It has been widely known that maternalnutrition may play a role in the development ofthe fetus in mammalians. Many studies havebeen conducted on the study of fetal programingin sheep and beef cows, but there is not muchresearch on the area in dairy cows. In 2013 atthe Tristate Dairy Conference, Dr. Schoonmakerpresented a review on the same topic showinga lot of possible areas of research for fetalprograming in dairy cows. Our idea is not tocover again his perspectives but to show someresults and future research on the area. On thisreview, we will show some data on the effectof increasing number of parity, days in milk,milk yield, and milk energy output at the timeof conception and their effect on the offspringperformance and longevity. At this time, thereis not much information on the role of differentnutrients impact on fetal programing. However,there are some physiological aspects of thefetal and placenta development that may beconsidered important for future research on theimpact of different nutrients during gestation.The current data on dairy cows suggest that cowhealth may be more important than milk yield ormilk energy output. The main reason of this maybe due to the possible, but unknown, increase inUHTXLUHPHQWVRQVXEDFXWHLQÀDPPDWRU\VWDWHVIn
