Effect of Dietary Inclusion of Protected Sodium Butyrate on the Digestibility and Intestinal Histomorphometry of Commercial Laying Hens

Abstract: The objective of this study was to evaluate the effects of dietary inclusion of protected sodium butyrate (PSB) on the intestinal development and feed nutrient metabolizability of commercial laying hens. The birds started to receive the treatment rations at 58 weeks of age. At 76 weeks of age the laying hens were distributed in a randomized block design to four treatments (0, 105, 210 and 300 g t -1 / PSB), six replicates, and two birds/replicate. The nitrogen balance (NB), ether extract balance (EEB), dry mat… Show more

“…Liu et al (2017) found higher ileal digestible energy and energy digestibility coefficients with the use of PSB (500 and 1000 g/t), at 42 days of age, in comparison to the control treatment. Pires et al (2020) verified that the apparent metabolizable energy and the apparent metabolizable energy corrected for nitrogen increased linearly with increasing protected sodium butyrate levels (0, 105, 210, and 300 g/kg) in the diet of commercial laying hens. According to the authors, the improvement observed may be related to the action of proteginous sodium butyrate in the intestine, stimulating the secretion of pancreatic enzymes, as well as the increase in the height of the duodenum and jejunum villi, favouring the increase in metabolizable energy (AME and AMEn).…”
