The benefits of transgenic animals are improved welfare for livestock, better nutrition for humans and increased protection for the environment. This form of genetic engineering generally has applications in agriculture.
Transgenic animals have a gene from another species introduced into their genome, according to the Nature Education Knowledge Project. The biotechnological process of creating transgenic animals is faster than hybridizing or crossbreeding livestock. The offspring of the genetically enhanced animals can inherit the modified genetic sequence. There are several benefits from this type of modification for animals, humans and the environment.
It is possible to create transgenic animals that have a higher disease resistance than those with unmodified genomes. This feature improves the welfare of the animal and reduces problems that could decrease production efficiency for animals that provide food.
Improving the quantity and quality of nutrients in animal products made from transgenic animals can make the foods more beneficial to humans. This can benefit public health overall.
The scale of production for animal products can create environmental problems. Transgenic animals can allow for better productivity and efficiency, using less water and land. They can also be created so that livestock operations generate fewer pollutants that can harm the environment.
