Abstract: Seasoning of liquid material containing at least sodium chloride, seasoning components and solvent is dried at a temperature not more than the boiling temperature of the liquid material to generate mixture bodies containing large-diameter spherical bodies and small-diameter spherical bodies. Accordingly, the solvent is not rapidly vaporized, but it is slowly vaporized and components dissolved in water, and particularly sodium chloride is not agglomerated on the surface layer portions of the large-diameter spherical bodies, but kept inside the large-diameter spherical bodies. Therefore, segregation of sodium chloride on the surface layer portions can be suppressed, and deliquescence is reduced. Accordingly, there can be obtained dry powder seasoning which is low in deliquescence under a using state and excellent in storage stability for a long term.

Abstract: A fish culturing method and a sac-fry pond for practicing the method are disclosed, which utilize irradiation of far infrared rays from above the water surface in a culturing pond and/or from the bottom of the pond to promote growth of fry in water of a relatively low temperature, substantially without raising the temperature of water which is consumed in a great amount.

Abstract: A method of promoting growth of a great number of livestock individuals to the prescribed average weight in a substantially closed house, within a reduced period of time and consumption of feed, at an enhanced rate of survival and at a suppressed degree of variation in the individual growth, which comprises heating the house floor from below and controlling the floor temperature to be substantially constant throughout the floor area, and effecting ventilation across the house substantially without generation of any noise by delivering outdoor air taken in through an intake opening substantially evenly into the house and discharging the air within the house by natural exhaust through an exhaust window. A livestock house for practice of the method is also disclosed.
