Webinar Will Offer Tips on Out-of-Season Breeding
December 7, 2018

Sponsored in part by the American Sheep Industry Association’s Let’s Grow Program, a new webinar on Approaches to Enhancing Lambing Rate from Out-of-Season Breeding has been scheduled for Dec. 11 at 8 p.m. eastern time.

Marlon Knights, Ph.D., and an associate professor at West Virginia University, will lead the presentation. As always, Dr. Jay Parsons from the University of Nebraska-Lincoln will host the session.

In temperate regions, the seasonal nature of reproduction in sheep limits the frequency of lambing to once per year which in turn can result in significant variation in the price, quality and quantity of lamb in the market, as well as the lifetime productivity of the ewe. Overcoming seasonality by getting a proportion of your ewes to breed “out-of-season” will not only increase the average number of lambs weaned per ewe per year but can positively impact marketing of lambs.

Approaches to improve the fertility of ewes bred out-of-season will include selecting the right breeds and animals within breeds, photoperiod manipulation, melatonin treatment and the introduction of novel males (“male-effect”) in combination with or without progesterone (CIDR) pre-treatment.

Other management practices that foster improved fertility in out-of-season bred ewes include weaning lambs and improving the nutritional status of ewes prior to breeding, isolating ewes from rams prior to the breeding season, and, the use of fertile rams with high sexual activity at a high ram-to-ewe ratio.

Implementing practices to manage seasonal reproduction requires a small investment and some change in management practices. However, lambing rates that are equal to or greater than the current national average can be achieved from out-of-season breeding. Lambs derived from ewes bred out-of-season fetch higher prices and will provide consistency in the quality and quantity of lamb in the market place.
