The second phase depends on the results of analysis of the sets of breeds in the first phase and entails the choice of breeds for conservation, utilisation or development low genetic distances among a set indicates little between-breed diversity and close relationship between the breeds in the set, while the reverse is true for high genetic. The local brazilian pig breed piau is a lard-type pig that has undergone a breeding and selection process devised by the veterinarian antonio teixeira vianna in 1939 the objective of the program was to develop a dual purpose animal, that is an animal suitable for the production of both fat and meat the main characteristics of the piau breed are rusticity, adaptability and high disease. Breeds for conservation, deciding whether genetic or al- lelic diversity should be considered depends on whether the focus is on short-term (eg avoiding inbreeding in.
