1. Rosie: The most famous Transgenic cow, Rosie, was created by researchers at the Roslin Institute in Scotland in 1996. She was engineered to produce human growth hormone in her milk, which can be beneficial for individuals with growth hormone deficiency.
2. Polly and Molly: These Transgenic cows were created in 1997 and 1998, respectively, by researchers at the University of Massachusetts, Amherst. They were engineered to produce human lactoferrin in their milk, a protein that has antimicrobial and immune-boosting properties.
3. Herman and Henrietta: These two Transgenic cows were created by researchers at the University of Guelph, Ontario, Canada. Herman and Henrietta were engineered to produce bovine somatotropin, a hormone that increases milk production in cows.
4. Daisy: Daisy is a Transgenic cow created by scientists at the National Institute for Animal Science in Tsukuba, Japan. She was engineered to produce a bioactive protein that suppresses the immune response, potentially making her organs compatible for transplantation into humans.
5. Bessie and Ferdinand: These Transgenic cows were created by scientists at the Institute for Animal Science, Swiss Federal Institute of Technology in Zurich, Switzerland. Bessie and Ferdinand were engineered to produce beta-casein, a protein that can potentially improve milk quality and increase cheese yield.
6. Eco: Eco is a Transgenic cow developed by researchers at the University of California, Davis. Eco was genetically modified to produce an enzyme called phytase in her milk, which can help break down phytic acid in plants, increasing the bioavailability of phosphorus for human consumption.
It's important to note that the development of Transgenic animals, including cows, is a controversial topic with ethical, environmental, and health considerations. Regulations and guidelines vary among countries regarding the creation, use, and consumption of Transgenic products.
