“…Furthermore, probiotics and acidifiers improved the count of Lactobacilli, since the beneficial effect of these additives could be attributed to their effects in suppressing the pathogenic bacteria and improving the growth of beneficial one (Getachew, ; Mirza, Rehman, & Mukhtar, ). In pigs, dietary supplementation of increasing levels of protected organic acids linearly improved the counts of faecal Lactobacillus, while the Salmonella and E. coli counts , faecal ammonia, diarrhoea score and acetic acid emissions were linearly decreased ( p < .05) (Yang, Lee, & Kim, ). Broiler fed rations supplemented with organic acids showed a decrease (linear, p = .002) in E. coli populations and increase ( p = .042) in Lactobacillus populations (Nguyen, Lee, Mohammadigheisar, & Kim, ).…”

“…But, digestibility of protein, crude fibre and ether extract were improved due to organic acid in comparison with control (Ndelekwute et al, ). Yang et al () evaluated the impact of protected organic acids on pig performance, faecal microbial counts and nutrient digestibility, and they found that 0.2% of protected organic acids increased the apparent digestibility of dry matter compared with control ( p < .05). Supplementation of protected organic acid blends to pig diets revealed beneficially affects ileal noxious gas and the nutrient digestibility, (Devi, Lee, & Kim, ).…”

“…Dietary inclusion of 0.2% protected organic acid to pigs has the potential to enhance the growth rate. Feeding protected organic acid rations to piglets improved the average body gain during 0–2 weeks and overall period (0–6 weeks) (Yang et al, ). In broilers, the dietary supplementation with organic acid improved body weight gain and feed efficiency when compared with control.…”

Ever since the European ban on use of in‐feed antibiotics in food animals, the search for alternate antibiotic‐free growth promoter is undertaken worldwide. There are few alternatives such as probiotics, pre‐biotics, phytochemicals, enzymes and organic acids. Among these alternatives, the organic acids or simply acidifiers play an important role in gut health in animals. The acidifiers could be used to favourably manipulate the intestinal microbial populations and improve the immune response, hence perform an activity similar to antibiotics in food animals in countering pathogenic bacteria. Acidifiers also improve the digestibility of nutrients and increase the absorption of minerals. The incorporation of organic acids also leads to thinning of the intestinal lining which facilitates better absorption of nutrients and its efficient utilization. However, their effect will not be similar among all types of organic acids as their mechanism of activity is based on its pKa value. Moreover, there are claims about the neutralization of acids by the secretion of bicarbonates in the initial part of intestine, reactivity with metallic items in feed mills and reduced palatability due its bitter taste demands non‐reactive and targeted delivery for better performance. Currently, coated salts of acidifiers are available commercially for use in food animals especially pigs and poultry. The present review highlights the role of different acidifiers in livestock nutrition with their potent applications in improving nutrient digestibility, mineral utilization, meat quality, enhancing immunity, antimicrobial effects in countering pathogenic bacteria, boosting performance and production, and thus safeguarding health of livestock animals and poultry.

“…The vast majority of commensal micro-bacteria are well adapted to the host environment but also can be shaped by various factors such as nutrient import and external circumstances [2, 3]. Weanling period is a special developmental stage throughout the entire lifecycle of pig, during which piglets have exhibited rapid growth, high demand for nutrition, fast energy harvesting capability [4], and succession of gut microbial composition [5-7]. However, common diseases such as digestive disorders and intestinal inflammation, often plague the piglet farming during this rearing phase.…”

23Nutritional interventions play a critical role in modifying the intestinal microbiome of 24 host animals. This study was conducted to interrogate the physiological effects on 2 25 fecal microflora of weaned piglets via the dietary supplemented with two types of 26 products of Citrus reticulata "Chachi", respectively. For this purpose, A total of 72 27 piglets with uniform sizes were randomly assigned to four dietary treatment groups 28 consisted of a negative control group (NCG), a fermented citrus reticulata "Chachi" 29 pulp group (FCRPG), a Citri Reticulatae Pericarpium group (CRPG) and a positive 30 control group (PCG) in a 21-day feeding trial. After the raising experiment, fresh 31 feces of piglets were analyzed systematically using multi-omics technologies. 32Metagenomics method with high-throughput compositional characterization indicated 33 that the architecture and diversity of fecal microbiome were both influenced by these 34 two additives and compound antibiotics. Metabolite analysis showed that FCRPG 35 have an significant effects on fecal short-chain fatty acids (SCFAs) among four 36 treatment groups. Results of functional proteomics approaches found that FCRPG 37 presented the highest butyrate metabolic level, and CRPG showed the highest flavone 38 and flavonol biosynthesis level in feces. In addition, NCP produced an effective effect 39 on adjusting fecal microbiota profile. Consequently, our findings demonstrate that 40 dietary supplementation with FCRP or CRP modulates the microbial taxa, metabolic 41 and proteomic alterations in fecal microbiota of weaned piglets for health 42 maintaining.43 44 3 48 metabolism, immune regulation and gene expression. The vast majority of commensal 49 micro-bacteria are well adapted to the host environment but also can be shaped by 50 various factors such as nutrient import and external circumstances [2, 3]. Weanling 51 period is a special developmental stage throughout the entire lifecycle of pig, during 52 which piglets have exhibited rapid growth, high demand for nutrition, fast energy 53 harvesting capability [4], and succession of gut microbial composition [5-7]. However, 54 common diseases such as digestive disorders and intestinal inflammation, often 55 plague the piglet farming during this rearing phase. Gut microbiota obviously play the 56 function of facilitating adaption of weanling piglets to fibrous ingredients and 57 reducing the risk of colonization of enteric pathogens after weaning [8]. Actually, 58 although antibiotics have been pervasively applied many decades for antimicrobial 59 application and growth promoting for livetocks in China, European Union has banned 60 their prophylactic use in modern swine industry for the potential public hazard of 61 bacterial resistances and drug residues since 2006 [9, 10]. Thus, nutritional strategies 62 have been employed as an efficient way to improve intestinal microbiota architecture 63 for the purpose of restricting the use of antibiotics and enhancing the health of piglets 64 except for alternative ...

This study determined the potential of formic acid plus monolaurin (FA + ML) as an alternative to antibiotics in diet when piglets are challenged with ETEC. Piglets fed the FA + ML diet had lower fecal score and rectal temperature after the ETEC challenge. In addition, FA + ML supplementation induced lower plasma TNF-α, IL-6, and IL-1β concentration postchallenge, downregulated the mRNA expression of TNF-α, IL-1β, IL-6, and TLR4 in the ileum and TLR4 and CFTR in the jejunum. Phosphorylation levels of NF-κB p65 and MAPK p38 were reduced in the ileum of piglets fed FA + ML diet. Supplementation of FA + ML increased the relative abundance of genera Lactobacillus especially Lactobacillus amylovorus species and decreased the genus abundances of Actinobacillus, unidentified Enterobacteriaceae, Moraxella. Collectively, the combination of formic acid and monolaurin in diets have the potential to be an antibiotic alternative to mitigate inflammatory response in piglets challenged with ETEC.
