Farmers Encouraged to Update Hay and Straw Directory

The Iowa Department of Agriculture and Land Stewardship offers a free directory to connect farmers who sell hay or straw with local producers who are interested in purchasing it. Organizations associated with promoting and marketing hay and straw can also access the free, online tool. The Department encourages users to update their listing every year.

Movement Risks Checklist for Organic and Alternative Livestock

Items moving on and off your farm or ranch can bring disease. Recognizing movement risks can help you prevent them. The Livestock Project has created a Step 1: Movement risks checklist that can help you recognize and think about the types of movements that happen on your operation. In addition, the checklist can help you take the necessary steps to make those movements as safe as possible. The movements themselves and how often they occur are the key ideas to keep in mind. Major categories of movement risks are – animals and animal products, vehicles and equipment, visitors and personnel, and wildlife and pests.

Fly Control

With summer in full gear it is a good time to evaluate how your fly control program is working. When horn fly numbers are greater than 200 flies per animal we see significant production losses associated with blood loss and decreased feed consumption. Numbers of face flies and stable flies are harder to assess because they only spend a small amount of time feeding on cattle but are still significant pests.

Flood Recovery for Pastures

Flood waters are receding, but the challenges in recovery for farmers and livestock producers are just beginning. Beth Doran, Iowa State University Extension and Outreach beef specialist, recommends producers get out in their fields as soon as possible. "Beef producers should assess the damage to pastures and hay ground, then check out possible disaster assistance," she said. Doran advised cattlemen to look for three things in their assessment - debris, silt on the forage, and thinned or dead forage plants.

Solving Ventilation Challenges in Calf Production

Raising dairy beef calves has been a challenging, yet rewarding experience. Over the course of the past 16 months raising baby calves, there have been many things that I have learned. There is no system that works for everyone in every situation, but I hope that sharing my experience can help you on your farm.

The number one necessity in successfully raising calves is proper ventilation. I raise calves in a retrofitted 60x40x40 hayshed. The hayshed sits north and south. There are doors on the south end and east side of the shed. There are also two, 4x4 foot fans that we installed on the north end that suck air through the hayshed (negative pressure mechanical ventilation). None, one, or both fans can be turned on by a switch, but they have one speed. Fifty-three individual pens, that we built ourselves, can fit in this shed.

During my first group of calves in this hayshed, we started noticing that calves in the back ¾ of the hayshed were starting to develop some respiratory problems. By this time, it was late May, so the average overnight temperature was 60 degrees and day temperatures in the upper 70’s. This warm air would rise and not exchange with the lower air, and so we concluded that by the time the air flowed to the back ¾ of the shed that it was way above the calf level and not exchanging air. This allowed for the proper environment for respiratory problems to start.

We decided that there needed to be a way to baffle the air so we could get the proper air exchange. We decided to make a baffle out of silage wrap and install it in the middle of the shed. In order for it to work correctly, it had to be cut out to fit the peak of the hay shed. We measured and cut the baffle out in the yard and then installed it with plastic pieces that could help support the weight of the silage wrap on the screws, and then we screwed them into the rafters of the hayshed. The bottom of the baffle comes down to just above the calf pens. The air that is then sucked through the hayshed will run into the baffle and spread out and move to the bottom of the baffle. This allows the fresh air to exchange with dirty air, yet since the baffle is a foot and a half above the calf, it does not create a draft on the calf. As you’ll see in the above picture, we have the east doors open. The fans will pull air from the easiest source. We want to create a tunnel so that the air is even, so we now keep those doors shut.

Baffle in barnWhile we noticed that there was much better ventilation now with one baffle installed in the middle of the shed, we did notice some areas that still had dead-spots where air was not moving. Once this group of calves were weaned and moved to another pen, we made two more baffles and installed one in the front ¼ of the shed and the back ¾ of the shed.

While this system is not perfect, it has allowed us to provide much better ventilation for the calves, and we have seen a significant drop in respiratory issues once the baffles were installed.

Would this system work for you, and wondering where you can get some silage wrap? You have probably noticed the white bags full of different types of feed while you drive around Iowa. Once the feed is removed from those bags, they machine that packs them cannot usually reuse the same material. You could see if they would sell you the wrap once they are done with it.
