Objective:

To analyze the results of the management of grazing sows at international scale, as well as the elements of waste in field and confinement, which contribute to the resilience of pig husbandry systems.

Materials and Methods:

The results of more than 80 publications about the elements of the management of grazing sows: main grazing systems, se of plant genetic resources in their feeding under different climate conditions, stocking rate, quality of the ration, breed, category, as well as waste recycling, applicable to the conditions of the tropic, were analyzed.

Results:

There is innovative evidence in the management of grazing sows with the use of different plant genetic resources, in systems that go from subsistence to intensive management with electrical fence. The conditions or requisites for management, effect of stocking rate, species, importance of the nutritional value and animal category (mainly with sows), recycling in grazing and semi-confinement (deep litter), are analyzed.

Conclusions:

Pig feeding based on pastures and forages, mainly, implies different management, with different solutions from the ones that are applied in conventional confined systems with concentrate feeds. The agroecological management and use of adequate plant genetic resources are the ways for resilient and sustainable production in the face of climate change, which contributes to food sovereignty.
