1 Update on Southwest Center Dairy Research MU Pasture-based Dairy Team

2 Traditional vs. Accelerated Milk Replacers Stacey A. Hamilton Ph.D. and Scott Poock DVM University of Missouri Project sponsored by Hartville Feed and Milk Specialties Global Animal Nutrition

3 Objectives Determine if intensified milk feeding in small framed dairy heifers will result in: Younger weaned calves at similar weights as traditionally fed calves Decreased breeding and calving age Increase milk production in first lactation

4 Parameters 16 Holstein, Jersey or Crossbred heifers assigned to Milk Formula 1 as the traditional milk replacer program 21 Holstein, Jersey or Crossbred heifers assigned to Velocity as the accelerated feeding program Calves were assigned as groups of 8 and mob-fed using 10 nipple feeders Birth weight: MF1 = 70.6 # Velocity = 69.0 # Average age of start of treatment MF1 = 9.7 days Velocity = 7.0 days

28 Residual Feed Intake and Pasture Intake Trial Heifers in Gro-Safe feed out systems Measures actual dry matter intake Measures weight gain Heifers measured for actual intake as milking cows 2-3 lactations Use of titanium dioxide and alkanes as markers April, June, August, October Look for genetic markers in future Better understanding of pasture intake

32 Summary of Preliminary Data Too soon to make any judgments Pasture intake around 2.2% of body weight Substitution rate of grain impacting? Ballpark number for stocking rate Ballpark number for allocation Genetic marker search with more data and diversification Appears some relationship between RFI and milk to feed ratio

33 Use of Grazing Model Remember this is only a tool Allows What if? scenarios Forage combinations Stocking rates Grain feeding Junk in.junk out! Be honest If it looks to good to be true.well it probably is!
