“…This proved that IVPS sponge alone coordinated the endocrine events and ovulatory estrus/conception in treated goats compared to an undisturbed control group and those exposed to buck or treated with sponge in combination with buck exposure or PG injection. These results, to some extent, concurred with reports of Kusina et al (2000), Kausar et al (2009), Parmar et al (2020) in different breeds of goats by adopting different synchronization protocols.…”

“…This technique offers tight synchrony and provides an acceptable level of fertility upon artificial or natural breeding. Synchronization of estrus in does and ewes, is achieved either by extending the luteal phase artificially with exogenous progesterone or potent progestagens and/or by reducing with prostaglandin F 2 α (PGF 2 α) or its analogs (Parmar et al, 2020. Intra-vaginal progestagen sponge impregnated with MAP and FGA is a common and traditional treatment of choice in small ruminants during the breeding and anestrus seasons and offers a convenient method to administer progestagens; perhaps a more simple method might be through oral dosing in feeds, e.g., Melengestrol acetate (MGA). Estrus response and fertility vary greatly when intra-vaginal sponges are applied, dependent on species, breed, co-treatment, management, and mating system.…”

“…No significant difference (p > 0.05) was observed in the litter size and fecundity among different groups. Earlier workers, however, reported variable litter size and fecundity such as1.22 ± 0.00 and 0.92 ± 0.01in local goats (Sunil Kumar et al,2018),1.30 ± 0.50 and 1.30 ± 0.50in Beetal x Dwarf goats (Kausar et al,2009),1.56 ± 0.12 and 1.12 in Criollo x Dairy breed of goats (Mellado et al,2000), 1.71 ± 0.18 and 1.00 ± 0.28 in Mashona goats (Kusina et al,2000), and1.36 and 1.34 in Surti goats (Parmar et al, 2020), respectively, for animals synchronized by buck effect, intra-vaginal progesterone sponges alone or in combination with either buck effect or PGF 2 α and other protocols.…”

This study was carried out to assess the influence of different estrus synchronization Protocols on fertility response in Surti does based on litter size, fecundity and twining rate. Thirty does were selected and divided into five equal groups (n=6 in each). Does of G1 group were treated with intra-vaginal progestagen sponges (IVPS) for 11 days. Does of G2 group received the same IVPS sponge for 11 days and exposure of sexually active apronized buck during the treatment period. Does of G3 group were treated as per G1 group along with i/m injection of PGF2andalpha; analog (125 µg, Cloprostenol) at the time of sponge removal. Does of G4 group were subjected to the buck effect and exposed to a sexually active patronized buck for 11 days, and does of G5 group was kept as a control without any treatment for 11 days. It was found that, none of the synchronization Protocols had significant effect on litter size, fecundity, and incidence of multiple kid birth and sex ratio in Surti does.

“…The does (n=15) received 12.5mg of PGF 2α , was administered (11 days apart) to the does, that does not exhibit behavioral symptoms of oestrus. In this study, estrous periods occurring within 1 to 7 days post-injection were classified as synchronized, although other investigators (Omontese et al, 2014(Omontese et al, , 2016Famakinde et al, 2017;Bello et al, 2019;Parmar et al, 2020) have reported oestrus to begin, after an average interval of ≤50 hrs.…”

