The study was conducted to investigate the effect of dietary supplementation of herbal mixture on growth performance and health status of Large White Yorkshire weaned piglets during the post-weaning period (from 28 to 70 days of age) reared under farm conditions of Mizoram. A total number of 144 (18 litters) Large White Yorkshire young pigs weaned at 28 days old were taken for the study period of 42 days (Day 28-70) and were randomly divided into three groups viz., Control (C) fed basal diet, Treatment-1 (T₁) fed basal diet incorporated with 0.6% herbal mixture and Treatment-2 (T₂) fed basal diet incorporated with 1.2% herbal mixture in such a way that there were 6 replicates in each group with 1 litter as one replicate. Findings of the study revealed significantly (p<0.05) higher average body weight on day 42, 49, 56, 63 and 70 as well as significantly (p<0.05) improved average daily gain on 5^th, 6^th, 7^th, 8^th and 9^th week of age as well as on the overall average daily gain. Feed conversion efficiency on 5^th and 6^th week of age (first two weeks of post weaning period) and the overall FCE in weaned piglets reared under Treatment-1 and Treatment-2 were found to be significantly (p<0.05) better as compared to weaned piglets under control group. A significant (p<0.05) decrease in the occurrence rate (%) of diarrhoea, general appearance and faecal consistency were observed in weaned piglets under treatment groups when compared to control group. The study demonstrated that dietary supplementation of herbal mixture (0.6% and 1.2%) significantly improved growth performance and reduced the occurrence rate (%) of diarrhoea in Large White Yorkshire weaned piglets during the post-weaning period (day 28-70).
