The aim of the study was to assess the production results and health status of sows and their offspring modulated by supplementation of selected amounts of (1,3)-(1,6)-β-D-glucan. It was added in doses of 0, 100, 200, or 300 ppm to the feed mixtures for sows from day 80 of gestation and for their offspring from day 10 to 45 of life. Production results were estimated based on: daily gains, average feed intake and conversion ratio, and mortality. Blood, colostrum and milk samples were collected to estimate immunological stimulation based on the levels of total protein and its fractions, and on haptoglobin. Twelve representative pigs (aged 45 days) were slaughtered and the small intestine was dissected. The obtained data suggest that the best effect on health status and production results was obtained when doses of 200 and 300 ppm of β-glucans were used.
