Everyone knows that the dry matter composition of waste milk is 13 percent. Right?
No. Wrong!
I was pleased to find in a recent press release from Penn State the results of monitoring waste milk dry matter composition on nine dairy farms over a period fifteen days.
| Farm | Average | Minimum | Maximum |
| # | D.M | ||
| 1 | 10.7 | 10.1 | 11.2 |
| 2 | 10.5 | 9.4 | 13.9 |
| 3 | 10.1 | 9.3 | 10.8 |
| 4 | 10.5 | 8.6 | 11.7 |
| 5 | 10.3 | 8.3 | 11.0 |
| 6 | 10.1 | 9.0 | 10.9 |
| 7 | 10.2 | 9.8 | 10.7 |
| 8 | 10.8 | 10.2 | 11.8 |
| 9 | 10.3 | 9.7 | 10.6 |
Given the average dry matter from these nine farms is about 10.4 percent, the question is,”What rate of gain would we expect from feeding this milk to calves?”
