[QUOTE="Agriland RSS, post: 6891713, member: 105608"] [img]https://s3-eu-west-1.amazonaws.com/files.thefarmingforum.co.uk/images/agrilanduk.JPG[/img] Written by Billy Wickham UK farmers have been warned to be mindful of the increased risk of coccidiosis as they put calves out to grass. Dr. Tim Potter, from Westpoint Farm Vets, part of the VetPartners group, explained that during the housing period of a calf’s life, coccidiosis-causing oocysts can tend to build up. This increases the risk of contracting the disease for both beef and dairy calves as the spring progresses. [SIZE=5][B]Pre-turnout[/B][/SIZE] “As stocking densities increase pre-turnout, it’s harder to keep sheds clean and dry, so you generally see a spike in oocyst numbers in the environment – therefore a heightened risk of ingestion by calves,” he said. Coccidiosis is spread by faecal to oral transmission he explained, meaning contaminated water troughs, dirty udders or sucking on dirty fences are all possible routes of infection. “In addition to this, coccidiosis causing oocysts are sensitive to sunlight, so the dark corners in sheds can be a hotspot for oocysts, unless they’re decontaminated with an appropriate disinfectant,” Dr. Potter said. [SIZE=5][B]Turnout[/B][/SIZE] “Problems can also arise at turnout. Oocysts can survive for up to a year, so if a field was contaminated in the previous season, it’s likely that the following year’s calves will become infected upon turnout.” Spotting and treating coccidiosis early can help minimise impacts. Dr. Potter suggested looking out for calves that appear depressed, are eating less than usual, are not growing at the expected rate or have scour with fresh blood in it.

You may also see calves with their tails up demonstrating unproductive straining, with perhaps some mucus being passed, which is due to irritation of the gut lining.” Dr. Potter also emphasised the importance of considering your own farm history. “Waiting to see signs will mean gut damage has already occurred by the time you treat. [URL='https://s3-eu-west-2.amazonaws.com/cdn.agriland.co.uk/uploads/2020/04/Image-source-Bayer-Animal-Health-Damage-to-Gut-lining.jpg'][IMG alt="Image-source-Bayer-Animal-Health-Damage-to-Gut-lining"]https://s3-eu-west-2.amazonaws.com/cdn.agriland.co.uk/uploads/2020/04/Image-source-Bayer-Animal-Health-Damage-to-Gut-lining-1024x682.jpg[/IMG][/URL] Damage to the gut lining “If you’re concerned about coccidiosis following an outbreak last year, I’d strongly recommend speaking to your vet to discuss the best approach for reducing risk on-farm. “Similarly, if you’ve spotted symptoms then you’ll need to get in touch with your vet to get a diagnosis and identify the most appropriate treatment approach,” Dr. Potter said. Dr. Potter added that it is important to treat all the animals in the same pen, even if only one or two are showing symptoms. “It takes between 15 and 21 days from ingestion of the oocyst to shedding of more oocysts in the faeces, so if one animal is showing symptoms it’s likely that more have already been infected,” he concluded.
