HUELLA HÍDRICA Y PARÁMETROS PRODUCTIVOS EN GANADERÍA DE LECHE DE BOYACÁ, COLOMBIA
Abstract
In recent decades, water use in livestock production has been a relevant issue in the discussion on sustainable food systems and competition for water resources. This research analyzed the relationship between productive efficiency, stocking rate and water footprint in primary milk production in high mountain farms in the central zone of the department of Boyacá. A quantitative and correlational study was carried out in 50 livestock systems whose main objective is milk production. The following parameters were calculated: percentage of milking females, production per area, per year and per female, and stocking rate. The water footprint was estimated and divided into three categories: blue, green and gray. The data were processed with Rstudio, Shapiro-Wilk test, eSpearman correlation coefficient and multiple linear regression analysis were performed. Total HH (x̅ 10.12 m3/L), HA (x̅ 0.01m3/L), HV (x̅ 1.99 m3/L) and HG (x̅ 8.13 m3/L) were identified as results. The variables Porhembras, ProductKg/Female/Year and ProductKg/Ha/Year show the highest correlation coefficients, being stronger with HA. The potential for improving the environmental sustainability of dairy production through the adoption of efficient practices, especially in the animal component, is evident.
