A method for preparation and use of concentrated serum: experimental study.
Native animal sera are effectively freeze concentrated by slow cooling to -82°C for 18-24 h at a velocity of 0.1-0.5°C/h. The initial serum is concentrated 2-6-fold by this method. Use of concentrated serum reduces the incidence of gastroenteritis during the postnatal period of animal development and improves the survival.
