While they are spread out to fit feed density, the following picture shows roughly 100 head working as a herd. Notice how they are all grazing in the same direction. Once we make the next pasture move at the end of next week, we will be able to wean the bigger calves at a set of pens next to a water point. Once the cows have bawled off, I will start all of the cattle up a canyon in the direction of the next pasture in the grazing plan and allow the cattle to sort themselves into two groups.
Open cattle, older calves, bulls and those in the first and second trimester of pregnancy will pick up and move out easily, while those cattle in their third trimester, calves under a month old and older thin cows with calves on them will take their time getting started. This will make it easier to instill the herd instinct into the cattle and (hopefully) keep the bulls away from the cows which are calving. (One problem with running bulls year round is that 12 to 24 hours before calving, cows change from producing progesterone to estrogen. This change in hormones causes cycling cows and bulls to seek out and ride cows beginning to calve, causing dystocia.)
