Hydro-environmental assesment and grazing capacityvaloration by thermo-pluviometrics indicators
For a sustainable management of grazing lands, is necessary to know the strategy of nature to sustain the grassland,in consequence, the management schemes must be based in programs related to an environmental characterizationand adequate monitoring. With the aim to develop a tool to support the diagnosis of grasslands, we hereby proposethe application of the Hydro-Environmental Availability Index (HEAI), with scale from 0 to 10. According to theapplication of HEAI in 36 localities of Sonora, Mexico, five of them (13.9 %) fluctuated from 0 to 2.5, in consequence,their grasslands are highly vulnerable to drought, with very low possibilities for management. Twenty (55.6 %)oscillated from 2.5 to 5, suggesting a management with severe restrictions. Eleven (30.5 %) fluctuated from 5 to 7.5,proposing a sustainable management with adequate rotations and preventions during a drought, and none of localitiesreached values for HEAI > 7.5, high potential for sustainable management, with appropriate rotations. It must beconsidered that the actions to prevent the effects of overgrazing, not always are enough to mitigate the overwhelmingconsequences of droughts, which are exacerbated by climate change.

El objetivo del estudio fue evaluar los efectos de línea genética (LG), número de parto (NP) y sala de parto (S) en el tamaño de la camada nacida viva (TCNV), el número de lechones nacidos muertos por camada (LNM), el tamaño de la camada al nacimiento (TCN) y al destete (TCD), los pesos de la camada al nacimiento (PCN) y al destete (PCD), el consumo diario de alimento de la cerda (CDA) y las pérdidas de peso (PPL) y grasa dorsal (PGD) de la cerda en la lactancia. Además de los efectos fijos LG, NP y S, el modelo incluyó las covariables TCN para PCN y TCD para PCD. Se encontraron diferencias (P<0.0026) entre LG para TCN, TCNV, LNM y CDA. El NP sólo fue significativo (P<0.0001) para CDA, S sólo lo fue (P<0.0380) para LNM. Las cerdas de tres o más partos tuvieron mayor CDA (4.5 ± 0.2 kg) que las de primero o segundo partos (3.4 ± 0.2 kg). Se requiere reforzar la atención al parto y durante la lactanciapara reducir la muerte de lechones al parto y en la lactancia; así como evitar que la cerda pierda demasiado peso y grasa dorsal con el fin de reducir el deterioro del comportamiento productivo y reproductivo postdestete.
