“…These results are in harmony with the other workers [9,26,8,14] who reported that supplementation of organic acids in broiler chicken improved the body weight gain in broiler chicken. In the present study, the effect of dietary organic acids on body weight gain was highly significant (p<0.05) from 3 to 6 weeks of age confirming earlier results of Senkoylu et al [20]. The improvement in body weight gain might be due to direct antimicrobial effect of organic acids as reported by Ricke [18] that organic acids may affect the integrity of microbial cell membrane or cell macromolecules or interfere with nutrient transport and energy metabolism causing bactericidal effect.…”

The aim of the study was to determine the effect of dietary supplementation of organic acids on the performance, gut health and carcass characteristics of broiler chicken. Results indicated that the birds fed diets supplemented with organic acids showed significantly (p<0.05) higher body weight gains and feed conversion ratio. Maximum improvement was achieved in the group fed 3% fumaric acid in the diet. Differences in the cumulative feed consumption were non-significant (p>0.05) among all the treatment groups. Addition of organic acids in broiler diets increased the villus height in all the segments of small intestines but the differences were non-significant (p>0.05) in case of ileum. No effect (p>0.05) on carcass characteristics was observed among all treatments except for length and weight of small intestines which were significantly (p<0.05) increased in the groups fed supplemental organic acids.

“…In our study, the addition of MCFA, and the simultaneous addition SCFA + MCFA or SCFA + inulin had a beneficial effect on the selected biomechanical indicators of the tibia bones. This influence can be probably attributed to improved availability of Ca and P by virtue of a decrease in pH in the upper part of the intestine and the stimulating effect of organic acids on villus height, which was observed in broilers by Senkoylu et al (2007). It has also been proposed that organic acids (citric acid) improved Ca availability by chelating Ca and reducing the formation of insoluble Ca-phytate-complexes (Boling et al 2000).…”

“…Sacakli et al (2006) indicated that the addition of short chain organic acids (lactic + formic acid) to the diet for quail improved utilization of dietary phosphorus and increased the content of crude ash in tibia bones. Inulin or organic acids added to the diet for broilers increased the length of intestinal villus (Rehman et al 2007;Senkoylu et al 2007), which might stimulate the absorption of minerals. The aim of the experiment was to study the effect on the biomechanical and geometrical properties of tibia and femur bones when short (SCFA), or medium chain fatty acids (MCFA), or prebiotic fructans with different lengths of chain (inulin or oligofructose) are added to the layer's diet at different levels of Ca and P.…”

In an experiment conducted on caged Bovans Brown hens, the effect of diet supplementation using organic acids and prebiotic fructans on the biomechanical and geometrical indicators of the tibia and femur bones was evaluated. At 25 weeks of age, layers were randomly assigned to 14 experimental groups, each comprising 6 hens kept in individual cages. A 2 × 7 factorial arrangement, with two dietary levels of calcium and phosphorus (normal -37.0 g Ca/kg, 6.5 g P/kg, and reduced -32.5 g Ca/kg, 6.0 g P/kg), and with diets supplemented by selected additives (none; inulin, 7.5 g/kg; oligofructose, 7.5 g/kg; short chain fatty acids (SCFA), 5.0 g/kg; medium chain fatty acid (MCFA), 2.5 g/kg; SCFA, 3.0 g/kg + MCFA, 2.0 g/kg; inulin, 3.0 g/kg + SCFA, 5.0 g/kg) was used. The experiment was conducted for 45 weeks and concluded when the hens were 70 weeks old.At 70 weeks of age, reducing the dietary levels of Ca and P had decreased the bone breaking strength by 8.9% (P ≤ 0.001) and the yielding load by 5.6% (P ≤ 0.05). A similar tendency for bone breaking strength (P ≤ 0.05) and stiffness (P ≤ 0.05) was found in the femur bones. The diet with a lower level of Ca and P negatively affected the geometrical indicators of the bones such as cortex thickness (P ≤ 0.05) and cross section area (P ≤ 0.05), but had no effect on bone weight and length. Hens fed diets supplemented with oligofructose, MCFA, SCFA + MCFA or inulin + SCFA displayed a significantly higher bone breaking strength and yield load in the tibia bone than that of the control group. In the case of femurs, a positive influence of MCFA or simultaneous addition of inulin + SCFA on bone breaking strength was found. The additives had no significant effects on the geometrical indicators of either bone. It was concluded that selected feed additives which lower the pH of the diet and intestinal content can beneficially affect the biomechanical indicators of the bones of high-productive laying hens. Laying hens, bone quality, calcium, organic acids, prebiotic fructansSymptoms of osteoporosis are often observed in modern flocks of high-productive layers, especially in the second part of the laying cycle. Osteoporosis can be defined as a decrease in the fully mineralized structural bone in which Ca is mobilized from the bone in order to contribute to eggshell formation (Whitehead and Fleming 2000). The condition leads to increased bone fragility and susceptibility to fracture. The consequences of this syndrome, also known as 'cage layer fatigue', i.e., poor bone quality, weakness, deformities and breakage, spinal bone collapse and paralysis, can be an important welfare problem, causing acute and chronic pain and distress to the birds (Webster 2004). In the United Kingdom, it was found that, in the end phase of lay, 29% of caged hens had sustained one or more broken bones during their lifetime (Gregory and Wilkins 1989). A study conducted by McCoy et al. (1996) attributed 35% of mortality in commercial caged laying hens to osteoporosis. Bone breakage is also a serious prob...

“…That is in agreement with , but opposite to the findings of pelicano et al (2005) and Samanta et al (2010) who reported higher villi in the ileum as well, following supplementation of an orthophosphoric, formic, propionic acid and calcium propionate blend. Senkoylu et al (2007) made similar observations trying a combination of formic and propionic acid. The increased villus height and decreased width contributed to more extended surface area available for nutrient absorption, although the crypt depth was found decreased.…”

“…contaminated feed (Dixon and Hamilton, 1981;Thompson and Hinton, 1997). The dietary acidification was found to resemble the effect of AGps in the gastrointestinal tract of farm animals (Senkoylu et al, 2007), so, many studies, especially on swine, have focused on examining the effect and mode of action of organic acids added in the feed. In poultry production, organic acids have not gained as much attention as in swine production, because there is lack of consistency in the results and great variability in the performance (Dibner and Buttin, 2002).…”

Organic acids are studied as candidate alternatives to antibiotic growth promoters. Their action is related to the pH reduction of the intestinal digesta, affecting the gut ecosystem in numerous ways. Intestinal microbiota can be altered as a result of the remarkable antibacterial activity of organic acids and the growth enhancement of non-pathogenic beneficial microorganisms, due to exclusive competition. Antibacterial activity has been widely reported for many poultry pathogens, such as Salmonella spp., Escherichia coli, Clostridium perfringens, Campylobacter spp., both in vitro and in vivo. However, it seems to depend on many factors concerning the weak acid used and the gut ecosystem. Apart from the microbiota, diet supplementation of organic acids has trophic effects on the intestinal mucosa, modifying the morphologic characteristics of intestinal villi and crypts and maintaining epithelial integrity. Furthermore, as found recently, organic acids have anti-inflammatory and immunostimulating properties. Diet acidification increases gastric proteolysis and the utilization of proteins and amino acids, affects pancreatic secretions and mineral absorption. There are also reports for an effect on appetite and palatability of the feed. All these properties attributed to organic acids have either a direct or indirect effect on the performance and health, even though the results presented for poultry lack consistency. Nonetheless, the benefits of organic acids can have practical application in the control of clinical and subclinical conditions, but more research is needed to study these perspectives.
