Caring for a Pregnant Cow or Buffalo Through Gestation

Quick answer: A pregnant cow or buffalo needs steady body condition, balanced minerals and energy, and a carefully managed last two months before calving. Feed to maintain (not fatten) through early and mid-gestation, step up energy and protein in late pregnancy, keep minerals and vitamins adequate throughout, and use the dry period to prepare the udder and prevent milk fever. Always confirm pregnancy and calving dates with a veterinarian.

How long is pregnancy in cows and buffaloes?

A cow carries her calf for about 280–285 days (roughly nine months and a week). A buffalo carries a little longer, about 305–315 days (around ten months). Knowing the expected calving date helps you time the dry period, vaccinations and the move to the calving pen.

Feeding a pregnant cow or buffalo, stage by stage

Early and mid-gestation (first 6–7 months)

In the first two-thirds of pregnancy the calf is still small, so the goal is to keep the dam in good — not fat — body condition on good-quality green and dry fodder with a little concentrate as needed. Over-fattening now makes calving harder later. Keep clean water available at all times.

Late gestation (last 2–3 months)

About two-thirds of the calf's growth happens in the last trimester, so the dam's energy and protein needs rise sharply. Increase good concentrate gradually, keep feeding leafy green fodder, and make sure minerals and vitamins are adequate. Aim for a moderate body condition at calving — both thin and over-fat cows calve with more trouble.

Minerals, calcium and vitamins during pregnancy

Minerals and vitamins quietly decide how well a cow conceives, carries and calves. A daily chelated mineral mixture such as Cattle Remedies Verymin helps cover calcium, phosphorus and trace minerals through gestation; our guide to the best mineral mixture for cattle in India explains what to look for. Around calving, calcium demand jumps for colostrum and milk — Cattle Remedies Chelated Calcicril supports this transition, and our guide to the best calcium supplement for cattle in India covers how to use it. Importantly, do not overfeed calcium in the final week or two before calving, as this can actually raise the risk of milk fever; your veterinarian can advise on pre-calving mineral balance.

The dry period: the most important 60 days

For a milking cow, drying off about 60 days before the expected calving date lets the udder rest and rebuild and lets the dam put reserves into the calf. Good dry-period and transition feeding is the single biggest lever for a healthy calving and a strong next lactation. See our detailed guides on dry period management and the transition period.

Health care during pregnancy

• Deworming: follow your vet's schedule — a heavy worm burden drains both the dam and the calf.
• Vaccination: keep FMD, HS, BQ and brucellosis cover up to date as advised, but avoid handling and vaccination stress in the final weeks unless your vet directs it.
• Comfort and footing: non-slip floors, shade and space lower the risk of slips and abortion; trim overgrown hooves early rather than in late pregnancy.
• Liver and appetite: a herbal liver tonic such as Cattle Remedies Heprich can support appetite and metabolism in a run-down animal, under guidance.

Warning signs to call your vet about

Contact a veterinarian promptly for any vaginal discharge or bleeding before term, a cow going well past her due date, severe udder swelling with discomfort, sudden loss of appetite, or straining without progress. After calving, watch for retained placenta and milk fever — see our guides on retained placenta and milk fever.

Frequently asked questions

How long is a cow pregnant?

About 280–285 days for cows and 305–315 days for buffaloes, counted from the date of successful mating or AI.

What should I feed a pregnant cow?

Good green and dry fodder to maintain condition through early and mid-pregnancy, concentrate increased in the last two to three months, clean water always available, and a daily mineral mixture throughout.

When should I dry off a pregnant dairy cow?

Around 60 days before the expected calving date, so the udder can rest and the dam can prepare for the next lactation.
