[0017] The Chinese mitten crab feed additive of the present embodiment includes a concentration of 3.70×10 7 pfu / g Bdellovibrio microcapsules, the concentration is 4.37×10 6 cfu / g Bacillus amyloliquefaciens microcapsules and feed binder, with a purity of 98%, produced by Shanghai Luao Biotechnology Co., Ltd. Chinese mitten crab compound feed, produced by Yangzhou Hongda Feed Co., Ltd. Bdellovibrio microbes The mass ratio of capsules, Bacillus amyloliquefaciens microcapsules and feed binder is 16:1:8.5; 8 soil ponds with an area of 1.8 mu and a water depth of 1.6m are used for Chinese mitten crab breeding.
[0018] The additive method of the present embodiment in the Chinese mitten crab feed is as follows: get respectively 100g Bdellovibrio microcapsules, 100g Bacillus amyloliquefaciens microcapsules, 94.1g Bdellovibrio phage microcapsules+5.9g amylolytic Bacillus microcapsules were added to 1.0L purified water respectively, stirred evenly, and then mixed with 9 kg of Chines...
Embodiment 3
[0021] The Chinese mitten crab feed additive of the present embodiment includes a concentration of 3.69×10 7 pfu / g Bdellovibrio microcapsules, the concentration is 1.91×10 9 cfu / g Bacillus amyloliquefaciens microcapsules and feed binder, with a purity of 98%, produced by Shanghai Luao Biotechnology Co., Ltd. Chinese mitten crab compound feed, produced by Yangzhou Hongda Feed Co., Ltd. Bdellovibrio microbes The mass ratio of capsules, Bacillus amyloliquefaciens microcapsules and feed binder is 16:2:8.5; 8 soil ponds with an area of 2.2 mu and a water depth of 1.8m are used for Chinese mitten crab cultivation.
[0022] In this example, the mass ratio of the mixture of bacteriophage Bdellovibrio microcapsules and Bacillus amyloliquefaciens microcapsules to the Chinese mitten crab feed was 1:11, and the method of adding additives to the Chinese mitten crab feed was the same as in Example 1.
[0023] In the experiment of improving the plumpness of Chinese mitten crabs, the Chine...
