Kalfsupport

What Kalfsupport does

Kalfsupport is a privately held Dutch B.V. (besloten vennootschap) founded in 2013 by Leo Hulter and headquartered in Gramsbergen, Overijssel, Netherlands. The company is a specialized calf-rearing (kalveropfok) consultancy and product distributor serving Dutch dairy farmers, built around an integrated advisory-plus-products model that covers six pillars of calf rearing: nutrition, health, housing, hygiene, management, and stable climate. Field-based Kalveropfokspecialisten (Calf Rearing Specialists) conduct on-farm consultation visits, offering free advisory appointments and a sample bucket of Structo Stimulans as an onboarding incentive.

The product portfolio is anchored by the Maxilac calf milk powder range (Flex 50, Comfort, Flex No Limit, Flex Protect, Optimaal, Efficiënt, Maxistart Rood, Flex Lam Start, Flex Lam Opvolg), distributed exclusively in the Netherlands by Kalfsupport under a partnership with Klaremelk, complemented by the proprietary Kalfsupport Subliem 60 milk powder and a full line of own-brand concentrated feeds (Structo Stimulans dry TMR, Pens Actief, Junior, Basis, Vitaal Plus, Rosé Start, Rosé Afmest, Vita-Lam). Supporting categories include mineral supplements (Kalfsupport Jongvee Mineraal, Kei-Vit liksteen), health products (Maxifit, Globigen Dia Stop, Globigen Colostrum, Kalfsupport IJzer-Bolus, Bicar-Bolus, Kalf-Spirine, Kalf-Vit, Kalf-Fizz, PrimeHumic), calf housing equipment (KMAX3 Outdoor mobile calf box, Kalfsupport Boogstal portable housing), and hygiene and feeding accessories. Notable technical components include Diamond-V's patented SmartCare fermentation metabolite technology in Maxilac Flex Protect, and proprietary formulations containing Rumicox+ (essential oil / natural extract premix for coccidiosis suppression).

Kalfsupport monetizes through direct sales of calf milk powder (delivered per sack goods or in pallets/bulk), concentrated feeds (big bag, sack goods, or bulk silo delivery), calf-rearing consumables and equipment, and on-farm consulting services. Pricing is pay-as-you-go unit-based and not publicly disclosed; new customers must contact the company for onboarding. Distribution runs through an authenticated online ordering platform (kalfsupport.nl/bestellen) launched with PWA mobile functionality in 2025, the kalfshop.nl e-commerce storefront for equipment and consumables, and the field-sales channel. The company holds a dense stack of certifications — GMP+ FSA, GMP+ FRA, GMP+ MI 105 (GMO Controlled), SecureFeed participation, NZO white-list registration, and VLOG non-GMO certification — that act as procurement gates for Dutch dairy processors and German VLOG-aligned buyers. Ownership is concentrated with founder Leo Hulter; the business is bootstrapped with no institutional investors, no parent company, and no disclosed funding rounds.

Scale indicators3 records

Recent moves6 records

Expansion highlights5 records

Direct peers

• Schils (Schils BV): Dutch specialist in young-animal nutrition including calf milk replacers and calf feeds; the closest direct peer in product and geography, both focused on calf-rearing feed solutions for dairy farmers.
• Denkavit: Specialist manufacturer of calf milk replacers and young-animal feeds with a focus on ruminant nutrition; directly comparable as a specialist in the same calf-rearing product category, though Denkavit operates at multi-country scale versus Kalfsupport's Netherlands-only footprint.

Broad incumbents

• ForFarmers: Large European feed company supplying compound feeds, including young-animal and dairy feeds, to farmers across the Netherlands and other EU markets; comparable product categories but with a much broader portfolio and geographic reach.
• Trouw Nutrition (Nutreco): Global animal nutrition subsidiary of Nutreco offering young-animal feed programs, premixes, and on-farm advisory services; comparable in combining feed products with technical advisory for dairy and livestock producers, though at much greater scale.
• Agrifirm: Dutch agricultural cooperative and major feed manufacturer offering calf milk replacers, concentrates, and on-farm advisory across livestock; overlapping product categories but operating at national scale rather than the calf-rearing niche Kalfsupport occupies.
• De Heus Animal Nutrition: Major Dutch-headquartered animal feed manufacturer selling complete feeds, concentrates, and young-animal nutrition globally; directly comparable on the calf-feed product side though with a broader species and species-life-stage portfolio.

Others

• GD Diergezondheid: Dutch Animal Health Service providing diagnostics, herd health monitoring, and veterinary support to Dutch livestock farmers; Kalfsupport's partner but also an adjacent ecosystem player serving the same farmer base with animal-health rather than nutrition solutions.
• FrieslandCampina: Largest Dutch dairy cooperative and major buyer of Dutch farm milk; not a direct feed competitor but a critical upstream player whose sourcing requirements (e.g., non-GMO, quality programs) shape demand for feed suppliers like Kalfsupport.
• Lely (Lely Industries): Dutch dairy equipment and automation company (milking robots, feeding, housing); not a feed peer but a comparable Dutch dairy-farm ecosystem player serving the same farmer customers with adjacent on-farm solutions.

Emerging players

• Klaremelk: Producer of the Maxilac calf milk powder programme that Kalfsupport distributes exclusively in the Netherlands; comparable as a calf milk specialist, with the relationship being both partnership and partial competition if Klaremelk ever changes its exclusive arrangement.
