Relating goat milk production according to the Normalized Difference Vegetation Index and precipitations in the Chaco forest throughout the 2016-2018 period

This work aimed to quantify and relate goat milk production and the Normalized Difference of Vegetation Index of the semiarid Chaco forest and the monthly average precipitation along the 2016-2018 period. The work was carried out in El Polear, in Santiago del Estero, Argentina. Even though the NDVI...

The work was carried out in El Polear, in Santiago del Estero, Argentina. Even though the NDVI of the forest and its lower strata biomass productivity were affected by drought, its milk production curve remained unaffected.

Significant straight relationships (p<0.05) were found between the average goat milk production and the average monthly precipitation (r=0.64) as well as the NDVI and the semiarid Chaco forest (r=0.59). The resulting linear models involving goat milk production with both precipitation and NDVI had moderate and significant (p<0.05) explaining power (R2=0.41) and (R2=0.35), respectively.

El objetivo de este trabajo fue cuantificar y relacionar la producción de leche caprina con el Índice de Vegetación de Diferencia Normalizada del Bosque Chaqueño semiárido y la precipitación media mensual en el periodo 2016-2018. El estudio fue realizado en El Polear, Santiago del Estero, Argentina. El NDVI del bosque y la productividad de biomasa de sus estratos inferiores fueron afectados por sequía. La curva de producción de leche no fue afectada por la sequía, y se debe a la estabilidad del bosque con leñosas de raíces profundas, a los estratégicos desplazamiento de fenofases de los estratos inferiores del bosque (latifoliadas y herbáceas) en épocas de sequía y a la adaptación a cambios en la selectividad de la dieta de los caprinos ante fluctuaciones de forraje. Los picos de NDVI de invierno deberían ser considerados para nuevas líneas de investigación sobre el aporte de los mismos a las reservas energéticas del componente caprino ante la entrada del invierno. Significativas relaciones directas (p<0.05) fueron encontradas entre la producción media de leche caprina y la precipitación media mensual (r=0.64) y entre el NDVI del Bosque Chaqueño semiárido (r=0.59). Los modelos lineales resultantes, entre la producción de Leche caprina con la Precipitación y el NDVI tuvieron, respectivamente, moderado y significativo (p<0.05) poder explicativo (R2=0.41) y (R2=0.35). Los modelos lineales obtenidos posibilitan predecir la producción de leche estacional facilitando la planificación y toma de decisión tanto a productores como a la agroindustria.
