Effect of a bacterial xylanase and/or antibiotic growth promoter on zootechnical performances of piglets fed arabinoxylan rich diets.

ABSTRACT

272 cross bred piglets (Saw (wbp x pbz) x Boar (Hamp x Pietr) were fed a basal diet rich in arabinoxylans from 29 days old to 84 days old. In the prestarter period (29 to 42 d) the basal diet was formulated with 27% wheat, 10% barley, 10% maize, 18% soybean meal and 22% milk products and the analytical content was adjusted at 13.81 MJ/kg metabolisable energy, 19.6% crude protein, 12.4% lactose, 1.38% lysine and 0.88% SAA. During the starter period (43 to 84 d) the basal diet was formulated with 53% wheat, 25% barley and 16% soybean meal and the analytical content was adjusted at 12.91 MJ/kg metabolisable energy, 16.7% crude protein, 1.09% lysine, 0.62% SAA.
