Cattle adaptations to different husbandry systems

Abstract

Calves from a dairy breed (Friesian) and a French « hardy breed (Salers) were compared in different rearing conditions (including artificial feeding vs. suckling) and at various ages. Animals from the two breeds were not different when reared by cows. Significant differences occurred when they were in a artificial rearing system. Friesian calves were more active than Salers at birth, drank milk more easily from a bucket, ate more feed and had a higher growth rate. Puberty occurred earlier in Friesians than in Salers. These results may be the consequence of adaptations differences to different husbandry systems. « Hardiness » seems to be a too general word to usefully describe these characteristics.
