Detailed explanation-1: -Researchers have genetically engineered bacteria to produce bovine growth hormone. This hormone can be given to cows in order to increase their milk production. How will increasing a cow’s milk production most likely impact society? Milk can be supplied to more people using fewer animals.
Detailed explanation-2: -All milk contains small amounts of the naturally occurring bovine growth hormone, also known as bovine somatotropin (BST). This hormone in cattle helps regulate growth and milk production.
Detailed explanation-3: -In 1999, Health Canada banned its use and sale in Canada due to concerns over animal health and welfare. Studies showed that cows receiving rbST injections were at risk of health issues (mastitis and lameness). To this day, rbST cannot be used for dairy farming in Canada.
