NUTRIENT DIGESTABILITY, HAEMATOLOGICAL AND SERUM BIOCHEMICAL PROFILES OF GROWER PIGS FEED SUNDRIED BREWER’S DRIED GRAIN SUPPLEMENTED WITH QUADRAXYME®

Abstract

The study investigated the apparent nutrient digestibility, haematological, and serum biochemical indices of pigs fed graded levels of sundried brewer’s dried grain supplemented with quadraxyme. Eighteen (18) local breeds of grower pigs with an average weight of 12.00kg were sourced within the Wukari metropolis. The pigs were divided into three groups of six animals per group replicated three times in a completely randomized design. The animals were fed ad libitum and the experiment lasted for 56 days. Diet 1 served as a control containing 100% maize bran, Diet 2 contained 50% maize bran and 50% SDBG, and Diet 3 contained 100% SDBDG inclusion levels respectively. The diets were supplemented with 0.2kg /100kg of Quadraxyme. Data collected during the study were subjected to Analysis of Variance using JMP SAS (2014) version13. Significant level of difference among treatment means were separated using the same statistical tool. Result from the digestibility trial shows that all parameters are significant, haematological and biochemical analysis showed all parameters were not significantly(0.05) different. The treatment with supplementation of sundried brewer’s dried grain with enzyme improved the crude fibre, dry matter, crude protein and ether extract digestibility of the pigs when compared to those fed maize diet. Sundried brewer’s dried grain improved the WBC, MCH, RBC, Haemoglobin, Haematocrit, MCHC, urea, albumin, globulin and creatinine levels but did not affect the MCV, cholesterol and glucose levels of pigs. Compared to pigs fed maize diet, the sundried brewer's dried grain supplemented with enzymes improved the pigs' crude fibre, dry matter, crude protein, and ether extract digestibility. It also improved the pigs' WBC, MCH, RBC, Haemoglobin, Haematocrit, MCHC, urea, albumin, globulin, and creatinine level. It was concluded that T2(50%) sun dried brewers dried grains supplemented with enzyme had the best array of nutrient digestibility, haematological and serum biochemical values. This study recommends the use of 50% sun dried brewers grain supplemented with enzyme in pig diets because of superior nutrient digestibility, haematological, and serum biochemical parameters.
