Chapter One
Management Considerations from Parturition to the End of the Voluntary Waiting Period to Optimize Health and Reproductive PerformanceCarlos A. Risco
Abstract
From an animal health and well-being and performance perspective, the postpartum period is composed of an early window where health greatly impacts production and reproductive efficiency. Thus, appropriate management during this period is critical to ensure a normal state of cow health at the herd level to optimize production and reproductive performance. This chapter discusses management considerations from parturition to the end of the voluntary waiting period to optimize health and reproductive performance.
Introduction
Reproductive efficiency is vital for the economic viability of a dairy farm because it increases the likelihood of cows remaining in the herd, increases the number of cows that spend their productive life in profitable milk production, increases the number of calves born per year, and reduces involuntary culling (de Vries, 2006). However, reproductive efficiency has decreased in lactating dairy cows worldwide as evidenced by a reduction in conception rates (Macmillan et al., 1996; Royal et al., 2000; Lucy, 2001; de Vries, 2006). Although causes for this decline are multifactorial, attenuation of estrus expression in high-producing cows (Wiltbank et al., 2006), embryonic mortality (Santos et al., 2001), energy metabolism during early postpartum, and its interactions with immune function play a major role (Hammon et al., 2006). Further, the trend for larger herds coupled with labor shortage has resulted in new c
