Effects of biotin supplementation in corn-soybean meal diet on some immune indices and growth performance in weaned piglets challenged with porcine circovirus type 2.

The purpose of the study was to determine the optimized biotin levels in corn-soybean meal diet for the growth performance and some immune indices in weaned piglets challenged with porcine circovirus type 2 (PCV2).Fifty-four 28 dayold weaned pigs (Duroc × Landrace × Yorkshire) with negative PCV2 antibody and initial body weight of (6.93 ± 0.721) kg were allocated into 6 treatments with 9 replicates per treatment and 1 pig per replicate.On day 1...
