Immunomodulatory feed additives might offer alternatives to anti-microbial growth
\npromoters in swine production. The present study was conducted to assess the effects of
\nb-1,3 ⁄ 1,6 glucans, i.e. of specific yeast cell wall components, on immune function and
\ngrowth performance in pigs. After weaning at 4 weeks of age, 75 piglets were allocated to 3
\ndifferent groups for 4 weeks, the diet was supplemented with 0, 0.015 or 0.03% of
\nb-glucan, respectively. All animals were vaccinated against porcine reproductive and
\nrespiratory syndrome (PRRS). After 4 weeks, average daily gains (ADG) of b-glucan
\ntreated pigs were not different from the controls. Feed intake was tendentiously (p < 0.1)\nincreased at 0.03% b-glucan, without alteration of feed efficiency. Serum haptoglobin\nconcentrations at the end of the 4 week treatment were increased in all groups when\ncompared to the initial levels (p < 0.001), without differences between the groups\n(p > 0.05). Haptoglobin levels were inversely related to ADG. Lymphocyte proliferation
\nindices were not different in control and treatment groups. Specific vaccination responses,
\nas quantified by the PRRS antibody titres occurred in all animals, but no relation with
\nb-glucan feeding was observed. Our results indicate marginal benefits of b-glucan
\nsupplements for growth performance and no effect on the immune parameters tested. The
\nobserved trend towards increased feed intake needs further elucidation.<\/p>\n","protected":false},"excerpt":{"rendered":"
