Calves on a dairy farm were being fed with gang feeders - six nipples on each one with no internal dividers. Two feeders per pen of ten calves were filled twice daily with 3 liters of milk replacer per calf.
The calves were not gaining well, scours treatment rate was acceptable but the treatment rate for pneumonia was over fifty percent during the eight weeks the calves were in this pen.
In order to improve the situation the automatic feeder was installed. The high pneumonia treatment rate continued as well as the low growth rates.
