This is a couple exerpts from some tests that were being conducted years ago. Pay attention to the bottoms:
The eight purchased Polled Hereford foundation females (three of which were the product of sire X daughter matings) were all sired by Numode 2 (4323704). Numode 2, an outcross bull out of Quester's Queen 2 (3545308), was a grandson of Plata Domino 36 (3093731). Additionally, CARF Sears Loboy O10 (6691376), the first sire used in this line, was out of one of the foundation cows (Lomaid D Sal (5265805)) and Numode 2. The Bonanza line, created by mating inbred half-sibs, produced its first calf crop in 1953. A total of 61 calves, with an average inbreeding of 38% were produced over the 12 year period this line was in existence. Five different sires were used before the line was discontinued in 1964 due to the occurrence of dwarfism.
The six Polled Hereford foundation females of the Animas line, purchased from a Nebraska breeder, were the product of mating President Mischief (3030144) to his daughters. The two foundation sires, FLR President Mischief (6392011) and FLR President Mischief 80 (6834047) resulted from similar matings. The initial mating scheme involved the mating of full- and half-sibs. Four calf crops, produced at the station in 1953-55 and 1958, weaned 24 calves with an average inbreeding of 38%. The Animas line was discontinued in 1958 as it became evident that the performance of this line was below that of other lines already in the herd.
