Relationship between resistance to a Pasteurella Multocida experimental infection and production traits in rabbits

Abstract

Nine hundred and fifty five rabbits were inoculated at 6 weeks of age with a pyogenic strain of Pasteurella multocida and were scored for resistance from 0 to 4 by taking into account postmortem examinations. Fifty five sires having at least 10 inoculated offspring produced also 9943 rabbits tested for health and growth and 1468 females tested for reproduction in commercial farm conditions. Total number born and number born alive per litter were significantly lower in daughters of resistant sires (-0.27 and-0.41). Prevalence of digestive diseases and infectious diseases were significantly lower in the resistant growing rabbits than in the susceptible ones (-1.7 point and-3.0 points, respectively). This result suggests that resistance to pasteurellosis assessed by an experimental infection is favorably correlated to resistance to other infectious diseases.
