Effects of breed and progestin source on estrus synchronization
and rates of fertility and fecundity in Iranian Sanjabi and Lori ewes.
All females (100.0%) from the three experimental groups submitted to estrus synchronization
were identified to be in estrus.

and fixed-time insemination in nulliparous Saanen goat.
Association of eCG with hormonal estrus synchronization
protocols can increase ovulation and pregnancy rates, especially in post-partum and low body condition score (BCS) cows.
For estrus synchronization
, a controlled internal drug release (CIDR) dispenser was inserted (D0; 0800 to 0900 h) for 14 days (D14; 0800 to 0900 h) and a single injection of 125 [micro]g prostaglandin F2[alpha] (PGF2[alpha]) (Estrumate; Intervet International B.V Boxmeer, The Netherlands) was administered intramuscularly 1 day before starting the pFSH treatment (D11).

It is concluded that CIDR-based estrus synchronization
protocol improves the reproductive efficiency of non-descript cows during the low and peak breeding seasons.
Therefore, the purpose of the current experiment was to conduct the qualitative and quantitative analysis of bacteria from vaginitis associated with the use of different intravaginal implants in ewes subjected to estrus synchronization
