Abstract:
Animal husbandry is considered a substantial part of agriculture
which is important for the economic development of a country. The
local potential for the livestock sector has remarkably developed in the
past few decades with the introduction of technological advancements.
ldentifrcation and traceability of livestock populations evolved as critical
points in the production chain. Molecular marker-based genetic studies
have addressed the preliminary complications of the livestock freld. The
lntended objective of genetic studies is to select and maintain superior
trarts which have a direct impact on economrc value. ln that regard' the
application of genetic markers has a signifrcant role. RFLP, SCAR, AFLP,
SSR, ISSR, EST, RAPD, STR, SCoT, and STS markers are prominently
used despite animal identifrcabon and traceability, determlnation
of genetic distance, sex determination, parentage determinalion,
genetic conservation, gene mapping approaches in the livestock field.
The present review is a critical study of current molecular biological
techniques and their versatile appllcations in animal identification and
traceability approaches and possible improvements of the available
techniques to address the maior concerns in the freld.
