Kernfarm at VIV Europe

A remarkable Kernfarm booth at the VIV Europe in the Jaarbeurs Utrecht.

A sterile and boring exhibition booth? Not when you are Kernfarm! From May 31st to June 2nd, visitors of the VIV could meet Kernfarm and the team. The VIV is the event for livestock farming and this year, after a long time, it took place in the Netherlands again. A great opportunity for Kernfarm to get in touch with the sector. Kernfarm stood out with a grass floor, hay bales all over the place and a sturdy Landrover. “Looking for a solution? Join the ride!” was the slogan. The person who spotted the most FIXR® solutions in the Kernfarm landscape, could win a professional binocular. A fun way to show what Kernfarm has to offer to help veterinarians. Many new contacts have been made, this to grow internationally and expand the product range. The team is happy with the results of the event. We did it the Kernfarmway! Curious to see more?

Targeting worms together!

Targeting worms together!

Kernfarm introduced Flubenmix at the British Pig and Poultry Fair in the UK.

The Kernfarm Landrover Defender drove all the way to Warwickshire (UK). After 4 years, the famous British Pig and Poultry Fair was organised again (10th and 11th of May). Visitors were introduced to Kernfarm’s Flubenmix and competed against worms in poultry and pigs. ”GIVE IT A SHOT” could be heard all day. Bags of Flubenmix were thrown into animal mouths and participants won great prizes! A nice shot of whiskey and mixed nuts (because we are not nuts) were handed out. Kernfarm is looking back on a very successful event. Like to see more photos? Check our socials.

Kernfarm eyes vaccine portfolios – Animal Pharm News

Kernfarm eyes vaccine portfolios, strategic partnerships to become leading provider 


In 2017, Kernfarm was named the number one fastest-growing company in the Netherlands. With a portfolio of 150 animal health products and over 250 clients across Europe, the start-up spoke to Animal Pharm analyst Sian Lazell about tackling the needs of livestock veterinarians and its future plans for growth.

Based in Utrecht, good manufacturing practices-certified animal health company Kernfarm is working to expand its capability as a leading provider of livestock medicines.

The name Kernfarm translates literally as ‘core farm’, reflecting the business’ aim to become the go-to provider for livestock medicines.

The firm’s portfolio is a mix of its own-brand products and those from the animal health industry’s big pharma companies. Over the last four years, it has used its strong connection to veterinary clinics across Europe to identify unmet needs in the livestock market and deliver solutions.

Kernfarm has a two-way approach – not only does its stock products from the big players, it also locates products with good market viability and registers them under the Kernfarm brand in new territories where they are needed.

The company was established by three brothers: Tim van Rijn, Gijs van Rijn and Diederik van Rijn, all of whom are directors of the company. Collectively, they bring together backgrounds in agricultural management and animal health, innovation management, as well as business and finance.

Most of the products stocked by Kernfarm at present are registered by other businesses but the firm has two undisclosed products of its own in development and is currently working to launch another under the Kernfarm brand.

This branded product is Trichoben, which is a vaccine for the prevention and therapeutic treatment of the fungal skin disease trichophytosis in cattle and can be administered from one day of age. Kernfarm is launching the product in the Netherlands and Belgium at present.

Tim van Rijn said: “It’s fair to say the livestock sector in is a thriving market but one heavily dominated by a few large pharma companies and many regulations.

“These factors are not making it easy for newcomers to enter but once they can get in, there is a good opportunity to bring new products to larger markets.”

Kernfarm has used Diederik van Rijn’s background in veterinary pharma and agribusiness management to build strong connections with over 250 veterinary practices, to find out what vets need in different areas.

Tim van Rijn explained: “We usually create collaborations with pharma companies outside of the Netherlands. Then, if it is feasible to get their products registered in another country where they are needed, we facilitate that.”

Kernfarm also prides itself on being able to source products for vets that are low in stock elsewhere. It credits this ability to its good overview of the EU market in general and its strong connections to different sized pharma firms.