In order to provide a more reliable, non-invasive method for defining the reproductive phase and determining the optimum time of ovulation, fifteen (15) apparently normal, non-pregnant cycling Red Sokoto does were used to evaluate exfoliative vaginal cytology sequential pattern; as well as temperature (rectal and vaginal) changes relative to various stages of the oestrus cycle. The does were synchronized by treatment with two luteolytic dosages of PGF 2α analogue (Lutalyse ® , Dinoprost tromethamine), 12.5mg administered intramuscularly in the gluteal region, 11 days apart. Vaginal smears were stained using a modified Papanicolaou method while the vaginal or rectal temperatures ( o C) was recorded with a standard (dry-bulb) clinical thermometer taken from 07:30 to 08:30 hrs daily and monitored throughout the period of experiment. In vaginal cytological smear examination, five exfoliated cell types were identifiable viz; anucleated superficial cells, superficial nucleated cells, intermediate cells, parabasal cells and leucocytes. Typically, the proestrus witnessed an increase in the proportion of anucleated superficial and superficial nucleated cells, with marked reduction in both intermediate and parabasal cells. Oestrous vaginal smear cells were highly cellular and consisted predominantly of superficial nucleated cells. Metestrus and Diestrus phases were markedly similar with respect to cell population and distribution. Metestrus phase showed drastic reduction in number of superficial cells and the proportion of leucocytes in smears began to rise while the desquamation of parabasal and intermediate cells with leucocytosis characterized the diestrus phase. In thermal study, there was significant (P< 0.05) difference in both mean rectal temperature (MRT) and mean vaginal temperature (MVT) values on day of estrus, the same not the case during the three other stages of the oestrous cycle, however, there was no significant (P> 0.05) difference between the mean rectal temperature (MRT) and mean vaginal temperature (MVT). Taken together, these results indicate that vaginal cytologic evaluation and temperature changes can be used as an adjunct tool during oestrus detection and for predicting time of ovulation in this breed; and furthermore, either of diurnal temperature rhythms, MRT or MVT can be used, in combination with other diagnostic tools, as a potential on-farm indicator of oestrous stage in Nigerian indigenous breeds of Red Sokoto does.

“…Induction and synchronization schemes in goats include hormones, particularly melatonin, gonadotropin / gonadotropin-releasing hormone (GnRH) or agonists, progestogens, and prostaglandins, alone or in combination, administered orally, by injection, or by intravaginal devices (Kusina et al, 2000;Whitley and Jackson, 2004;Arrebola et al, 2012Arrebola et al, , 2022Parmar et al, 2020;Zuñiga-Garcia et al, 2020;Anggraeni et al, 2021;Farooqi et al, 2021;Habeeb & Kutzler, 2021;Rivas-Muñoz et al, 2021;Skliarov et al, 2021;Khandoker, 2022;Hidayah et al, 2022;Wondim et al, 2022). And the essence of the hormonal stimulation for sexual heat induction is that the luteal phase of the sexual cycle is artificially simulated by the introduction of progesterone or other progestagen-based drugs in females.…”

One of the modern and widely used biotechnological methods for increasing the efficiency of animal reproduction is oestrus synchronization, which allows to reduce economic costs significantly. Using this method, a slight increase in the cost of processing animals is compensated by a significant decrease in labour costs, an increase in the technological efficiency of insemination and parturition, and the absence of costs for maintaining teasers. As a result, direct costs for reproduction might be reduced by a total of 50-60%. Induction and synchronization of sexual heat in goats have been used since the 1970s of the 20 th century, however, in our country, such a biotechnological method of regulating reproductive function is just beginning to be practised, but the results of such implementations are not available in the literary sources. Therefore, the goal of our research was to determine the effectiveness of oestrus induction and synchronization in goats under specific farm conditions in Ukraine. The experiments were conducted between April 2021 and February 2022 in «Agrosvit» dairy farm in Shestakove village, Chuguyiv district, Kharkiv region, on goats of Alpine and Zaanen breeds, aged 2-4 years, with a live weight of 35-55 kg. A total of 368 goats having ≤ 1 litre of milk production starting from the 180 th day of lactation, were involved in this trial. The synchronization protocol included the insertion of an intravaginal sponge with progestogen (day 0) (Chronogest CR polyester-polyurethane vaginal sponge, 20 mg of chronolone, intravaginally), injections of prostaglandin (Oestrophan, 0.2 ml, intramuscularly), and chorionic gonadotropin (Sergon, 500 OD, 1 ml, intramuscularly) (day 9), removal of the progesterone sponge (day 11), detection of heat (day 12) and insemination (day 13). Pregnancy diagnosis was determined by ultrasound examination on day 40 after artificial insemination. In our studies, using an oestrus induction and synchronization protocol based on progestogen sponge, prostaglandin and chorionic gonadotropin, 93.7% of treated goats were inseminated with a fertility rate of 158.9%. According to the results of the study, it can be concluded that oestrus induction and synchronization in goats is an effective biotechnological technique that allows increasing the efficiency of the use of genetic resources of high-value animals significantly, to increase the scale of their participation in the process of reproduction of livestock while maintaining a high level of physiological functions of the reproductive system. In particular, such studies will help to determine the most appropriate oestrus synchronization protocol and to better understand the effect on sexual behaviour and hormonal influence, and to inseminate goats at the most optimal time, in a short time, with a shortened period of kidding.
