The adhesion of each probiotic and its colonization in the intestine is species-specific, and this may be key to produce a positive outcome. The present study was conducted to establish the superiority of Pediococcus acidilactici strain FT28 (swine origin probiotic) over Lactobacillus acidophilus NCDC-15 (dairy origin probiotic) in terms of their efficacy in improving blood biochemical profile, carcass and physicochemical properties of meat in fattening pigs. A total of 36 piglets (28 day) were randomly distributed to three groups of four replicates of three animals in each. Groups were fed one of three experimental diets as basal diet alone (Control-T0); basal diet supplemented with Pediococcus acidilactici strain FT28 (T1) and basal diet supplemented with Lactobacillus acidophilus NCDC-15 (T2).
The total protein and albumin levels in serum increased, and the triglyceride decreased with probiotic supplementation either of swine or dairy origin, compared to control. The globulin and glucose levels were higher in T1 group across the dietary groups. The carcass traits were unaffected except for the weight of ham, kidney and spleen which were higher in the T1 group. The water holding capacity and TBARS were improved in the T1 compared to control, but comparable to the T2 group. The ether extract, pH and sensory attributes (juiciness and appearance) were improved in the T1 compared to other dietary treatments.
In conclusion, the present study proved that the supplementing host origin probiotic (Pediococcus acidilactici strain FT28) could be a newer strategy to improve the carcass yield, lean meat and its keeping quality without any adverse effect on blood biochemical profile. However, further research is required to ascertain the findings observed in the present study.
