Dairy Calf Rearing: 7 Steps Farmers Can Follow to Reduce Calf Losses and Build a Healthy Herd

A healthy calf is the foundation of a productive dairy herd. Poor nutrition, dirty housing and delayed disease treatment can increase mortality and slow growth. The Indian Council of Agricultural Research recommends paying particular attention to newborn calves because the first few weeks are critical for survival, immunity and future productivity.

ICAR’s dairy farming guidance recommends feeding adequate colostrum soon after birth, maintaining clean calf housing and providing suitable nutrition as the animal grows. Farmers should adapt feeding quantities and management to the calf’s age, breed, body condition and local veterinary advice.

Seven Steps for Better Calf Management

1. Give colostrum soon after birth

Colostrum is the first milk produced by a cow after calving and contains antibodies that help protect the newborn calf. The calf should receive good-quality colostrum as soon as possible after birth because its ability to absorb these protective antibodies decreases rapidly during the first hours of life.

Farmers should monitor whether the calf is able to suckle properly. If it cannot nurse, seek veterinary assistance rather than waiting. Keep feeding utensils clean and avoid giving contaminated milk or water, which can increase the risk of digestive illness.

2. Keep the calf area clean and dry

Newborn calves are vulnerable to infections, particularly when housing remains wet or contaminated with manure. Provide a clean, dry and well-ventilated area protected from extreme weather. Replace damp bedding regularly and remove manure before it accumulates around feeding and resting areas.

Good ventilation does not mean exposing calves to strong drafts. The housing should allow fresh air while protecting young animals from rain, cold winds and excessive heat. Separate sick calves from healthy animals where advised by a veterinarian to reduce the spread of infection.

3. Feed milk according to age and condition

Milk is an important source of nutrition during the early stage of calf growth. Farmers should follow a feeding schedule recommended for the calf’s age and body weight rather than giving an arbitrary quantity. Sudden changes in milk quantity or feeding times can contribute to digestive problems.

Use clean containers for every feeding and wash them after use. Farmers using milk replacers should follow the manufacturer’s mixing instructions and avoid making the mixture unnecessarily concentrated. Veterinary or dairy specialists can help design a feeding programme suited to local conditions.

4. Introduce clean water and calf feed

Calves need access to clean drinking water as they grow. Farmers should provide water in clean containers and replace it regularly, particularly during hot weather. Water intake supports normal development and becomes increasingly important as the calf begins eating solid feed.

Starter feed can be introduced according to local dairy recommendations as the calf develops. Good-quality calf starter encourages the digestive system to adapt to solid feed. Farmers should introduce new feed gradually and monitor appetite, dung consistency and body condition for signs of digestive problems.

5. Protect calves from diarrhoea

Diarrhoea is a major concern in young calves and can quickly cause dehydration. Farmers should watch for loose dung, reduced appetite, weakness, sunken eyes or other signs of illness. A calf with severe diarrhoea may require prompt veterinary treatment and fluid support.

Do not wait for the animal to become severely weak before seeking help. Maintain clean feeding equipment, provide good-quality colostrum and keep housing hygienic to reduce preventable risks. Farmers should follow veterinary advice on treatment rather than using antibiotics or other medicines without proper diagnosis.

6. Follow vaccination and deworming advice

Vaccination schedules vary according to region, disease risk, age and government veterinary programmes. Farmers should obtain the local schedule from a veterinary officer or animal husbandry department and maintain a record of every vaccination.

Deworming should also be based on veterinary advice and local parasite conditions. Avoid repeatedly giving medicines without checking whether treatment is required. Keeping records of vaccination, deworming, illness and treatment helps farmers identify recurring problems and ensures that important doses are not missed.

7. Monitor growth every month

Regularly checking a calf’s weight or body development can reveal problems before they become severe. Farmers should record birth date, feeding history, illness, treatment and growth. If a calf repeatedly fails to gain weight, veterinary or dairy specialists should investigate possible nutritional, infectious or management causes.

Healthy growth is not determined by size alone. Breed, sex, feeding system and age influence body weight. Farmers should compare calves against suitable standards rather than assuming that every animal should reach the same weight at the same age.

Reduce Future Herd Costs

Good calf management requires daily attention, but it can prevent losses that are more expensive to address later. Clean housing, timely colostrum, appropriate feeding and disease monitoring should form the basic routine. Farmers should also isolate visibly sick animals when recommended and contact veterinary services early.

Farmers can maintain a simple calf register with birth date, colostrum feeding, vaccinations, deworming, illness, treatment and monthly growth. These records can help identify which management practices are working and provide useful information when a veterinarian examines an animal.

A calf that survives the early months is not automatically a healthy replacement animal. Nutrition, hygiene, disease prevention and steady growth all matter. Farmers who establish these practices from birth can improve the chances of raising stronger animals for the future dairy herd.
