breeding of California perch is still mainly fed with chilled small miscellaneous fish, and the use of artificial compound feed is limited mainly because the utilization rate of fa...

AI Technical Summary

Problems solved by technology

[0003] At present, the breeding of California perch is still mainly fed with chilled small miscellaneous fish, and the use of artificial compound feed is limited mainly because the utilization rate of fat and sugar in the feed is low, and the unreasonable formula structure can easily cause liver and intestinal diseases. Affect farming benefits

At present, animal protein raw materials with high digestibility and utilization are still the main ingredients in commercial feed, so the feed cost is relatively high, and the lack of global marine fish resources and the increasing demand for fishmeal further limit the promotion of California perch feed

The use of plant-based protein raw materials to replace fish meal has become a key point to break through the rapid development of the California perch feed industry, but the anti-nutritional factors of plant-based raw materials will directly affect the intestinal microbial balance and intestinal development of fish, resulting in growth stagnation, A series of intestinal disease emergencies such as intestinal development damage and lesions, and the current lack of clarity on the feeding characteristics and nutritional requirements of California perch have greatly restricted the large-scale breeding of California perch
