Many farms run into the shortage of colostrum due to seasonal calving, diseases and general poor quality of generic products.

The Miner Institute Farm Report recently detailed a preliminary summary of 13 studies discussing colostrum management that directly affects calf health by the transfer of immunity (PTI). The serum IgG > 10 g/L at 24 hours of birth is most commonly used industry-wide for developing adequate PTI.

These colostrum replacers can be based on IgG sources as plasma-derived or colostrums-derived.

One of the biggest concerns of using the colostrum replacer products can be the total amount fed and how the efficient the lgG is absorbed into the animal. Ideally, 30 to 40 percent of AEA is a satisfactory level for most colostrum replacer products from either source.

In fact, feeding CDCR at a suggested dose at > 150 g lgG is more than likely to guarantee the successful rate PTI for your calves. However, be extremely cautious if you use PDCR at a similar dose to due to greater variations of performance in the animal.
