“…As evidenced in the loading plot, the CP : NSP ratio in the diets and NH 3 concentration in the colon digesta were positively correlated, whereas NSP and NH 3 concentration in the colon digesta were negatively correlated. This is in line with the observations by Le et al (2008) that both the NSP content and the CP : NSP ratio in the diets affect the NH 3 concentration in the Fibre fermentation and nitrogen excretion in pigs pig intestine. The result of this study is also supported by the findings of O'Connell et al (2006) that the excretion of N and NH 3 from pigs is influenced by the dietary protein level, and the effect interacts with the fibre content in the diet.…”

To study the fermentation characteristics of different non-conventional dietary fibre (DF) sources with varying levels of indigestible CP content and their effects on the production of fermentation metabolites and on faecal nitrogen (N) excretion, an experiment was conducted with 40 growing pigs (initial BW 23 kg) using wheat bran (WB), pea hulls (PH), pea inner fibres (PIF), sugar beet pulp (SBP) or corn distillers dried grains with solubles (DDGS). The diets also contained soya protein isolate, pea starch and sucrose, and were supplemented with vitamin-mineral premix. Faecal samples were collected for 3 consecutive days from day 10, fed with added indigestible marker (chromic oxide) for 3 days from day 13 and pigs were slaughtered on day 16 from the beginning of the experiment. Digesta from the ileum and colon were collected and analysed for short-chain fatty acids (SCFA) and ammonia (NH 3 ) content. The apparent total tract N digestibility was the lowest (P , 0.001) in diets based on DDGS (74%), medium in diets with WB and SBP (76% each) and highest in those with PIF and PH (79% and 81%, respectively). Expressed per kg fermented non-starch polysaccharides (NSP), faecal N excretion was higher with DDGS and WB diets (130 and 113 g/kg NSP fermented, respectively) and lower with PIF, PH and SBP diets (42, 52 and 55 g/kg NSP fermented, respectively). The PH-based diets had the highest (P , 0.05) SCFA concentrations, both in the ileum and the colon (27 and 122 mMol/kg digesta, respectively). The highest NH 3 concentration was also found in the colon of pigs fed with PH (132 mMol/kg digesta). Loading plot of principle component analysis revealed that the CP : NSP ratio was positively related with faecal N excretion and NH 3 concentration in colon contents, whereas negatively related with SCFA concentration in colon contents. In conclusion, pea fibres and SBP increased SCFA and reduced NH 3 concentration in the pig's intestine and reduced faecal N excretion, which makes pea fibres and SBP an interesting ingredient to use in pig diet to improve the positive effect of DF fermentation on the gastrointestinal tract and reduce faecal N excretion.

“…Whereas Lynch et al (2008) obtained a 41% increase of odour emissions when sugar beet pulp was added to pig diets, a non-significant effect of FC was found by Clark et al (2005) and Le et al (2007). As acknowledged by Leek et al (2007) and Le et al (2008), the balance between dietary FC and CP plays an important role on odour production and emission. However, this relationship must be further explored.…”

Odours generated in livestock buildings constitute one of the most relevant air quality issues of intensive livestock production. Reducing nuisance episodes related to odour exposure is therefore essential for a sustainable livestock production. In this study, the state-of-the-art on odour mitigation techniques in livestock housing is critically reviewed. Scientific advances in the last decade are revised and research needs are also identified. The complex nature of livestock odours is firstly reviewed and examined. Then, the most relevant odour control strategies are analyzed in terms of present knowledge and future needs. The strategies considered are: nutritional strategies, manure additives, building design, air filtration, manure covers, manure treatment systems and windbreaks. Finally, future research needs and priorities when establishing mitigation techniques are identified. Despite important recent advances, there are still some challenges for scientists, producers and regulators, particularly related to field evaluation of odours. Therefore, to control livestock odours effectively, using standardized f ield assessment techniques will be required. Also, investigating measurement and model errors may be useful to better understand the limitations of the current methods, as well as to identify research priorities.

“…and growth performance in post-weaned piglets that lowering dietary protein levels has strong effect on NH 3 emission (Latimier & Dourmad, 1993;Canh et al, 1998a;Zervas & Zijlstra, 2002;Le et al, 2008). This is based on an average of 8% reduction in N excretion per unit of crude protein (CP) reduction (Kerr, 1995;Hobbs et al, 1996;Canh et al, 1998a), and would give similar piglet performance if diets are balanced in essentials amino acids (AA) (Hansen et al, 1993;Le Bellego & Noblet, 2002).…”

The objective of this study was to assess the effects of different dietary strategies in post-weaned piglets on gas emissions and animal performance. Eighty piglets were allotted in ten environmentally-controlled chambers. Piglets were fed with five different isoenergetic diets: control, low protein (LP), inclusion of sugar beet pulp (SBP), addition of benzoic acid (BA) and a combination of LP, SBP and BA (LP + SBP + BA). The gases analyzed were ammonia (NH 3 ), methane (CH 4 ), nitrous oxide (N 2 O) and carbon dioxide (CO 2 ). For NH 3 , the most effective treatment was LP, with a reduction of 61%. The LP + SBP + BA reduced NH 3 emission by 51%, the inclusion of SBP by 43% and the least effective technique was BA, which decreased by 9.5%, compared to control. The CH 4 emission was reduced by 30% for LP, but was increased by 23% for SBP and 24.6% for LP + SBP + BA. Benzoic acid did not differ from control group. The N 2 O emission did not show statistically differences, and CO 2 and carbon dioxide equivalent (CO 2eq ) emission increased with LP + SBP + BA (14 and 15% respectively), but were not affected by other diets. No effect of dietary treatment was observed on the growth performances compared with control group (p > 0.05). We can conclude that the best technique to reduce NH 3 emission was LP. Inclusion of SBP decreases NH 3 emission, but can increase greenhouse gas emissions. It would be interesting to evaluate the effect of higher percentages of BA because the promising results. Combining techniques is not a good strategy to obtain an additive effect in gas emissions reduction.
