Dietary Saccharomyces cerevisiae fermentation product improved egg quality by modulating intestinal health, ovarian function, and cecal microbiota in post-peak laying hens.

Saccharomyces cerevisiae fermentation product (SCFP), a postbiotic feed additive, has potential to improve animal growth and productivity. However, its effects on post-peak laying hens have not been thoroughly investigated. Therefore, this study aimed to explore the effects of SCFP on production, egg quality, intestinal health, ovarian function, and cecal microbiota in post-peak laying hens.

Benzoic Acid, , and Essential Oil Complexes Improve Ovarian and Intestinal Health via Modulating Gut Microbiota in Laying Hens Challenged with and Coccidia.

Intestinal disease is becoming increasingly prevalent in poultry production; however, the effect of BEC in laying hens challenged with and coccidia is limited. This study aimed to investigate the effects of dietary supplementation with BEC on intestinal and ovarian health in laying hens challenged with and coccidia. A total of 80 Lohmann gray hens (35 weeks) were randomly assigned to two dietary groups supplemented with BEC (0 or 1000 mg/kg).
