摘要

本研究旨在调查短期谷氨酸供应对低体况评分山羊卵巢反应的影响。21 只山羊每隔 7 天注射 3 次前列腺素类似物,使其发情和卵泡波同步。山羊被分配到单剂量(LBCG1 组,n = 7)或间隔五天分两次(LBCG2 组,n = 7)注射 10 mg/kg LW (iv) 谷氨酸的组中。对照组(LBC;n = 7)接受生理盐水。谷氨酸钠处理不会影响葡萄糖、胆固醇或谷胱甘肽过氧化物酶水平、体重或脂肪沉积。在实验期间,LBCG2 组的卵泡数量增加(P < 0.05),卵泡直径增大(P < 0.05)。谷氨酸的供应改善了LBCG组卵巢内多普勒血流面积的大小(P < 0.05),LBCG2组的第二剂量也诱导了卵巢动脉收缩和舒张峰值的升高(P < 0.05)。诱导排卵后,LBCG2 表现出较高的(P < 0.05)黄体体积和血管面积。我们得出的结论是,在低体况山羊中,相隔五天注射两次谷氨酸盐能有效刺激其卵巢。

Effect of one or two fixed glutamate doses on follicular development, ovarian-intraovarian blood flow, ovulatory rate, and corpus luteum quality in goats with a low body condition score.

This study aimed to investigate the effect of a short glutamate supply on the ovarian response in goats with low body condition scores. Twenty-one goats had their estrus and follicular waves synchronized using three injections of prostaglandin analog at seven-day intervals. Goats were allocated to groups receiving 10 mg/kg LW (iv) of glutamate administered in a single dose (group LBCG1, n = 7) or in two doses five days apart (group LBCG2, n = 7). The control group (LBC; n = 7) received saline solution. Glutamate treatment did not affect glucose, cholesterol, or glutathione peroxidase levels, body weight, or adipose deposits. During the experimental period, the LBCG2 group showed a higher (P < 0.05) number of follicles (> 3 mm) and an increase in follicle diameter (P < 0.05). Glutamate supply improved (P < 0.05) the intraovarian Doppler blood area size in the LBCG groups, and the second dose in LBCG2 also induced a higher (P < 0.05) systolic and diastolic peak of the ovary artery. After ovulation induction, LBCG2 exhibited a high (P < 0.05) volume of the corpus luteum and vascularized area. We concluded that the supply of two doses of glutamate five days apart was efficient in ovarian stimulation in goats with a low body condition.
