Nowadays, there is an increased public awareness about the risk of developing cross-resistance of pathogens to antibiotics.1 Organic acids, such as propionic acid, have been used for more than 30years to reduce bacterial growth and mould in feedstuffs and thus preserve hygienic quality. Health and performance promoting effects have been demonstrated for a number of organic acids, including formic, fumaric, citric and lactic acid and their salts. In animal rearing, higher feed conversion rates and daily gain as well as reduced incidence of diarrhea, enhance economic return by lower feed costs and shorter time to market may achieved by organic acid supplementation.2
Organic acid definition
The term “organic acid” refers to a broad class of compounds used in fundamental metabolic processes of the body. Chemically, organic acids share the common features of water solubility, acidity, and ninhydrin-negativity (no primary or secondary amines). The term is generally considered to include all carboxylic acids, with or without keto, hydroxyl, or other non-amino functional groups, but does not include most amino acids. Some nitrogen-containing compounds are included, such as pyroglutamate, or amino conjugates like hippurate (benzoylglycine). Short chain fatty acids are also contained in this group (Figure 1).
They are either" Simple monocarboxylic acids such as formic, acetic, propionic and butyric acids or " Carboxylic acids with hydroxyl group such as lactic, malic, tartaric and citric acids or " Short chain carboxylic acids containing double bonds like fumaric and sorbic acids.3 As a group of chemicals, organic acids are considered to be any organic carboxylic acid of the general structure R-COOH (including fatty acids and amino acids). Not all of these acids have effects on gut microflora. Organic acids with specific antimicrobial activity are short-chain acids (C1–C7) and they are widely distributed in nature as normal constituents of plants or animal tissues.4 They are also formed through microbial fermentation of carbohydrates mainly in the large intestine. They are sometimes found as their sodium, potassium or calcium salts. Most organic acids with antimicrobial activity have a pKa‒(the pH at which the acid is half dissociated)-between 3 and 5. Table 1 shows the common name, chemical name, formula and first pKa of organic acids that are commonly used as dietary acidifiers in monogastric animals.
Considerations before selecting organic acid for poultry nutrition
Before any diet manipulation, we should consider the gastro-intestinal characteristics and microbial ecosystems of poultry. Figure 2 show the pH, resident time of feed and microbial population in gastrointestinal tract of chicken. Organic acids and their salts exert growth inhibiting effects on stomach and gut microbes through pH reduction and anion and proton effects in the microbial cell. Growth rates of many microbes like Cl. Perfringens, E. coli or Salmonella ssp. are reduced below pH 5, while acid tolerant microbes are unharmed. Optimum pH for Escherichia coli, Lactobacillus spp., Salmonella spp. Camplylobacter jejuni growth are 6-8, 5.4-6.4, 6.8-7.2, and 6.8-7.2, respectively. Acids used as feed additives have pK values between 3 and 5, and are categorized as being of intermediate strength.2
Acidifiers are used in three ways in a poultry operation:
Injected into the water to kill bacteria, facilitate chlorine in killing bacteria and lowering the pH in the birds' crops. The effect on gram-negative bacteria is increased if the organic acid is not dissociated (Figure 3). Because of this mode of action acidifier need to contain organic acids which are undissociated at different pH-values, so that the anti microbial action is prolonged over a wider pH range.5,6
As the energy content of organic acids is made completely available during metabolism, it should be considered in the energy calculation of feed rations (Figure 4). For example, propionic acid contains up to five times more energy than wheat.7 The effects of organic acids in the reduction of pH and their antimicrobial activity vary considerably depending on their dissociation status. The amount of dissociation depends on the pH value of the environment, which is described by the specific pK (dissociation constant) value for each acid. The lower the pK value, the stronger the acid, which relates to its ability to lower the pH of the environment.
Factors influencing the efficiency of dietary organic acid supplementation
Buffering capacity of dietary ingredients
Buffering capacity is a measure of the amount of acid (0.1 M HCL) required to reach a given pH (usually 3 to 5) of a 10-g slurried sample of the ingredient.8 The ingredients that contribute most to the buffering capacity are proteins and minerals. Cereals and cereal by-products tend to have a low buffering capacity. Organic acids reduce the buffering capacity of the diet, which is critical to effective enzyme activity and control of microbial proliferation. Blank et al.,9 observed that increasing the buffering capacity from 23.5 to 56.7 decreased the ileal amino acid digestibilities up to 10%. A recommended buffering capacity value for poultry starter diets is 0 to 10.8 Acid- binding capacity, pH and B-value of some ingredients are shown in Table 2 and Table 3, respectively.

Mode of action of organic acids
Like antibiotics, organic acids have an antimicrobial activity. The acids can penetrate the bacterial cell wall and disrupt the normal actions of certain types of bacteria including Salmonella spp, E. coli, Clostridia spp, Listeria spp. and some coliforms. Therefore, reduction in numbers of some species of the normal intestinal bacteria as well as pathogenic bacteria can occur in animals fed organic acids.6
Antibacterial spectrum of organic acids
Each acid has its own spectrum of antimicrobial activity. For example, sorbic acid is better known for its antimold activity, but lactic acid is more effective against bacteria. Formic acid, propionic acid and HMB have broader antimicrobial activities and can be effective against bacteria and fungi, including yeast.10,11 It has been reported that blends of some acids have synergistic antimicrobial activity in vitro.12 The MIC for acetic, butyric, lactic and caprylic acid in E. coli are less than 4 g/l, but this same bacterium is approximately 10-times more resistant to malic, tartaric and citric acid (Hsiao and Siebert, ).
