Unlock the full potential of your calves

A lactation begins at calving. However, before a lactation can begin, development of the mammary gland must occur, and this development begins long before the pregnancy that actually initiates lactation.

The development of the mammary gland is not the only factor affecting milk production; it is also impacted by feed efficiency and hormonal regulation, among other metabolic influences. Just as mammary gland development begins in early life, feed efficiency and hormonal regulation also are being programmed from as early as within the womb.

As dairy producers, you have a window of opportunity to influence this early life development toward positive lifetime performance.

At Trouw Nutrition, we have a strong focus on young animal research, and we have partnered with research institutes and universities to compile the scientific evidence that demonstrates the benefits of early life nutrition.

With LifeStart, we aim to connect the science with applicable feeding programs and management recommendations that ultimately can improve profitability on your farm by helping calves to develop faster and grow into healthy, productive cows.

The early life window of opportunity

feed efficiency, feed costs


As this table demonstrates (from a study by Bach and Ahedo in 2008), the younger it is, the more the calf will effectively convert its feed into weight gain, up to 180 days. It is therefore a critical period where it pays to invest in feed that will support the optimal development of its future dairy characteristics.

Optivia® products have been developed using the LifeStart scientific foundations to provide you with practical on-farm application solutions to maximize the profitability of your herd replacement program.

Rumimax®; a Unique Feed for the Critical First 2-4 Months

The weaning process is one of the most significant changes in the absorption and use of nutrients in a dairy animal’s life.

With Rumimax®, the objective is to keep a consistent intake of nutrients: when calves transition from milk and starter to Rumimax®, they still have a high concentrated dry ration which promotes higher intakes.

This unique and easy-to-use product allows you to prepare the ration in advance, and offer it to calves at will, reducing the management quantities and feedings.

Optivia® Rumimax® is part of a complete program based on scientific data. The Science behind LifeStart sets life performance through:

  • Good colostrum management
  • A sufficient quantity of milk over time
  • Good solid feed, integrated into weaning stages and favouring an optimal development of the rumen
  • A good post-weaning strategy
  • Care and management adapted to early life
  • Adequate facilities
  • Vaccination programs for lactating cows and dry cows
