“…However, the study of dietary supplementation of MCFAs, SCFAs, and their combination had no significant effect on laying performance (22). Swiaatkiewicz et al (18) reported that dietary supplementation of 0.50% VFA (0.20% formic, 0.15% propionic, and 0.15% acetic acid), 0.25% MCFA (0.125% caproic and 0.125% capric acid), and 0.30% SCFA + 0.20% VFA had no effect on laying rate, daily egg mass, egg weight, feed consumption, and feed conversion in the layer hens diet with different levels of calcium and phosphorus. Indeed, VFAs were included in the organic acids that increased egg production in layers.…”

A total of 144 Hy-Line brown laying hens were used in a 10-week trial to evaluate the effects of a microencapsulated organic acid blend with medium chain fatty acids (MCFAs) on egg production, weight, quality, fecal microflora, and nutrient digestibility in the hens. The hens were divided into four groups and different dietary treatments were given to each group. The control group received no microencapsulated organic acid blend with MCFAs. The second group received 0.05%, the third group received 0.1%, and the fourth group received 0.2% of a microencapsulated organic acid blend with MCFAs. Laying hens fed on a microencapsulated organic acid blend with MCFAs showed an increase in the egg production rate (linear, P > 0.001), in the Haugh units (linear, P = 0.010), and in eggshell strength (linear, P = 0.012; quadratic, P = 0.005). Also, the same hens had higher calcium concentrations in the blood at 35 weeks (linear, P = 0.042). The dietary supplementation of a microencapsulated organic acid blend with MCFAs increased the Lactobacillus fecal content and decreased the E.coli fecal content in the hens. In conclusion, the microencapsulated organic acid blend with MCFAs had positive effects on egg production, egg strength, Haugh units, calcium concentration, and fecal Lactobacillus and E. coli contents in laying hens. Thus, we suggest that the microencapsulated organic acid blend with MCFAs could be used as an alternative to antibiotics in laying hens.

“…Our results showed that fish fed 10 g NaDF kg −1 diet had higher serum calcium and inorganic phosphorous concentrations. The results of several studies in chicken showed that the solubility and digestibility of dietary minerals increases by dietary OA as a consequence of reducing intestinal pH that increases the activity of digestive enzymes and modifies intestinal microflora, which eventually enhances their absorption by acidic anion complexes of OA with minerals (Abdel‐Fattah, El‐Sanhoury, El‐Mednay, & Abdel‐Azeem, ; Edwards & Baker, ; Swiatkiewicz & Arczewska‐Wlosek, ).…”

This study was conducted to evaluate the effects of dietary sodium diformate (NaDF) on growth performance, gut microflora, digestive enzyme activities and immune response parameters of Asian sea bass (Lates calcarifer) juveniles. Fish with initial weight of 12.5 ± 0.4 g were fed with five experimental diets contained 0.0 (control), 5, 10.0, 15.0 and 20 g NaDF kg −1 in triplicate for 6 weeks. Fish fed diet containing 5 g NaDF kg −1 had significantly the highest final body weight and feed intake among different treatments. The gut total viable bacterial counts gradually decreased with increasing dietary NaDF level. Specific activity of chymotrypsin improved in fish fed diets administered with NaDF compared to the control group. Fish fed 5 g NaDF kg −1 diet showed the highest serum lysozyme level among different treatments. The serum classical pathway activity of complement showed higher level in fish fed diets contained 5 and 10 g NaDF kg −1 than other groups. According to break-point regression method analysis, the optimum inclusion of dietary NaDF in L. calcarifer juveniles was estimated between 4.6 and 5.1 g/kg, when specific growth rate and feed conversion ratio were plotted against dietary NaDF levels.

“…In animal production, it is known that acidification of gastric contents with organic acids improves the utilization of dietary nutrients by improving the functions of proteolytic enzymes, promoting digestion of protein and amino acids (Partanen et al . ) and the availability of minerals (Swiatkiewicz & Arczewska‐Wlosek ). However, in cats, the absence of changes in nutrient utilization by adding the acidifying agent may be because of an insufficient quantity of microorganisms capable of causing gastrointestinal infection or increased production of hydrochloric acid in the stomach, which shows that correction of the diet with an acidifier may not be required.…”

This study evaluated the effects of adding an acidifying agent based on phosphoric acid (A), a yeast extract from a specific strain (Saccharomyces cerevisiae) (Y) and the combination of these two additives in food for adult cats. A test was conducted with 24 animals (mean 3.5 years old), mixed breed, weighing 3.72 ± 0.74 kg, kept in individual metabolic cages and distributed in a completely randomized design with a 2 × 2 factorial design (with or without A 0.6% of dry matter, with or without Y 1.5% of dry matter) totalling four treatments and six replicates of each condition. The experimental period was 15 days. The A or the Y reduced (P< 0.01) the dry matter intake, but the effect was not observed when they were associated. The association improved (P<0.05) the digestibility of dry matter and ashes. The A reduced urine pH (P=0.05) regardless of the presence of the Y. There was no effect (P>0.09) on other parameters evaluated. Results of this study show that the isolated use of 0.6% A or 1.5% Y in diets for cats is not recommended. However, the association of these two additives was beneficial in increasing nutrient digestibility.