Using Organic Acid in poultry nutrition
One of the first reports of improved broiler performance was for formic acid, when diets were supplemented with single acids.13 Subsequently, Izat et al.,14 reported reduced levels of Salmonella spp. in carcass and caecal samples after including calcium formate in broiler diets. Izat et al.,15 showed that buffered propionic acid could be used to counteract pathogenic microfelora in the intestine of broiler chickens, which resulted in a significant reduction in carcass contamination with Escherichia coli and Salmonella spp. The use of pure formic acid in breeder diets reduced the contamination of tray liners and hatchery waste with S. enteritidis.16 Organic acids have strong bacteriostatic effects and have been used as Salmonella-control agents in feed and water supplies for poultry.17 Acidification with various weak organic acids to diets such as formic, fumaric, propionic, lactic and sorbic acid have been reported to decrease colonization of pathogen and production of toxic metabolites, improve digestibility of protein and of Ca, P, Mg and Zn and serve as substrates in the intermediary metabolism. Several studies demonstrated that supplementation of organic acids to broiler diets increased growth performance, reduced diseases and management problems.18‒20 Hinton & Linton21 studied salmonella infections in broilers using a mixture of formic and propionic acids. They demonstrated that 6kg/t (0.6%) of this organic acid blend was effective in preventing intestinal colonization with Salmonella spp. from naturally or artificially contaminated feed. Improvements in broiler performance and hygiene in response to organic acids are often reported. However, an important limitation is that organic acids are rapidly metabolized in the foregut (the crop to the gizzard), which will reduce their impact on growth performance. Double salts of organic acids, such as potassium diformate and sodium diformate, which reach the small intestine, have been shown to have a significant impact. Selle et al.,22 demonstrated the effects of potassium diformate at dosages of 0.3-1.2% until 35 days post-hatch on nutrient utilisation (Figure 5). Furthermore, diformates reduced numbers of pathogenic bacteria (Salmonella, Campylobacter and Enterobacter) in broiler chickens and increased numbers of Lactobacilli and Bifidobacteria.
Mikkelsen et al.,23 showed that 0.45% potassium diformate reduced mortality caused by necrotic enteritis (Clostridium perfringens). After the necrotic enteritis outbreak (day 35 of the trial period), KDF significantly reduced the number of C. perfringens in the jejunum, in agreement with results showing that formic acid inhibits growth of C. perfringens24 in vitro. It is possible to decrease chicken carcass and egg contaminations by adding organic acids to the feed or drinking water at appropriate times. Medium-chain fatty acids have more antibacterial effect against Salmonella than short-chain fatty acids. The antibacterial effect of these acids is species-specific. Bacteria that are unable to decrease intracellular pH accumulate organic acid anions in accordance with the pH gradient across their cell membranes. The short-chain fatty acid butyrate specifically down-regulates expression of invasion genes in Salmonella spp. at low doses. Also medium-chain fatty acids and propionate decrease the ability of Salmonella spp. to invade epithelial cells, in contrast to acetic acid.25
Several studies support the statement that the addition of citric acid to broiler rations improved weight gain,26,27 increased feed consumption,28 and improved feed efficiency.29 Its addition, its use increased retention of phosphorus,30,31 tibia ash,32,33 and toe ash34 in broiler chicks. It also decreased pH of cecal digesta, crop and gizzard,35 and intestine36 in broiler chicks and improved immune responses by broilers.29,37
An experiment was carried out by Yesilbag & Colpan38 determine the effects of dietary organic acid supplementation (0.5, 1.0, and 1.5 %) on performance (bodyive weight, feed intake, feed efficiency, and egg production), egg quality and blood parameters in laying hens. The hens were fed with diets (17% crude protein and kcal/kg metabolic energy) supplemented with 0% (control group), 0.5%, 1.0%, or 1.5% organic acid mixture (formic and propionic acids, and their ammonium salts) during 18 weeks. The dietary organic acid supplementation did not significantly affect growth performance (body weight, food consumption) and egg quality parameters, but markedly improved the egg production, by accelerating the laying capacity and prolonging the laying period in 24-28 week old and 36-38week old hens respectively and the feed efficiency at a lesser extent. Serum total protein (p<0.01) and albumin concentrations (p<0.05) as well as AST activity (p<0.05) were significantly increased, whereas the other tested serum parameters (ALT activity and cholesterol, HDL, triglyceride, VLDL and total lipid concentrations) were unaffected. They concluded that dietary supplementation with organic acids and their salts could be used in layer hens with benefit on egg production and protein metabolism efficiency. Some previous results of using organic acid in broilers are listed in Figure 6.3
Acidifying drinking water of poultry for the first 7 d of life, when the birds are first placed into the house, is considered critical, because the crop and intestinal microbial morphology would still be under development. Maintenance of low crop pH by the lactic acid bacteria (LAB) in newly hatched chicks and poults is critical. The acidified drinking water provides a second layer of protection to the LAB and helps to establish them as a part of the crop’s normal ecology. Once the crop’s LAB population has been established, the bird will be able to maintain a low crop pH on its own as long as feed is available.39,40
