Calves included in the Kempenshof trial had an improved growth as a result of a LifeStart feeding schedule


Key takeaways from the research

  • The Kempenshof LifeStart trial compares a LifeStart feeding schedule with a restricted feeding schedule

  • The aim of the trial is to follow animals up to the end of their productive lives

  • LifeStart feeding schedules result in an increase in ADG


An intensive feeding schedule in dairy calves improves growth compared to restricted feeding

The quality of early life nutrition in dairy calves has a strong influence on gene expression, which in term is an important factor influencing average pre-weaning daily gain and future milk production of heifers[1,2,3,4,5,6,7,8]. Rearing conditions, colostrum feeding and amounts and type of milk fed in these trials varied considerably. In 2014, TN started a longitudinal, carried out in the TN dairy research centre the Kempenshof[9], a study which is still continuing today. The aim of the study is to follow the calves included during their entire productive life.

Study design

Pairs of female Holstein dairy calves were fed the same amounts of colostrum from the same source and blocked by colostrum, parity and season. A total of 86 calves were included in the study. They had ad libitum access to water, starter feed and straw from day 4 onwards 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 body weight from day 7 onwards (see figure 1). At weaning, the difference in ADG was 155 grams, at day 70, the difference in ADG between the LifeStart group and the controls was 123 grams.



The results of this study are in line with the findings of many other researchers, who found that elevated planes of nutrition increase average daily gain.
