What Is Flushing In Sheep?

What Is Flushing In Sheep? The dynamic effect or “flushing”: Ewes are gaining condition/liveweight at joining.

What does flush sheep mean? 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)

What is a benefit of flushing sheep? It is more beneficial to flush early or late in the breeding season, when ovulation rates are naturally lower, compared to the middle of the breeding season. Flushing not only increases the number of ovulations, or eggs, in the ewe, but also improves survival of the lamb embryo.

How long do you flush sheep for? Again, time is required to get ewes into the right body condition. Flushing for a two-to-three-week period is not sufficient time to get thin ewes into the ideal body condition score of 3.5. A ewe that is in body condition score of 2.5 today will need 10 weeks of good grass to get her to a body condition score of 3.5.
