Effects of gaseous hydrogen sulphide on diarrhoea rate and faecal morphology of weaning pigs

Items	Control group	Treatment group 1	Treatment group 2	Treatment group 3
Diarrhoea rate (%)	5.02	5.55	6.02	6.08
Faecal score	2.07 ± 0.23	2.07 ± 0.18	2.08 ± 0.04	2.11 ± 0.15

Note: The lowercase letters in the same row of data are the same, indicating that the difference is not significant (p > .05); the lowercase letters are different, indicating significant difference (p < .05); the same line of uppercase letters is different, indicating that the difference is extremely significant(p < .01).
