[Using the computer in processing data on reproduction in dairy herds (author's transl)]

A computer program is described, by which data on reproduction (data on calving, oestrus and insemination, pregnancy diagnosis) in dairy herds may be processed. This program is designed to supply dairy farmers with information facilitating herd management. Thus, each month the famer is sent an advisory list stating which cows should be inseminated, which should be dried off and which can be expected to calve. In addition, he will receive an annual report on the fertility of his herd. Among others, the following items are listed: the pregnancy rate after the first insemination, the interval between parturition and first insemination, the interval between parturition and conception and the number of cows disposed of because of failure to conceive. The intention is to test this computer program for efficiency on 500 dairy cattle farms.
