Sugar (dextrose) increases the insulin content of every animal. High insulin content has a positive effect on heat detection of sows. However, post-ovulating, insulin plays no major role in prevention of sows needing to be re-served. Lianol on the other hand, has a wider impact by increasing the growth factor content IGF-1.
Prior to ovulation; Lianol causes:
Stimulation of the ovaries
Improvement of quality of ovulating egg-cells (FSH/LH sensitivity is increased)
Improvement of heat detection
Post-ovulating; it is the growth factor IGF-1 that causes the egg-cells to attach to the uterine wall and the placenta to develop. Therefore, Lianol has an influence on both heat detection and sows needing to be re-served. Due to being complementary to insulin, Lianol enhances the effect of dextrose.
