Evolution of milk production systems in tropical Latin America and its interrelationship with markets: an analysis of the Colombian case por Holmann, Federico J., Rivas Ríos, Libardo, Carulla, J., Rivera, B., Giraldo, L., Guzmán, S., Martínez, M., Medina, A., Farrow, Andrew

“…The survey was designed to quantify inputs and products in order to determine costs and prices at the farm level in order to calculate (a) variable costs for feed supplementation, labor, health, reproduction, fertilization, and irrigation; (b) gross income from the sale of milk and beef, and (c) to characterize farms according to productivity level and management practices. The statistical analysis of multiple correspondence and general linear models were used to explain the variability observed between productivity and profitability as a function of technological change. …”
