Two solutions for feeding milk in liquid form only are the DeLaval calf feeder CF300A and CF200+ units. These machines do not have powder hoppers. The milk is stored in a container with a stirring and possibly cooling device. The milk can either be fresh or sour. If milk replacer is to be fed, it has to be prepared with other mixing equipment or by hand.

The milk is prepared in the same way as in the combi. The milk is heated by a heat exchanger and distributed in small 0.5 litre portions to the calves.

Working principle for fresh milk machine.
The unit enables small investments and can be upgraded to a combi machine at a later stage. For large installations with more than 80 calves, to be fed with both fresh milk and powdered milk, it may be more economical to install 1 powder and 1 fresh milk machine instead of 2 combies.

A cold sour storage feeder has in recent years been the first step in simplifying milk supply for group keeping. The milk is made sour with acids or living cultures. It can be consumed cold and is mixed several days in advance.
The real aim of this procedure, to regulate intake via pH value and the milk temperature, only succeeds under certain conditions.
DeLaval calf feeder CF100 is a complete feeding unit with feeder, processor, milk storage container with agitator, heat exchanger, and feed station with rails. The rations are based on weight and the milk storage container stands on a scale and feeds the calves with the exact amount of milk at the correct time.
The storage container is connected to the drinking station, via a heat exchanger (optional) by a tube. The calves are fed with exactly the right amount, as controlled by the scale and the feed processor, which has several key features.
The processor is placed ‘on-board’ the feeder, to provide a good overview of the calves when programming. The program is translated into many languages and is very easy to use. Different feeding options are available, such as automatic increase and decrease of the feed portions (feed plans) and feeding of concentrate.
The unit is basically designed for sour milk, but sweet milk and powder milk can also be used. The sweet and powdered milk must be heated to 30 – 35 °C. The powder milk has to be prepared by hand in advance and the cleaning of the unit must be done daily. The unit can easily be updated with a feeder for concentrate.
