Research conducted at South Dakota State University provides some insight on the importance of post breeding management, especially following AI, explained George Perry, SDSU Extension Beef Reproductive Management Specialist & SDSU Professor.
"Previous research indicated that moving drylot-developed heifers to spring forage immediately after AI adversely affected average daily gain (ADG) and AI conception rates," Perry said.
However, he added that the research showed that after 27 days of grazing, there was no difference in ADG between heifers developed in a drylot and heifers developed on forage.
Perry referenced two studies conducted at SDSU to determine the impact of adaptation to grazing on weight change and activity when heifers were moved to spring forage (Experiment 1), and whether supplementing heifers when moved to pasture following AI improved pregnancy success (Experiment 2).
"Heifers that were grazing spring forage took more steps per day compared to heifers in the drylot," Perry said.
