He did get groggy but was still plenty alert. I did forget to mention, somehow, that when he came through the chute the following month he weighted in at 152lbs. I thought he was heavier but the scale is accurate. Not sure why he wouldn't go out, when collected on with other sedatives he has never been an issue. I should note that it was February, and dart was placed in the neck and not the hind quarter. No symptoms arose after the process either, feed consumption was stable.
