Some Ideas About Crossbreeding Sheep

Why do commercial producers crossbreed sheep-or any animal, for that matter? There are two reasons. First, no breed of sheep is best in all characteristics. If a producer combines the best characteristics of several different breeds, they have a chance to get a better combination than he could get with any one breed. This is called breed complementarity.

As an example of this, the Finnish Landrace sheep are extremely early maturing and have a very high lambing rate. They do, however, have relatively poor conformation, and the wool is of poor quality. Rambouillet sheep, on the other hand, produce excellent wool, but they do not have a high lambing rate and they are slow maturing. Neither of these two breeds excels in growth rate and carcass conformation. The meat breeds are also used to sire market lambs because they are growthier and produce excellent carcasses. The meat breeds are not well adapted to many conditions under which sheep are raised, however.

Another reason for crossbreeding is that Continue reading

Lambing and Kidding Assistance Survey

Jacci Smith, OSU Extension Educator ANR/4-H, Delaware County

As your lambing and kidding season wraps up, we are hoping that you could help us better understand the prevalence of birthing assistance in small ruminants. Please take this quick survey to let us know your level of birthing assistance in your operation- even if it was zero. https://go.osu.edu/lkassist

Licking County Hosting Lambing and Kidding School

2022 Licking County Lambing and Kidding School

OSU Extension in Licking County and the Licking County Sheep Improvement Association are providing a Lambing and Kidding School on Thursday, October 20th from 10:00 a.m. to 1:00 p.m. There will be no fee for this class, but we do require registration by October 17th.  Call 740-670-5315 to make your reservation. The location will be the Licking Valley Church of Christ at 158 Dayton Rd NE, Newark OH 43055.

With lambing and kidding seasons approaching, now is the time to prepare. Our class will discuss nutrition needs for nannies and ewes, pregnancy management from beginning to end and delivery techniques using hands on birthing simulators. Lunch will be included!

Flushing The Ewe Flock: Is It Beneficial?

Anita O’Brien, Sheep and Goat Specialist, Ontario Ministry of Agriculture, Food, and Rural Affairs
(Previously published online as an OMAFRA publication: February 11, 2010)

The practice of increasing nutrient intake and body condition prior to and during breeding is called flushing. Its purpose is to increase the rate of ovulation and, hence, lambing rate.

The response to flushing is influenced by:

  • age of the ewe (mature ewes show a greater response than yearlings)
  • breed (prolific breeds are least responsive)
  • body condition (thin ewes respond more than those in above- average condition)
  • stage of the breeding season (greatest response is seen early and late in the breeding season).

Flushing is especially beneficial for Continue reading

Nutritional Considerations for Flocks During Breeding Season

Jaelyn Quintana, South Dakota State University Extension Sheep Field Specialist
(Previously published online with South Dakota State University Extension: November 23, 2021)

Managing nutrition during breeding season is critical for improving lambing rates, but it can often be a challenge. When breeding for spring-born lambs, forages are declining in nutritional value while nutrient requirements for sheep are increasing. Fall lambing requires breeding when heat can challenge conception. Regardless of the time of year, it’s important to keep ewes and rams in mind before, during and after breeding season. Prior to and throughout breeding, many producers utilize flushing to increase ovulation rates. During the breeding season, rams are working hard to service ewes in heat while attempting to meet their own nutritional needs. Increasing the flock’s plane of nutrition continues to play an important role in ewes by reducing early embryonic death and helping rams recover after breeding.

Ewe Management
Success of breeding is largely dependent on nutrition. Simple management techniques, such as Continue reading

Small Ruminant Production: Are CIDRs Reusable?

Dr. Brady Campbell, Assistant Professor, OSU State Small Ruminant Extension Specialist
Tim Barnes, OSU Extension Educator ANR, Marion County
Dr. Alvaro Garcia-Guerra, Assistant Professor, OSU Reproductive Physiology

Whether it’s at the state fair or local livestock auction, a conversation that commonly occurs among producers revolves around the success rate of their breeding programs. In New Zealand during the late 1980s, a controlled internal drug release (CIDR) was developed and released for intravaginal release of progesterone (P4). Since then, estrous synchronization has improved on-farm production efficiencies that can assist in grouping lambing dates, breeding ewes out-of-season, or can serve as a crucial step in the implementation of artificial insemination.

Let’s Review the Basics Continue reading
