The effect of backgrounding systems on helminth load and serum haptoglobin profile of weaned Angus calves
Keywords:backgrounding, serum haptoglobin, beef calves, helminth
The backgrounding (BKG) segment in beef cattle production systems is characterized by a huge variation in diet type which could affect average daily gain, finishing performance and carcass traits. Internal parasitism of feedlot cattle has been reported to reduce performance and impair immune function through deprivation of host nutrient, allergic reactions and blood loss. Serum haptoglobin may be used as a marker of stress response in beef calves. This study examined the helminth burden and serum haptoglobin profile of weaned beef calves backgrounded using different feedstuff. We hypothesized that helminth load and serum haptoglobin profiles would differ in calves assigned to different backgrounding systems.
