abstract
Activin Receptor Type-IIA (ACVR2A) is a member of TGF-β super family, which is receptor for MSTN playing inhibitory role in regulating muscular growth in chicken ^[1]. Expression profile of ACVR2A gene was studied in two contrasting lines of chicken viz. control broiler line (CB) having faster growth rate and control layer line (CL) having slower growth. We conducted experiment during post-hatch stage from day 1, day 14, day 28, day 42 and day 56 of age. Expression of ACVR2A gene in pectoral muscle ranged from -0.43 ±0.71 to 1.26±0.71 in CB and 2.13 ±0.71 to 6.29 ±0.71 in CL line. ACVR2A gene expressed differently in both CB broiler and CL.