Tim van Rijn said: “As long as there are stock issues, which are getting more frequent, this business model is quite sustainable. There has been a lot of acquisition and optimization of manufacturing from bigger firms. Manufacturing – especially for vaccines – is so complex that supply challenges occur often. The bigger companies also see problems with stock allocation on the market.”

Jo Weston, marketing and communications manager at the firm, added: “As a small company we are able to adapt to a changing market and we don’t work with fixed supply numbers.”

Outlook for growth

Kernfarm was established four years ago and now has a workforce of 12 people. In the next five years, the company is aiming to see 80% of its turnover represented by its own brand products.

Although the firm is currently focused on the livestock space, it has not ruled out looking at the companion animal market in the future.

Kernfarm provides a range of products but it has a particular interest in vaccines and plans to focus investment on the acquisition of vaccine dossiers over the next few years.

The company told Animal Pharm: “It is very much our goal to be a partner of both big and small companies in the industry.”

Top tips for smallholders to eradicate worms

Poultry worms can cause weight loss, diarrhoea, reduced productivity, anaemia, and even – in serious cases – death. Yet many smallholders are unaware of the need to treat their poultry regularly with a medicated wormer to tackle these pernicious parasites. So what do they need to know?

According to Diederik van Rijn, founder of veterinary pharmaceutical firm Kernfarm, there are four main types of worms to look out for:

  • Round worms (Ascaridia Galli), which are white and 5 to 8cm long. These are the most common worm and live in the middle intestine, causing gut damage, blockage, and inflammation. Symptoms include diarrhoea, weight loss and pale, anaemic combs and reduced egg production.
  • Hair worms (Capillaria) are small and barely visible to the naked eye. These worms live in the upper digestive system and cause appetite loss, weight loss, diarrhoea and dull or depressed birds.
  • Caecal worms (Hetarakis Gallinarum) live in the caeca of the gut and don’t cause any particular problem on their own bar yellow droppings. However, they carry another parasite; Histomonas, which in turn can cause Blackhead, and leads to increased mortality in a flock due to liver damage.
  • Gape worm (Syngamus trachea) are perhaps the most recognisable but least common worms. They live in the trachea and cause gasping, head shaking and respiratory issues.

“All birds are likely to get worms at some point – but quite often smallholders aren’t aware of the risks,” explains Sophie Wilkinson, veterinary adviser at VioVet. As well as the immediate damage caused by the intestinal parasites, they can also lead to secondary infections as bacteria can pass through the gut wall more easily. Producers may also see an increase in vent pecking as well as reduced egg productivity and shell quality.
Practical measures

Worm eggs thrive in wet, warm, muddy areas, and they cannot develop when it is very dry, below 10˚C or above 35˚C. They are also destroyed by ultra-violet light from the sun, so there are practical changes producers can make to reduce the worm pressure, says Ms Wilkinson.

“Clean out coops regularly with disinfectant, and keep the bedding clean and dry. Also, move the run around onto fresh grass if possible.” Keep the grass short to maximise exposure to the sun, and try to remove muddy areas by creating hard standing or using free draining gravel.


Even with these measures, poultry are still likely to pick up internal parasites, so it’s important to check them regularly. This means taking a faecal sample and sending it off to identify the number and type of worms present. “Do this every three months, and if there is an issue treat the birds with a medicated wormer,” she explains. “If there is a high worm burden I’d treat them again three weeks later.”

Many smallholders like to use herbal products to boost bird health, but these are not proven to work against worms, she adds. “A licensed, medicated wormer must be clinically proven to work – and until recently there was only one anthelmintic recommended for use in poultry.”

A cost-effective alternative

However, there is now a second choice, which means medical treatment does not have to be too costly. The new wormer – Flubendazole 1% – is medically exactly the same as the existing market leader, but is considerably cheaper, saving poultry keepers up to 25% in price. “Using a medically proven wormer is the only way to effectively treat infected birds,” explains Mr van Rijn.

