“…These results obtained under barn conditions confirm previous studies performed under laboratory conditions (slurry samples) in which reduction by 30e40% were reported (O'Shea et al, 2009;Jarret et al, 2012).…”

“…The slurry moisture content can be partly influenced by the water consumption that was higher with CTD for gestating sows (þ1.0 L day À1 sow À1 , P > 0.05) and with HFD for fattening pigs (þ0.7 L day À1 pig À1 , P < 0.05). In the literature, the impact of fibrous diet on water intakes shows contradictory results as well for gestating sows (Philippe et al, 2008) as for growing pigs (O'Shea et al, 2009;Montalvo et al, 2013). In any case, the results about water consumption should be interpreted cautiously given the potential water spillage and the large individual variations (Philippe et al, 2008).…”

“…Consequently, the ratio of the excreted N is altered, resulting in reduced N excretion in urine as urea and shifted N excretion in faeces as bacterial proteins (O'Shea et al, 2009). The decrease in NH 3 emissions can be also explained by the reduction of the slurry pH due to volatile fatty acid (VFA) formation during fermentation in the large intestine and slurry (O'Shea et al, 2009). In the current experiment, most of the slurry characteristics were not statistically different regarding the diet.…”

“…Comparing a fibrous diet based on sugar beet pulp (SBP) with a control diet based on cereals, O'Shea et al (2009) observed a reduction of NH 3 emissions from slurry samples by 40%. Such a reduction is beneficial for pig health as ammonia is an irritant for the respiratory tract and also beneficial for the environment as ammonia contributes to fine particulates formation, eutrophication and acidification of ecosystems (Krupa, 2003).…”

“…Particularly, some studies propose different replacement frequencies for the first and second impingers (e.g. Canh et al 1998c;O'Shea et al, 2009; among others). However, the potential effects of different acid replacement frequencies were not reported in these studies.…”

PhD ThesisAnálisis de los factores que influyen en las emisiones de amoniaco y metano de purines porcinos: composición del purín y factores nutricionales El aumento del conocimiento depende por completo de la existencia del desacuerdo. Karl PopperEl planeta puede vivir sin nosotros. Pero nosotros no podemos vivir sin planeta. Anónimo ResumenLa presente Tesis Doctoral está enfocada a la caracterización de las emisiones potenciales de amoniaco (NH 3 ) y metano (CH 4 ) a partir de purines porcinos. En concreto, estudia la relación entre el consumo y la excreción de nutrientes, la composición de los purines y las emisiones potenciales de NH 3 y CH 4 y el valor agrícola potencial de los purines. Además, evalúa las metodologías de medición de las emisiones potenciales de NH 3 y CH 4 in vitro y propone estrategias para su optimización.Los objetivos de la presente Tesis Doctoral son: i) Caracterizar la composición, el potencial de emisión de NH 3 y CH 4 y el valor agrícola potencial de purines de granjas comerciales de España, ii) Evaluar la influencia de la inclusión en el pienso de una fuente de grasa (jabón cálcico de palma) y una fuente de fibra (pulpa de naranja) sobre la composición del purín y emisiones potenciales de NH 3 y CH 4 en cerdos en crecimiento y iii) Optimizar las técnicas de medición de las emisiones potenciales de NH 3 y CH 4 in vitro de purines de cerdo.Los resultados de esta Tesis indican que las características fisicoquímicas de purines de granjas comerciales de España varían ampliamente y el tipo de animal (madres vs. animales en crecimiento) afecta de forma relevante a los contenidos de nitrógeno total, nitrógeno amoniacal, potasio, calcio, cobre, sodio, zinc, ácidos grasos volátiles y el pH de los purines, y en consecuencia afectan también sus emisiones potenciales de NH 3 y CH 4 . Por lo tanto, la utilización óptima de purines de granjas comerciales como fertilizante agrícola o como insumo para la producción de biogás requiere su previa caracterización. Por otra parte, es probable que factores de manejo y el desperdicio del pienso por los cerdos en granjas comerciales influyan de forma relevante sobre las características de los purines y como tal sobre sus emisiones de NH 3 y CH 4 .La inclusión de jabón cálcico de palma (como fuente de grasa) y pulpa de naranja (como fuente de fibra) en dietas de cerdo de engorde produjo cambios significativos en la composición de purín. La inclusión de jabón cálcico de palma provocó mayores excreciones de extracto etéreo y proteína bruta, así mismo causó mayores emisiones de CH 4 y menores emisiones de NH 3 . La inclusión de pulpa de naranja alteró la composición fecal, ii pero no afectó significativamente a las emisiones de NH 3 y CH 4 . Por otro lado, se encontró evidencias de que menores consumos de proteína bruta (PB) (-14% de PB) permitiría reducir proporcionalmente mayores cantidades de emisiones de NH 3 (-66%). Esta misma tendencia se encontró entre la ingesta de energía bruta y las emisiones de CH 4 , de forma que reducciones de -20% en la ingesta de ...

Dietary manipulation of animal diets by reducing crude protein (CP) intake is a strategic NH 3 abatement option as it reduces the overall nitrogen input at the very beginning of the manure management chain. This study presents a comprehensive metaanalysis of scientific literature on NH 3 reductions following a reduction of CP in cattle and pig diets. Results indicate higher mean NH 3 reductions of 17 ± 6% per %-point CP reduction for cattle as compared to 11 ± 6% for pigs. Variability in NH 3 emission reduction estimates reported for different manure management stages and pig categories did not indicate a significant influence. Statistically significant relationships exist between CP reduction, NH 3 emissions and total ammoniacal nitrogen content in manure for both pigs and cattle, with cattle revealing higher NH 3 reductions and a clearer trend in relationships. This is attributed to the greater attention given to feed optimization in pigs relative to cattle and also due to the specific physiology of ruminants to efficiently recycle nitrogen in situations of low protein intake. The higher NH 3 reductions in cattle highlights the opportunity to extend concepts of feed optimization from pigs and poultry to cattle production systems to further reduce NH 3 emissions from livestock manure. The results presented help to accurately quantify the effects of NH 3 abatement following reduced CP levels in animal diets distinguishing between animal types and other physiological factors. This is useful in the development of emission factors associated with reduced CP as an NH 3 abatement option.
