Abstract
Introduction: Monogastric animals such as pigs and poultry cannot handle cellulose, hemicellulose, and lignin, which form the major components of agro-industrial products. This feeding trial was carried out to evaluate the responses of growing boar-fed sundried cassava peel meal (CPM)-based diet supplemented with the enzyme.
Materials and methods: Thirty-two growing boars (Large white x Landrace), eleven weeks old with an average weight of 25.00 ± 0.30 kg, were allocated randomly to dietary treatments. A basal diet was compounded containing 48% sundried CPM. The dietary treatments were T1 (control) supplemented with 0.0g/100g, and other treatments, including T2, T3, and T4, received 0.5g/100kg, 1.5g/100g, and 2.0g/100g levels of Quadraxyme® supplementation, respectively. Quadraxyme® is a product of Quadragen Veterinary Health Private Limited. Quadraxyme® contains amylase, cellulase, xylanase, pectinase, lipase, arabinose, α-galactosidase, and β -glucosidase.
Results: This study showed significant differences in average feed intakes and daily weight gains across the dietary treatments. Pigs in the T4 group had the highest weight gain, followed by those in T2 and T3 groups, while the minor weight gain was in the diet with no enzyme supplementation. The dietary treatments significantly influenced hematological parameters in almost all the studied indices. The mean corpuscular hemoglobin concentration (MCHC) values of pigs fed the T1 diet recorded significantly higher MCHC and a reduction in concentrations of packed cell volume (PCV), red blood cell (RBC) counts, and a slight increase in mean corpuscular volume (MCV) concentration. The dietary treatments did not affect the total blood protein and albumin levels of the growing pigs enrolled in this investigation. The result showed that the levels of enzyme supplementation to the SDCPM-based diet did not significantly influence the electrolytes of the growing boars. The PO42- increased in enzyme-supplemented diets, and group T4 supplemented with 0.20g/100kg of the enzyme recorded the highest PO42- value (6.79mg/100ml) among the other groups.
Conclusion: It is concluded that including 0.20g/100kg in a 48% sundried CPM-based diet for growing pigs enhanced growth and feed conversion, improved phosphorus utilization, and had no adverse effects on growth and blood parameters.
