Table 4 Odds ratio estimates, lower and upper confidence interval of ranking AMB, TDR and BCS trait most in Nguni breeding bulls

From: Preferential traits for breeding Nguni cattle in low-input in-situ conservation production systems

Predictors Aggression and mating behaviour (AMB) – Rank 1 Tick and disease resistance (TDR) – Rank 2 Body condition score (BCS) – Rank 3

  1. NB: Higher odds ratio estimates indicate greater difference in preference between levels of predictors.
  2. CI Confidence Interval (set at 95%).
