The performance of your dairy heifer calves can make all the difference to the profitability of your herd. We have visualised the latest research on keeping heifer calves happy, healthy and as profitable as possible. Take a look at our infographic below.
Staying healthy from day dot
The first few months of life? They are a critical time for any animal. It’s no different with dairy heifer calves. But did you know that performance of the young calf can determine its lifetime productivity? Growth rates during the first two months are especially important. And the healthier your calves are, the better their growth rates will be, and the more profitable your herd is likely to be.
Each heifer calf’s growth rate can have a direct impact on:
- age at first calving - longevity in the herd1 - milk yields during first and second lactation2
It’s a remarkable finding. One that makes it vital to make sure your calves get precisely the right care during their first weeks of life.
So we have established that keeping young calves healthy is important in ensuring they grow up to be productive dairy cows. That makes it crucial to protect the respiratory health of your calves. Good respiratory health is important for a calf’s wellbeing, and essential for good growth and profitable lifetime performance. You could add more than £7503 to the lifetime value of each heifer by looking after their respiratory health when they are young. Yet 67% of cases of pneumonia are estimated to occur in calves less than three months old4.
How can you improve respiratory health?
The list of best practices on calf management is long. But there are four basic principles you should follow to help protect the respiratory health of your calves:
Ensure optimal colostrum intake - Colostrum is a vital source of antibodies that boost calves’ immune systems and help to keep them healthy. Aim for at least 10% of body weight in the first 12 hours, with at least 3 litres given in the first 2 hours after birth.
Vaccinate early - Combined with other measures aimed at ensuring good respiratory health, early protection, through vaccination, against the key viruses should be an integral part of good calf management.
Manage group size - From 8 weeks of age calves should be group-housed. Grouping pre-weaning can reduce the risk of infection. Ideally there should be no more than 30 calves sharing the same airspace.
Happy housing conditions - The housing for your calves should be warm, dry and draught-free, with enough ventilation to prevent the build-up of viruses and bacteria.

Carolyn qualified from the RVC in 1995, and following time in mixed veterinary practice in Gloucestershire joined Zoetis (previously known as Pfizer Animal Health)in 2000 as a field based veterinary adviser.
In 2003 Carolyn became National Veterinary Manager focusing on young stock health, respiratory and infectious disease, and emerging diseases within the cattle sector. During this time she has sat on various committees including the British Cattle Veterinary Association Council, the NBA health committee, and the DEFRA farm health planning sub-committee (beef), and continues to be actively involved in various industry bodies.
Although now based ‘down south’ Carolyn still considers herself a true Yorkshire lass, and wishes she could be on the side of a hill in the Dales somewhere with her bonkers black labrador!
