Twenty four growing cross-bred pigs (15.09 ± 0.32kg) were divided at random into 4 groups (T 1-T 4) containing 6 animals each in a CRD model. A basal diet (Control-T 1) was formulated and subsequently T 2 , T 3 and T 4 diets were formed by supplementing antibiotic, probiotic and herbal residue, respectively. The digestibility of nutrients and growth performance were studied. Digestibility of nutrients were similar across all the treatments except for DM digestibility which was higher (P<0.05)

The feed per kg gain was less (P<0.05) in T3 by 1.18, 1.09 and 1.09 times as compared to T 1 , T 2 and T 4 , respectively. There was an increase (P<0.05) in cost of pork production by (Rs) 11.52, 5.84 and 5.66 per kg for T 1 , T 2 and T 4 , respectively. It was concluded that supplementation of probiotic to pig feeds significantly improved the growth performance and may not show considerable difference in terms of nutrient digestibility.
