Comparative evaluation of growth performance, serum biochemical profile and immunological response of the Nigerian indigenous and large white x landrace crossbred pigs

Abstract

This study was conducted to compare growth performance, immunological response, and biochemical profile between local or Nigerian indigenous pigs (NIP) and exotic Large White x Landrace crossbred pigs (LWL). Twenty weanling pigs, aged six weeks were divided into groups A (NIP) and B (LWL); each group was randomly assigned into two replicates of five pigs. Feed and animal management were similar and study lasted ten weeks. Their feed and water intake, average daily weight gain (ADG), and gain: feed or feed efficiency were determined. All the pigs were vaccinated with1 ml of 10 % sheep RBC per pig at week 4 and boosted at week 7. Their antibody titres and serum biochemical profiles were determined using standard procedures. Daily feed and water intake and weight gain were significantly (p < 0.05) higher in LWL than NIP. There was no significant (p > 0.05) difference in their gain: feed but figures were higher in NIP. Although LWL had higher antibody titres at weeks 1 of initial and revaccination, NIP recorded higher titres at weeks 2, 3 and 4 of initial and 2 of revaccination, respectively. Albumin levels in both groups showed a significant (p = 0.003, t = 8) difference in their mean on week 1 following initial vaccination, their values being 4.29 ± 0.05 and 4.67 ± 0.08 g/dL for groups A and B, respectively.The NIP showed significantly (p < 0.05) higher total protein and globulin throughout the period of assay. Although the LWL grew faster and had better immediate immunological performance, the NIP recorded slightly higher feed efficiency and more sustained antibody titres post vaccination with Sheep RBC.
