Computer controlled calf rearing

摘要

The main objective of using computer controlled calf feeders is to save on labour and to avoid digestive problems by giving calves an homogenous drink several times a day. However, there are still major problems connected with this technique, namely:hygiene; health control; and accuracy of milk allocation. A newly developed calf feeder is now able to improve hygiene by automatically rinsing with detergents, including all parts which are in contact with milk. Feeders can also be equipped with a flexible teat which can be disinfected after each visit of calves. To control the individual milk consumption of calves, a float in the mixing bowl measures the amount of prepared and consumed milk. The float is a transsonar distance sensor which is also able to monitor the drinking speed of each calf. All data is sampled and gives detailed feedback about the state of health of the calves.
