“…Impacts were calculated at the farm gate and the functional unit considered was 1 kg of body weight gain (BWG) over the nursery stage. The starting pig production system considered was a conventional nursery farm with indoor rearing of castrated males on partially slated floor, where manure was kept in a pit under the slats during 24 h and scraped daily (during the morning) into open slurry tanks without a natural crust cover (Cherubini et al, 2015).…”

“…We assumed that soybean was produced in southern Brazil, the second largest soybean producer in the country (CONAB, 2016). However, to perform the calculations for global warming potential (GWP) and cumulative energy demand (CED), the most affected categories by soybean origin (Monteiro et al, 2016), we hypothesized that 98 % of soybean comes mainly from the central-western Brazil, as proposed by Cherubini et al (2015). Life cycle inventory for maize and soybean came from Alvarenga et al (2012) and Silva et al (2010), respectively.…”

“…This raises the question of whether this average data can be considered an adequate representation of the nutrient excretion by pigs, due to the dynamic phenomenon of dietary nutrient use, which changes over the fattening period (van Milgen et al, 2008). In addition, although several studies have been conducted on pig supply chains, to our knowledge, few studies have evaluated LCA in nutritional approaches in Brazil (Cherubini et al, 2015;Monteiro et al, 2016). Therefore, this study assessed the environmental impact of raising pigs fed with different levels of dietary CP, based on LCA methodology with observed individual data of performance and excretion.…”

The objective was to evaluate the impact of producing piglets fed diets with different crude protein (CP) levels through life cycle assessment and experimental data. In Trial I (performance), 28 crossbred barrow piglets, with an initial average weight of 15.3 ± 1.15 kg were divided into a randomized block design with four treatments, seven replications and one animal per experimental unit. In Trial II (nitrogen and phosphorus balance), 20 crossbred barrow piglets with an average weight of 21.4 ± 1.62 kg were divided in a randomized block design with four treatments, five replications and one animal per experimental unit. Four experimental feeds were evaluated: HighCP, CP18, CP17 and LowCP, with 19, 18, 17 and 16 % of CP, meeting the requirements of digestible amino acids through industrial amino acid (IAA) addition. From Trial I and II data, the environmental impact was calculated for global warming potential, acidification potential, eutrophication potential, cumulative energy demand, terrestrial ecotoxicity and land occupation (LO). Total nitrogen excretion decreased by 0.226 g d -1 for each 1 g of reduction on daily nitrogen intake. However, there was no statistical difference (p > 0.05) among experimental treatments for all impact categories. For LO, there was a reduction (p = 0.078) of impact with CP reduction, which was 8 % lower with the LowCP diet, in comparison with HighCP. Dietary CP reduction for piglets from 15 to 30 kg, through IAA supplementation, reduced the environmental impact under LO, considering soybean meal from southern Brazil and observed individual data of performance and excretion.

“…The GWP of the finishing stage in swine production under four scenarios of dietary CP (18, 16, 15 and 13%) was calculated by CHERUBINI et al (2015b). In the evaluation of feed composition, CP18 (no soybean hulls or maize starch) showed the best environmental performance for GWP.…”

Environmental impacts of livestock systems, especially pig production, have come under increasing debate in recent years. The challenge is in meeting the growing demand for food at an affordable cost, without compromising environmental integrity. Previous studies have shown that feed production is responsible for the majority of CO2-eq. emission resulting from pig farming systems. This seems to indicate that feed strategies could be an effective tool to achieve the sustainability of the pork chain. Therefore, dietary crude protein reduction, through the addition of industrial amino acids, lessens the nitrogen excretion by pigs and, consequently, could mitigate the effects on the environment of pig production. In this sense, to effectively evaluate the environmental impacts of pig production systems, life cycle assessment has been widely used in agriculture, but the effects of feed are still understudied in Brazilian conditions. Owing to the importance and the great concern in this research area, we presented in this paper an updated review focusing on the nutritional techniques and their potential to reduce the global warming potential of pig production, considering both the direct effects, related to the choice of feed ingredients and the indirect effects, related to changes in the efficiency of use of nutrient by the animals.
