Following the GenoCells results each quarter of the high SCC cows were tested with the California Milk Test (CMT) to identify any mastitis issues in individual quarters. This reduced the farm antibiotic use in cases where cows only have one quarter that was infected with higher SCC.
Samples were taken prior to drying off the herd and this data was shared with current farm vet, Guy Tomlinson, and decisions were made using the data for individual dry cow treatment. All cows tested with 200+ SCC and that spiked in the last three months of lactation got antibiotic and sealant treatment, and sealant only was used on all cows under 200 SCC.
After calving further GenoCells samples were taken and sent to the lab, Table 1.

Five cows in their 3rd lactation or younger with 250+ SCC post calving received an AHV bolus as treatment.
