Our purpose

Every formulation, field visit and dose is built around one thing: measurable impact that lasts beyond the prescription.

The stakes

Every year, preventable cattle disease costs Indian dairy farmers an estimated

₹0 crore / year
Lost, but preventable

Behind that number is an animal that should be standing, and a household that should be holding. This loss is preventable, and that conviction is why Ontra exists.

What challenge are you addressing?

Go from a symptom to the science, and the products built for it.

When cows fail to show clear signs of heat, or do not cycle at all after calving, rebreeding is delayed, calving intervals lengthen and lifetime productivity falls.

Yesheat 500 Kit

After calving, intake lags demand. Body fat mobilises faster than the liver can process it, driving ketosis, poor intake, weak heats and a slow, costly start to lactation.

Built for this
Bilicholine Liquid
Read the science →

Rising temperature and humidity cut dry-matter intake, suppress oestrus expression and pull down milk yield long before an animal looks visibly unwell.

Built for this
Bovifill Liquid
Read the science →

Sub-clinical worm burden quietly drains condition, growth and milk. Strategic deworming, timed to the season, protects both the animal and the margin.

Built for this
Ontra Deworming Protocol
Read the science →

A lame cow eats less, walks less and breeds later. Hoof health is a productivity problem long before it becomes a treatment problem.

Built for this
Mineral & Hoof Support Range
Read the science →

A vector-borne viral disease that spreads fast through a shed. Supportive care, recovery nutrition and vector control decide how much of the herd comes back.

Bovifill Liquid

The single largest cause of discarded milk and early culling. Sub-clinical cases cost most, because they are never seen.

Built for this
Udder Care Range
Read the science →

At calving, calcium demand spikes. When mobilisation cannot keep pace, the cow goes down, and the risk of retained placenta, ketosis and mastitis rises with it.

Built for this
Calhorn Advance Gel
Read the science →

Stress at milking blocks oxytocin release. Milk is made but not released, residual milk rises, and yield and udder health both suffer.

Built for this
Calhorn Advance Bolus
Read the science →

A cow that does not rise within hours of calving needs energy, minerals and nursing together. Time is the variable that decides the outcome.

Built for this
Bovifill Liquid

Treatment ends the disease. Recovery nutrition decides whether the animal returns to full yield, or never quite gets back there.
