Effect of Bacillus altitudinis WIT588 spore supplementation to 1st stage and/or 2nd stage weaner diets and antibiotic (AB) + ZnO supplementation to 1st stage weaner diets on faecal scores¹.

	Treatment					SEM	P-value
Treatment day 0–28 PW	Con	Con	Pro	Pro	AB + ZnO

PW, post-weaning; Con, control; Pro, probiotic; AB + ZnO, antibiotic + zinc oxide.

¹Least square means and pooled standard errors of the mean (SEM). Faecal scores were performed visually every day between weaning and day 28 PW and the mean was used for the analysis. The scoring system was as follows; 0 = normal dry, pelleted faeces; 1 = soft faeces with shape; 2 = very soft faeces with liquid (mild diarrhoea); and 3 = watery or bloody faeces (severe diarrhoea).

Data were analysed as repeated measures using the mixed model procedure in SAS with the pig being the experimental unit. Differences in least square means were explored using the t-test after Tukey adjustment for multiple comparisons.
