Feed intake, growth digestibility of dry matter and nitrogen in young pigs as affected by dietary cation-anion difference and supplementation of xylanase

An experiment was conducted to test the effect of dietary cation-anion difference (CAD,Na++K+-Cl-, mEq/kg diet) and xylanase addition on feed consumption, digestibility of nutrients, plasma electrolyte balance and growth performance in young pigs. A 2x3 factorial arrangement with three dietary CAD levels (-100,200 and 500 mEq/kg) and two levels of xylanase supplementation (0 and 0.1% xylanase derived from Trichoderma longibrachiatum) was used. Thirty six individually housed, castrated pigs (5weeks old) with an initial body weight of 9.340.28 kg (mean 0.28 kg (mean SEM) were randomly assigned to the six treatments. Diets were provided to pigs as cold pellets. Pigs had an ad libertum access to feed and water. Venous plasma Cl- concentration was higher (p<0.0001) in dietary CAD of - 100 mEq/kg group compared with the other two CAD groups. Dietary CAD did not affect Na+ and K+ concentration in the venus plasma. Growth rates were higher (p<0.05) in pigs receiving dietary CAD of 200 mEq/kg (657 g/pig, day) and dietary CAD of 500 mEq/kg (603 g/pig. Day) than in pigs receiving dietary CAD of -100 mEq/kg(484 g/pig. Day). Fecal dry matter and nitrogen decreased with increasing dietary CAD. Fecal apparent digestibility of dry matter and nitrogen was higher (p<0.05) in the dietary CAD of 500 mEq/kg compared to the two lower level CAD groups. Supplementation of xylanase did not affect the performance of pigs. Xylanase addition in the diet significantly increased apparent fecal digestibility of dry matter and tended to increase apparent digestibility of nitrogen. No interaction between dietary CAD and xylanase was found. In conclusion dietary CAD influenced the performance and digestibility of nutrients of pigs. Xylanase supplementation improved digestibility of dry matter
