Current measures for the improvement of the reproductive performance of sows in the German Democratic Republic by means of insemination at standing oestrus



Current measures for the improvement of the reproductive performance of sows in the German Democratic Republic by means of insemination at standing oestrus



Tierzucht 41(7): 313-316



An account is given of methods used for the synchronization or induction of oestrus in sows and gilts in the German Democratic Republic. In 1986, 42.5% of sows and gilts were synchronized or induced prior to insemination soon after standing oestrus, followed by a 2nd insemination 8 h later.
