With lots of farmers around the country focusing on Autumn calving, it’s a good time to have a listen to Dairy Australia’s Ruairi McDonnell speaking with Dr Bob James, a dairy consultant from the US who's had a long and productive career in extension, teaching and research, specialising in dairy calf management and rearing.
In a thought provoking discussion, Bob spoke about several aspects of calf rearing, including:
- How much milk should you feed your calves each day
- Target weight gains pre-weaning
- Long term effects of how heifer calves are reared on their milk yield as mature cows
- Pros and cons of automatic calf feeders
- Antibiotic use in calves
- Role of “secondary” or transition colostrum in calf performance
