Adoption of an Artificial Insemination System (A.I.S.) by 99 dairy farmers of Máfil Country in the province of Valdivia was studied. This study included two consecutive periods, the 1970-1971 reproductive period and the 1971-1972 one. Three groups of farmers were considered according to the practice adopted: (1) Those who used the A.I.S. during the two periods studied (Adopters, 14%); (2) Those who used it once, but quitted (Retractors, 15%), and (3) Those who never used the A.I.S. (Non adopters, 71%).
The analysis of some socio-economic characteristics of the three groups, determined that Adopters owned the largest farms, the largest number of cows, had high educational and economic levels and most of them had german background. All of them participated in some formal organization and had high scores in technical agricultural reading and dairy technology adoption indexes.
