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."

Cats Protection launches Christmas animation

News Story 1
 Leading feline charity Cats Protection has launched a heartwarming Christmas animation to raise awareness of the important work it does. The animation is based on a true story of a kitten that went missing earlier this year. Freezing cold and hungry, the kitten was dumped in a box on a roadside and somehow became separated from her brother and sisters.

Thankfully there is a happy end to this tail, and Libby - now named Misty - was eventually reunited with her littermates. Misty’s owner, Amy Smith, said: “Misty has settled amazingly well into our home, she has found a best friend in my daughter Lily and likes to follow her around the house. She also loves to chase bugs in the garden. We feel very lucky to have her.”

WSAVA launches certificate programme focusing on companion animals in One Health

The first certificate programme focusing specifically on the role of companion animals in One Health has been launched by the One Health Committee (OHC) of the World Small Animal Veterinary Association (WSAVA).

The online programme, which is free of charge for WSAVA members, has been developed in recognition of the growing impact of companion animals in human society. Pet ownership is becoming more popular globally, and this has increased the implications for One Health, regarding the human-companion animal bond. The WSAVA OHC hopes that this course will bridge the knowledge gap between veterinary surgeons and human physicians. New modules are being added weekly, with a total of 20 modules expected to be available by early 2020.
