"Actually, in this instance we do have probably a better tracking system than was the instance in Canada. Because this is a dairy cow, they're all individually tagged"

Ann Veneman is describing the tracking system of dairy cows in the United States compared to Canada. In the United States, dairy cows are separately tagged, which allows for much better tracking of the cows. This implies that the cows can be tracked more quickly and accurately, permitting much better management of the herd. This is helpful for the farmers, as it allows them to keep better track of their cows and ensure that they are healthy and producing the very best quality milk. Additionally, it allows for much better tracking of the cows in case of disease break outs or other problems. This enhanced tracking system is beneficial for both the farmers and the cows, as it enables much better management of the herd and much better protection of the cows.
