A.S. Series 79-21
A computerized flock record keeping system has been in use at South Dakota State University since 1965. A report is computed and published monthly from data received from flockowners. The project started with a few flocks and expanded to 67 in 1972. However, in the spring of 1975, participation dropped to about 30 flockowners and has continued to drop down to a current level of about 15. The records of those flocks completing their laying cycle during the calendar years of 1969 through 1978 are summarized in Tables 1 and 2.
