While we condemn mother’s breast feeding in public places - Scientists have produced cows that make human milk. See: http://www.thehealthalert.blogspot.com/2014/07/breast-feeding-in-public-food-not-vessel.html
Scientists have created genetically modified cattle that produce "human" milk. Scientists used cloning technology to introduce human genes into the DNA of Holstein dairy cows before the genetically modified embryos were implanted into surrogate cows.
In the scientific journal Public Library of Science One researchers said they were able to create cows that produced milk containing a human protein lysozyme. Lysozyme is an antimicrobial protein naturally found in large quantities in human breast milk. It helps to protect infants from bacterial infections during their early days of life. They have produce three generations of GM cows. http://www.sott.net/article/226724-Genetically-modified-cows-produce-human-milk
