Abstract: The objective of this study was to evaluate the effect of reducing dietary nutrient content for pigs from 25 to 130 kg live weight, on performance, carcass traits, meat quality and environmental impact. Forty gilts and 40 barrows were distributed in a randomized block design with two treatments and 10 replications per treatment, with four animals per experimental unit. The feeding program was in four phases. Two diets were formulated for each feeding phase. One was adjusted using the InraPorc® model to minimize crude protein, amino acid and phosphorus excess (LN), and the other (ST) was formulated with standard Brazilian recommendations. No differences were found on performance. The mean ADG and ADFI were 0.919 and 2.46 kg/day, respectively. Carcass characteristics and meat quality were also not affected by the experimental diets. The average total feed cost was 6.8% lower (P < 0.05) for animals fed the LN diets. For nitrogen and phosphorus balance, there was no statistical difference in retention, but the nitrogen and phosphorus intake were 15.8% and 9.42% lower for pigs fed LN diets, respectively, and the excretion levels were 24.1% and 14.6% lower for pigs fed LN diets, respectively. Life cycle assessment showed that LN strategy can reduce the environmental impacts of climate change and terrestrial ecotoxicity by about 4%, acidification and eutrophication by 8% and 10%, respectively, and land occupation by 9%. Data suggest that nutritional adjustment is a valuable alternative to standard formulations, without affecting performance, but lowering costs and reducing environmental burdens.

We examined the influence of land use change, tillage system and soil texture on organic carbon (C) stocks and on organic matter composition of tropical and subtropical soils from Brazil at four long-term experiments (11–25 years) based on fine- and coarse-textured soils. Soil samples were collected from the 0–5, 5–10 and 10–20 cm layers of conventional tillage (CT) and no-till (NT) plots, and of the adjoining soil under native vegetation (NV) of Cerrado (tropical) or grassland (subtropical). Conversion of NV to CT resulted in losses of 7–29% of the original C stock of 0–20 cm; conversion to NT increased this C stock by 0–12% compared with CT. Organic matter composition of the 0–5 cm layer, assessed by solid state CPMAS-13C-NMR, ESR and laser induced fluorescence spectroscopies, was affected by land use and tillage systems. Conversion of NV to CT decreased O-alkyl and increased aromatic, carbonyl, aromatic/O-alkyl ratio, free radicals concentration and fluorescence signal. The opposite trend was observed when NT replaced CT. The relative losses and gains of C and qualitative changes resulting from land use and tillage were less evident in fine- than in coarse-textured soils, suggesting a greater resistance and a smaller resilience of fine- compared with coarse-textured soils. The direct relation between increase in C stock and increase in potentially labile moieties (e.g. O-alkyl) and the decrease in more recalcitrant moieties (e.g. aromatics) in NT soils suggests that spatial inaccessibility by aggregates is playing a major role, compared with selective preservation, in promoting C accumulation in NT soils.
