Compound feed used for tilapia mossambica breeding and preparation method thereof

Abstract

The invention provides a compound feed used for tilapia mossambica breeding. Per 992-999 parts by weight of the compound feed used for the tilapia mossambica breeding comprises the Chinese herbal medicine extracts prepared from the following Chinese herbal medicines in parts by weight: 0.005-0.025 part of radix astragali, 0.005-0.020 part of dried orange peel, 0.005-0.015 part of Chinese angelica roots, 0.005-0.025 part of radix sophorae flavescentis, 0.003-0.015 part of poria cocos, 0.005-0.030 part of honeysuckle flowers, 0.005-0.020 part of skullcaps, 0.005-0.025 part of mugwort leaves, and 0.005-0.015 part of fennels. The Chinese herbal medicine compound used in the compound feed disclosed by the invention also has the functions of attracting, promoting growth and enhancing non-specific immunity of the body, and is capable of promoting growth performances of the tilapia mossambica in difference stages, improving feed utilization rate, and enhancing non-specific immunity and disease resistance of the tilapia mossambica. Moreover, the invention further provides a compound feed prepared by the preparation method. The invention relates to the technical field of aqua-feeds.

Description

technical field [0001] The invention relates to the technical field of fish feed, in particular to a compound feed for tilapia cultivation and a preparation method thereof. Background technique [0002] With the intensive development of aquaculture, the scale of tilapia farming continues to expand, and the breeding density and production continue to increase. However, with the expansion of tilapia farming scale, increasing stocking density, over-feeding and use of low-quality feed, the water environment of tilapia farming is deteriorating, diseases are becoming more frequent and serious, and muscle quality is declining, which has become a constraint for tilapia farming. One of the important factors for the healthy development of the industry. Since 2009, tilapia streptococcal disease broke out in southern China. In 2012, the largest streptococcal disease outbreak in southern China ever occurred. Tilapia production was reduced in a large area, and the aquaculture output decl...

Problems solved by technology

However, the addition of these prohibited antibiotics not only leads to excessive detection of drug residues in tilapia muscle and hinders export, but also affects the deposition of nutrients such as feed protein and fat in muscle, and the sustainable development of tilapia aquaculture industry is seriously hindered

[0003] Therefore, in order to solve the problems such as the decrease of meat quality and the decrease of meat yield caused by the degradation of current tilapia seed resources, the drug residue and the decrease of muscle quality caused by the abuse of sulfonamide antibiotics in the breeding process, it is urgent to develop a nutritious, green, environmentally friendly, A green and healthy compound feed that can promote the healthy growth of tilapia, improve feed utilization and meat yield, enhance the body's non-specific immunity, and improve the muscle quality of tilapia
