Transgenic livestock are animals that have had genes from other species inserted into their genomes. This presentation discusses the process of transgenesis, examples of transgenic animals like cows, sheep, goats and pigs, and applications in agriculture, medicine, and industry. Some examples given are disease-resistant pigs and goats that produce spider silk protein in their milk. However, ethical issues around blurring species lines, animal suffering, and potential health and environmental risks must also be considered. With further research, transgenic animals could help address various challenges if developed and used carefully.

5. TRANSGENESIS
• Transgenesis is the process of
introducing a gene from one
organism into the genome
of another organism.
• Aim -->> to exhibit some new traits.
• Genetic code is universal.

13. APPLICATIONS
 Agricultural Applications
• Disease resistant animals (Influenza resistant pigs).
• Improving quality and quantity of milk, meat and eggs.

14. Medical Applications
• Disease model
• Enhanced Nutritional value and pharmaceuticals
• Xenotransplantation

15. Industrial Applications
• Spider silk in milk of goat
• Wool growth in sheep is enhanced.

16. ETHICAL ISSUES
• Blurring the lines between species by creating transgenic combinations.
• Use of animals in research causes great suffering to the animals.
• There may be health risks.
• There may be long term effects on the environment when transgenic animals are
released into the field.

17. CONCLUSION
• Transgenic technology is a field that is
under constant evolution.
• With proper research and careful use
the transgenic animals can go a long
way in solving several problems.
