Problems solved by technology
In addition, studies have shown that the effect of compound organic acids is better than that of single use, but the different combinations and ratio optimization of compound organic acids, the mechanism of promoting growth, and the impact on the body's antioxidant function, immune ability and intestinal microflora are also important. Still needs further research
[0010] At present, acidifiers have not been widely used in aquatic feed, and organic acids suitable for river crabs have not been reported.

Embodiment 1
[0023] A river crab acidified feed, fish meal and meat and bone meal in the feed account for 15% of the feed quality; citric acid accounts for 0.1% of the feed quality, and formic acid accounts for 0.3% of the feed quality; citric acid and formic acid in the feed Add while mixing.
Embodiment 2
[0025] An acidified feed for river crabs, in which fish meal and meat and bone meal account for 10% of the mass of the feed; citric acid accounts for 0.1% of the mass of the feed, and formic acid accounts for 0.2% of the feed; citric acid and formic acid are mixed in the feed join when.
Embodiment 3
[0027] A river crab acidified feed, fish meal and meat and bone meal account for 8% of the feed quality in the feed; citric acid accounts for 0.2% of the feed quality, and formic acid accounts for 0.1% of the feed quality; citric acid and formic acid are in the feed Add while mixing.

The invention discloses a feed for acidizing river crabs, which comprises raw materials and an acidifier, wherein the acidifier is composed of citric acid and formic acid, and accounts for 0.2%-0.4% of the mass of the feed; and fish meal and meat and bone meal in the feed account for 8% of the mass of the feed. The feed disclosed by the invention can obviously reduce the feed coefficient, improves the utilization efficiency of feed phosphor, improves intestinal flora structure of river crabs and enhances immunity of river crabs.
Description
technical field [0001] The invention relates to a feed, in particular to an acidified feed for crabs. Background technique [0002] River crab (scientific name: Chinese mitten crab Erocheir sinensis) It is favored by people because of its delicious meat. It is a unique cultured species in my country, and it is also the freshwater crab with the largest output in China. Statistics from the Fisheries Department of the Ministry of Agriculture show that in 2010, the output of river crab in my country has reached 593,000 tons. River crab farming has high profits and less pollution, so there is a lot of room for development. Since the large-scale artificial breeding of river crab, many important progresses have been made in its nutrition and feed research. At present, the requirements of river crabs for various nutrients have been basically clarified (Ai Chunxiang et al., 2006), and the literature reports on the digestion and utilization of feed materials are also increasing (Zha...
