We aimed to investigate the effects of Clostridium butyricum-, Bacillus subtilis-, and Bacillus licheniformis-based potential probiotics on the growth performance, intestinal morphology, immune responses, and caecal short chain fatty acids (SCFAs) and microbial structure in broiler chickens. Three treatment groups containing a total of 1200 one-day-old AA broilers were included: birds fed with a basal diet only (Con), birds fed with added 1010 probiotics cfu/kg (ProL), and birds fed with added 1011 probiotics cfu/kg (ProH). The dietary probiotics significantly improved the final and average body weights and serum immunoglobulins A, M, and Y. The probiotics also enhanced the ileal morphology and improved the caecal acetate, butyrate, and propionate contents. Furthermore, 16S rRNA sequencing revealed that dietary compound probiotics modulated the caecal microflora composition as follows: (1) all birds shared 2794 observed taxonomic units; (2) treatment groups were well separated in the PCA and PCoA analysis; (3) the relative abundance of Parabacteroides, Ruminococcaceae_UCG-014, Barnesiella, Odoribacter, [Eubacterium_coprostanoligenes_group], [Ruminococcus]_torques_group, and Butyricimonas significantly varied between treatments. The compound probiotics improved the growth performance, serum immune responses, the ratio of ileal villus height to crypt depth, and major caecal SCFAs in broiler chickens. The dietary C. butyricum-, B. subtilis-, and B. licheniformis-based probiotics improved overall broiler health and would benefit the poultry industry.

The control of the immune system of pigs after weaning is important in pig farming because productivity depends on the survival of the post-weaned pigs. Previously, antibiotics would have been administered in the case of infectious diseases to increase the survival rate of post-weaned pigs, but now, the use of antibiotics is strictly restricted in order to prevent other problems such as the occurrence of antibiotic-resistant pathogens. In this study, the effect of fermented kefir as a functional feed additive as a replacement to antibiotics was evaluated in terms of the microbial profile in fecal samples, immunological factors in the blood of pigs, growth performance measured as average daily gain (ADG) and the feed conversion rate (FCR) of post-weaned pigs. In the kefir-treated group, the number of lactic acid bacteria and Bacillus spp. in the fecal samples of the pigs increased with the kefir treatments. Interestingly, the number of coliform groups as opportunistic pathogens was reduced in the fecal samples of pigs treated with kefir. We found out that treatment with kefir enhanced the innate immunity of post-weaned pigs though the reduction of IL-6 as a proinflammatory cytokine and an increase in IgG as an immunoglobulin, enhancing immunological defense against pathogens. Finally, after treatment with kefir, we observed that the ADG of post-weaned pigs increased to 135.6% but FCR decreased to 92.2%. Therefore, this study shows that fermented kefir can be used as a functional feed additive and an antibiotic alternative in order to improve both the innate immune system and growth performance of post-weaned pigs.

The present study evaluated the use of the indigenous probiotic Lactobacillus plantarum and commercial probiotic containing Bacillus spp. in the culture of L. vannamei in a biofloc system. Shrimp were fed with four diets: L. plantarum, Bacillus spp., L. plantarum + Bacillus spp. and feed with no additives. Growth performance, water quality variables and microbiological counting of water and digestive tract of shrimp were determined. The control group and L. plantarum treatment showed better growth performance. The highest feed conversion ratio (FCR) and the lowest survival were obtained in the L. plantarum + Bacillus spp. treatment, which had significantly higher nitrite values. Vibrio spp. counts in the water were lower in the L. plantarum and L. plantarum + Bacillus spp. treatments and were lower in the intestinal tract in the L. plantarum treatment. Lactic acid bacteria (LAB) was higher in the L. plantarum treatment in the water and digestive tract. The count of total heterotrophic bacteria (THB) deferred only among Bacillus spp. and L. plantarum + Bacillus spp. treatment, being higher in the latter group. In Bacillus spp. treatment, no presence of LAB was detected in the water or intestinal tract. We conclude that the use of L. plantarum combined with Bacillus spp. negatively affected survival, FCR and water quality, but that the use of L. plantarum alone reduced the presence of Vibrio spp., even though it did not change the growth performance of L. vannamei.
