No, to my knowledge their breeding program is still active. Their last calves were 4 and 5 years ago, respectively. Going off of their past history, they have calves every 5-7 years, so there is no reason to think they've stopped yet. In addition, their young male is 11 years old and unrelated to 3 of their females, so it is likely he will start to breed naturally with them in due time as well.
