Scours and Up-to-Date Information
So, here we are trying to pin down some possible management changes that could reduce scours treatment rates for preweaned calves on a dairy farm. Treatment rates since mid-March have been very high - not killing calves - taking a LOT of labor, however, to keep calves hydrated.
Colostrum bacteria culture data - yes - unfortunately the samples data are dated late November. At that time bacteria levels were at acceptable levels. A lot could change in four months?
Blood serum total protein data - yes - 37 samples of which 32 were from before March 1st. Using all 37 samples we find 78% equal to or above 5.2 (Goal=90%) and 73% equal to or above 5.5 (Goal=80%).
Looking only at BSTP since March 25th 67% were below 5.2. Not looking good here.
Diagnostic lab data are dated 11/19/12, 12/3/12, 12/4/12, and 12/8/12. At least these confirm that salmonella was not present. Basically everything else (viruses, bacteria, parasites) that is common on dairy farms was present.
Where are we going to start?
1. culture a current "as-fed" sample of colostrum
2. culture a current "as-fed" sample of milk
3. get as many current BSTP samples as there are calves between 1 and 7 days of age
4. On-farm observe feeding practices looking for consistency (seeConsistency check list) in management practices.
More on this case study after I have a chance to visit the farm.
