OnglonFrom lameness to lesion
Footbaths: Prevention, Not Treatment
A footbath is a herd prevention tool for digital dermatitis pressure — not a cure for an active painful lesion waiting in the chute. Concentration, cow passes, and cleanliness decide whether the bath reduces new cases or just paints dirty heels.
RumenPhysically effective fiber
Overmixing Steals the Mat
Your ration might look perfect on paper, but if the mixer grinds your forage too fine, you lose the physically effective fiber required to build a healthy rumen mat.
PisMastitis pathways
The stall bed is half the teat environment
Between milkings the teat lives on the stall bed. Wet, dirty bedding is a continuous environmental bacterial dose.
TransitionThe transition cow
When the fresh cow’s energy gap widens
After calving, milk demand rises faster than intake — the gap is where ketone risk lives.
ÉtableStocking & cow flow
A rising fetch list is a time-budget failure
Robots succeed when cows choose the box and still get 12–14 hours lying. A climbing fetch list means the barn is stealing that time.
OnglonFrom lameness to lesion
Camera scores are screening — not diagnoses
Computer-vision gait scores can prioritize cows and track herd trends — useful screening when camera setup is honest, never a veterinary diagnosis on their own.
RumenInside the rumen
Saliva is the free buffer
Bagged bicarbonate has a line item. Saliva is the free, manageable buffer you earn with chewing — not the larger proton sink than SCFA absorption.
RumenPhysically effective fiber
Chop length is not peNDF
Chop length is a harvester setting; peNDF is the fiber structure that actually reaches the rumen after moisture, processing, mixing, and sorting.
RumenInside the rumen
Reading milk fat as a rumen alarm
A falling fat test is often the first cheap signal that fermentation has shifted, not that the cow forgot how to make fat.
RumenStarch load & SARA
Milk fat depression starts in the rumen
High starch and unsaturated fat with weak effective fiber can shift biohydrogenation toward trans-10 intermediates that suppress mammary fat synthesis.
ÉtableStocking & cow flow
Hidden stocking is lockup plus hold
The stall sheet said 100%. The cows stood from breakfast through the second parlor turn.
TransitionThe transition cow
Dry period is recovery time
A controlled dry period plus close-up bunk access is mammary recovery time — not an empty parking lot before calving.
