The present study demonstrated that the
gilts first inseminated with BF of 17 mm or more
had a higher TB on farrowing than those first
inseminated with BF of 14.0-16.5 mm. In practice,
the gilt rearers ought to concentrate on gilt
management in terms of nutritional and feed
provision, estrous detection, insemination time and
objective methods for evaluating body condition,
such as BF measurement, in order to prepare high
quality sows for subsequent parities.
