Abstract
Grass intake and meat oxidative status of geese reared in three different agroforestry systems
Highlights
The Global Forest Resources Assessment (FAO, 2016) highlighted a significant reduction of the world forest area with the loss of 129 million of hectares between 1990 and 2015
The estimation of grass intake showed that the geese belonging to the apple orchard (AO) and olives trees (OT) systems ingested a higher quantity of grass respect to the V group (Figure 1)
The polyunsaturated fatty acids (PUFA) profile showed the same trend in both muscles: the n-6 PUFA did not show any significant differences among the groups, while the n-3 PUFA were higher in AO and OT, followed by V and C
Summary
The Global Forest Resources Assessment (FAO, 2016) highlighted a significant reduction of the world forest area with the loss of 129 million of hectares between 1990 and 2015. In Italy, orchards (mainly olive trees) are located on marginal land: the sloping terrain, the altitude and the difficulty of mechanization render about 1 million hectares of olive trees at risk of abandonment (Rosati et al, 2012) Such a state of affairs has caused a degradation of the terrain, which in turn has intensified the hydrogeological instability and has increased the risk of fire episodes, especially in the period between 2008 and 2017 (San-Miguel-Ayanz et al, 2017). In this scenario, it is necessary to minimize the environmental impact on crop and animal productions (De Boer et al, 2011) by improving the agro-food sustainability, recovering and valorising the byproducts and wastes (Tinello et al, 2017), preserving biodiversity (Bach et al, 2020), increasing animal welfare (Broom, 2019) and reducing water footprint of agricultural practices (Cosentino et al, 2015). In order to solve these environmental problems, the European Commission has developed
