Modern biotechnological tools for enhancing reproductive efficiency in livestock

Published on

Farm animals, an important component of agriculture in
Asia and other countries of the world plays a pivotal role in
agricultural economy in the form of meat, milk and drought
power. This important animal resource needs to be
genetically improved owing to considerable dependence
of the state economy, food chain as well as the farmer’s
security upon them. The limitation to genetic improvement
imposed by inherent biological factors can be overcome
by the use of reproductive bio-techniques which aim to
manipulate reproduction - related events and/or structures
to achieve pregnancy with the final aim of producing healthy
offspring in the females. Assisted Reproductive Techniques
(ART) manipulate structures and/or events related to
ovulation, fertilization and embryo transfer. It corners
around manipulation of female/male reproductive tract
physiology, biochemistry, health and thereby longevity.
Recently developed bio-techniques used for improving
reproductive efficiency of farm animals include artificial
insemination, gamete and embryo freezing, multiple
ovulation and embryo transfer technologies, in vitro
embryo production, ovum pick-up, cloning by nuclear
transfer (NT) of embryonic and somatic cells, stem cell
biology and transgenics. Use of these techniques could
enable scientists and researchers to understand and
overcome the key issues responsible for limiting full
utilization of buffalo to improve the economy.
