* SEM = Standard error of means. 1 The lesion score index (LSI) is calculated on a range of 0–200 considering the prevalence and severity of the lesions or tear staining in the are considered, where 0 is absence and 200 is all animals with severe lesions/tear staining. 2 The scores were calculated as the prevalence of piglets showing the presence of the clinical sign. Values in bold evidenced significant association (p < 0.05).
