RNA-seq profiling of the kidney, pancreas, follicle, and uterus of laying hens supplemented with phytogenic feed additives

Phytogenic feed additives offer health benefits, improved overall performance and well-being in poultry production and provide an alternative to in-feed antibiotics. In this experiment, post-peak laying hens were fed for a period of 4 weeks either Control or Supplemental diet, a phytogenic feed additive based with essential oils from thyme (Thymus vulgaris) and star anis (Illicium verum) as well as Quillaja bark (Quillaja Saponaria). RNA sequencing was performed in the pancreas, kidney, uterus and large-white follicles of 10 birds from each dietary groups at the end of the trial.
