a-bValues within a row lacking a common superscript letter are different (P < 0.05).
1Data are least square means of 10 observations for all treatments.
2β-Mannanase = Natupulse® TS; BASF SE, Ludwigshafen, Germany. The β-mannanase unit TMU is defined as the amount of enzyme that produces reducing carbohydrates having a reducing power corresponding to one µmol mannose from locust bean gum (0.3 g/100 ml buffer solution) in one minute under the assay conditions of 50.0 +/-0.1 °C and pH 3.5.
3ADG = average daily gain; ADFI = average daily feed intake; G:F = gain-to-feed ratio.
