The pigs are considered to be worth studying subjects with regard to genetic engineering. Though, different experiments have so far been conducted yet the study is passing through the evolution process. The pigs altered through the genetic engineering are supposed to be more human familiar than the originals. Yes, they had the disorder to be friendly with humans but the modified pigs are highly beneficial to mankind.

The following benefits can be observed in the modified pigs:
1. xenotransplantation into humans
2. Highly familiar with humans
3. Help in production of medicine
4. Developing models for humans
5. Agricultural benefits for prevention of diseases
6. Change in composition of carcas
7. Amelioration in pigs to face heat stress
8. Highly protection of environment
9. Change in pigs behavior

The modification in the animals have been rightly cited in your article. You are absolutely right in saying that the meat consumed by the humans of pig , would be of finest quality if they are modified. I do agree with your another point that the meat would also be healthier for the people who consume pig meat a lot.

Exactly, the biotechnology has revolutionized the world through science and technology. The change in behavior of modified pigs clearly implies its importance. Besides, pigs are psysiologically analogus to mankind and anatomical in other way. I second your opinion that experiments had been firstly started from mice and now they are being carried over the mammals.

Importantly, transgenic pigs are donor organism for xenotransplantation into humans because they have many same characteristics of humans. hyperacute rejection is considered to be the biggest barrier in the xenotransplanation. Though, acute humoral xenograft rejection is also considered to be a barrier. Scientists are working in making the pigs as the best donor for transplantation of organs. They hold the view that the modification of multi transgenic pigs for clinical xenotransplantation would be the biggest challenge for them.