Made specifically for small holders of chickens, geese and turkeys, this anthelmintic is effective against gapeworm, large roundworm, caecal worm, hairworm and gizzard worm. Activity includes adult worms, larvae and eggs – targeting the whole worm life cycle.

Given in feed, it is easy to administer, and there is no egg withdrawal period, so eggs can still be eaten during the treatment, he adds. “Everyone wants their birds to be healthy and productive, and they can now ensure that without breaking the bank.”

Save money and boost bird health with new wormer

Poultry smallholders could save up to 25% – and boost bird health and productivity – by using a new medicated wormer to tackle internal parasites.

Kernfarm, veterinary medicines, diergeneesmiddelen veehouderij

“Historically, smallholders have faced a decision between treating poultry with a relatively costly medicated wormer, using preventative herbal products which don’t kill worms, or just leaving them untreated in the hope that they don’t get sick,” explains Diederik van Rijn, founder at Kernfarm, which manufactures the new product. “Now, they can use a tested and licensed medicated wormer at a fraction of the price – it’s a win-win.”

Chickens, geese and turkeys are affected by several species of parasitic worms, which can lead to a variety of health problems. “Whether you have free-range or housed poultry, worm burdens can quickly build up if left untreated,” explains vet John Kenyon from St David’s Poultry Team. Common worms include roundworms, hairworms, and caecal worms – which can cause the fatal disease Blackhead.

Symptoms of worm infections include poor weight gain, reduced egg quality, anaemic birds with pale combs, increased vent pecking, egg peritonitis, and in heavy infestations, death. “For this reason it is important to regularly worm your flock, every 3–4 months,” says Mr Keynon. “We recommend worming with products that are specifically licensed for use in poultry as these have been proven under strict testing conditions to be effective against the species of worms found in poultry. You can even continue to eat the eggs your birds lay during the treatment.”

The new wormer – Flubendazole 1% – is medically exactly the same as the existing market leader Flubenvet 1%, but is considerably cheaper, saving poultry keepers up to 25% in price. Made specifically for chickens, geese and turkeys, it is effective against gapeworm, large roundworm, caecal worm, hairworm and gizzard worm. Activity includes adult worms, larvae and eggs – targeting the whole worm life cycle.

“Poultry keepers can ask for Flubendazole 1% from their vet or wholesaler,” says Mr Van Rijn. “When it comes to bird health and productivity, only the best will do – but it doesn’t have to cost the earth.”

Kernfarm, No. 1 fastest growing start-up NL looks forward to first product launch in 2018

15 Dec 2017

In the aftermath of last nights’ FD gazellen awards, where Kernfarm went on to win the National #1 position as fastest growing start-up, the van Rijn brothers look ahead to 2018 and the launch of their first Kernfarm branded products.

Speaking on BNR Radio this morning, Diederik van Rijn one of the company founders said: ‘’ We are working hard to offer a choice of products alongside a high level of service to veterinarians across Europe. The team are excited about introducing our first product, a ruminant vaccine, early in 2018 and building the Kernfarm portfolio. Watch this space!’’

Kernfarm has sucessfully built a unique innovative business model within a traditional market – opening up the trade in pharmaceuticals for livestock across Europe. This is valued by veterinary practices and wholesalers, whom in recent years, have experienced a loss of power and freedom of choice partly due to the acquisition of pharmaceutical companies, widening the distance between supplier and vet. Kernfarm endeavours to bring that personal touch back by listening to the needs of vets and offering tailor-made solutions. From innovative trading initiatives to new product registrations for smaller market or out of stock products.


Background information Kernfarm:

Kernfarm is a family pharmaceutical company, set up in 2014 in the Netherlands by three brothers – Tim, Diederik and Gijs van Rijn. Kernfarm partners with large and small livestock pharmaceuticals, wholesalers and veterinary practices across Europe supplying pharmaceutical products to support the farmer to improve livestock welfare. Kernfarm has made a flying start and through strong international trading network has created a position for itself in the market, traditionally dominated by a few large players. In the last two years their assortment has grown to more than 100 products delivered to 150+ veterinary practices within Europe.
