“…The results of the current study with respect to these parameters are in agreement with findings obtained previously (Salgado et al, 2011;Wong and Zahari 2009). Previous research found that different OAs, such as lactic acid, butyric acid, formic acid, fumaric acid, and citric acid, and different levels of these acids have different effects on laying performance parameters in poultry (Martinez et al, 2004;Nezhad et al, 2008).…”

The objective of the current study was to evaluate the effects of different levels (1.5, 3.0, 4.5 g/kg) of organic acid mixture (OAM) (60% formic acid, 20% propionic acid, and 20% soft acid) supplementation in the diets of laying hens on egg production, egg quality parameters, and intestinal histomorphology. Seventy-two Lohman strains of layers (26-week-old) were divided into four treatment groups. The hens were fed either a control diet or the control diet supplemented with 0, 1.5, 3 or 4.5 kg/t level of OAM from 26 to 38 weeks of age. The OAM supplementation did not affect feed consumption, egg production, egg weight, feed conversion ratio and body weight. Except for yolk index none of egg quality parameters and metabolic profile were affected by the dietary treatments. Inclusion of OAM into the basal diet increased villus height (quadraticaly), villus weight (quadraticaly), and tunica mucosal width (linearly) eexcept for crypt depth. Based on the results, dietary supplementation with OAM containing 60% formic acid, 20% propionic acid, and 20% soft acid appears to exert neither positive nor negative effects on laying performance, egg quality parameters, or serum blood parameters. But the OAM supplementation into basal diet had a positive effect on the intestinal histomorphology except for crypt depth.

“…Rations and some animal raw materials are possibly the most important sources of contamination by pathogen microorganism in poultry. OAs have also been used as food preservatives (Dibner and Buttin 2002;Salgado et al, 2011). Furthermore, OAs added to feed can lower the gastric pH.…”

“…Nourmoham- (2012) showed that inclusion of 60 g kg −1 CA decreased BW, BW gain and plasma P concentration. Salgado et al (2011) concluded that addition of 50 g kg −1 CA into diet also promotes the growth performance of young broiler chickens; however, CA increased serum AST levels and decreased ALT activity. Islam (2012) reported that the dietary inclusion of CA at 7.5 % did not cause any signs of toxicity but significantly suppressed the growth of the birds.…”

Abstract. Citric acid (CA) is commonly used in poultry diets to promote growth by acidifying the gastrointestinal contents, improving nutrient digestibility, and reducing pathogen loads; therefore, this study was conducted to demonstrate the effects of 0, 30 and 60 g of CA per kilogramme of diet on productive performance, selected blood metabolites, immune response and certain gut-related variables in broiler chickens using 150, 7-day-old Ross 308 male broiler chicks in five replicates of 10 birds each per diet. Growth performance, daily feed intake and tibia phosphorous (P) retention were significantly improved by the diets containing 30 g kg −1 of CA (P < 0.01) but were suppressed as CA increased to 60 g kg −1 . Dietary CA increased proventriculus, gizzard and ileum percentage and villus length, crypt depth and goblet cell number in duodenum, jejunum and ileum as well as ileal digestibility of crude protein, apparent metabolisable energy and total phosphorus while it decreased the pH of contents in the gut segments concerned (P < 0.01). Diets containing 60 g kg −1 of CA significantly reduced plasma P and Fe levels as well as cholesterol level and Alkaline phosphatase activity (P < 0.05) while increasing the aspartate aminotransferase and lactate dehydrogenase activities (P < 0.01) in the blood serum of the birds at day 42 of age. The percentage of bursa and thymus was greater in the birds fed on diets containing 60 and 30 g kg −1 of CA, respectively (P < 0.01). It was concluded that inclusion of 60 g kg −1 of CA in the diet resulted in a severe reduction in performance, nutrient digestion and absorption and liver dysfunctions in broiler chickens, a phenomenon we call as acidic stress.

“…In four previous experiments (Paul et al ., 2007;Samanta et al ., 2008;Panda et al ., 2009a;Salgado-Tránsito et al ., 2011), 6 out of 10 organic acid-supplemented groups showed pH reduction in the proventriculus compared with the control groups. However, the reduction achieved statistical significance in only one experiment (Panda et al ., 2009a).…”

“…Regardless of the inclusion levels of citric acid, half of the acid-supplemented groups reported significant increase in body weight gain (Chowdhury et al ., 2009;Haque et al ., 2010;Nourmohammadi et al ., 2010;Salgado-Tránsito et al ., 2011). However, only two experiments reported significant improvements in feed intake (Haque et al ., 2010;Nourmohammadi et al ., 2010) and feed efficiency (Chowdhury et al ., 2009;Salgado-Tránsito et al ., 2011). It is postulated that excessive amounts of dietary citric acid inclusion may compromise performance because two experiments using 60 g/kg citric acid in diets reported significant decreases in body weight gain.…”

SummaryThe objective was to summarize and describe the possible mode of action of dietary organic acids and their effects on growth performance of broiler chickens. Previous experiments have suggested that dietary organic acids decrease pH in diets and subsequently reduce pH in the proximal and distal intestine, increase nutrient utilization, and inhibit pathogenic bacterial growth in the gastrointestinal tract (GIT). The degree of pH reduction is usually greater in the upper part of the GIT (crop, proventriculus, and gizzard) than in the lower part of the GIT (duodenum, jejunum, ileum, and cecum). Bactericidal effects of dietary organic acids have been observed for pathogenic bacteria and even for beneficial bacteria to some extent. However, few significant results regarding bacterial modulation in the GIT have been reported. Dietary organic acids can improve dry matter and protein utilization in some experiments, but the extent of improvement in nutrient utilization is smaller than has been anticipated. Growth performance is likely improved, but results have been inconsistent due to variations in sources and inclusion levels of dietary organic acids. Differences in other dietary components and experimental environments among previous experiments likely contribute to the variable results. This review suggests that the effects of dietary organic acids on broiler chickens are not fully understood. Further experiments are required to reliably demonstrate the mode of action of dietary organic acids and their growth-promoting effects on broiler chickens. Keywords: acidifiers, gastrointestinal pH, growth performance, microbial population, nutrient utilization. ResumenEl objetivo fue resumir y describir el posible modo de acción de los ácidos orgánicos en la dieta y sus efectos sobre el crecimiento de los pollos de engorde. Experimentos previos sugieren que los ácidos orgánicos dietarios disminuyen el pH de la dieta y posteriormente reducen el pH en el intestino proximal y distal, aumentan la utilización de los nutrientes, e inhiben el crecimiento de bacterias patógenas en el tracto gastrointestinal (GIT). El grado de reducción del pH es generalmente mayor en la parte superior (buche, proventrículo y molleja) que en la parte inferior del GIT (duodeno, yeyuno, íleon y ciego). Se han observado efectos bactericidas de los ácidos orgánicos sobre bacterias patógenas e incluso sobre bacterias beneficiosas en cierta medida. Sin embargo, se han reportado algunos resultados significativos con respecto a la modulación bacteriana en el GIT. Los ácidos orgánicos en la dieta pueden mejorar la utilización de la materia seca y la proteína en algunos experimentos, pero el grado de mejora en la utilización de los nutrientes es más bajo que lo esperado. El crecimiento probablemente mejora, pero los resultados han sido inconsistentes debido a las variaciones en las fuentes y a los niveles de inclusión de los ácidos orgánicos en la dieta. Las diferencias en otros componentes de la dieta y entornos experimentales entre los ensayos anterio...
