Nutrition for the pregnant dairy cow is of critical importance during the final three months of gestation, according to this article, as proper nutrient intake leads to better milk production and earlier return to estrus for the cow. More than three-quarters of fetal growth occurs during that period. Calves from properly nourished cows stand and ingest colostrum sooner and have better growth and body heat regulation compared with calves from improperly nourished cows.
