Compared with the high-moisture straws eaten by the flocks and herds, the low-moisture straws eaten by the flocks and herds can obviously reduce the happening rate of acidosis and diarrhea of the flocks and herds.

The invention provides a method for managing experimental animal respiration, which utilizes a clinic anesthesia machine for the anesthetization of the animal experiment, performs tracheal cannula on an animal, adopts an animal temperate maintenance instrument to keep warm, and keeps the body temperature at the physical level (37 plus or minus 0.5 DEG C) all the time during the anesthesia process. The method is used for solving the animal respiration management problem during the traditional anesthesia process, the same inhalation anesthesia concentration and the stable body environment are also maintained during the whole anesthesia process. By the method, not only is the stress response of the experimental animal reduced, but also the vital sign stability of the experimental animal can be maintained during the inhalation anesthesia process of a long time (such as 4 hours), the mortality is low and the reviving can be stable, and the influences of trauma stress, hypoxia-ischemia, hypercapnia, acidosis and other interference factors on the experimental result can be eliminated. The method effectively controls the respiratory tract of the experimental animal, and also maintains the inhalation anesthesia of the volatile anesthetics with constant concentration, which is output to the animal.

The invention relates to drinking water with hydrogen or deuterium, and a preparation method thereof, and belongs to the technology field of drinking water. The drinking water with hydrogen or deuterium is made by adding pure hydrogen or deuterium into pressurized drinking water. The preparation method comprises the steps of reducing the temperature of drinking water in a high pressure vessel to 0 DEG C-5DEG C, and increasing the pressure in the vessel to 1.2-1.5atm; adding the pure hydrogen or deuterium to increase the solubility of the hydrogen or the deuterium to 30mL/L. The drinking water with hydrogen or deuterium can enable a person to ingest protium which is good for human body when the person drinks the drinking water with hydrogen or deuterium, thereby improving the metabolism of the human body, smashing causal active oxygen (free radical) which causes diseases, strengthening nature curability of birth of the human body, activating organs, improving natural immunity of the human body, enabling waste in vivo to quickly discharge, delaying aging and improving acidosis of the human body. The drinking water with hydrogen or deuterium is new concept drinking water, which has definite functions, good taste and suitability for both the old and the young.
