“…In our study, the NH 3 emissions were 92% of N emissions (NH 3 +N 2 O) of which were contributed 35, 25 and 40%, respectively, from housing, storage and soil application (Table 2). So, these values observed in each stage of manure management are comparable to values obtained in other studies, with higher NH 3 emissions in soil application followed by housing (Sommer et al, 2006). In addition, our estimates of emissions of NH 3 (expressed per litre of milk produced) are comparable with average values observed in dairy cattle farms located at Germany, Portugal and UK, with emissions that ranged between 7.5 and 7.7 g N/L milk (Fangueiro et al, 2008).…”

“…Then, the cattle slurry stored is applied to land as organic fertiliser. Gaseous emissions are related with animal health (e.g., mucous membrane irritation and pulmonary diseases related with NH 3 exposure), nutrition (e.g., methane (CH 4 ) losses from rumen and N excretion) and environmental (e.g., air quality, atmospheric deposition, global climate change) issues and occur at all stages of animal manure management, namely housing, storage and soil application (Sommer et al, 2006;Hristov et al, 2011Montes et al, 2013;Beccaccia et al, 2015;Hou et al, 2015). Consequently, mitigation measures have been proposed in Northern Europe countries, but few data are available for Southern Europe countries.…”

The aim of this study was evaluate the relationship between the intensity of milk production for a wide range of Portuguese commercial cattle farms and NH 3 and greenhouse gas (GHG) emissions from manure management and enteric fermentation. A survey was carried out at 1471 commercial dairy cattle farms (Holstein-Friesian) and the NH 3 , N 2 O and CH 4 emissions at each stage of manure management were estimated as well as CH 4 losses from enteric fermentation. Gaseous emissions were estimated by a mass flow approach and following the recommendations of IPCC guidelines. The manure management and enteric fermentation in a typical Portuguese cattle farm contributes with 7.5±0.15 g N/L milk produced as NH 3 and 1.2±0.22 kg CO 2 equivalent per litre of milk as GHG. Increasing milk production will significantly reduce NH 3 and GHG emissions per litre of milk produced. It can be concluded that a win-win strategy for reducing NH 3 and GHG emissions from dairy cattle farms will be the increase of milk production on these farms. This goal can be achieved by implementing animal breeding programs and improving feed efficiency in order to increase productivity.Additional key words: dairy cattle; enteric fermentation; gaseous emissions; manure management.

“…Amon et al (2001) evaluated slurry-and straw-bedded pen manure management systems for a tie stall dairy. When identical diets were fed to the cows, no significant differences were observed in average EFs for CH 4 (194.4 and 194.4 g LU À1 d À1 for slurry and straw systems, respectively) and N 2 O (610 to 619 mg LU À1 d À1 for slurry and straw systems, respectively).…”

“…Though winter in the Northern Great Plain can be severe, wind protection and bedding can make significant differences in cattle performance and profit, in addition to sequestering more nutrients in the manure that will increase fertilizer value. Amon et al (2001) used an environmental dynamic chamber that covered 27 m 2 of emitting surface, in a tie stall dairy, to measure and compare the effect of a slurryand straw-bedded pen to a slurry-based manure management system with regard to CH 4 , N 2 O, and NH 3 emissions. They observed no significant differences in average CH 4 (194.4 and 194.4 (Amon et al 2001).…”

Similarly, under northern climatic conditions, bedding is used on the feedlot pen surface for animal comfort, to absorb and hold water (Spiehs et al, 2012).…”

Greenhouse gas (GHG) emissions from concentrated animal feeding operations vary by stage of production and management practices. The objective of this research was to study the effect of two dietary crude protein levels (12 and 16%) fed to beef steers in pens with or without corn stover bedding. Manure characteristics and GHG emissions were measured from feedlot pen surfaces. Sixteen equal-sized feedlot pens (19 Â 23 m) were used. Eight were bedded approximately twice a week with corn stover and the remaining eight feedlot pens were not bedded. Angus steers (n ¼ 138) were blocked by live weights (lighter and heavier) with 7 to 10 animals per pen. The trial was a 2 Â 2 factorial design with factors of two protein levels and two bedding types (bedding vs. non bedding), with four replicates. The study was conducted from June through September and consisted of four~28-day periods. Manure from each pen was scrapped once every 28 days and composite manure samples from each pen were collected. Air samples from pen surfaces were sampled in Tedlar bags using a Vac-U-Chamber coupled with a portable wind tunnel and analyzed with a greenhouse gas gas chromatograph within 24 hr of sampling. The manure samples were analyzed for crude protein (CP), total nitrogen (TN), ammonia (NH 3 ), total volatile fatty acid (TVFA), total carbon (TC), total phosphorus (TP), and potassium (K). The air samples were analyzed for methane (CH 4 ), carbon dioxide (CO 2 ), and nitrous oxide (N 2 O) concentrations. The concentration of TN was significantly higher (p < 0.05) in manure from pens with cattle fed the high protein diets. The volatile fatty acids (VFAs) such as acetic, propionic, isobutyric, butyric, isovaleric, and valeric acids concentrations were similar across both treatments. There were no significant differences in pen surface GHG emissions across manure management and dietary crude protein levels.Implications: Livestock manure produces odor and emits GHGs (CO 2 , CH 4 , and N 2 O) at different stages of production and management practices that have significant environmental concerns. Thus, it is important to measure GHG contributions from different sources and develop appropriate mitigation strategies for minimizing GHG contribution from livestock production facilities. Two dietary protein levels (12 and 16%) fed to beef steers in pens with or without corn stover bedding were studied. The results indicated that dietary protein levels and bedding vs. no bedding had very little effect on GHG emissions and manure composition under open feedlot conditions in North Dakota climatic conditions and management practices. IntroductionThe overall gaseous emissions from concentrated livestock operations vary by animal type and growth stage due to different diets, daily feed intake, quality of diet, and feed conversion mechanism. In the U.S., total greenhouse gases (GHG) including methane emissions from agricultural sources (livestock production, agricultural soils, and rice production) were estimated to be approximately 500 metric tons CO 2 e...

The technique of multimode absorption spectroscopy (MUMAS) is reviewed in the context of laser‐based methods for gas sensing of multiple species. The principles and practical implementation of the method are outlined with examples of applications using lasers with outputs in spectral ranges from the visible to the mid‐infrared, including interband cascade lasers (ICLs) and quantum cascade lasers (QCLs). The advantages and limitations of MUMAS are considered relative to other laser‐based methods, and potential future developments and applications are suggested.
