Abstract
A 49- day feeding trial was conducted to determine the effects of fibre and Nutrase xyla® enzyme supplementation on the haematological parameters of growing pigs fed low and high fibre diets. Sixteen Landrace X Large white cross breed pigs were used in a 2x2 factorial arrangement with 2 enzyme levels (0 and 100ppm) and two dietary fibre levels (10 and 15%). Four dietary treatments tagged T1, T2, T3 and T4 were formulated to be isocaloric (about 3200kcal/kg ME) and isonitrogenous (20% CP) and to contain 5% crude fibre for treatments T1 and T2 and 10% crude fibre for treatments T3 and T4 respectively. All the haematological parameters determined varied greatly but were not significantly (P >0.05) different among dietary treatments. In conclusion, supplementing fibrous feed with enzyme improves the haematological parameters in growing pigs.
