摘　　要：为研究比较“吉姆瑞2号”与PG600激素对发情异常经产母猪繁殖障碍的防治效果，选择2～3胎次、体重、体况相近的断奶后不发情或屡配不孕的经产大白母猪60头，随机分成吉姆瑞2号组、PG600激素组，每组30头，对照组选择胎次、体重、体况相近的正常经产母猪30头，对照组饲喂基础饲粮，吉姆瑞2号组每天每头添加1剂“吉姆瑞2号”，连续拌料饲喂1周；PG600激素组于试验开始的第1天每头母猪注射1剂PG600，跟踪测定各组经产母猪的配种性能以及后续繁殖性能。研究结果表明，发情配种性能方面：吉姆瑞2号组在7 d内发情率比PG600组低53.34个百分点（P〈0.05），14 d内发情率、返情率以及总受胎率分别低20.00、8.21和10.00个百分点（P〉0.05），吉姆瑞2号组、PG600激素组母猪的受胎率均不如正常经产母猪对照组（P〈0.05）。后续繁殖性能方面：吉姆瑞2号组母猪窝均产活仔数、初生窝重、21日龄断奶和28日龄转群窝重及成活率均略高于PG600组，但3组母猪的后续各项繁殖性状均无显著差异（P〉0.05）。结果提示，“吉姆瑞2号”在刺激母猪发情方面不如PG600激素来的快速，但其对母猪的受胎率、产仔数以及仔猪21、28日龄窝重和成活率等后续繁殖性能的影响方面无显著差异，作用的效果持续而稳定。“吉姆瑞2号”的成分天然，对于倡导绿色养殖具有重要意义。The experiment was conducted to research the effects of ＂Jimurui 2＂ feed supplementation and PG600 hormone on the reproduction performance of abnormal oestrus sows. 60 abnormal oestrus sows（in 2~3 parity） were randomly divided into ＂Jimurui 2＂ and PG600 test groups equally. Another 30 normal estrus sows were se-lected to be the control group . The control group was fed the basal diet . The group 1 was added a dose of＂Jimurui 2＂ per sow per day on the basis of diet during the first week. The group 2 was injected a dose of PG600 per sow on the first day of the experiment. The reproductive performances of the three groups were tracked to measure. The results showed as follows： the sows oestrus performance： the group of ＂Jimurui 2＂ was lower 53.34 percent points than the PG600 group in 7 d oestrus rate（P〈0.05）, and lower 20.00, 8.21, 10.00 percent points in 14 d oestrus rate, the oestrus returning rate and the conception rate（P〉0.05）. The conception rate of both test groups were lower than that of the control group（P〈0.05）. The subsequent reproductive performance in sows：compared with the group of PG600, the group of ＂Jimurui 2＂ was rather better in number born alive, birth litter weight, 21-day and 28-day litter weight and survival rate, but no significant difference in every subsequent re-productive performance among the three groups（P〉0.05）. The results proved that＂Jimurui 2＂was not as quickly as PG600 in stimulating sow oestrus, but which had the same effects on the subsequent reproductive performance in sows. Moreover, ＂Jimurui 2＂ would be valuable in facilitating animal green production, as its main ingredients were natural.
