Managing Feed Costs in a Time of Expensive Inputs

As we enter the fall and look ahead to winter feeding months, hay prices continue to climb. With feed accounting for more than 50% of production costs, managing these expenses is critical to remaining profitable in current times. Two strategies for decreasing feed costs are: 1) extending the grazing season to reduce hay feeding; and 2) making smart hay purchasing decisions to get the most out of your investment. The grazing season can be extended with improved forage management. With cattle, the Amazing Grazing team at NCSU has coined the term "POW - The Power of One Wire." Unfortunately, many…

Small Flock Pasture Management

At weaning time, you will need your best pastures in tip top shape for your lambs to continue growing. Your free input resource must be managed throughout the late spring and summer. This can be challenging with limited equipment and modest grazing space. Rotational grazing techniques are helpful and can be complimented with proactive management. Early in the warmer seasons, cool season grasses and forbs are dominant and provide great forage. As the temperatures climb, the availability of palatable grasses and plants decline. Grasses can go to seed too quickly to graze your animals on them. Rain followed by hot daytime temperatures cause the grasses…

Weaning lambs on a small farm can be a challenging endeavor. Being limited on space and supplies, such as electric fencing, means careful planning must take place to manage the two groups separately. There are various ways to wean lambs off of their dams. The approach you choose may vary from year to year depending on the mix of ewe and ram lambs per dam, the ages of the lambs, changes in the size of the flock, available resources and even the weather.  Some folks choose to fence line wean by dividing the groups with fencing (preferably permanent) and moving…

Ewes only have two teats and hopefully raise at least twin lambs, so maintaining healthy udders and culling ewes with udder problems is important to minimize lamb losses and bottle lambs while ensuring optimal growth of lambs on your farm. Mastitis leads to lower weaning weights in lambs of affected dams, takes time and money for treatment, as well as slowing down genetic progress due to forced culling of ewes. Rates of mastitis are variable across different farms. It is important to keep track of the percentage of ewes that get mastitis each year or are culled for lumpy udders…

Pregnancy Diagnosis

There are various options for diagnosing pregnancy in sheep. The cost/benefit analysis for doing this procedure depends on what you are going to do with the information. Your reasons for doing pregnancy diagnosis will also dictate which method you want to employ. In general, the earlier in pregnancy the diagnosis is made, the larger the risk of false positive results due to early embryonic loss. If avoiding false positive pregnancy diagnosis is essential to your production, it might be better to postpone diagnostic testing so ewes are closer to 60 days pregnant before testing. Available diagnostic tests: Blood tests: Pregnancy…

Polio in Sheep: A Medical Emergency

Polioencephalomalacia (PEM or Polio) is a common disease in sheep. Unlike the human form of Polio, it is not a viral infection, but a neurological disease characterized by brain swelling that, if left untreated, progresses to degeneration of brain tissue due to pressure necrosis. Early treatment is critical to lamb survival. A deficiency in thiamine (vitamin B1) is the most common cause of Polio and is usually induced by a disruption in normal rumen function, especially acidosis. Thiamine plays a key role in glucose metabolism and proper brain function. Since thiamine is produced from rumen microbes, lambs at greatest risk…

To best express their genetic potential, sheep must be in optimal body condition. Both overly fat sheep and sheep that are too thin are not as productive as they can potentially be. Body condition scoring (BCS) enables you to identify the animals that fall outside of a preferred range. You can use this information to evaluate feeding strategies and to identify animals that are not doing well in your management system. This article will cover the use of BCS as a management tool. Links to information on how to perform BCS can be found in the reference section at the…
