The invention belongs to the field of livestock slaughtering, and in particular relates to a livestock electric shock device for locating the heart based on the forelimbs and a method for using the same. Two grooves arranged parallel to each other, the two grooves are located between the two fixing plates, a plurality of detection mechanisms are arranged in the groove, and a plurality of detection mechanisms are arranged on the side wall of the groove Compatible fixing mechanism. The invention realizes the fixation of the livestock by the weight of the livestock itself, and after fixing, the position of the heart of the livestock can be judged through the contact position between the livestock and the base, and then electric shocks can be performed near the heart of the livestock through the electric shock element, thereby making the livestock Cardiac arrest leads to rapid death of livestock and reduces the pain suffered by livestock when it dies.

The invention discloses a method for improving the efficiency of killing retained bacteria by aminoglycoside antibiotics through low ion shock. The method comprises the following steps of: preparing antibiotics into an antibiotic pretreatment solution with a certain concentration by adopting an isotonic solution or a sterile aqueous solution, wherein the isotonic solution is a 0.3M glycerol solution or a 0.9% Nacl solution, and the sterile aqueous solution is double distilled water. The antibiotic pretreatment solution is used for carrying out resuspension treatment on bacterial liquid containing retained bacteria to be killed. The method can greatly improve the efficiency of killing the remained bacteria by the aminoglycoside antibiotics, effectively eliminate the retention of bacteria, reduce the tolerance of the bacteria, and reduce the dosage and the administration time on the premise of achieving the same treatment effect, thereby reducing the side effect of the antibiotics.

The invention belongs to the field of water pollution treatment, in particular relates to a water body algae scavenger and a preparation method thereof. A blue algae scavenger taking floatstone as a carrier is characterized in that the blue algae scavenger is prepared by a cerous nitrate solution, a sodium hydroxide solution and lumpish floatstone raw materials, wherein the addition amount of thesodium hydroxide solution is 1 to 5 percent of the volume of the cerous nitrate solution, and the addition of the lumpish floatstone is 5 to 10 percent of the total mass of the cerous nitrate solution and the sodium hydroxide solution; the mass concentration of the cerous nitrate solution is between 0.2 and 0.5 percent, and the mass concentration of the sodium hydroxide solution is between 5 and 10 percent; and the lumpish floatstone is obtained by crushing floatstone into lumps with the diameter between 0.5 and 3 centimeters, stirring and cleaning the lumps for 1.5 to 2.5 hours by the sodiumhydroxide solution with the mass concentration between 8 and 12 percent, cleaning the lumps into neutrality and drying the lumps. The blue algae scavenger prepared by the method has the advantages ofgood blue algae removal effect, quickness in taking effect, low cost and no secondary pollution.
