 The Guaná provided Mbayá chiefs with labor, agricultural products, textiles, and wives and in exchange were given protection and European goods such as iron tools by the Mbayá.The cultures of the Guaná and Mbayá slowly became more similar as the Mbayá adopted agriculture and weaving and the Guaná became equestrian.The Mbayá augmented their numbers, strictly limited by late marriages and abortion, by intermarriage with Guaná and captive women of other ethnic groups.
