ShutOut® made a real difference for our heifers
In 2024 the Dobson’s introduced ShutOut internal
teat sealant (ITS) to their first calvers and saw
immediate results.
“Despite one of the toughest, wettest springs
we’ve faced, udder health improved dramatically
after using ShutOut” says Ashleigh.
The numbers tell their story:
- SCC for 2-year-olds dropped 44% from
93,000 in 2023 to 52,000 in 2025. - Clinical mastitis cases among heifers fell 85% from 13 in 2023 to just 2 in 2025.
- By November 2025, 97% of heifers
were uninfected.
Internal teat sealant change delivers cost savings without compromising
results or animal health
James Stewart’s goals for drying-off are to
reduce Somatic Cell Count and clinical
mastitis and he says “from the results I have
seen over the years, I am sold on using an
internal teat sealant to prevent mastitis”.
“As a farm we want to reduce our SCC and
ShutOut® has been a great partner in that
process, and we will continue to use it. “

Setting your heifers up for future success
Located just north of Feilding in the Manawatu,
Richard Sinclair milks 410 cows on 195 hectares with
his wife Christine and two staff members.
Avoiding mastitis in heifers is really important to Richard. “ setting our heifers up for success. They are our best genetics and we want to do everything we can to make sure they get back in calf again. If the heifers are hampered by mastitis, it has a real flow-on effect to the second calving so an internal teat sealant gives them the best possible chance to succeed.”
