摘　　要： 研究投喂不同剂量LHRH-A粗品对雌性金鲫GtH分泌和卵巢发育的作用。以LHRH-A粗品0.01 mg/g饲料和0.1 mg/g饲料的剂量投喂6周后,与对照组相比,金鲫血清的GtH水平显著升高;部分卵母细胞已发育至Ⅳ+++时相,GSI明显增长。这些结果表明将LHRH-A粗制品拌入饲料长期投喂金鲫后,能使血清GtH水平明显提高,进而促进性腺的发育成熟。 Effects of oral administration of different doses of coarse LHRtt-A on GtH secretion and ovarian development are investigated in Carassius auratus red variety. After 6 weeks of feeding with coarse LHRH-A 0. 01mg/g. diet or LHRH-A 0. 1 mg/g. diet, the serum GtH levels in female Carassius auratus increase significantly compared with the control, gonadosomatic index （GSI） increase apparently, and some oocytes in the treated groups （LHRHA 0. 01mg/g. diet or LHRH-A 0.1mg/g, diet） are highly developed to late phase 4 while that in the control keep still in phase 3. These results indicate that long-term dietary administration of coarse LHRH-A can increase GtH levels in serum, and subsequently resulte in gonadal deveopment and maturation in Carassius auratus.
