Problems solved by technology

At present, some Chinese herbal medicines, such as comfrey and Achyranthes bidentata, are used to improve the plumpness of Chinese mitten crabs, but the effect is slow, usually at least one month before the effect of improving the plumpness of Chinese mitten crabs can be achieved (Chen Chengxun, et al. Effects of Zicao and Achyranthes chinensis on the growth and antioxidant indicators of Chinese mitten crab. Sun Xueliang, et al. The effects of three compound Chinese herbal medicines on the growth and some antioxidant indicators of Chinese mitten crab), which not only greatly increased the farmers’ The cost of use, and the effect of Chinese herbal medicine is not stable due to the influence of multiple factors such as region and time.

Abstract

The invention discloses an eriocheir sinensis feed additive and a method for improving the fatness of eriocheir sinensis by using the same. The additive comprises a bdellovibrio bacteriovorus microcapsule with the concentration of 3.69*10<7> pfu / g to 3.70*10<7> pfu / g, a bacillus amyloliquefaciens microcapsule with the concentration of 4.37*10<6> cfu / g to 1.91*10<9> cfu / g and a feed bonder, whereinthe mass ratio of the bdellovibrio bacteriovorus microcapsule to the bacillus amyloliquefaciens microcapsule to the feed bonder is 16:(1-4):(8.5-10). The invention furthermore provides the method forimproving the fatness of the eriocheir sinensis by using the additive. The additive disclosed by the invention is faster in effect taking and more remarkable in effect, and the application and popularization of the additive is more beneficial for improving the quality and market competitiveness of the eriocheir sinensis, reducing the breeding cost of farmers, increasing the breeding benefit and relieving the secondary pollution of chemical disinfectants to aquaculture water.

Description

technical field [0001] The invention relates to a feed additive and a method for improving the plumpness thereof, in particular to a feed additive for Chinese mitten crabs and a method for improving the plumpness of the Chinese mitten crab. Background technique [0002] Eriocheir sinensis is a very important commercial crab in my country and is deeply loved by consumers. Because of its delicious meat quality and unique flavor, it has become an indispensable delicacy on the table. The quality of Chinese mitten crab directly affects its competitiveness in the market, and the quality of Chinese mitten crab mainly depends on its plumpness. At present, some Chinese herbal medicines, such as comfrey and Achyranthes bidentata, are used to improve the plumpness of Chinese mitten crabs, but the effect is slow, usually at least one month before the effect of improving the plumpness of Chinese mitten crabs can be achieved (Chen Chengxun, et al. Effects of Zicao and Achyranthes chinen...
