LifeStart feeding schedules lead to extra growth during the pre-weaning phase
Research has shown that the quality of nutrition has a strong influence on gene expression, which in term is an important factor influencing maximum growth and future production potential of calves.
Several authors have studied the effect of elevated planes of nutrition on average daily weight gain during the pre-weaning phase and the effect on future productivity [1,2,3,4,5,6,7,8,9].
The milk-feeding programmes as well as colostrum management and other rearing conditions varied between these studies, so the effect on pre-weaning average daily gain and subsequent milk production varied as well.

The Trouw Nutrition Kempenshof trial
A total 86 individually housed female calves were included in a longitudinal study carried out in the Kempenshof.
Pairs were fed the same amounts of colostrum from the same source and blocked by colostrum, parity and season. They had ad libitum access from day 4 onwards to water, starter feed and straw and were all weaned according to a standard protocol at 56 days of age. From day 70 onwards, they were moved to group housing. The only difference between the two groups was the amount of calf milk replacer fed. The LifeStart group was fed 8 litres per day compared to 4 litres per day for the controls, both groups were fed at a concentration of 150 g/l.
Calves in the LifeStart group had a higher bodyweight from day 7 onwards (see figure 1). At weaning, the difference in ADG was 155 gram, at day 70, the difference in ADG between the LifeStart group and the controls was 123 gram.
