Failure of Passive Transfer Reduces •Calves with FPT: Long Term Performance - Delayed time to first calving (Can Vet J., 1986, 50:314) – Decreased average daily gain to 180 days (J. Dairy Sci., 1988, 71:1283) – Decreased milk and fat production at first lactation (J. Dairy Sci., 1989, 72:552) – for each unit of serum IgG > 12 mg/ml there was a 18 lb increase in ME milk
Calf Program Goals: 1. Double birth weight by 56 days 90 lb birth weight 180 lb @56 days 2. Calf mortality less than 5% 3. Calf morbidity (treatments) less than 10% Why do this •Achieve breeding weight at an earlier age •Potentially reduce AFC/increase BW@calving •Increase potential for Internal Herd Growth •Potentially increase milk yield •Potentially increase herd life
