While this article focuses on solar grazing, the principles discussed are relevant to all low-input, grass-based production systems. This article was originally published in the August 2025 issue of the Sheep Industry News and is reposted with permission. The rise of agrivoltaics—where solar energy production coexists with agricultural practices—has created new opportunities for sheep producers across the United States. As solar developers seek sustainable vegetation management solutions, sheep have emerged as an ideal partner, offering cost-effective and environmentally favorable grazing services. However, success in this dual-purpose system depends on more than just turning sheep loose under panels.A balanced approach to…

Have you felt pretty beat up by the heat when you work outside for long hours in the summertime? Well, let me tell you that the summer heat does not only affect us, but also our flock. Imagine that you are training for a marathon at 100 degrees Fahrenheit with a quilted puffer jacket on. That is exactly how our animals feel when experiencing heat stress conditions. Heat stress is defined as when the ambient temperature and relative humidity increase to a point where it affects the animal’s capacity to dissipate their internal heat to the exterior, causing an increase…

Sheep GEMS News Brief 9 – January 2025 A nationwide survey conducted in 2011 by the USDA APHIS estimated that 14% of U.S. ewes (402,000 head) are culled each year. Of ewes culled, 56% are removed for old age. Culling for age is a good thing as these ewes have been productive for years, but we have limited resources and need to make room for younger, genetically superior females. The flip side is that 44% of cull ewes leave the flock early, which is not a good thing. The most common reasons for culling ewes prematurely are failure to lamb…

From the perspective of a long-time, full-time farmer, this article will address the topic of mature ewe size. As we seek to improve the growth and performance of our lambs, we are also producing larger adult animals. The harder we push for improved growth and performance, the faster we accelerate the trend toward bigger ewes. Big sheep catch our attention. We may have an inborn human preference for bigger animals. The bigger sheep seem superior to the small ones. They win lots of ribbons at the sheep shows. A majority of my seed stock customers purchase the biggest animals in…

Winter grazing for livestock offers numerous benefits that extend beyond traditional feeding practices. This article explores the advantages of winter grazing, including improved animal performance, enhanced animal health, reduced labor for farmers, and ultimately, improved profitability. Improved Animal Performance: Winter grazing allows animals to continue their natural behaviors which limits exposure to mud and pathogens that often occur at hay feeding stations. Research by Johnson et al. (2018, "Effects of Winter Grazing System on Cow Performance and Pasture Productivity") demonstrates that properly managed winter grazing can maintain or even enhance body condition in livestock leading to improved reproductive performance and…

In 2022, the Southwest Virginia Agricultural Research and Extension Center hosted its 10th ram test and sale. Over the years, the program has developed a strong reputation for the development and identification of superior rams for growth and parasite resistance in a forage-based environment. Historically, the test has included rams from NSIP flocks and some rams from flocks not enrolled in NSIP (non-NSIP). The 2022 test and sale data were analyzed to explore the impact of NSIP enrollment on ram performance and value in the program. The 2022 test included 119 rams from 10 states. Rams were delivered in late…

When it comes to sheep feed…it depends. With staggering increases in feed costs due to inflation, supply chain disruptions, impacts of international conflicts affecting energy, grain and fertilizer production along with regional weather events, now might be a good time to investigate alternative feeds. Alternative feeds are those that are not commonly used on a regular basis as part of the usual livestock feed ration and are often cheaper than typical feed, such as corn and soybeans. Availability and cost of certain alternative feeds will vary based on geographic region so it pays to do some research on what might…

For a small producer, identifying a hay farmer that suits your needs each and every year can be an invaluable asset to your farm. Building and nurturing that relationship may mean you have access to hay during unforeseen events, such as drought or shortage. Creating that relationship gives you an understanding of what you are buying. It allows you to become actively involved in the production of your animal's diet for a good portion of the year. The benefit to your hay farmer is simply knowing that you are coming back every year. It's easier to produce a product for…

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…

Breeding season is here and if you want to add lambs to your flock next year you are going to need a ram. Timing your lambing to suit your schedule requires you to keep a ram separate until you're ready to introduce him to your ewes. Keep in mind, rams of different ages have different feed requirements for maintenance and must be housed with companions as they too, need a 'flock' to keep stress low and maintain a calm disposition. Keeping rams and ewes separate requires maintaining two different groups most of the year. A little creativity may be necessary…
