THE first part is a review of the usual methods for progeny testing, measures of yield improvement, and the most common sources of variability. The special part deals with the results obtained by some of these methods on three Ostland bulls, a father and his 2 sons. Progeny testing was carried out by means of Hansson-Yapp's index and with the use of the daughter mean for milk-yield in kg., fat %, and butter-fat yield in kg.
