The purpose of this research was to investigate the possibility of the reducing weaning age of Brown Swiss x Eastern
Anatolian Red F1
crossbred calves reared in North East Region of Anatolia. A total of 26 calves were housed in individual
hutches and weaned at 2 (early weaning) or 3 (late weaning) months of age. While weaning weight of the calves in
different weaning age treatment groups was significantly (P<0.01) different in favor of calves weaned lately, 6 months
weight was not significantly affected by ages of weaning. Average 6 months weight of the male calves was significantly
(P<0.05) higher than that of female calves. The effects of weaning ages on the weight gain in both post-weaning and
overall periods of the trial were not significant. Total milk dry matter intake (DMI) of the late weaned calves were
significantly (P<0.01) greater than that of early weaned calves. However, starter DMI of the calves weaned 2 months
of age was higher (P<0.05) than that of late weaned calves, but dry hay and total feed DMI were not affected by the
weaning ages. Sex of the calves also did not result in significant effects on the milk, dry hay, starters and total feed DMI.
Feed conversion efficiency in a period between birth and 6 months of age were not significantly affected by weaning
ages. The weaning age and sex of calves did not significantly affect the gains in body measurements. Percentage of time
spent for lying, standing, eating and drinking water behaviors were not also significantly affected by both weaning ages
and sex of calves. The results of this study suggested that the crossbred calves could be weaned successfully at 2 months
of age without having adverse effect on their growth, feed conversion efficiency and behavioral traits.
