How are lactation groups determined?
Lactation groups (libCalc.mBuckets.Buckets)
Number of bred cows < 51: All cows
Number of bred cows < 101: 1st, 2nd+ and All cows
Number of bred cows >=101: 1st, 2nd, 3rd+ and All cows.
How is HDE determined?
HDE is determined as follows:
If the postHDR Services 1-2 All Lactations is <> 0 then that is HDE
Else if postHDR Services Sum of 1 - 2, 2 - 3 and 3 - 4 All Lactations <> 0 then that is the HDE
—- Alternate HDE used for estimating pregnancies Else
—- Use only reported pregnancies
HDE is always ⇐ .22
How is the VWP determined?
VWP - Voluntary wait period (libCalc.mBuckets.Buckets)
VWP is the number of days to first breeding for this bred cow (where the cows are sorted in ascending order by days to 1st breeding) : .05*NumberOfBredCows rounded to the nearest whole cow.
For 100 bred cows, sorted by days to first breeding, the VWP is days to first breeding for the fifth cow.
