FIELD: veterinary science.
SUBSTANCE: invention relates to virology. The invention can be used at industrial hog farms. The vaccine contains a mix of inactivated porcine transmissible gastroenteritis and epidemic diarrhea viruses and adjuvant. Viruses are obtained from the small bowel of artificially infected colostrum-free pigs where such viruses accumulate in a titer of 6.7-7.5 lg ID50/ml and show an antigenic activity of at least 1:8 in EIA. Virus suspensions are mixed at a 1:1 ratio by volume with 20% of aluminium hydrate added to the mix as adjuvant.
EFFECT: vaccine PTGE/PED is harmless and non-reactogenic and has a pronounced protective effect.
