The problem of enriching feed diets with high-quality protein could be effectively solved by using dried blood meal, in particular dried pig blood. Current research is aimed at studying high-protein meals from dried pig blood in piglets’ diets as a source for their better and intense growth. Fresh stabilized or defibrinated blood and its fractions were used for drying, which have to be processed as soon as after being collected, but no later than two hours after collection with the stored temperature below 15°C. A spray (blood and blood products) operating unit with the air compressor and straight jet spray nozzles was used to prepare the dried blood. Spray-drying resulted in production of dried blood meal, which is highly soluble and efficient for various purposes. For the research, a feedstuff diet with dried blood meal was developed. Eight groups of 28-day-old piglets of different genotypes, each containing 30 animals, were formed using the balanced group method. The piglets in the experimental groups were fed usual diet and 200 g of dried pig blood. It was noted that dried blood in the diet of piglets positively affected physiological condition of the animals and their growth rate.
