“…Souza et al (2011) observed the end of estrus in goats at 70.9 h after sponge removal treatment for 10 days using 60 mg MAP, 100 IU eCG every 10 kg of weight, and 37.5 μg PGF2α, with slightly longer duration compared to the average of 59.80 h in the groups. Owing to the higher range for the onset of estrus (45 h), these authors obtained an estrus duration (ED) of 25.5 h, similar to that found in this experiment (24.71 h).…”

“…In goats estrus can start in the range of 12 -48 hours after withdrawal of the progesterone source (TRALDI et al, 2007). In addition, based on the results of other studies, the range for estrus onset averages 40.65 ± 3.27 h (250 IU eCG), 32.54 ± 3.00 h (500 IU of eCG) (NAVA-TRUJILLO et al, 2010), and 31.53 ± 2.81 h (250 IU eCG) (MAIA JÚNIOR et al, 2009).…”

The objective was to evaluate the efficacy of hormonal subdoses at acupoint Hou Hai in estrus synchronization of goats. Sixty-nine females goats received intravaginal sponges containing 60 mg of medroxyprogesterone acetate for seven days and were randomly distributed among three treatments: T1 (n = 23): application of 125 μg of PGF2α on the sixth day (D6) and 300 UI of eCG on the seventh day (D7), both intramuscularly (IM); T2 (n = 23) and T3 (n = 23): application 37.5 μg of PGF2α at D6 and 90 UI of eCG at D7, applied by Hou Hai acupuncture and false acupuncture (IM), respectively. The goats were subjected to hormonal protocol and monitored for the coverage and evaluation of reproductive parameters. The data were subjected to normality analysis, followed by appropriate statistical tests for each variable. Greater numbers of estrus goats were obtained in treatments one (T1 = 100%) and three (T3 = 91.3%) (p < 0.05). No difference was observed (p > 0.05) for sponge removal intervals at the beginning (35.9 h) and end (59.8 h) of estrus, and for the duration of estrus (24.7 h), gestation rate at 30 (77%) and 60 (76.7%) days, and prolificacy (1.9). The use of PGF2α and eCG in subdoses applied to the Hou Hai acupoint or false acupoint was efficient in synchronizing estrus in goats, based on the rate of gestation and prolificity of the animals.

Sessenta e nove fêmeas receberam esponjas intravaginais com 60mg de acetato de medroxiprogesterona por sete dias, e distribuídas aleatoriamente em três tratamentos: T1 (n = 23): aplicação de 125 µg de PGF2 α no sexto dia (D6) e 300UI de eCG no sétimo dia (D7), ambos por via intramuscular (IM); T2 (n=23) e T3 (n=23): receberam 37,5 µg de PGF2 α no D6 e 90UI de eCG no D7, aplicados no acuponto Hou Hai e em falso acuponto (IM), respectivamente. As cabras foram submetidas ao protocolo hormonal e monitoradas para realização das coberturas e avaliação de parâmetros reprodutivos. Os dados foram submetidos à análise de normalidade, seguido dos testes estatísticos adequados para cada variável. Obteve-se maior número de cabras em estro nos tratamentos um (T1=100%) e três (T3=91,3%) (p < 0,05). Não houve diferença (p > 0,05) para os intervalos da retirada da esponja ao início (35,9h) e final (59,8h) do estro, bem como para a duração do estro (24,7h), taxa de gestação aos 30 (77%) e 60 (76,7%) dias, e prolificidade (1,9). O uso de subdoses de PGF 2 α e de eCG aplicados no acuponto Hou Hai ou em falso acuponto foram eficientes na sincronização de estro em caprinos, com base na taxa de gestação e prolificidade dos animais.

The objective of this study was to evaluate the efficacy of delivering reduced doses of hormones via the Bai Hui acupoint in estrus synchronization in goats. A total of 40 goats received intravaginal sponges with medroxyprogesterone acetate for 7 days. The goats were then randomly distributed into 5 treatment: T1 - application of 132.5 ?g of cloprostenol and 300 IU of equine chorionic gonadotropin (eCG), both by intramuscular injection (IM); T2 - application of 39.75 ?g cloprostenol at the Bai Hui acupoint, and 300 IU of eCG by IM; T3 - application of 132.5 ?g of cloprostenol by IM, and 90 IU of eCG at the Bai Hui acupoint; T4 - application of 39.75?g of cloprostenol and 90 UI of eCG, both in Bai Hui and T5 acupuncture: application of 39.75?g of cloprostenol and 90 UI of eCG, both applied in false acupoint. The goats were subjected to an estrus synchronization protocol and monitored for estrus detection, coverage and evaluation of reproductive parameters to detect entry into estrus. The data were subjected to normality tests, followed by appropriate statistical analyses of each variable. There was no significant difference (P > 0.05) in the percentage of animals in estrus (95.00 ± 11.18%), interval between sponge removal and beginning of estrus (49.72 ± 8.93 h), interval between sponge removal and end of estrus (76.84 ± 11.98 h), duration of estrus (27.08 ± 8.68 h), size of the largest follicle (6.82 ± 0.44 mm), interval between sponge removal and ovulation (78.28 ± 10.82 h), time from ovarian onset to estrus (28.52 ± 5.44 h), follicular growth rate (0.86 ± 0.29 mm/day), number of ovulations (1.32 ± 0.23), plasma progesterone concentration at 7 days after ovulation (10.28 ± 1.65 ng.mL-1), and gestation rate at 30 days after the beginning of estrus (75 ± 12.5%). However, the cost of the synchronization protocol per animal was 43.42% lower in treatments 4 and 5 (30% of the doses) than in treatment 1 (100% of the dose). Ovulation and estrus were efficiently synchronized with the use of 39.75 ?g of sodium cloprostenol and 90 UI of eCG, applied at the Bai Hui acupoint or at a false acupoint.
