We work closely alongside farmers, veterinarians and scientists to constantly expand our knowledge, which we are then happy to share with you.

| Housing

It is essential that you first (thoroughly) clean the calf pens before disinfecting them (among others for crypto) to reduce the infection load and the risk of disease. Leaving the pens empty and sunlight are valuable additional tools.

| Housing

The first fourteen days in the life of a calf are crucial for the animal’s health, and for its future development. Accommodation has a huge influence. The calf deserves a clean, dry and warm environment. In a clean cubicle, with a thick layer of straw.

| Milk powder

When you know that depending on the type of powdered milk you administer, it will take anything between one and a half and five hours for the calf to process their feed, you will probably start to wonder whether it is not in fact better to feed a calf three times a day. “It certainly increases the rate of growth,” suggested Sjaak. “But it also means maintaining the same pattern in the weekends, too.” An automated calf milk dispenser can offer a solution.

| Colostrum, Milk powder

When asked which is best, a teat or a bucket, Sjaak gave a clear response: a teat. “The calf has to work hard at obtaining its milk. In addition, the posture is better when drinking from a teat, so the risk of powdered milk finding its way into the rumen is reduced.”

| Milk powder

Every bag of powdered milk features a feed timetable. According to Johan Verdaasdonk, young stock specialist of FrieslandCampina, it offers an ideal guide for the calves. “Never exceed 3.5 litres per feed,” Johan warned. “Four litres per feed means overfeeding.

| Colostrum

A new-born calf is vulnerable. It has no natural antibodies and during the first few weeks the calf’s own immune system is still insufficiently developed to fight off infection in the intestine (diarrhoea) or lungs (pneumonia).

| Respiratory health

In selecting a milk powder, the essence is the growth and health of the youngest calves. For the past three years, dairy farmers have also been able to select a milk powder that contributes to airway health: CAIR. 'With Kalvolac CAIR, the calf has 33% fewer problems involving airway infections'.

| Hygiene

In this article we will focus on the importance of hygiene in calf rearing. Nina Hennes, our R&D colleague will share her expertise on this topic. "It starts at the immediate birth of the calf. As you know, calves are born without an innate immune system, which means that calves are very vulnerable".

| Colostrum

Good-quality colostrum contains antibodies in the form of immunoglobulins, abbreviated to IgGs. Thanks to their ‘life history’, older cows deliver better-quality colostrum. But the antibodies are not the only elements that make colostrum a unique product.

| Respiratory health

Alongside diarrhea, airway infections are the most common disorders affecting calves. And you all know what that means. Sick calves cost you money and valuable time. They also have disturbing consequences for your herd and as a result for your farm. Prevention is better than cure. Tips based on the experience of fellow dairy farmers across the Netherlands may therefore prove valuable.

We have selected the ten most commonly submitted tips and are happy to share them with you.
