The provided linegraph shows the changes in population of different cow breeds over the 14 years, starting from 2000. The breeds are Angus, Holstein, Jersey and Guernsey.
Overall, most breeds increased in numbers by the end of the survey, with the exception of Guernsey that plummeted in 2012 and remained low. Jersey and Holstein had steadily grown over the years, while Angus was stable at first and only started climbing up in 2008.
The Jersey cows were the most populated breed for the whole period. 3500 cows of 2000 had risen up to 5000 in 2014. Next, Guernsey began as the second highest, yet the population was degrading slowly until the 2010. Then, the trend experienced a sudden drop from 3000 in 2010 down to 500 in 2012. The numbers continued the decrease in 2014. Angus cows fluctuated at 1500 until 2008, when the breed population started a consistent steady increase. In 2014, Angus peaked at 2200. Holstein cows were the lowest in numbers in 2000, but they increased by more than others. Eventually, Holstein matched the population of Angus at the beginning.
