<p style="text-align: justify;">Transgenic &nbsp;food &nbsp;animal &nbsp;production &nbsp;is one &nbsp;of &nbsp;the &nbsp;potential and &nbsp;need &nbsp;oriented &nbsp;research &nbsp;to &nbsp;mitigate &nbsp;the &nbsp;food &nbsp;crises &nbsp;of &nbsp;the &nbsp;world. &nbsp;In &nbsp;vitro &nbsp;gene &nbsp;silenced &nbsp;animal &nbsp;cells &nbsp;and &nbsp;making &nbsp;use of &nbsp;these &nbsp;cells &nbsp; for &nbsp;transgenesis &nbsp;one of the suitable way to produce &nbsp;productive animals. &nbsp;Myostatin is a negative regulator of muscle growth, has the potential to increase the muscle mass upon its silencing. Four Hush 29-mer &nbsp;anti- myostatin (MSTN) &nbsp;shRNA &nbsp;constructs &nbsp;were checked for myostatin &nbsp;gene silencing in caprine foetal fibroblast cells &nbsp;and &nbsp;its &nbsp;subsequent effect &nbsp;on &nbsp;basic &nbsp;helix&ndash; loop&ndash;helix (bHLH) transcription &nbsp;factors. These factors are necessary for the terminal differentiation, proliferation, and homeostasis of muscle development. Different &nbsp;shRNA constructs displayed 55.1 &nbsp;to &nbsp;91.5% (p&lt; 0.01) of &nbsp;myostatin &nbsp;silencing &nbsp;in &nbsp;caprine &nbsp;foetal &nbsp;fibroblast &nbsp;cells &nbsp;and &nbsp;upregulation of &nbsp;myogenic gene. Upregulation of 7.97 &nbsp;to &nbsp;111.67 % &nbsp;for MyoD, 77.0 % &nbsp;to &nbsp;319.47 % for myogenin, &nbsp;16.67 % &nbsp;to &nbsp;138.0 % &nbsp;for Myf5 were observed . The &nbsp;Pearson &nbsp;correlation &nbsp;established &nbsp;a &nbsp;negative &nbsp;correlation &nbsp;between &nbsp;myostatin &nbsp;and &nbsp;genes under study. &nbsp; Result &nbsp;suggests &nbsp;that &nbsp;knockdown &nbsp;of &nbsp;MSTN a &nbsp;potential approach &nbsp;to &nbsp;improve &nbsp;caprine musculatures.</p>
