The objectives of this study were as follows: 1) to determine the nature of the seasonal pattern and to select an appropriate method to obtain a reliable index of seasonal variation in the production of eggs; 2) to test the reliability of the indexes by use of charts and the index of irregularity; and 3) to demonstrate the use of the indexes in forecasting egg production. The data for this report was obtained from two publications of the South Dakota Crop and Livestock Reporting Service, Sioux Falls, South Dakota: South Dakota Poultry Production and Marketing, 1951 and 1957, and South Dakota Agriculture, 1958. From the information presented in this paper, three conclusions can be drawn about the seasonal pattern for egg production. Secondly, the pattern has been gradually changing in the last ten years; the seasonal variation in egg production is gradually leveling off. Thirdly, because of this changing seasonal pattern, the method of ration-to-moving average with graphical determination of the trend lines and indexes computed for every year may be used in determining the index for egg production for South Dakota unless the seasonal pattern levels off and becomes constant.
