Efficacy of controlled internal drug release treatment durations on the reproductive performance, hormone profiles, and economic profit of Awassi ewes

In conclusion, although use of CIDR for 6, 9, and 12 d is efficient to synchronize estrus in ewes with similar reproductive performance, CIDR use for 6 d provided higher return and net profit than that for 9 or 12 d. CIDR use for 3 d is inefficient for estrus synchronization in ewes.
