Study reveals high ketosis risk

Three quarters of dairy herds under threat, says research

A paper presented at the International Conference on Production Diseases in Farm Animals has suggested that three in four commercial dairy herds are at risk of ketosis.

Using data collected from 4,709 transition cows, across 130 dairy farms in the UK, Germany, France, Italy and the Netherlands, it was revealed that 39 per cent had ketosis.

It was also revealed that more than 75 per cent of the commercial dairy herds tested were likely to be at high risk of developing diseases during the calving period as a result.

Authors Geert Vertenten, of Elanco Animal Health, and Anna Berge, of the epidemiology unit at Ghent University in Belgium, used two sets of data, taken from between July 2011 and September 2012, to compile their evidence.

For their research, they monitored ketosis levels in cows seven to 21 days after calving, and found that there are some key indicators vets can look for when assessing if ketosis is causing a problem within a herd.

According to the research, indicators include if there is a five per cent or more annual incidence of displaced abomasums and if there are more than 10 per cent of cows at a body condition score of four or above, three weeks prior to calving.

If more than 40 per cent of the cows have higher than a 1.5 to one ratio of fat to protein at the first milk recording after calving, it is another indicator that ketosis is causing an issue within a herd.

"The audit data supports the observation that subclinical ketosis is indeed a hidden disease," said Vertenten. "It is important that vets can identify where there are opportunities to make positive interventions that will improve the health and welfare of the herd."

Marie Rippingale, chair of BEVA's Nurse Committee, said: "I am very proud to be a part of BEVA.

"This change will help to empower nurses to speak up and contribute, but more importantly, it will give them an opportunity to collaborate with other members of the equine veterinary profession to bring about change that is positive for all."

Farmer survey to reveal on-farm impact of bluetongue

A nationwide survey has been launched to better understand how the bluetongue virus is affecting UK farms.

Results will inform the support that farmers receive for bluetongue, as well as preparing the livestock industry for the future.

The short online survey is open to all livestock farmers, regardless of whether they've had a confirmed case of bluetongue on their farm. It asks how many animals have been affected, the severity of their clinical signs and how it has impacted farm business.

The survey takes five minutes to complete and is fully anonymous.

It is led by Fiona Lovatt, of Flock Health Limited, and the Ruminant Health & Welfare bluetongue working group, in collaboration with AHDB and the University of Nottingham.

Dr Lovatt says: "We need to find out what level of clinical signs farmers are seeing in their animals, whether they are experiencing mortality with BTV-3 cases, and what their appetite is to vaccinate in future for bluetongue serotype 3."

The survey can be found here.
