Expected Production Of A Holstein Cow (Part 2)
- As for second lactation, older animals usually produce 15 - 30 pounds over average daily milk production.
- Generally, mature cows and heifers will peak within 5 - 10 weeks after calving.
- After animals reach peak milk production, the average decline in milk per month is generally 10 - 15% for most of the lactation.
- If the herd has good nutrition, the decline may be slower.
- In late lactation, cows may experience 12 - 20% decline.
- A normal lactation length for cows is 290 to 310 days. Anything below 270 days is considered short.
