LifeStart sets life performance

Only 1 chance for a good start!

The first few weeks of a calf’s life are crucial for its future. With a LifeStart calf rearing program with a higher plane of nutrition during this critical period, dairy calves will not only grow better, resulting in earlier breeding, they will also produce more milk with a reduced risk of culling during 1st and 2nd lactation.

How can a farm improve the life time performance of their cows with the LifeStart program for calves?

Dairy farming can be made more sustainable by producing more milk with less animals. Particularly the number of young-stock per lactating cow should go down. By utilising the full potential of each dairy cow, a farm can maximise the average lifetime daily production of the animal. The aim of each farm should be to:

  • Reduce the age at which a heifer calves for the first time
  • Increase the milk production per lactation
  • Increase the number of lactations per cow

Benefit from the main 5 deliverables of a LifeStart programme and make your calf rearing objectives become a reality

A higher average daily weight gain

Improved udder development

A younger age at first breeding

Higher milk production

A lower culling rate during first and second lactation

Go for optimal performance
with a LifeStart feeding programme

The importance of a LifeStart feeding schedule is clear, but what exactly is required to achieve a LifeStart performance? A LifeStart feeding schedule consist of a number of elements addressing the challenges in different life stages in which calves will evolve to become highly productive dairy cows.

Check out each step in which you can influence and optimise the development of your calf.

More about the LifeStart feeding schedule

A LifeStart programme will result in a higher average daily gain during the pre-weaning phase

The quality of early life nutrition has a strong influence on gene expression, which in term is an important factor influencing maximum growth and future production potential of dairy calves. LifeStart feeding schedules for calves can result in an increase of average daily gain of up to 300 g/day [1,2,3,4,5,6,7,8,9,10]

The TN Kempenshof trial [11]

A LifeStart group was fed 8 litres per day compared to 4 litres per day for a control group. Both groups were fed at a concentration of 150 g/l.

Results

Calves in the LifeStart group had a higher bodyweight from day 7 onwards.

A LifeStart programme can double the amount of udder tissue

The development of udder tissue at a young age is essential for optimal milk production of a cow later in life. Several studies [14,15,16]., including the TN Kempenshof trial[17] resulted in compelling evidence that growth in the first eight weeks of life is a key factor in the optimal development of udder parenchyma that forms the milk producing glands.

A LifeStart programme will result in an

First insemination 399 days 393 days

Age at first calving 699 days 684 days

Fertility in heifers on a LifeStart feeding schedule compared to heifers reared on a restricted feeding schedule.

Several authors have shown that calves on LifeStart feeding schedules reach puberty at an earlier age and can be inseminated earlier [6,10,12,13].

The TN Kempenshof trial [11]

Calves in the LifeStart were inseminated earlier and calved at a younger age.

A LifeStart programme will result in
a higher milk production

There is an overwhelming amount of evidence that increased levels of nutrition in dairy calves during the pre-weaning phase lead to an increase of future performance. A LifeStart programme will result in an additional milk production during the first lactation of at least 300 litres.[1,2,,4,5,6,7,8,9,10], but often much more [18].

The TN Kempenshof trial

Holstein dairy heifers in the LifeStart group produced 400 litres extra fat and protein corrected milk compared to the controls.

A LifeStart programme will reduce the culling rate

Culling rates in LifeStart heifers compared to controls reared on a restricted feeding schedule.

A LifeStart feeding schedule can potentially reduce the culling rate in first and second lactation dramatically{2,10].

The TN Kempenshof trial

During the TN Kempenshof trial, there was no significant difference in the number of heifers calving for the 1st time. Once milk production started however, there was a significant difference in culling rate with more LifeStart cows completing their 2nd lactation.
 
 
 
 
Reaching 1st calving P=0.36 (93% vs 88%)
Completing 1st lactation P=0.07 (77% vs 64%)
Completing 2nd lactation P=0.05 (56% vs 39%)

Increasing average lifetime daily yield with the LifeStart calf rearing programme

LifeStart research has shown that a LifeStart feeding schedule for dairy calves with elevated planes of nutrition during the first weeks of life has a big impact on future growth and organ development of a dairy calf. This will result in a better performance later in life.
