The effect of housing calves and pairs and flooring on growth and rest behaviours of one week old calves was examined. The calves were housed individually or in pairs on concrete floors or were housed individually with rubber mats on the floors for 20 weeks. All treatments were provided with wood shavings for bedding. The total daily duration, bout frequency and mean duration of total resting, resting on the side or resting on the stomach were noted through video recordings taken at 2, 4, 6, 7, 11, 14 and 21 weeks of age. The effect of time of day was analyzed on week 4, 7, 14 and 21. Mean daily growth was positively correlated with the total time the calves spent resting over the 20-week experimental period. As the calves grew older, the amount of time they spent resting remained the same, however the amount of time they spent resting on their side decreased. The time spent resting around feeding decreased after solid feed was introduced. Housing didn’t affect daily growth or resting behaviour. The daily duration and bout frequency for resting on the side was higher in pairs than individuals (both housed on concrete). There was also no difference in growth or resting behaviour between calves housed on concrete or on rubber mats. However, the provision of wood shavings may have made the concrete flooring comfortable. Adequate rest is needed to maximize growth and the longer a calf rests, the better it will grow. Housing calves in pairs provided them with more space, and they were observed resting on their side more often and for longer.
