Throughout the year you make decisions to support or improve performance, but are there areas in your operation where you are overlooking some lost opportunities? Lost opportunities are those areas that could be tweaked to further improve production or performance. Let’s take a look at the breeding season to determine if there are opportunities to improve performance in that area.
A large factor that affects profitability in a sheep operation is the lamb crop. This involves anything from birth weights to growth to efficiency. Breeding season is a critical time so that we insure not only that ewes get pregnant, but that they also produce twins. We not only want high conception rates, but those conception rates need to be high during the first heat cycle.
Prior to breeding season, rams should be Continue reading

Mastitis in Small Ruminants:
What is mastitis?
Mastitis in goats and sheep, similar to cows, is defined as inflammation of the mammary gland and can occurs due several factors, which may be infectious or not and may present in clinical or subclinical form. In clinical mastitis, it is possible to observe the signs of inflammation, such as: Continue reading

Shearing sheep prior to lambing improves flock productivity. Shepherds have some simple ways to capitalize on one of the best lamb and wool markets the American sheep industry has seen. One of them is shearing sheep. It can have tremendous impacts on flock productivity, according to Reid Redden, North Dakota State University Extension Service sheep specialist. He recommends sheep producers have their sheep shorn 30 to 45 days before anticipated lambing for several reasons, including: Continue reading

Last Tuesday evening, Susan Schoenian, Sheep and Goat Specialist from the University of Maryland Extension, presented a webinar entitled: Replacement Ewe Selection and Culling of Underperforming Ewes. The webinar was sponsored by the Let’s Grow Committee of the American Sheep Industry Association.
Susan has been with Maryland extension since 1988 and is a sheep producer herself. Susan emphasizes that it is the ewe that makes the money on an operation and therefore it is critical to assess the selection and culling criteria of your flock. Selection of the highest quality females is important in securing a progressive flock. She also expresses that any ewe that fails to raise a lamb (i.e. failure to conceive or does not raise the lamb) should be culled from the flock regardless of her status. To listen to Susan’s seminar, please follow the link provided below.

To achieve maximal fertility, rams should be physically examined for reproductive fitness to detect abnormalities that may affect breeding performance. A breeding soundness examination can be completed before breeding season. The scrotum and its contents as well as the penis and prepuce must be carefully examined. The size and symmetry of both testes and epididymides should be assessed, and both testes should be firmly palpated for consistency and resilience. Semen can be collected and evaluated to check potential sires, particularly in ram lambs. All screening procedures should be done Continue reading
FDA Announces the Approval of a New Product for the Management of Reproduction in Sheep
November 16, 2009
The Food and Drug Administration (FDA) today is announcing the approval of EAZI-Breed CIDR Sheep Insert (progesterone solid matrix) for induction of estrus in ewes (sheep) during seasonal anestrus. This progesterone Continue reading

Reproductive performance is an important factor in determining profitability in the sheep flock. Most breeds of sheep have seasonal breeding patterns and the majority of flocks in Ohio are spring lambing. In this scenario, the peak fertility of the ewe is from late September through November. The breeding season will extend Continue reading
