Synchronisation of heat controlling heat) is desired in:

✅ Explanation:
→ Synchronizing estrus in sheep is done to bring the ewes into heat at an earlier time for breeding and thus getting lambs for a certain time period.
→ Estrus synchronization in sheep can help reduce strain on rams and provide a shorter, more consistent lambing season window to increase efficiency and reduce labor.
→ Estrus synchronization in sheep is the act of preventing ewes from cycling naturally by introducing progesterone or a progesterone derivative into the vaginal vault of the ewe. This, in turn, tricks the ewes’ body into believing that she is pregnant and keeps her from cycling normally.

📝 Additional Information:
→ Other reasons to synchronize estrus in sheep could be to group estrus to reduce strain on your ram battery, tighten the lambing season to reduce labor over a long period.
→ Once the progesterone is removed, the ewe will cycle usually within a 48-hour window, creating a synchronized estrus.
→ Proper nutrition is key for successful estrus synchronization in sheep.
→ If the ewes are too thin, they will not respond to the synchronization agent as reproduction will not replace the ewes’ natural survival instinct.
