摘要
本试验选用１８头经产二花脸母猪，根据胎次和以往生产性能分成对照组和试验组，每组为９头。试验组母猪从分娩的第１天起在日粮中添加５．０ｍｇ／ｋｇＩＦＶ－Ｄ，至４５日断奶时结束。结果表明：（１）．ＩＦＶ－Ｄ影响母猪泌乳量。母猪第５天的每次泌乳量，试验组为２７１．７４±１９．８０ｇ极显著地高于对照组２２５．６１±１６．２７ｇ，而第２０天的每次泌乳量，对照组为３５３．１４±１９．８７ｇ显著地高于试验组３０５．７２±１５．７３ｇ。（２）．ＩＦＶ－Ｄ对仔猪生长的影响表现出前期（前１０天）试验组高于对照组，而后期对照组快于试验组。（３）．试验组９头母猪中，在哺乳期第２８～３５天期间有５头出现发情行为。
multiparious Erhualian sows is divided into treated group & control group by their parity and previouly productivity,each group being 9 sows.The treated group feed 5.0 mg/kg IFV-D in the diet from the day parturition to postartum 45 days. The results are:(1).IFV-D has influenced on sows milk yield. On 5th lactating day,timely milk yield of treated group is very significantly higher than that of control, P<0.01,which is 271.74±19.90 g versus 225.61±16.27 g. However,on the 20th day,timely milk yield of control is very significantly higher than that of treated group(P<0.01),that is 353.14±19.87 g versus 305.72±15.73 g.(2).At the earlier lactating period (1￣10d),the piglets weight gain of treated group is bigger than that of control.However at the later period
