Biotechnology in Animal Science
1. Examples of
biotechnology in
Animal Science:
• a. Animal cloning –
• 1) For product uniformity such as
drumstick uniformity in the poultry
industry.
Animal Cloning
• 2) Saving endangered species – Even
with the best conservation efforts,
whole species of animals continue to
disappear. If new animals could be
reproduced from the tissue of the few
remaining animals, many endangered
species might be saved
Animal Cloning
• 3) Research purposes - probably the
greatest advantage of cloned animals
is their usefulness in research
studies. Genetically identical animals
are better for research studies that try
to isolate one variable.
Animal Cloning
• b. Improving animals’ performance
through manipulation of genes.
These techniques are not as well
developed yet (3.02).
2. Examples of biotechnology
in Animal Reproduction and
Production
• a. BST (Bovine somatotropin) – A hormone
produced in the pituitary gland of cattle
that increases milk production. Through
the method of gene splicing genetic
material into E. coli bacteria, the hormone
is produced at relatively low cost. If dairy
cows are given a supplementary dose of
BST they will produce more milk.
• b. Artificial Insemination (AI) – This
process involves the introduction of
the male sperm into the reproductive
tract of a female by means other than
the natural mating process. Most of
the cows in the dairy industry are
produced through AI.
• c. Embryo Transfer – The transferring of
embryos from one female to another. With
embryo transfer, one female can produce
many calves in a year due to a process
known as superovulation which causes the
donor animal to release several eggs
instead of just one. A superior female can
be fertilized by genetics from a superior
male and the resulting embryos implanted
into inferior female animals.
