“…The results shows that emphasis should be laid on days two to five for oestrus detection when PGF 2α is used for oestrus synchronisation in RSG and this is the focus and novelty of this work. Similar tightness was also observed with the P 4 P and agrees with earlier reports in RSG (Bello, 2011;Omontese et al, 2012;Omontese et al, 2013). For practical application, emphasis should be laid on days one to three for oestrus detection when P 4 P is used for oestrus synchronisation in RSG.…”

Comparative oestrus synchronisation was carried out in 52 Red Sokoto does with the aim of evaluating the effectiveness and tightness of synchrony of prostaglandin F 2alpha (PGF 2α) and progesterone pessaries for clinical application. Does were randomly divided into PGF 2α treated (n = 18), progesterone pessaries treated (n = 18) and control (n = 16) groups. A double injection protocol of PGF 2α, 12-days apart, and progesterone pessaries inserted for 12-days were used to synchronise oestrus, with no treatment to the Control group. Six sexually active bucks were used as heat detectors. Intensive and non-intensive oestrus detections were employed using visual observation and apronisation. Standing to be mounted was used as the main sign of oestrus. Oestrus response rate was 88.9 %, 33.3 % and 37.5 % for PGF 2α, progesterone pessaries and Control groups respectively. Tightness of oestrus synchrony for PGF 2α was within four days, while that of progesterone pessaries was within three days. Progesterone pessaries retention rate was 94.4 %. It was concluded that PGF 2α double injection, 12-days apart, synchronised oestrus in Red Sokoto doe was more effective with a tighter synchrony and recommended for clinical use than progesterone pessaries inserted for 12-days.

“…In response to the stimulatory activity of PMSG following CIDR withdrawal, longer durations of estrus observed in the treated ewes and does; 36-48 and 48-72 h, respectively which supports the findings of Omontese et al, (2012). In our study, the high pregnancy rates coincide with Amer and Hazzaa (2009).…”

Key words:CIDR, CRL, BPD, FOD, Progesterone, PMSG, Ultrasound.The present study aims to evaluate the impact of controlled internal drug release (CIDR) in combination with prostaglandin F2α (PGF2α) and pregnant mare serum gonadotropin (PMSG) treatments on reproductive performance of dairy ewes and does besides, evaluation the accuracy of pregnancy diagnosis during the breeding season. Twenty female animals divided as Ossimi ewes (n=10) and Baladi does (n=10) were subjected to ovsynch regimen. Ultrasonographic examinations were conducted weekly using realtime B-mode ultrasound scanner by transrectal linear and transabdominal convex probes starting from day 14 post service. This study showed that estrus response was 100% in both ewes and does. The conception rates were 90% in ewes and 80 % in does. The incidence of twining was higher in ewes when compared to that in does with incidence rate 67% and 50 in ewes and does, respectively. The accuracy of ultrasound examination for determining fetal number was 100% for single and twin pregnancy. The birth rate was 100 % for both species; and this was confirmed at lambing / kidding. In conclusion, our results indicate that using biotechnologies such as ovsynch regimen and pregnancy diagnosis by ultrasonography are useful to improve the management of reproduction in ewes and does.

“…This result was in accordance a study by Omontese et al, (2012) that the 14 -day fluorogestone acetate sponge treatment alone could synchronize estrus in Sahel goats but the additional administration of eCG increases estrus response, shortens time to onset of estrus, lengthens the duration of estrus and tightens estrus synchrony. The onset of estrous from PGF 2α treatment of this research was longer than 69.03 hours, compared to a previous study that the interval of estrus after the second dose of PGF 2α was 48 h (Esteves et al, 2013).…”

The objective of the research was to determine the estrous profile of Etawah Crossbred goats after estrous synchronization with different methods. Eighteen does aged 12-24 month old were divided in three groups to receive estrous synchronization treatments (T1 = 14 days intravaginal implant of 60 mg of progesterone (MPA), T2 = two times injection of 5 mg PGF2α (lutalyse) in 11 days interval, and T3 = 10 days of intravaginal implant of 60 mg of progesterone (MPA) + injection of 5 mg PGF2α 48 hours before removal) with six replications. The parameters consisted of estrous behaviour, changes in size and colour of vulva, and duration of estrus when the number of superficial and keratin cells were dominating in the vaginal mucus cell. Data from estrous behaviour and score of vulvar colour was analyzed using Kurkal Wallis test, while onset of estrus, size of vulva slit and estrous duration was analyzed using ANOVA and Duncan test. The result showed that estrous behaviour and changes in color and size of vulva were not significantly different, but estrous duration was significantly different. Estrous duration in T1 (31.30 hour) and T2 (31.10 hour) was significantly longer than that of T3 (11.36 hour). It is concluded that different methods of estrus synchronization affected estrous quality equally but it affected the estrous duration differently based on vaginal mucus cells. Treatment implant vaginal sponge content progesterone for 14 days and double injection of PGF2α with 11-day interval given longest estrous duration.
