Producing method of stress reliever

Abstract

Provided is a method of producing a stress reliever that reduces a decrease in productivity of livestock at the time of stress load by feeding the stress reliever to the livestock. The method of producing the stress reliever includes solid-culturing a substrate with the filamentous bacteria, in which the stress reliever reduces a decrease in productivity of livestock at the time of stress load.

1 . A method of producing a stress reliever, the method comprising:
 solid-culturing a substrate with filamentous bacteria to obtain a solid-cultured product, wherein   the stress reliever reduces a decrease in productivity of livestock at the time of stress load.   
     
     
         2 . The method of producing the stress reliever according to  claim 1 , wherein the produced stress reliever reduces one or more decreases in productivity of livestock at the time of stress load by relieving stress of livestock ingesting, the stress reliever, the one or more decreases being among body weight reduction, a decrease in an ingestion amount of feedstuff, a decrease in an egg weight, a decrease in an eggshell thickness, and a decrease in a yolk weight. 
     
     
         3 . The method of producing the stress reliever according to  claim 1 , wherein the filamentous bacteria are bacteria not producing mold poison. 
     
     
         4 . The method of producing the stress reliever according to  claim 3 , wherein the bacteria not producing mold poison are filamentous bacteria among  Aspergillus oryzae, Aspergillus sojae, Aspergillus luchuensis, Aspergillus niger,  or  Aspergillus awamori  not producing mold poison. 
     
     
         5 . The method of producing the stress reliever according to  claim 1 , wherein the solid-cultured product comprises polysaccharides constituting hyphae of the filamentous bacteria. 
     
     
         6 . The method of producing the stress reliever according to  claim 1 , wherein the solid-cultured product comprises an enzyme having activity. 
     
     
         7 . The method of producing the stress reliever according to  claim 1 , wherein the solid-cultured product comprises viable bacteria of the filamentous bacteria. 
     
     
         8 . The method of producing the stress reliever according to  claim 1 , further comprising: determining the solid-cultured product alone obtained by solid-culturing the substrate with the filamentous bacteria to be the stress reliever or determining the solid-cultured product obtained by solid-culturing the substrate with the filamentous bacteria and blended with a feeding substance to be the stress reliever.
