Table 3 Posterior means of genetic parameters (limits of HPD90) for intercept (int) and slope coefficients of body weight at five measurement events (ME) when ticks (TICK), gastrointestinal nematodes (GIN), and Eimeria spp. (EIM) burdena were used as independent variables in single-trait linear random regression models
