Abstract The effect of single subcutaneous melatonin (MEL) administration on reproductive performance in Singharey goats during the non-breeding season was studied. Forty clinically healthy female goats were selected and divided into four groups (control, MEL - 10, MEL - 20 and MEL - 40) of 10 animals each. Treatments were given as single subcutaneous injection of melatonin dissolved in one ml sterilized corn oil in different groups as MEL - 10 (10 mg/animal), MEL - 20 (20 mg/animal) and MEL - 40 (40 mg/animal). Control group was injected with placebo (one ml sterilized corn oil per animal). Oestrus induction response was 20 %, 80 %, 100 % and 30 % in control, MEL - 10, MEL - 20 and MEL - 40, respectively. Time interval to oestrus following melatonin treatment was minimum in MEL - 10 (11.25 ± 0.12 days) and maximum in control group (16 ± 5.00 days). Kidding rate was significantly (P 0.05). Serum MEL concentrations in the treated groups of goats increased significantly and the peak concentration was recorded on day 12 post treatments and thereafter it decreased sharply to reach the basal level on day 40 post treatment. The serum progesterone concentration was significantly (P

在印度东北部亚热带条件下,单一褪黑激素处理提高了辛格瑞山羊在非繁殖季节的繁殖性能

摘要 研究了单次皮下注射褪黑激素 (MEL) 对非繁殖季节 Singharey 山羊繁殖性能的影响。选择四十只临床健康的雌性山羊并分成四组(对照、MEL-10、MEL-20和MEL-40),每组10只动物。治疗以单次皮下注射溶解在 1 ml 灭菌玉米油中的褪黑激素的形式进行,分为 MEL - 10(10 毫克/动物)、MEL - 20(20 毫克/动物)和 MEL - 40(40 毫克/动物)。对照组注射安慰剂(每只动物一毫升消毒玉米油)。在对照、MEL-10、MEL-20和MEL-40中,发情诱导反应分别为20%、80%、100%和30%。褪黑激素治疗后到发情的时间间隔在 MEL - 10 中最短(11.25 ± 0.12 天),在对照组中最长(16 ± 5。00 天)。开玩笑率显着(P<0.05)。治疗组山羊的血清 MEL 浓度显着增加,峰值浓度在治疗后第 12 天记录,此后急剧下降,在治疗后第 40 天达到基础水平。血清孕酮浓度显着(P
