摘　　要：为研究"吉姆瑞1号"对发情异常后备母猪繁殖功能障碍的防治作用,选择达到7.5月龄、体重约115 kg且体况相近的不发情或发情异常的后备大白母猪40头,随机分成2组,每组5栏,每栏4头,对照组饲喂基础饲粮,吉姆瑞1号组在基础饲粮中每天每头添加一剂"吉姆瑞1号",连续拌料饲喂1周,两组试验猪的配种方式以及后续饲养管理方法一致,跟踪测定两组后备母猪的配种性能以及后续初产母猪的繁殖性能。研究结果表明,1)后备母猪发情配种性能方面:吉姆瑞1号组在7 d内和14 d内发情率分别比对照组高11.60和28.33个百分点,返情率比对照组低16.67个百分点,受胎率比对照组高21.60个百分点(P<0.05)。2)后续初产母猪繁殖性能方面:吉姆瑞1号组与对照组相比,在产仔数、产活仔数、产弱仔数、初生窝重、21日龄断乳窝重和成活率、28日龄转群窝重和成活率等繁殖性能均无显著差异(P>0.05)。结果提示,发情异常的后备母猪配种前连续1周饲喂添加"吉姆瑞1号"的饲粮(后续未作添加),对于促进异常后备母猪的发情及配种受胎方面具有良好的预防和治疗效果;对于后续初产母猪繁殖性能方面的进一步提升,需要针对母猪妊娠与泌乳阶段的生理特点,持续加强饲养管理和生殖保健。The experiment was conducted to research the effects of Jimurui 1 feed supplementation on the reproductive performance of abnormal oestrus gilts. 40 abnormal oestrus gilts （about 7.5 months and 115 kg） were randomly divided into 2 groups equally. Each group was divided into 5 columns equally. The control group was fed the basal diet and the test group was added a dose of“Jimurui 1”per gilt per day on the basis of diet during the first week. Taking the same treatment to the both groups in the breeding methods and following management. Tracking to measure the reproductive performance of the two groups.The results showed as follows： 1） The gilts oestrus performance：the group of＆quot;Jimurui 1was higher 11.60 and 28.33 percent points than the control group in 7 d and 14 d oestrus rate and lower 16.67 percent points in the oestrus returning rate, the control group conception rate was higher 21.60 points than that of the control group （P〈0.05）. 2） The subsequent reproductive performance in gilts：Compared with the control group, the group of Jimurui 1; was no significant difference in total number born, number born alive, birth litter weight, 21-day and 28-day litter weight and survival rate （P〉0.05）.It proved that Jimurui 1have great effects to improve oestrus, mating and conception rate of the gilts. To improve the subsequent reproductive performance of the gilts, more management should be taken according the characteristic of the gilts in pregnancy and lactation.
