“…The easiest way to obtain direct information about N emissions is to measure losses through the mass balance method [Pollet et al (1998); first applied for N balance studies by Estermann et al (2002) for individual animal manure storage experiments]. The manure is filled into uncovered flasks, pots, or barrels, and is stored under controlled environmental conditions.…”

“…The latter is difficult to achieve in ruminants as forced exhaust air systems are not common. Some research institutes have built identical animal compartments where a comprehensive assessment of gaseous N emissions across the individual compartments is possible (Pollet et al, 1998;Mathot et al, 2012;Mohn et al, 2018). As the number of test compartments is limited to few, this type of equipment is more suitable to generate information about developments with time and to confirm whether effects from balance experiments can be recovered in entire herds.…”

“…At the start and the end of the storage experiment, manures were thoroughly homogenised and samples were drawn. Total passive storage N losses were measured by the N balance technique (Pollet et al, 1998). The ventilators enforced NH 3 emissions during the short periods of measurement leading to an average overestimation accounting for the 1.81 fold level of that of the unforced emission as determined by comparing NH 3 emission rates integrated over storage time and actual N losses according to N balances.…”

This study investigated the effects of supplementing 40 g lauric acid (C12) kg(-1) dry matter (DM) in feed on methane emissions from early-lactating dairy cows and the associated effects on methane, nitrous oxide and ammonia release from the manure during storage. Stearic acid (C18), a fatty acid without assumed methane-suppressing potential in the digestive tract of ruminants, was added at 40 g kg(-1) DM to a control diet. The complete feed consisted of forage and concentrate in a ratio of 1.5:1 (DM basis). The manure was stored for 14 weeks either as complete slurry or, separately, as urine-rich slurry and farmyard manure representing two common storage systems. Methane release of the cows, as measured in respiratory chambers, was lower with C12 by about 20%, but this was mostly resulting from a reduced feed intake and, partly, from a lower rate of fibre digestion. As milk yield declined less than feed intake, methane emission per kg of milk was significantly lower with C12 (11.4 g) than with C18 (14.0 g). Faeces of C12-fed cows had a higher proportion of undigested fibre and accordingly methane release from their manure was higher compared with the manure obtained from the C18-fed cows. Overall, manure-derived methane accounted for 8.2% and 15.4% of total methane after 7 and 14 weeks of storage, respectively. The evolution of methane widely differed between manure types and dietary treatments, with a retarded onset of release in complete slurry particularly in the C12 treatment. Emissions of nitrous oxide were lower in the manures from the C12 treatment. This partially compensated for the higher methane release from the C12 manure with respect to the greenhouse gas potential. The total greenhouse gas potential (cow and manure together) accounted for 8.7 and 10.5 kg equivalents of CO2 cow(-1) d(-1) with C12 and C18, respectively. At unaffected urine-N proportion ammonia and total nitrogen losses from stored manure were lower with C12 than with C18 corresponding to the differences in feed and nitrogen intake. The present results suggest that manure storage significantly contributes to total methane emission from dairy husbandry, and that the identification of effective dietary mitigation strategies has to consider both the digestive tract of the animals and the corresponding manure.

“…On the other hand, irreversible N losses coefficient (N losses/manure N produced), in both systems was 35% and was in the upper range (24 to 34% of N losses) of the results provided from Belgium barns [36] and lower than 39% of N volatilization [37] during storage.…”

The aim of this study was to determine N recovery and irreversible losses (i.e., through NH3-N volatilization) from manure in two different housing systems throughout a year using an N mass balance approach. Dietary, milk, and manure N were monitored together with outside temperatures in six dairy barns during six months, comprising two different seasons. Three barns were designed as conventional free stalls (cubicle, CUB) and the other three barns as compost-bedded packs (CB). All the barns were located in the Ebro’s valley, in the northeast of Spain. Mass N balance was performed simultaneously in the six barns, during two three-month periods (Season I and II) and sampling at a 15-day interval. Results of ANOVA analysis showed that annual N retained in manure (kg/head per year) from cows housed in CUB barns was significantly higher than in manure from cows housed in CB (133.5 vs. 70.9, p < 0.001), while the opposite was observed for N losses (26.9 vs. 84.8, for CUB and CB barn, respectively; p < 0.005). The annual mean proportion of irreversible N loss from manure in relation to N intake was much lower in barns using conventional free-stall cubicles than the mean ratio registered in bedded pack systems barns.
