A lump of what?

The article features dairy farmers Tony and Sue McDonnell of Milton, New Zealand, who sharemilked for Ewing Farms, which eventually financed them into buying the property in 1996. They then bought the second farm, Haddington Farms, from Tony's mother. According to Tony, despite their herd's 100 percent recorded ancestry, their record-keeping habits are the same with those of other farmers. As of June 2010, they have 23 contract matings with Livestock Improvement Corporation (LIC) for next season.
