Online Published on 24 May, 2024. Abstract The current study evaluated the dietary supplementation of encapsulated Lactobacillus plantarum NCIM 2374 (eLpl 2374) and Pediococcus acidilactici NCIM 5721 (ePed 5721) on growth performance and histomorphometric measurements. The survival rate of eLpl 2374 and ePed 5721 after encapsulation did not differ significantly. The in vitro survival rate and efficiency of eLpl 2374 was significantly (P<0.00) better than ePed 5721 in SGJ and SIJ, but was reduced in both the probiotics. Eighteen weaned (6 wk old) male, crossbred Large White Yorkshire (LWY) piglets with mean body weight of 8.77±0.37 kg were randomly distributed in three groups with three replicates with two animals in each replicate. All the animals were fed with basal diet, formulated to meet ICAR (2013) nutrient requirements. The water sprinkled maize powder was allowed for overnight and encapsulated probiotic ePed 5721 (1 ×1011 CFU/mL) and eLpl 2374 (1 ×1011 CFU/mL) was mixed with 100 g of maize powder separately and given to respective groups and control (Contr) group received 100 g of water sprinkled maize powder only. The pigs in eLpl 2374 showed significantly (P<0.00) higher body weight and body weight gain, with reduced feed intake (P<0.01) and improved feed gain ratio (P<0.01) compared to control animals from weaning to grower stage (wk 22), but similar values were recorded from weaning to finisher stage (wk 33). Moreover, pigs in ePed 5721 and control groups showed similar results. Similarly, villus height, crypt depth of duodenum and ileum and goblet cells number were significantly (P<0.01) increased in eLpl 2374 pigs. It may be concluded that supplementation of eLpl 2374 proved to be better choice for improving body weight with better feed gain ratio in pigs upto grower stage.
