Evaluation of the effect of short-chain organic acids and probiotics on production performance, egg white quality, and fecal microbiota of laying hens

Evaluation of the effect of short-chain organic acids and probiotics on production performance,... This study investigated the effect of concomitant use of short-chain organic acids (acetic acid, butyric acid, and propionic acid) and probiotics mixture on the production performance, quality parameters of eggs produced, and fecal microbiota in laying hens. The project was carried out with 320 laying hens at 47 weeks. This experiment was a fully randomized 4 × 2 factorial experiment consisting of 4 levels of organic acid (zero, 0.1% propionic acid, 0.2% butyric acid, and 0.3% acetic acid) and 2 levels of probiotics mixture (zero and 0.01%) with 5 replications and 8 laying hens per replication. The results showed that dietary supplementation with acetic acid and butyric acid increases the feed intake compared to a diet without additives. Still, supplementation of the diet with short-chain fatty acids and probiotics mixture did not affect feed conversion ratio, egg weight, egg production, or egg mass during the entire experiment period (47 to 58 weeks of age). Supplementation of the diet with feed additives did not affect egg albumen percentage, albumen index, and Haugh unit. Also, lactic acid bacteria and coliform populations have not been affected by experimental diets. The data indicated that a supplemental level of short-chain organic acids (acetic acid, butyric acid, and propionic acid) and probiotics mixture had no beneficial effects on performance, egg white quality, and fecal microbiota under the conditions of the current experiments. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Comparative Clinical Pathology Springer Journals

Abstract

This study investigated the effect of concomitant use of short-chain organic acids (acetic acid, butyric acid, and propionic acid) and probiotics mixture on the production performance, quality parameters of eggs produced, and fecal microbiota in laying hens. The project was carried out with 320 laying hens at 47 weeks. This experiment was a fully randomized 4 × 2 factorial experiment consisting of 4 levels of organic acid (zero, 0.1% propionic acid, 0.2% butyric acid, and 0.3% acetic acid) and 2 levels of probiotics mixture (zero and 0.01%) with 5 replications and 8 laying hens per replication. The results showed that dietary supplementation with acetic acid and butyric acid increases the feed intake compared to a diet without additives. Still, supplementation of the diet with short-chain fatty acids and probiotics mixture did not affect feed conversion ratio, egg weight, egg production, or egg mass during the entire experiment period (47 to 58 weeks of age). Supplementation of the diet with feed additives did not affect egg albumen percentage, albumen index, and Haugh unit. Also, lactic acid bacteria and coliform populations have not been affected by experimental diets. The data indicated that a supplemental level of short-chain organic acids (acetic acid, butyric acid, and propionic acid) and probiotics mixture had no beneficial effects on performance, egg white quality, and fecal microbiota under the conditions of the current experiments.
