Pregnant, late or open

cows coming in

It’s that time of year again. The cows have spent the summer on the forest, raising their calves. The calves have been weaned and now it time to decide which cows will stay and which will go. A key factor in this decision is pregnancy. The cows have also been keeping company with bulls all summer. If all went well, they are pregnant. If not, they will find a new home. Our friend and long-time veterinarian Warner McFarland came with his ultrasound machine to check each cow and call out, “pregnant,” “late,” or the dreaded “open.” Luckily, not many cows were open (i.e. not pregnant). Since all of our summer crew has departed for warmer climes, we depend on family and Chandler to get things done.

Is she or isn’t she–that is the question

It’s that time of year again. With the calves weaned, it’s time to learn which cows are pregnant, which ones are open (not pregnant) and which ones are due to calve later than we like. This keeps us from putting winter feed into a cow who is not going to raise a calf next year. Often the ones who were bred later will make a fine cow for someone on a different calving schedule, but do not fit our “program”. Our annual cycle is absolutely determined by our climate. We ranch at a high altitude, and even our low country is more than a mile above sea level. The long summer days and great soil mean that our grass is high in protein, perfect for raising strong and healthy livestock and wild ungulates. The short growing season means that we need to maximize that grass while it is available. Add to this our complicated schedule of a landscape scale rotation through private and state lands, and BLM and Forest grazing permits. This means that we need our calves to be born in a fairly small window, so that they will grow and thrive when conditions are optimal, and be a uniform size when it is time to sell them. We shorten that window for some of the cows by artificial insemination in late June. This does give us an added risk of bad weather during a shortened calving period–a risk we try to minimize by keeping them close to sheds and shelter during calving. But we will worry about that next spring. For now, we wait for Dr. McFarland’s cry of “pregnant!”, “late!” or “open!”. First he peers through the googles that show what the ultrasound machine is perceiving, then he follows up with an old-fashioned palpation if necessary. Some of the cows get vaccine, some get new eartags, and they all get a backpour for parasites. Then it’s on to the wintering grounds–just in time, for today we got our first real snow
