Abstract:
Concern about welfare and behavioural needs of animals has increased the interest in keeping calf and cow together after parturition. In this experiment six calves suckled their dams twice a day for five weeks then once a day for three weeks (DAM8). Six calves (DAM5) suckled during five weeks in the same way as calves in DAM8 and were then abruptly weaned. Six calves (TEAT8) were fed the same amount of milk from teat buckets as DAM8. Consumption of dry feed by all calves was low at the age of five weeks. Consequently, the calves abruptly weaned at the age of five weeks lost weight after weaning. Nursing times were quite similar (about 20 min) during the entire suckling period. However, reducing suckling from twice a day to once a day at the age of five weeks increased the frequency of teat changing. In conclusion, total weaning at the age of five weeks from high milk allowance seems not recommendable. Five weeks of twice a day suckling followed by three weeks of once a day suckling is likely to reduce the decline in energy intake and growth following weaning.
