Hello, I'm an expert in the field of dairy products and agricultural practices. When it comes to the question of which milk has no hormones, it's important to understand the nature of hormones in milk and how they are regulated in the dairy industry.

Hormones in Milk:
Milk naturally contains hormones because they are produced by the mammary glands of cows. These hormones are part of the physiological processes that allow for milk production. However, the concern arises with the use of exogenous hormones, specifically recombinant bovine growth hormone (rBGH), also known as recombinant bovine somatotropin (rBST), which is used to increase milk production in dairy cows.

rBGH and rBST:
The synthetic hormone rBGH/rBST was developed by Monsanto and approved by the Food and Drug Administration (FDA) for use in the United States in 1993. It is designed to stimulate the cow's production of insulin-like growth factor 1 (IGF-1), which in turn increases milk yield. While the use of rBGH/rBST can lead to higher milk production, it has also been a subject of controversy due to concerns about its effects on animal health, human health, and the quality of milk produced.

Milk with No Added Hormones:
Milk labeled as having "no added hormones" or being "rBGH/rBST free" comes from cows that have not been treated with this synthetic growth hormone. It's important to note that the FDA has stated that no significant difference in milk from treated and untreated cows and that both are safe for consumption. Nonetheless, some consumers prefer to purchase milk from cows not treated with rBGH/rBST due to personal beliefs or concerns.

Organic Milk:
Organic milk is another option for consumers seeking milk without synthetic hormones. The USDA National Organic Program has strict regulations that prohibit the use of rBGH/rBST in organic dairy production. Organic farming practices also focus on the overall health and well-being of the animals, which includes a natural diet and living conditions that are intended to be more humane compared to conventional farming.

Consumer Choice and Labeling:
Consumers have the right to make informed choices about the food they consume. In the market, look for labels that indicate the milk is "organic," "rBGH/rBST free," or "no added hormones." It's also beneficial to understand the certification process behind these labels to ensure that the product meets the standards set by regulatory bodies.

Conclusion:
When seeking milk with no hormones, consumers can opt for organic milk or milk labeled as free from rBGH/rBST. It's crucial to be aware of the different labels and what they mean, as well as to consider personal preferences and beliefs when making a choice.

Now, let's move on to translating the above information into Chinese.

The BGH used for treatment is a synthetic chemical called recombinant BGH, or rBGH, developed by Monsanto, a company based in Missouri. In 1993 the Food and Drug Administration approved the use of rBGH, or rBST, in dairy cows. Organic milk and milk with no added hormones come from cows that are not treated with rBGH.Nov 2, 2011read more >>
