Abstract

Veterinaria Mexico OA ISSN: 2448-6760 Cite this as: Aguilar U, Hernandez Ceron J, Dominguez Y, Gutierrez C. Ovulation rate, prolificacy and pregnancy rate in goats treated with oral glycerol. Veterinaria Mexico OA. 2016;3(1). doi: 10.21753/vmoa.3.1.360 This study tested whether the oral administration of glycerol at the time of progestin removal and in the first 6 days of the estrous cycle increased the ovulation rate, prolificacy, and pregnancy rate in goats. Intravaginal sponges impregnated with fluorogestone acetate were inserted into 129 goats for 12 days; upon sponge removal, goats were randomly assigned to one of the two following treatment groups: the glycerol group (n = 65), which received an oral drench of 100 mL of glycerol upon sponge removal and was repeated on days 0, 2, 4, and 6 following estrus (estrus = day 0), and the control group (n = 64), which did not receive glycerol. The goats in estrus were mated, and their ovulation rate was determined by ultrasonography between days 8 and 12 of the estrous cycle. Pregnancy was diagnosed by ultrasonography on day 40, and the prolificacy was determined at birth. In 6 goats treated with glycerol and 5 controls, their insulin concentrations at 0, 2, 4, 8, and 12 h after the glycerol drench were determined by radioimmunoassay. The proportion of goats with multiple ovulations (glycerol = 71 vs control = 64) and the proportion of goats with multiple births (glycerol = 52 vs control = 56) were similar (P > 0.05) between treatments. Likewise, the pregnancy rate was similar (P > 0.05) between treatments (glycerol = 88 vs control = 85%). The insulin concentrations tended to be higher in goats treated with glycerol (P = 0.08). In conclusion, an oral drench of 100 mL of glycerol at the time of progestin withdrawal and in the first 6 days of the estrous cycle did not increase the ovulation rate, prolificacy, or pregnancy rate in goats.

口服甘油处理山羊的排卵率、繁殖率和妊娠率
引用本文:Aguilar U, Hernandez Ceron J, Dominguez Y, Gutierrez C.口服甘油治疗山羊的排卵率、繁殖率和妊娠率。墨西哥兽医局。2016; 3(1)。本研究测试了在去除黄体酮时和发情周期的前6天口服甘油是否能提高山羊的排卵率、繁殖力和怀孕率。将经醋酸氟石浸渍的阴道内海绵植入129只山羊体内12 d;去除海绵后,将山羊随机分为以下两组:甘油组(n = 65),在去除海绵后口服100 mL甘油,并在发情后(发情=第0天)第0、2、4和6天重复,对照组(n = 64)不服用甘油。将处于发情期的山羊进行交配,在发情周期的第8 ~ 12天用超声检查测定其排卵率。第40天超声诊断妊娠,出生时测定生育能力。用放射免疫法测定6只山羊和5只对照山羊在甘油浸泡后0、2、4、8和12 h的胰岛素浓度。两组山羊多次排卵的比例(甘油= 71,对照组= 64)和多次分娩的比例(甘油= 52,对照组= 56)相似(P < 0.05)。同样,两组的妊娠率相似(P < 0.05)(甘油= 88 vs对照组= 85%)。甘油处理的山羊胰岛素浓度有升高趋势(P = 0.08)。综上所述,在停药时和发情周期的前6天口服100ml甘油不会增加山羊的排卵率、繁殖力或怀孕率。图1所示。治疗的概要概述。
