Maximise Production with Smart Calf Rearing: ShaunBalemi sits down with lactation physiologist Dr Adam Geiger to break down the calf rearing decisions that drive future milk production, first lactation performance and lifetime cow productivity.
They cover colostrum management for passive transfer, how to reduce bacterial contamination in calf feeding gear, and why the first 60–90 days are important for mammary gland development and genetic potential.
You’ll also hear practical guidance on milk feeding rates(including higher volumes), a slower weaning plan (7–14 days), calf starter and calf meal formulation (starch, protein, fibre targets), and why water quality testing can make or break solid feed intake. Dr Geiger explains trace mineral reducing gaps when feeding whole milk, with a focus on manganese, zinc, copper and iodine, plus vitamins like D and E, and how iron in water can interfere with mineral availability.
Key takeaways:
Colostrum management is crucial for calf health and future milk production.
The first 60 to 90 days of a calf's life are critical for udder development.
Higher feeding rates of milk lead to better growth and health in calves.
Water quality significantly impacts calf health and feed intake.
Manganese is essential for hormone production and mammary growth.
Calf meal formulation should balance starch, protein, and fibre for optimal growth.
Testing water quality can reveal issues that affect calf nutrition.
Whole milk lacks essential trace minerals and vitamins needed for calf growth.
Establishing a routine in feeding helps calves adapt better to solid feed.
Investing in calf nutrition can lead to better lifetime productivity in dairy cows.
