This study investigated the effects of coriander seed powder and Lactobacillus acidophilus solution (LAS)
on the growth, nutrient digestibility, blood parameters, and intestinal health of growing rabbits under subtropical
conditions. Forty Californian rabbits, aged 35 days with an average body weight of 588 ± 34 g, were randomly
assigned to four groups: a control group fed a standard diet, a group (T1) receiving the basal diet supplemented with
1.5% coriander seed powder, a group (T2) receiving the basal diet with oral LAS at 1 × 109 CFU/kg, and a group
(T3) receiving both coriander seed powder and LAS. The study measured body weight, daily weight gain, feed
conversion ratio, mortality rate, blood metabolites, nutrient digestibility, and intestinal histomorphology. Results
showed that rabbits fed with 1.5% coriander seed powder had significant improvements in body weight gain, feed
conversion, and a reduction in mortality compared to the control. Both coriander seed powder and LAS improved
blood metabolites, nutrient digestibility, and intestinal health. However, the combination of both additives did not
provide additional benefits over the individual treatments. The findings suggest that either 1.5% coriander seed
powder or LAS can enhance growth performance and health in rabbits under subtropical conditions.
