Rumen‐protected glucose hastens uterine involution and increases numbers of ovarian follicles in early post‐partum dairy cows

Rumen‐protected glucose hastens uterine involution and increases numbers of ovarian follicles in early post‐partum dairy cows

The primary objectives were to investigate the effects of feeding a new rumen‐protected glucose (RPG) on uterine involution and ovarian follicular dynamics in recently calved dairy cattle. From 4 to 30 days after calving, 16 Holsteins (first to third lactation, mean parity 1.75) were randomly assign...

Zusammenfassung:The primary objectives were to investigate the effects of feeding a new rumen‐protected glucose (RPG) on uterine involution and ovarian follicular dynamics in recently calved dairy cattle. From 4 to 30 days after calving, 16 Holsteins (first to third lactation, mean parity 1.75) were randomly assigned to be fed either a basal diet top‐dressed with either 600 g RPG (RPG group) or 600 g of the coating material and glucose (CONT group). Based on transrectal ultrasonography, conducted every 3 days starting 20 days after calving, the interval from calving to complete uterine involution was shorter in RPG versus CONT (27.1 vs. 30.4 days, p
