de Feu et al. (
2009
). The levels of IGF-I observed in group T were instead
significantly higher during both the last part of the dry period and the first
14 weeks of lactation, displaying an improved energy balance as compared to the
traditional dry period group.
Whole-milk production underwent a reduction of 4%, much lower than the 19%
reported by de Feu et al. (
2009
), during the first 12 weeks of lactation. However,
milk quality in terms of fat and protein content was not affected by the length of the
dry period.
In conclusion, a reduction in the dry period resulted in a decrease in milk
production, but improved the periparturient endocrine status, with a positive impact
on both the metabolic balance and the time of postpartum resumption of ovarian
activity.
