Summary

A sample of 6846 Friesian heifers recorded in 672 herds during the year ending 30 September 1968, taken from two areas of England and Wales, has been used to estimate the effect of the calving month on total lactation yield. In both areas, the North and the South-West, a variation amounting to nearly 12% of the mean yield was estab-lished, with lactations resulting from October-December calvings the highest and those from May-June calvings the lowest. There was no evidence of association with particular levels of management, or management systems, as exemplified by a seasonal calving pattern.
