General linear mixed model exploring the effect of diet (HF vs HS) and supplementation (SF vs CONT) on two traits referring to helminth infection (fecal egg count and L3 motility) over the 21 day experimental period.

We report the fixed effects but the model also included the horse ID and the horse ID * experimental period as random effects. FEC were assessed four times during the experimental period therefore the model also included time as a repeated measurement. L3 motility was only measured at day 21 and modelled using a multinomial distribution. We report the degrees of freedom (df), F and p values.
