Ewes are bred, the holidays are just around the corner, and for all of us with winter lambing flocks, lambing season is almost here. Over the last year, we have invested in high quality genetics to move our flocks forward and now it's important that we make sure our next generation of lambs gets off to the right start. This begins with good late gestation management. I have summarized nutritional requirements in Table 1 (think of this as nutrient demand by the animal). Requirements for energy (as indicated by total digestible nutrients) and protein increase substantially for late gestation and…

Alternative Feeds: Is Variety the Spice of Life?

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…

Protecting Your Flock from Disease

Disease is present in every flock and can reside in the animals, soil, air, and water. Producers don't often talk about illnesses affecting their sheep because they don't want the stigma of disease to reflect negatively on their flock. But producers shouldn't have to deal with the problem alone. Let's accept the fact that disease is inevitable, remove the stigma, and learn how we can prevent or mitigate disease transmission in our flocks. Disease is defined as "a condition of the living animal that impairs normal functioning and is typically manifested by distinguishing signs and symptoms." Unfortunately, sheep can't tell…

Ovine Progressive Pneumonia (OPP)

Most shepherds have probably heard of OPP as it is one of the three diseases included in the biosecurity panels that many laboratories offer. The USDA Sheep 2001 study tested over 21,000 samples from 682 randomly selected flocks country wide to collect data on the prevalence of OPP. They found that 36.4% of flocks had one or more animals that tested positive and overall, 24.2% of the animals tested were positive for OPP. Only 1.2% of the producers suspected that their animals were infected with OPP. This data is from over 20 years ago but still relevant as it shows…

The Value in the Veterinary-Client-Patient Relationship

I value my veterinarian's time and expertise. She works extremely hard, often taking appointments starting at 8 AM, and is still making phone calls on case notes at 8 PM! By law, in order for her to prescribe medications for my sheep, we need to maintain a Veterinary-Client-Patient Relationship (VCPR). I do sometimes bring sheep into her clinic for diagnosis or treatment. But I also make sure to pay for her time to visit my farm once a year, for a "well flock" visit, where she can view the whole flock and my operation. I like to schedule this at…

Udder Health in Ewes: Mastitis, Udder Scores and Management

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…

Prolapses in Sheep

There are three structures that can prolapse and be visible under a ewe's tail: vagina, uterus and rectum. Vaginal and uterine prolapses can affect ewes around lambing and will be discussed here. Vaginal Prolapse A vaginal prolapse occurs when a ewe's vagina protrudes out of her vulva. Most prolapses occur in the last few days or weeks of pregnancy. It usually starts with the ewe laying down and you just see a small little ball of red tissue protruding from the vulva that retracts when she stands up. This is the ideal time to start treatment and prevent it from…

Fall and early Winter, when the seasonal workload lessens, is often a good time to focus on our sheep supply inventory. We usually think of this when getting ready for lambing, but as shepherds we should always be prepared throughout the year for emergencies, mishaps, and unforeseen circumstances. Having some key supplies on-hand can prevent undue delay in necessary treatment and management of your flock. Following is a list of important items shepherds should have on hand, including basic handling equipment. Support Network Veterinarian – Probably the most important "tool" is a good working relationship with a veterinarian. It's best…

Summer is often the busiest time for transporting sheep since the buying and purchasing of new animals is at its peak. It is also the season for hauling animals to sales, shows, fairgrounds and livestock markets. Unfortunately, it can also be the most stressful time for animals with long trips, escalating temperatures, and crowded conditions. This article attempts to address some of those concerns and provide a plan for preparing for the trip, ways to reduce stress and keep animals healthy during transport, and how to handle new arrivals to maintain biosecurity on your farm. First and foremost, do not…
