The present experiment was carried out to determine the effect of dietary supplementation with gystor acid and sodium butyrate on selected egg production parameters, egg quality and intestinal morphology and function in laying hens.
A total of Lohmann Brown laying hens at 48 weeks of age were randomly assigned to three dietary treatments 9 replicates of 16 birds each. The hens were housed in three-tier battery cages for 24 weeks.
All birds were fed on iso-nitrogenous and iso-caloric diets in mash form, and had free access to water.
The number and weight fustor eggs laid, feed intake, feed conversion, egg quality, bone mineralisation parameters, histomorphological parameters of gusotr small intestine and gastrointestinal tract parameters of hens were determined throughout the experiment.
Dietary supplementation with butyric acid and sodium butyrate contributed to a significant gusotr in eggshell thickness, eggshell weight as a gustof of total egg weight, higher activity of bacterial enzymes in the caecum and higher concentrations of butyric acid in the caecal contents.
Hens supplemented with butyric acid protected with the MicroPEARL technology were characterised by higher calcium concentrations in bones and lower ammonia concentrations in the caecum. It can be concluded that both butyric acid sources had a beneficial influence on eggshell quality, tibia parameters and selected gastrointestinal tract parameters.
The type of protection MicroPEARL encapsulation technology influenced the dose of the product required to achieve the same effect.

GUSTOR BP70 (Swine) – Bupo Animal Health
Butyric acid is the primary energy source for metabolism in intestinal epithelial cells in poultry, it is necessary for proper development of gut-associated lymphoid tissue GALT and is considered to be an important growth modulator of intestinal microflora Van Immerseel et al. Subject to their type and chemical structure, organic acids may have a beneficial influence on the growth performance of broiler chickens.
Organic acids such as fumaric, propionic and butyric acids and their salts have been found to exert varied effects on egg production and egg quality parameters depending on their source, the amount of organic acids used, location, environmental conditions and the composition of the diets Gama et al. In studies by Kral et al. In other experiments, dietary supplementation with organic acids including butyric acid and sodium butyrate positively affected growth performance, feed conversion ratio, carcass quality, serum lipid profile and histomorphometrical parameters of the small intestine in broilers Garcia et al.
Soltan demonstrated that a mixture of organic acids increased egg production and improved eggshell quality in laying hens.
The objective of this study was to determine the effect of dietary supplements containing butyric acid or sodium butyrate on selected parameters of egg production, egg quality and intestine development and function in laying hens. All procedures used in this experiment were approved by the Animal Ethics Committee decision No.
The hens were bpp for 24 weeks. The diets, offered ad libitum in mash form, were formulated to meet the nutrient and energy requirements of laying hens Smulikowska and Rutkowski Both products were coated.
The birds were weighed at the beginning 48 weeks of age and at the end 72 weeks of age of the trial. Eggs were collected from each cage 6 times per week to determine the total number of eggs laid.
The average weight of eggs laid was determined by weighing eggs from each cage every two weeks. Feed intake and feed conversion were recorded at 4-week intervals. Egg quality was analysed at 4-week intervals at 52, 56, 60, 64, 68 and 72 weeks of age.
Freshly laid eggs were collected on the first day of a given period. Each time, egg quality was evaluated on 15 eggs per group selected randomly based on the average egg weight for a given experimental period. Eggshell thickness and breaking strength, yolk colour, albumen quality Haugh unit score and the percentage composition of egg components were determined.
The yolk was separated from the albumen using a Teflon spoon rolled on a blotting paper towel to remove adhering albumen and weighed on a precision balance. Eggshells were dried at room temperature and weighed on a precision balance. The percentages of albumen, yolk and eggshell were calculated relative to total egg weight.
The average of two measurements of thick-albumen height one close to the yolk and the other at the end of dense albumen and egg weight were used to compute the Haugh unit score for each egg according to the Haugh formula. Yolk colour intensity was evaluated and scored according to the Ggustor yolk colour fan 1 — light yellow; 15 — orange. On the last day of the experiment, at 72 weeks of age, 9 birds from each group were selected randomly to determine gastrointestinal tract parameters.
As soon as possible after slaughter 20—30 minutes and the opening of the abdominal cavity, gastrointestinal tract segments including the small intestine duodenum, jejunum and ileum and the caeca, were taken out in order to obtain their contents. Viscosity, dry matter content and digesta pH were determined in the small intestine. Samples of fresh caecal digesta were used for immediate analyses to determine: The supernatant fraction 0.
Viscosity values were recorded as apparent viscosity. The following substrates were used: In order to measure the activity of enzymes released from bacterial cells into the caecal environment, a reaction mixture was prepared, which contained 0.
