“…This reason could be explained for the current Advances in Animal and Veterinary Sciences study, which indicates that the dietary supplementation with a combination of PROB and ORAC had positive synergism effects on growth performance and FCR than the supplementation with PROB or ORAC alone. These results were confirmed by (Lei et al, 2018).…”

“…Eubiotics are referred as a healthy balance of microflora in the gastrointestinal tract (Nowak et al, 2017). Several types of eubiotics, such as organic acids, essential oil compounds, and probiotics, have been shown to have a positive effect on gut health and overall animal performance (Agboola et al, 2015;Zhang et al, 2016;Lei et al, 2018). However, the extent of the positive effects is variable depending on the products used.…”

This study was carried out to evaluate the effects of dietary supplementation of probiotics (PROB), organic acids (ORAC), and their mix (PROR) on growth performance, nutrient digestibility, and fecal noxious gas concentration in grower-finisher pigs. Twenty-four barrows [(Pietrain × Duroc) × (Landrace × Yorkshire)], with an average initial body weight of 26 ± 0.77 kg (around 75 days old), were equally divided into four dietary groups, 6 replicates each group. The animals were housed individually in metabolism cages. The four experimental diets consisted of a basal diet (CONT), PROB diet (CONT + 0.2% PROB), ORAC diet (CONT + 0.2% ORAC), and PROR diet (CONT + 0.2% PROB + 0.2% ORAC) for 60 days including 2 periods (25-45 kg and 45-65 kg). In comparison to the CONT group, dietary supplementation of PROB or ORAC or PROR increased ADG and decreased FCR (P < 0.0001), with the higher ADG and lower FCR for PROR group during the entire experimental period. Pigs fed PROB or ORAC or PROR diets led to higher (P < 0.05) apparent total tract digestibility of protein, organic matter, neutral detergent fiber, and phosphorus than those fed CONT diet. A significant decrease in ammonia (NH 3 ) and hydrogen sulfide (H 2 S) concentrations were observed in diets with PROB or ORAC or PROR, with lower values for PROR diet. In conclusion, in grower-finisher pigs, dietary supplementation of either PROB or ORAC as a single product or their combination had improvements in performance parameters, nutrient digestibility, and fecal NH 3 and H 2 S emissions compared with CONT diet. There were no differences in performance parameters between the use of the single product and the combination. In general, a diet containing a combination of PROB and ORAC had larger effects on parameters observed than a diet containing either PROB or ORAC.

“…Lei et al also investigated how a blend of matrixcoated organic acids and MCFAs, without or with a probiotic (Enterococcus faecium), affected the growth performance of finishing pigs [83]. The feed supplement mixture contained 17% fumaric acid, 13% citric acid, 10% malic acid, 0.6% capric acid, and 0.6% caprylic acid, and the mixture was incorporated at 0.05% or 0.1% of the diet (equivalent to~0.005-0.01% total MCFAs), without or with 0.002% probiotic.…”

Ongoing challenges in the swine industry, such as reduced access to antibiotics and virus outbreaks (e.g., porcine epidemic diarrhea virus, African swine fever virus), have prompted calls for innovative feed additives to support pig production. Medium-chain fatty acids (MCFAs) and monoglycerides have emerged as a potential option due to key molecular features and versatile functions, including inhibitory activity against viral and bacterial pathogens. In this review, we summarize recent studies examining the potential of MCFAs and monoglycerides as feed additives to improve pig gut health and to mitigate feed pathogens. The molecular properties and biological functions of MCFAs and monoglycerides are first introduced along with an overview of intervention needs at different stages of pig production. The latest progress in testing MCFAs and monoglycerides as feed additives in pig diets is then presented, and their effects on a wide range of production issues, such as growth performance, pathogenic infections, and gut health, are covered. The utilization of MCFAs and monoglycerides together with other feed additives such as organic acids and probiotics is also described, along with advances in molecular encapsulation and delivery strategies. Finally, we discuss how MCFAs and monoglycerides demonstrate potential for feed pathogen mitigation to curb disease transmission. Looking forward, we envision that MCFAs and monoglycerides may become an important class of feed additives in pig production for gut health improvement and feed pathogen mitigation.

“…The diarrhea incidence in weanling pigs challenged with E. coli was reduced by supplementation with an OA-MCFA (C8:0, C10:0) blend [ 90 ]. When the OA-MCFA blend is added with Enterococcus, dry matter improvement had been found in finishing pigs [ 91 ]. Casellas et al instead found that minimal supplementation of MCT long chain triglyceride (LCT) could improve the survival of the smallest piglets [ 92 ].…”

Reduction of antibiotic use has been a hot topic of research over the past decades. The European ban on growth-promoter use has increased the use of feed additivities that can enhance animal growth performance and health status, particularly during critical and stressful phases of life. Pig farming is characterized by several stressful periods, such as the weaning phase, and studies have suggested that the proper use of feed additives during stress could prevent disease and enhance performance through modulation of the gastrointestinal tract mucosa and microbiome. The types of feed additive include acids, minerals, prebiotics, probiotics, yeast, nucleotides, and phytoproducts. This review focuses on commonly used acids, classified as inorganic, organic, and fatty acids, and their beneficial and potential effects, which are widely reported in the bibliography. Acids have long been used as feed acidifiers and preservatives, and were more recently introduced into feed formulated for young pigs with the goal of stabilizing the stomach pH to offset their reduced digestive capacity. In addition, some organic acids represent intermediary products of the tricarboxylic acid cycle (TCA), and thus could be considered an energy source. Moreover, antimicrobial properties have been exploited to modulate microbiota populations and reduce pathogenic bacteria. Given these potential benefits, organic acids are no longer seen as simple acidifiers, but rather as growth promoters and potential antibiotic substitutes owing to their beneficial action on the gastrointestinal tract (GIT).
