The application discloses a kind of fermented feed fermented by three strains of probiotics of Bacillus YA ( Bacillus sp ), yeast Y ( Saccharomyces cerevisiae ) and capsular red bacteria R3 ( Rhodobacter capsulatus ), and preparation method and application in aquaculture thereof, and viable count is not less than 1×10 7 CFU / g.The fermented feed is replaced ordinary feed according to certain proportion, and feeding result shows that aquaculture water quality is significantly improved after adding fermented feed, and fish growth performance, digestive enzyme activity, immunity, and muscle quality are also obviously improved.Using the feed in suitable range can shorten growth cycle, reduce cost, improve aquaculture environment, reduce antibiotic use, and improve muscle quality of farmed animals, with good economic and ecological benefits, simple fermentation process, low cost, and suitable for industrial large-scale production.

This utility model discloses a farrowing cage for pig farming, specifically relating to the field of pig farming. It includes a mounting base, on one side of which multiple connecting blocks are symmetrically fixedly mounted. The farrowing cage is fixedly mounted between these connecting blocks. Two fixing blocks are symmetrically fixedly mounted on the upper surface of the mounting base, and a driving device is provided between the two fixing blocks. A mounting plate is fixedly mounted on the output end of the driving device. Water collection tanks are fixedly mounted on both sides of the mounting plate, and multiple nozzles are fixedly connected to the bottom of each water collection tank. This utility model, by setting up a driving device, motor, scraping device, and nozzles, achieves a "scraping and flushing combined" cleaning process by having the scraping device, water collection tanks, and nozzles reciprocate through the driving device. This eliminates the need for frequent manual cleaning, reduces labor intensity, and simultaneously reduces bacterial growth caused by fecal residue, effectively improving the farming environment.

This invention discloses a method and its application for enhancing the antibacterial activity of *Propionibacterium f. reudenreichii* subsp. *shermanii* metabolites by adding carrageenan to a semi-solid culture medium. The method uses *Propionibacterium f. reudenreichii* subsp. *shermanii* NBRC No. 12426 as the experimental strain and *Pichia anomala* SICC 2.894 as the indicator strain. It discloses a method for enhancing the antibacterial activity of *Propionibacterium f. reudenreichii* subsp. *shermanii* metabolites against the indicator strain *Pichia anomala* by adding carrageenan to the culture medium. Based on the culture conditions and method of *Propionibacterium f. reudenreichii* subsp. *shermanii* in this invention, the optimal amount of carrageenan added is selected as 0.6%, which significantly enhances the antibacterial activity of the *Propionibacterium f. reudenreichii* subsp. *shermanii* metabolites.

The utility model relates to the technical field of breeding cage, disclose a kind of egg breeding cage with protective function, including chicken coop, and several groups of fixed mechanism are symmetrically equipped in chicken coop inner wall, and the fixed mechanism between each group of symmetrically arranged is equipped with mesh and collecting plate in upper and lower distribution, and disinfection assembly is equipped in chicken coop inside mesh and collecting plate outside;Fixed mechanism includes two sliding rails of side by side arrangement, and sliding rail is fixedly connected with chicken coop inner wall, and sliding plate is slidably installed in sliding rail, and the upper two sliding plates are fixedly connected with mesh, and the lower two sliding plates are fixedly connected with collecting plate, and collecting plate top is equipped with flow guide groove, and chamber is equipped in sliding plate front end inside, and torsion bar is rotatably installed in chamber, and one end of torsion bar extends to the outside of sliding plate and is connected with handle;The utility model can improve space utilization, optimize breeding environment and protect chicken health by flexible adjustment space through fixed mechanism, feces is handled using collecting plate, and sterilization is assisted by disinfection assembly.

This utility model relates to the field of bass farming technology, specifically to an aeration device for bass farming ponds with adjustable water flow direction. It includes an adjustment component and a cleaning component. The adjustment component consists of a fixed plate, an adjustment plate, a rotating shaft, a connecting belt, a rotating rod, and a servo motor. The rotating shaft is rotatably connected to the inner wall of the fixed plate, and the adjustment plate is fixedly connected to the outer surface of the rotating shaft. The connecting belt is provided on the upper surface of the rotating shaft. This aeration device for bass farming ponds with adjustable water flow direction, through the arrangement of the fixed plate, adjustment plate, rotating shaft, connecting belt, rotating rod, and servo motor, allows the operator to activate the servo motor during aeration. The servo motor drives the rotating rod to rotate, which in turn drives the rotating shaft to rotate, which in turn drives the connecting belt to rotate, allowing the rotating shaft to adjust the angle of the adjustment plate, thus changing the oxygen supply angle.
