During these times something caused a breakdown in your mas titis control program. Ask yourself several questions. Was there a new milker? Were some milking procedures changed? Was there a breakdown in the milking equip ment? Was a newly purchased cow added to the herd that could have brought in contagious organ isms? Or can it all be blamed on Use SCC Report the weather? Now that you have an idea where the breakdown occurred, make changes to correct or prevent them from happening again. By looking at how many times a cow was severe during her lacta tion will help in deciding her dis position. She will be listed as severe each time her LS is 4 and above. Of course deciding to cull her or to dry her off early will depend upon several factors. Her age or numbers of lactations, and if she is confirmed pregnant are just a few considerations.

Have your veterinarian or a trained person take aseptic milk samples from a representative group of cows with SCC scores 5 or higher. These cows should not have been treated for at least S days prior to sampling. Samples should be cultured to learn what organisms are causing the masti tis. They should also be checked for antibiotic resistance to deter mine the best drug therapy.

By finding chronically infected cows, management pro cedures can be practiced to help meet your goals. 1. Milk high SCC cows last., 2. Dry high see cows off early. 3. Don’t put milk from high SCC cows in the bulk tank, espe cially if close to losing premium. 4. Don’t buy mastitis. Check SCC before purchasing. SCC should be less than 4. CHECK LIST THAT HELPS TO LOWER SCC. 1.
