Dry off a dairy cow or buffalo about 60 days before her expected calving date, stop milking abruptly rather than tapering off, and move her onto a low-energy, low-calcium dry-cow ration. Research consistently shows that a dry period of roughly 40–70 days gives the best milk yield in the next lactation — shorter than 40 days or longer than 70–80 days measurably reduces it. Most of what goes wrong after calving — milk fever, retained placenta, ketosis, early-lactation mastitis — is actually decided during these eight weeks, not after the calf arrives.
The udder is not resting during the dry period — it is rebuilding. Secretory tissue that has been working for 300 days involutes, is cleared out, and regenerates before the next lactation begins. Cut that process short and the cow starts her next lactation with less functional udder tissue than she should have.
The numbers are consistent across studies. In one comparison of Holstein dairy cows, animals given a 60-day dry period produced 11,942 kg in the following lactation against 10,749 kg for cows dried for only 30 days (Improving Productive and Reproductive Performance of Holstein Dairy Cows through Dry Period Management, PMC). A separate analysis found that cows with a dry period of 40–70 days had higher energy-corrected milk in the first 100 days of lactation than cows dried for shorter or longer periods (Association of Dry Period Length with Mastitis and Reproductive Indicators, PMC).
On Indian smallholdings the temptation is the opposite: keep milking a cow that is still giving three or four litres, because that milk is today's income. Those last few weeks of milk almost always cost more in next-lactation yield than they earn.
Aim for 55–65 days. Below 40 days the udder has not fully regenerated. Beyond 70–80 days the cow tends to get over-conditioned, which raises the risk of ketosis and fatty liver after calving.
Many farmers reduce milking to once a day, then every second day, believing it is kinder. In practice, slow tapering keeps the udder partially active and leaves the teat canal open longer, which extends the window during which environmental bacteria can enter.
The better approach is abrupt cessation: milk her out completely at the final milking and then stop. Support it by cutting concentrate and green fodder for two to three days before dry-off so milk production is already falling. Do not restrict drinking water — that is an old practice that does more harm than good.
If a cow is still yielding more than about 10–12 litres a day, drop her concentrate and shift her to dry roughage for four or five days first, so that abrupt cessation does not leave the udder painfully engorged.
The first two weeks after dry-off and the last two weeks before calving are when the udder is most vulnerable to new infections. Milk the cow out fully at the last milking, disinfect each teat end, and use a post-milking teat dip. Keep her on clean, dry bedding — during the monsoon this means checking the standing area daily, because a wet, dunged floor is where environmental mastitis organisms multiply.
Watch the udder for the first week. Some firmness is normal; heat, marked swelling, pain or an abnormal secretion is not, and needs a veterinarian. Where udder health is a recurring problem on the farm, a herbal udder-support supplement such as Cattle Remedies Uddicin-H can be used alongside — never instead of — good milking and housing hygiene. Our guide to udder health supplements for cattle in India compares the options.
The goal here is maintenance, not gain. Good-quality dry roughage with limited concentrate is usually enough. Do not push energy — a cow that arrives at calving too fat mobilises body fat aggressively afterwards and is the classic ketosis and fatty liver candidate. Keep a balanced mineral and vitamin supplement going throughout; Cattle Remedies Verymin is a chelated mineral and vitamin mix formulated for this purpose, and our mineral mixture buying guide explains what to look for on a label.
Now the calf is growing fastest and the rumen needs preparing for the lactation ration. Introduce a small, gradually increasing amount of the concentrate she will receive after calving so rumen microbes adapt. This is also when you address milk fever risk. For the full picture, see our detailed article on the transition period in dairy cattle.
This is the part that surprises most farmers. Feeding extra calcium in the last weeks of pregnancy increases the risk of milk fever, it does not reduce it. A cow on a high-calcium dry ration switches off her own calcium-mobilising machinery; when demand explodes at calving she cannot respond fast enough and blood calcium crashes.
The practical implications:
Repeat milk fever cases on a farm are almost always a dry-period feeding problem rather than bad luck. Our article on milk fever in dairy cows goes into detail.
After calving, almost every cow goes into negative energy balance — she cannot eat enough to cover the energy leaving in milk, so she mobilises body fat, and the liver processes it. A liver already burdened by over-conditioning during the dry period handles this badly, which is how fatty liver and ketosis begin. This mechanism is reviewed in Increasing Milk Yield and Negative Energy Balance: A Gordian Knot for Dairy Cows? (PMC).
The primary control is body condition: aim to calve at around 3.0–3.5 on the 5-point scale, not 4. Where liver support is warranted around calving, Cattle Remedies Heprich is a herbal liver tonic used for metabolic support in this period — see the liver tonic buying guide for how it compares.
Yes, and you generally should if she is 60 days from calving. Reduce concentrate and green fodder for three to four days first so yield falls, then milk her out completely and stop abruptly. Watch the udder closely for the following week. If she was yielding well above this, discuss the dry-off plan with your veterinarian.
The same principle applies — about 60 days. Buffaloes are more often dried for too long than too short, because lactations end earlier and rebreeding is delayed. A very long dry period wastes feed and tends to leave the animal over-conditioned, so manage the calving interval rather than simply extending the rest.
No — not routinely. High calcium intake before calving suppresses the cow's own calcium mobilisation and increases milk fever risk. Keep dry-period calcium low, then supply calcium at and immediately after calving. If an animal has had milk fever before, ask your veterinarian about a specific pre-calving protocol such as anionic salts.
A well-managed dry period is one of the cheapest interventions available to an Indian dairy farmer: roughly 60 days of rest, an abrupt dry-off with good teat hygiene, restrained energy feeding, low calcium until calving, and steady mineral supplementation. Skipping it to capture a few more litres today reliably costs more milk tomorrow.