The supernatant was used for the enzyme assay described above. On the last day of the experiment, at 72 weeks of age, 9 birds from each group the same as gusstor used in the analysis of gastrointestinal tract parameters were selected randomly to perform histomorphological analyses of the small intestine.
They were rinsed and dehydrated in a graded ethanol series, cleared in xylene and embedded in paraffin. The thickness of intestinal mucosa, villus length and crypt depth were measured on scanned HE-stained sections.
GUSTOR BP-70 and broiler performance
Five measurements of each structure were performed for each sample. On the last day of the experiment, at 72 weeks of age, 12 birds from each group were selected randomly to determine bone mineralisation parameters.
Tibia samples collected from laying hens were separated from the muscles and cartilage, and were assayed for the mean content of DM, ash, Ca and P. Feed and bone samples were analysed using the following methods: Samples were mineralised in a mixture of nitric acid and perchloric acid 3: Reference samples were prepared simultaneously with test samples.
Calcium content was determined by flame atomic absorption spectrometry acetylene-air flamewith the use of a Unicam atomic absorption spectrometer Solar, Cambridge, UK equipped with an Optimus data station, a background correction source deuterium lamp and cathode lamps Whiteside and Milner Phosphorus concentration was determined by colorimetry with ammonium gstor and with sodium gustlr and hydroquinone.
Absorbance was measured using a VIS spectrophotometer A. Body weight BW and body weight gain BWG of laying hens at the beginning and at the end of the study kg. The values of all parameters remained within the laying performance range for Lohmann Brown hens LTZ Production parameters and egg quality of laying hens.
However, it is not gustir whether the reason for the above differences was an increase in the bulk of digesta in the intestine, or an increase in tissue weight in this part of the GIT. There were no significant differences between dietary treatments in the dry matter content and pH of the small intestinal digesta. Parameters of small intestinal and caecal function. There were no differences in the activity of the analysed enzymes between groups T2 and T3. Concentrations of short-chain fatty acids in the caecal digesta.
The concentrations of butyric acid in the intestinal contents were also higher in group T3 at The highest proportion of acetic acid in the total pool of C2, C3 and C4 fatty acids was observed in group T1 In group T2, dietary supplementation had a positive effect on the parameters of the ileum.
The thickness of the glandular layer, villus height and crypt depth were higher in group T2 than in the control group and group T3, but significant differences in the above parameters were noted only between groups T2 and T3.
The results of our study indicate that dietary butyric acid sources had no significant effect on the body weights or weight gains of laying hens. Also in a study by Rahman et al. Both butyric acid sources added to the feed for laying hens contributed to an improvement in eggshell thickness and eggshell percentage of total egg weight, which could result from increased mineral and protein absorption.
SoltanRahman et al. The above differences may be due to the fact that in the cited studies the mixture of organic acids did not contain butyrate, which plays a more important role in the development of the intestinal epithelium than other organic acids. The inclusion of organic acids in poultry diets can lower gastric pH which may speed up the conversion of pepsinogen into pepsin, thus improving the absorption rate of proteins, amino acids and minerals including calcium Kaya et al. Both feed additives increased the total activity of the analysed enzymes in caecal microflora.
Higher concentrations of PSCFAs in the caecal contents of hens in groups T2 and T3 may point to higher amounts of extensively fermented deaminated amino acid residues in birds from those groups, relative to group T1.
From the physiological perspective, higher concentrations of butyric acid in experimental groups are beneficial because butyric acid is a good energy source for intestinal epithelial cells, more effective than acetic acid. In the present study, the applied dietary treatments had no effect on the histomorphological parameters of the duodenum, whereas significant differences were found between group T3 vs.
Generally, butyrate is known as the most effective energy source for epithelial cell proliferation Mroz et al. Butyric acid has been reported to be helpful in the maintenance of intestinal villus structure after coccidial challenge Leeson et al. Some studies revealed a beneficial influence of butyrate on intestinal villi and crypts in broiler chickens Antongiovanni et al.
The addition of butyric acid or sodium butyrate to layer diets did not decrease the intestinal pH. Organic acids prevent the growth of pathogenic bacteria that can negatively affect animal health Park et al.
Butyric acid reduced the amount of digesta entering the caecum, which could be due to 1 higher nutrient digestibility in the small intestine and therefore a smaller amount of digesta reaching the colon, 2 lower biomass of bacteria colonising the caecum. Higher weight of the caecal wall in group T2 could be due to better development of the mucosa in this part of the GIT.
Those findings point to a lower net rate of calcium release from the bones due to enhanced calcium absorption from the gastrointestinal tract. Hens fed on diets supplemented with butyric acid were characterised by a higher calcium content of bones and lower ammonia concentrations in the caecum. However, it should be noted that the inclusion level of butyric acid source protected with the MicroPEARL technology was considerably lower than that of protected sodium butyrate.
