Item	Control	Control + 800 TMU/kg β-Mannanase3	Control + 100,000 TMU/kg β-Mannanase	SEM	P-value
Liver, g	895	865	875	35	0.794
Kidney, g	148	150	143	6	0.445
Spleen, g	58	54	54	3	0.658
Heart, g	153	155	147	6	0.297
Stomach, g	705	673	683	41	0.869
Small intestine, g	1,725	1,650	1,695	53	0.555

¹Data are least squares means for each dependent variable represent 10 observations for the control treatment and 20 observations for the control + 800 TMU/kg and control + 100,000 TMU/kg treatments.

²All organs were inspected for pathological changes, but no abnormalities were detected.

³β-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.
