Use of olive extract in the preparation of a feed additive for improving the reproductive performance of mammals
By adding olive extract to the diets of pregnant and lactating animals, the lack of specific dietary intervention in existing technologies was addressed, significantly improving embryo survival rate, live birth rate, and maternal lactation capacity, thus enhancing maternal and infant health.

AI Technical Summary
Current nutritional regulation methods lack specific dietary intervention strategies for metabolic abnormalities during pregnancy and lactation, which affects maternal and embryonic health. In particular, during pregnancy and lactation, maternal obesity or overnutrition can lead to a high risk of complications, affecting fetal development and maternal lactation capacity.
Olive extract was added to the diets of pregnant and lactating animals. The specific preparation process included crushing the edible part of olives, mixing with ethanol solution, water bath extraction, rotary evaporation concentration, and chromatography purification to obtain olive extract. The amount added was 0.05 wt% to improve reproductive performance.
It significantly improved the embryo survival rate, number of live offspring, litter weight at birth, and maternal lactation capacity in mammals, providing nutritional regulation effects during pregnancy and lactation.
