“…We analysed the functioning of livestock systems from the perspective of nutrient cycles, by quantifying material flows between fodder resources (cropland and grassland), livestock, and the natural environment. This allowed us to discuss different productive and environmental indicators (Bonaudo et al, 2015;Gameiro et al, 2019). We used the GRAFS methodology (Generic Representation of Agro-Food Systems) to produce a biochemical representation of our system (Billen et al, 2014(Billen et al, , 2015Lassaletta et al, 2014).…”

“…For cattle, we considered that grazing provides the whole diet (Oliveira Miranda, 2016). For monogastric animals, we considered that rations are composed of corn and soybeans (Gameiro et al, 2019). Crop production was converted from kilograms of fresh matter to kilograms of N, based on the coefficients of fixed N in products (Lassaletta et al, 2014 andFAO, 2001) (Table 3).…”

The rational use of nutrients is a key factor for the sustainability of agricultural systems. This study aimed to analyze the nitrogen balance and use efficiency, and the valorization of organic residues in integrated systems, in comparison to conventional agricultural and livestock systems. The experiment was assembled in a randomized blocks design with three replicates. Six production systems were compared, grain maize production (CROP) and pasture for beef cattle production (LS), and four ICLS (Integrated Crop-Livestock System) for grain maize production and pastures for beef cattle. In order to estimate the nutrient balance, all inputs and outputs at farm levels were considered, and in view of the results obtained for nutrient balance, the nutrient use efficiency was calculated. The CROP system presented higher nutrient use efficiency, but at the same time, it resulted in negative contributions for the nutrient balance lower amounts of nitrogen in the organic residues and lower valuation. The LS and ICLS provided a higher amount the N and valuation of organic residues. The presence of components such as pastures and the animal contribute in a positive production system, while reducing the needs for chemical fertilizers.

In livestock, biosecurity, animal welfare and meat quality have a synergetic effect on the final product. To meet minimal safety and humane production, it is necessary to consider biosecurity risks and procedures to mitigate animal welfare problems. Following guidelines to achieve it, the meat quality improves consequently. Here we tested two parameters regarding the meat quality of beef cattle to understand how the poor inspection affects the quality of the final product. Therefore, 12 samples of the longissimus dorsi muscle were evaluated from different butcheries, using fresh meat recently received by the supplier. There were no sanitary inspection records related to the sampled meat. The results showed a large percentage of PSE (pale, soft, and exudative) and DFD (dark, firm, and dry) meats. Given the pH and color values, it is concluded that the slaughtering was not carried out properly. Hence, technological defects in the meat were observed, making it inappropriate for consumption. We concluded that inefficient pre-slaughter handling is compromising animal welfare, increasing the biosecurity risk, and impairing the quality of the final product. We argue that these problems not only decrease the sustainability of livestock systems, but also compromises human health. Currently, livestock plays an important role in global environmental concerns, such as climate change, land degradation, water pollution and biodiversity loss. Then, it is needed to reduce the waste of such products.
