Autumn can be a high-risk period for calf pneumonia on Irish farms, with stressors such as weaning and housing reducing the ability of the immune system to fight disease.

One farmer familiar with this challenge is Albert Murphy, who runs 40 suckler cows on 90ac in Soran, near the village of Ballinalee, Co. Longford.

Albert said: “In the past, when we were weaning calves at the backend of the year, about a fortnight into housing them we had to deal with a bit of coughing to begin with, which developed into pneumonia.

“I had one good 350kg weanling that got pneumonia, couldn’t get over it and died, unfortunately.

“That was a heartbreak and heartache.”

Implementing a vaccination programme

Albert’s decision to start vaccinating came after facing multiple cases of pneumonia around the time of weaning and housing four years ago.

“There had to be an alternative to relying on antibiotics and running up additional treatment costs.

“So I went to Harry Ferguson, my local vet at Longford Animal Health Centre, and he advised me to put a vaccination programme in place.

“He recommended Bovilis Bovipast RSP. I took his advice on board, began using it and saw immediate benefits.”

Bovine respiratory disease (BRD) is the most frequently diagnosed cause of death in cattle over one month-of-age in Ireland.

Pneumonia is the main clinical presentation of the BRD complex.

Animals with a history of BRD have reduced feed efficiency, lower daily gains, and can take up to two months longer to finish than their healthy cohorts.

Bovilis Bovipast RSP protects against viral infections caused by RSV and PI3 and provides the broadest protection against infection caused by Mannheimia haemolytica.

Mannheimia haemolytica is commonly found as the principal bacterial agent implicated in calf pneumonia, accounting for 15% of all BRD cases diagnosed on post-mortem exam in 2024.

The primary course of Bovilis Bovipast RSP consists of two 5ml doses, given four weeks apart, administered subcutaneously into the neck.

The primary course must be completed at least two weeks before stressful periods such as weaning or housing.

Planning ahead works well for Albert.

He said:“I like to have the primary course finished before weaning.

“Once the two doses are into them in good time, they go into the shed well covered.”

For his autumn-born calves, Albert also uses Bovilis INtranasal RSP Live.

He said: “It works quickly. You can give it to calves on the day they’re born and after a week they have protection in place.”

Bovilis INtranasal RSP Live is an intranasal vaccine that protects calves against two viral causes of pneumonia, RSV and PI3.

A single 2ml dose can be given intranasally from the day of birth, with onset of immunity seven days later and protection lasts for 12 weeks.

Alongside vaccination, Albert has additional measures in place to reduce stress at weaning.

On farm, this includes creep feeding 1kg meal per calf per day for four weeks pre-weaning and increasing to 2kg per day for two weeks post-weaning, weaning calves in small groups, and removing cows while leaving calves in familiar surroundings.

At housing, stress is minimised by weaning calves two to four weeks earlier, having a strategic dosing plan in place, keeping sheds clean, dry and well-ventilated and avoiding overcrowding.

Good lighting allows for close monitoring of stock and early identification of any sick animals.

Beef Welfare Scheme 2026

Like many farmers across the country, Albert has applied for the Beef Welfare Scheme 2026, which aims to enhance animal health, husbandry and economic efficiency on suckler farms by supporting key animal welfare actions.

Recommending the scheme, he said: “The measures are very worthwhile and well incentivised.

“Every suckler farmer should be taking part in it.”

Under the scheme, meal feeding pre- and post-weaning is mandatory, while vaccination against pneumonia and/or clostridial diseases and/or bluetongue and faecal or forage testing are optional actions.

A payment of €15 per calf is available for vaccination, up to a maximum of 45 calves (€675 in total).

MSD Animal Health offers a range of vaccines suitable for use as part of the scheme.

For pneumonia, options include Bovilis Bovipast RSP, Bovilis INtranasal RSP Live and Bovilis IBR Marker Live.

For clostridial diseases, eligible vaccines include Tribovax 10 and Tribovax T.

Albert concluded: “Since introducing vaccination, the animals are healthier and thriving better.

“It’s taken a lot of stress off me, and in the long run it works out a lot cheaper.

“So, to anyone considering a vaccination programme, go to your vet, work out a plan and they’ll set you on the right road.

“The key is to start early, before the high-risk period. After all, prevention really is better than cure.”
