Abstract: Grazing systems are always described as a strategic approach to diminishthe total heifer cost of dairy farms compared to confinement systems. Apart from the evident cost reduction, long-term effects on lactation performance, mainly on milk yield and dry matter intake, seem to be positively associated with raising heifers on pasture. However, few studies have studied these impacts extensively in dairy cattle. So, a current trial has been initiated to elucidate the potential metabolic, physiological, and behavioral adaptations associated with the heifer-raising system on future lactation performance of dairy cows. Thus, the current study aims to provide potential explanations for this observed phenomenon.
