The following taken from the introduction: "It may be argued that a dairy farmer who is testing his cows every year and breeding his own replacement heifers, sired by pedigree dairy bulls with reasonable butterfat backing, should by a programme of intelligent culling, be able to establish and maintain a herd consisting mainly of mature cows of high producing ability. This is the point that this study endeavours to answer."enThe AuthorDairy herd testingThesisQ111965030https://www.wikidata.org/wiki/Q111965030
