“…The reduction of dietary CP content led to a slight increase in AP and EP impacts per kg of feed (Table 1). This result was also observed in previous studies (Mosnier et al, 2011;Garcia-Launay et al, 2014;Mackenzie et al, 2016;Monteiro et al, 2016Monteiro et al, , 2017b.…”

“…Nitrogen and phosphorus contribute to the eutrophication process and nitrogen contributes to the acidification process by ammonia emissions (Guinée et al, 2002). For this reason, most research evaluating the effect on dietary CP reduction for pigs reported a reduction on AP and EP with low CP diets (Ogino et al, 2013;Garcia-Launay et al, 2014;Mackenzie et al, 2016;Kebreab et al, 2016). In the above-mentioned researches, data were not evaluated statistically and the effect of between-animal variability was also not taken into account.…”

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.

“…Comparing diets based on meat meal, with dietary CP of 147g kg -1 , and diets based on bakery meal, with 132g CP kg -1 , AP and EP impacts were reduced by about 6 and 7%, respectively, for each percentage unit of dietary CP reduction (MACKENZIE et al, 2016). According to KEBREAB et al (2016), the addition of industrial AA and phytase to pig diets also reduced EP and AP in all the regions studied.…”

“…The study carried out by MACKENZIE et al (2016) showed that using meat meal in pig diets increased the dietary CP compared to a control feed based on maize and soybean meal (147 vs. 133g CP kg -1 , respectively). However, the GWP of one kg of pig carcass was 2% lower when pigs were fed diets based on meat meal, in a Canadian pig farming system.…”

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.

“…Incorporation of SBP (10%) into a poultry diet based on corn, sunflower meal, barley, and wheat increases its water-holding capacity (+30%) and its swelling capacity (+15%) . Its use in goose diets has no detrimental effects on geese reared for meat production (Arslan, 2003(Arslan, , 2005 and could help mitigate the environmental consequences of both the animal production system (Mackenzie et al, 2016) and the biofuel industry (Popp et al, 2016). Additionally, Arroyo et al (2015) showed that SBP incorporation (10%) in a complete pelleted diet for geese reared for foie gras production tended to increase the crop volume of the birds (+8%).…”

The aim of this work was to study the effects of incorporating sugar beet pulp (SBP) into the diet of geese in two feeding systems (complete pelleted feed or loose-mix feeding system) on crop development and performance. A total of 480 1-d-old male geese were divided into three groups whose diet differed from d 56 to 90: a complete pelleted diet containing 50% corn (control diet: AME n 11.5 MJ/kg; CP 161 g/kg), and no SBP; a complete pelleted diet containing 50% corn and 10% SBP (SBP cp diet: AME n : 11.5 MJ/kg; CP: 161 g/kg); and a mix in the same feeder (SBP lm diet) of 500 g/kg of protein-rich pellets containing 20% SBP (SBP prp : AME n : 9.0 MJ/kg; CP: 250 g/kg) and 500 g/kg of whole corn (WC: AME n : 14.0 MJ/kg; CP: 72 g/kg). Body traits, including crop volume, were measured at d 91. From d 91 to 106, 88 birds/group were overfed with a mixture containing mainly corn and water before slaughter to measure fatty liver performance. Feed intake from d 56 to 90 was higher (+10%; P = 0.004) in the SBP cp group than the other two, but at d 90, the body weight (BW) of the birds was higher (+7%; P = 0.002) in the SBP lm group than the other two. At d 91, the volume of the crop was greater in the SBP cp group (80.4 mL/kg of BW, P < 0.001) than in the control group (60.3 mL/kg of BW), the SBP lm group being intermediate (64.1 mL/kg of BW). Feed intake (13,321 g), weight gain (2,733 g), and feed-to-gain ratio (4.9) during the overfeeding period, as well as fatty liver weight (963 g) and commercial grading, were similar (P > 0.05) between the three groups. In conclusion, the use of sugar beet pulp in the diet of finishing geese helps the adaptation of the digestive tract to the overfeeding period, even in a loose-mix feeding system based on whole corn.
