The modern broiler chicken has evolved under human selection for rapid growth and high breast muscle yield.  This selective pressure has also resulted in increased feed efficiency, promoting the conversion of feed into chicken mass.   Comparing the growth of the modern Ross708 broiler with a legacy line that grows with properties of meat birds in the 1950s suggests that one adaptation in the modern line has been an increase in ileal length.  This additional length would allow greater opportunity for capturing nutrients.  To better understand how this selection has affected post-hatch development, we have constructed transcriptome libraries to ileal segments from Ross 708 and a legacy (Illinois) line. These libraries were prepared were using Illumina TruSeq kits, sequenced on an Illumina HiSeq2500, processed using the Tuxedo suite and analyzed with JMP.  Comparisons of ileal gene expression patterns between the Ross and Illinois lines will be presented.
