ABSTRACT The objective of the present study was to evaluate the effects of blends of dietary protected organic acid supplementation on growth performance, nutrient digestibility, blood profiles, faecal microflora, and gas emission on sows and piglets with emphasis on their modes of action to improve pig performance. A total of 12 sows with an average initial body weight (BW) of 252.40±11.7 kg were used in this trial. Growth performance, blood profiles, and nutrient digestibility of sows and piglets fed protected organic acid were evaluated. The dietary treatments included a basal diet (CON); CON + 0.1% protected organic acid; and CON + 0.2% protected organic acid. The BW and back fat of sows was checked four days prior to farrowing and at the weaning day to calculate BW loss and back fat loss during that period. Inclusion of 0.2% protected organic acid provided a greater digestibility than CON diets throughout the experimental period in lactating sows. Dietary supplementation with 0.2% protected organic acid led to a higher white blood cell and lymphocyte concentration than CON treatment in sucking piglets. Immunoglobulin G concentration observed was greater in protected organic acid groups in lactating sow and sucking piglets. Increased faecal Lactobacillus counts with decreased E. coli concentrations were observed with the diets of protected organic acid fed to lactating sows. The E. coli counts were decreased in weaning piglets. The faecal H2S contents were decreased in 0.2% protected organic acid diets during farrowing on day 1. Dietary supplementation with protected organic acid blends beneficially affects the nutrient digestibility, ileal noxious gas (NH3 and H2S) emission, as well as intestinal microbial balance in lactating sows.
