Select well-adapted species and breeds
Many organic farmers report switching breeds in conjunction with transitioning to organic. Older dairy breeds such as the Dexter, Dutch Belted and Ayrshire are gaining renewed interest among organic dairy people looking for traits like longevity, hardiness, thriftiness and willingness to graze. Organic pig farmers favor breeds that show good mothering characteristics, and often choose colored breeds for pasture-based systems (since white breeds can suffer from sunburn).
Crossbreeding is also popular with organic producers, taking advantage of hybrid vigor. Many an organic herd is made up of a colorful mixture of crossbred Jersey, Brown Swiss, Guernsey and others. Some organic farmers report success importing Holstein semen from New Zealand, where virtually all dairies are grass-based and animals are selected for success on a grass diet.
Within most breeds, there will be individuals with the characteristics necessary for sound organic livestock production. The challenge lies in knowing what phenotypic traits to look for. Animal frame size, eating preferences and reproductive traits can all be favored through breed selection. Culling individuals with recurrent problems and selecting individuals that thrive under the conditions you wish to establish will gradually build up the genetics you need.
