A.S. Series 75-40
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. We have usually had 50 to 60 flockowners reporting data. However, in the spring of 1975, participation dropped to about 30 flockowners. The records of those flocks completing their laying cycle during the calendar years of 1969, 1970, 1971, 1972, 1973, 1974 and through June of 1975 are summarized in table 1.
