        A total of 240 weaned pigs (Landrace ×Yorkshire × Duroc, 22±3 d of age, 5.16±0.90 kg initial body weight) were used to study the effect of feeding level of microbial fermented soya protein on their blood hematology, enzymes and immune cell populations. The microbial (Aspergillus oryzae + Bacillus subtilis) fermented soya protein (FSP) was used. Pigs were allotted to four dietary treatments, each comprising of 4 pens with 15 pigs. Basal diets consisted of 15% soya bean meal (Control diet); while for treatment diets SBM was replaced with 3, 6 and 9% FSP. The experimental diets were fed from 0 to 14 day after weaning and then a common commercial diet was fed from 15 to 35 day. Blood was collected on 14 and 35 day of experiment and analyzed for hematology, plasma aspartate transaminase (AST), plasma alanine transaminase (ALT) and immune cell populations. Increasing the level of FSP in the diet of pigs linearly decreased distribution of red blood cells (P<0.01), MPV (P<0.05), MO (P<0.05), EO (P<0.05) and BA (P<0.05) on d 14. Linear and quadratic decrease in the RBC (P<0.05), Hb (P<0.05), HCT (P<0.01), PLT (P<0.001) and EO (P<0.05) and linear increase in the MCHC (P<0.001), MPV (P<0.05), WBC (P<0.05) and NE (P<0.05) on d 35 was noted. Pigs fed with 6% FSP had lower (P<0.05) levels of AST and ALT on d 14, while the levels of ALT and AST on d 35 did not differ among the dietary treatments. Thus the results suggest that microbial fermented soya protein affected the hematological indices, immune cell populations and plasma enzymes in weaned pigs.
