Production research and measurements are tedious and fascinating. Research often allows producers to fine-tune their animal management processes to optimize production and animal welfare. With a little help from veterinarians and animal health pros, dairy producers will appreciate learning about the research shared here. Two takeaways stand out.
- Heifers around 20-21 months of age at first calving versus 24 months of age have been found to produce about 1,000 lb. less milk in the first lactation. This may also carry over into subsequent lactations.
- Calving difficulty needs to be recorded and managed to be minimized to avoid negative effects on the dam and calf.
