On any sized dairy operation there are a multitude of events occurring from the time a calf is born until she leaves the herd. Software programs are available to help manage this task of recording events. The bottom line is no matter how good someone’s memory is it is no substitute for having historic information on animals of all ages that can be easily accessed. However, the information is only as good as the person entering the data and is useful only if someone is monitoring the events.

The benefits of corn silage kernel processing have been replicated many times in research and at the farm level. The main advantage is breaking the corn kernels into pieces, which should result in improved starch utilization and milk production.
