Whether rearing beef cattle or dairy heifers, maximum weight gain during the low cost grazing season is clearly vital in the current financial climate, according to Zoetis vet Dave Armstrong. “So preventing performance losses due to roundworm burdens, or worse still deaths later in the season due to lungworm, are clearly sensible priorities,” he suggests.
Biosecurity, exotic diseases and supermarket supply chains were at the top of the agenda at the only dedicated one day event for the beef and sheep industry in the UK.
You now have a straightforward way of evaluating the effectiveness of your sheep lameness control strategy, thanks to a useful new flock assessment tool. The practical ‘Lameness Control Planner’ from MSD Animal Health gives you a simple, yet highly visual ‘where are you now’ method of identifying whether your lameness management protocol is unbalanced in any way.
How to improve the value of dairy-bred beef calves
As a farmer, you already know what makes your business tick. You don’t need us to tell you that optimising the value of each animal is the key to a successful business. But did you know the importance of the first three months in terms of maximising lifetime performance of your dairy-bred reared calves?
Why are the first three months of life so important?
The value of a beef calf is inextricably linked to growth rates and weight. What farmers may not fully appreciate is that reaching target growth rates requires tip-top respiratory health. Calves with lung damage don’t grow as well as they should. And the greater the lung damage, the greater the impact on daily liveweight gain.
Pneumonia is one of the most common calfhood problems. And it’s estimated that 67% of cases affect calves younger than three months old. Calves whose growth has been stunted by lung damage during the first few months of life, may never catch up. The link is clear: respiratory illness means poor growth which means reduced value.
How to improve respiratory health in reared beef calves
There are a few important steps in protecting your calves from respiratory illness:
- It’s important that newborn calves receive sufficient colostrum – which is packed with important antibodies
- Newborn calves should receive at least 10% of their bodyweight within their first twelve hours of life, half of which should ideally be given within two hours of birth
- Receiving sufficient colostrum is as important for bought in calves as it is for home reared ones, arguably more so
- When buying calves from known sources or direct from farm you can check this with the seller.
- The next step is to vaccinate against the common viruses that cause pneumonia in young calves. It’s perhaps one of the most important things you can do for their respiratory wellbeing
- Other key measures include ensuring calf housing is well ventilated, and draught-free, with plenty of dry clean bedding.
- Keeping young calves away from older cows and making sure no more than 30 animals share the same airspace will further reduce the risks.
Taking the time to get the simple things right helps ensure you minimise disease risk, and protect the health of your calves. Best of all, it will have a tangible impact on the lifetime productivity of your animals.

To treat or not to treat?
Should farmers treat their animals? As we move into an increasingly wet and humid summer, do you know the parasite burden in your area? Farmers should be wary that 2016 will not be a repeat of 2015, where parasite burdens were at a record low. In a very short time, Zoetis have seen full fly traps pretty much everywhere, starting very early in Dorset and then moving up the country and Nematodirus showing a very similar pattern, with high counts early in the season. Other diseases, such as Coccidiosis, have shown to have had a big impact on lamb rearing. To read the June addition of Parasite Watch, click here.
Evidence-based help from #parasitewatch
Clearly, effective control of internal parasites, without spending money unnecessarily on over-using wormers, can help improve lamb growth rates and get them away early. As previewed in the previous Zoetis newsletter, a localised early warning system using farm-based intelligence hotspots to help sheep farmers make more timely, evidence-based parasite control decisions has been launched by Zoetis.
Parasite Watch is based on a nationwide network of farms providing diagnostic samples through the summer. From these, real time information is available to farmers about parasite challenges in their local area. The system is already generating live information on the challenge from four key parasite types:
- Gastrointestinal worms – regular faecal egg counts (FECs) and growth rate monitoring to check for the onset of parasitic gastroenteritis.
- Nematodirus – regular FECs, weather data and other sources to give an indication of disease risk on sentinel farms.
- Liver Fluke – using risk and weather data, coupled with regular sampling on Parasite Watch farms, to provide early notice of predictable threats.
- Flies – data from Parasite Watch farms to prompt early warnings, possibly before it is noticeable around livestock, that fly populations are multiplying quickly.
Zoetis veterinary consultant, Dave Armstrong, says the aim of Parasite Watch is to promote timely decisions by farmers, in conjunction with their SQP animal health adviser or vet, to treat or indeed not treat.
The data collection process is led by Zoetis vets, who will also provide commentary and early warnings of parasite outbreaks and advice on challenges that could threaten sheep wellbeing and productivity.
In addition to data, Mr Armstrong says Parasite Watch farmers have also agreed to share their observations via Twitter. “Our aim is to create a resource of real-world and real-time sheep farming information that can help improve health and welfare decisions, and sheep enterprise productivity,” he says.
An advisory blog has also been created here where surveillance results and topical guidance will be posted. One of its early postings says, “2015 was a record low year for parasite outbreaks, but 2016 is unlikely to be the same. It is crucial not to get complacent.”

Stay on top of fly populations on farm to protect livestock productivity and welfare
Flies can be a costly nuisance to the UK’s cattle and sheep population. In addition to the irritation caused, flies can also transmit a number of diseases, causing both financial and welfare concerns. An effective plan for control should be implemented to control the seasonal surge in fly population numbers, and prevent the development of associated diseases and related productivity challenges caused by these parasites. Fly problems can occur any time between April and November, depending on weather conditions and geography.
There are many risks of not treating flies and external parasites on cattle and sheep, which include reduced milk yields of up to 20%1, increased incidence of summer mastitis, reduced calf weight gain and reduced reproduction in sheep.
In addition, flies are implicated in a variety of serious diseases, for example they can transmit New Forest eye in cattle and sheep.
Did you know?
- It only takes 10-20 head flies to have a negative economic impact on farm2.
- The horn fly will feed on blood from cattle up to 40 times per day – this could lead to blood loss and constant irritation for the animal2.

Having the right applicator whether injecting, drenching or pouring on is critical to overall good treatment result. The risks using the wrong applicators are many and following a few small guidelines can improve your animal health practice.
One thing’s certain about 2016 worm threat: It’s unpredictable!
From most areas of the UK, feedback suggests that last year was one with low to moderate roundworm burdens, according to Zoetis vet Dave Armstrong. “Where this was identified using good diagnostics,” he says, “economies from using fewer wormer treatments were possible with manageable risk rather than a fingers crossed approach.
Lamb growth is at its most efficient in the first 10 weeks, so the quicker you are able to rear your lambs to target deadweight, the more efficient the enterprise and in turn you will be able to reap the benefits of selling on to an earlier market.
Colostrum is often described as ‘liquid gold’ as the fuel for life. One secret to rearing healthy lambs, and for future production, is to make sure each lamb receives enough colostrum. Ad-lib feeding can often see lambs perform and grow better than they would had they been left on their mothers.
