The rearing of dairy calves in groups is rapidly replacing the once common practice of raising the calves individually. Some farms have chosen to raise the calves in small groups. Group housed calves are fed by bucket or a small container that may or may not have teats. In larger groups (25-30 calves) the easiest way to feed the calves in ad libitum from a container with a teat or from automatic feeders, as computerized feeding systems are becoming quite popular. There are some negative consequences associated with feeding the calves ad libitum. One problem is the decreased growth performance after weaning, as giving the calves ad libitum access to milk tend to decrease the amount of concentrate they eat, thus the conversion from a liquid to solid diet after weaning is much more difficult. Also when feeding the calves ad libitum there is an increase in the cost of feeding due to the higher amounts of milk consumption. Another problem associated with the group housing of calves is the increased chance of contacting an infectious agent, thus promoting infection in these calves. According to a survey of farms, respiratory disease in becoming an increasingly common problem in calves housed in groups, fed from a computerized feeding system. Little research has been conducted on the housing of calves in large groups, so there are many questions that are yet to be answered. Producers are wondering how to prevent larger calves from disturbing the smaller calves in the group when they are at the feeder. Another area in which more research needs to be conducted is at what age and by what method should the calves be introduced to the feeding system. Finally producers want to know how to detect if an animal is ill based on the feed intake records generated from a computerized feeding system. Thus, there is a need for more research to be done in this novel form of dairy calf management.
