Why would farmers want to give their cows extra bGH?

Farmers may choose to administer extra bovine growth hormone (bGH) to their cows to increase milk production and improve feed efficiency. By enhancing growth rates, bGH can help cows produce more milk with less feed, leading to higher profitability. Additionally, it can contribute to more consistent milk supply, which is beneficial for meeting market demands. However, the use of bGH is controversial due to concerns about animal welfare and potential health impacts.
