AbstractThe aim of the study was to present the scale of greenhouse gas emissions from animal production, and to provide test results from different housing systems. In three free stall buildings, two with slurry in deep channels and one with cattle in cubicles staying on shallow litter concentration of ammonia and carbon dioxide were measured in summer season by using dedicated equipment from Industrial Scientific Research. Air exchange was calculated on the base of balance carbon dioxide method. This method was used in order to estimate the air flow rate. Concentrations of ammonia and CO2 were measured as the base for air exchange and ammonia emission rates. Ammonia emissions were product of ammonia concentration and air exchange rate. Temperature and relative humidity were measured to establish microclimate conditions in buildings tested to show the overall microclimatic situation in buildings. Differences between ammonia emission rates were observed in both housing systems. The highest ammonia emission rate was equal to 2.75 g·h−1·LU−1 in well-ventilated cattle barn with the largest herd size.

Good Potential

This study aimed to make an analytical inventory of ammonia emission data of dairy housing systems and to assess possibilities for reduction, based upon the analysis of processes and factors involved in the production and volatilization of ammonia. Mass balance methods for the determination of air exchange rates for naturally ventilated dairy cow buildings that are based upon natural or introduced tracers may have good potential for application in emission studies. Differences occur in housing systems, floor types and manure collection and manure storage systems. Ammonia emission levels for cubicle (loose) houses are higher (20-45 g/day/cow) than for tie stalls (5-27 g/day/cow), and variation in emissions by housing type is large. Integration of knowledge of ammonia emission related processes and factors will support a more detailed analysis of differences and variation, and will allow optimization of possibilities for emission reduction. Substantial emission reductions of up to 50% for cubicle houses with slatted floors can be achieved through each of the following measures: flushing of floors with water or diluted formaldehyde, optimised feeding strategies, and slurry acidification. Highest reductions are possible through V-shaped, solid floors (52%) as a single measure, or in combination with flushing with water (65%) or diluted formaldehyde (80%). Providing that drawbacks are solved, nationwide introduction of one or more these measures will lead to a maximal reduction of the NH3 emission in the Netherlands to 18 kt per year.

Pair Wise Comparison

Odour nuisance from agricultural activities is increasing in densely populated countries like the Netherlands. To develop adequate regulations, a large-scale, government-financed monitoring programme was started in the mid-1990s to establish odour emission levels for both conventional and low ammonia emission housing systems for cattle, pigs and poultry. The results indicate that high- and low-odour emission housing are difficult to distinguish because of the large variation within housing systems. Measurements on different farm locations within the same housing system show both a large variation between locations and within one location (in time). The latter, however, is significantly smaller, which suggests that farm management is an important determinant in odour emission that interferes with the effects of housing systems. The current research was aimed at determining the effect of two common ammonia-reducing pig-housing systems on odour emissions compared to conventional housing systems under similar management conditions. The respective reduction principles of these systems are reducing the emitting surface of the manure pit and cooling of manure in the manure pit (both pits beneath slatted floor). Five farms that combined conventional housing with one low-ammonia system (three reduced emitting surface and two manure cooling) were selected for a direct, pair-wise comparison of (olfactometric) odour emission measurements. The results show a highly significant effect (p < 0.01) for two of the three reduced emitting surface systems and for one of the two manure cooling system. The average odour reduction percentages of these systems are 35% (from 24.9 to 16.0 OUE/s per animal) and 23% (from 30.1 to 24.0 OUE/s per animal) respectively. Although odour emission reduction through the type of housing system is possible, management factors interact with the system and thereby determine whether the system reduces odour emission or not.

AbstractIn order to reduce ammonia emissions from pig housing systems, the Council of Europe proposes the use of part slatted flooring in preference to fully slatted flooring, but the effects of such changes on the health and welfare of pigs in the UK has not been defined. The aim of this experiment was to investigate the effects of different floor types on the emission of ammonia, behaviour and welfare, physical performance and respiratory and enteric health of growing/finishing pigs. This involved three replications of five treatments: 1) UK fully-slatted, 2) UK fully–slatted with rubber matting over 50% of the slats, 3) UK fully–slatted with “structural” modifications which involved “paving” over 50% of the floor and partitioning off the slurry channel beneath the solid floor, 4) UK part–slatted, and 5) novel Dutch partslatted with UK pig stocking density. Groups of 10 pigs (balanced for gender) weighing approximately 40kg were on–test for 10 weeks.

Nuisance from livestock facilities is an increasing problem in densely populated areas like The Netherlands. It is in the interest of both farmers and society that housing systems and management methods are developed to minimise the emission of odour. An odour research programme has been completed in The Netherlands to investigate odour emission from both conventional housing systems and systems designed for low ammonia emission. The aim of this paper is to compare within each animal category the odour emission of a number of swine housing systems and poultry housing systems. Emission measurements including 17 housing systems were carried out at 24 livestock facilities. Results showed that investigated systems with low ammonia emission for fattening pigs and sows were significantly (p<0.025) lower than conventional systems, being 50%, or more, lower. For laying hens and broilers, housing systems with low ammonia emission showed odour emissions that in most cases only differed slightly from conventional systems. Correlations between ammonia and odour concentration (within facilities) did not show a consistent pattern. It is concluded that methods for restriction of emitting (slurry) surface in pig husbandry may reduce both ammonia and odour emission. In poultry housings the effects of methods for ammonia reduction that involve drying of fresh manure or litter cannot be directly extrapolated to odour emision.
