A calf’s immune system is naïve at birth; she requires high-quality colostrum within the first few hours of life to achieve successful passive transfer of immunity through absorption of IgG across the intestinal wall and into circulation.

LAND O LAKES® Bovine IgG Colostrum Replacer is specially formulated to replace or supplement maternal colostrum as an aid in the treatment of failure of passive transfer. LAND O LAKES® Colostrum Replacer provides a newborn calf with important antibodies, including immunoglobulin G (IgG), to help develop her immune system.

LAND O LAKES® Amplifier® Max, an original formulation, delivers a performance level of nutrition featuring an exclusive blend of fat sources that is more efficiently used by the calf to support immune function. LAND O LAKES® Amplifier® Max is now enhanced with exclusive active microbials. These active microbials, along with the existing feed technologies, help support a calf’s gut microbiome.

Land O Lakes Amplifier Max Protein Blend is a blend of highly digestible proteins that complement each other. This product is enhanced with the exclusive active microbial that helps support the calf gut microbiome. These active microbials, along with the existing feed technologies, help support a calf’s gut microbiome.

For optimal results, feed in combination with AMPLI-Calf 20 Starter Feed through 12 weeks and transition to AMPLI-Calf Grower Feed at 12-13 weeks-24 weeks of age.
