“…In sample D2 (3 g), we observe higher temperature fluctuations caused by overheating of the sample due to the insufficient thickness of the material. Kapuinem [37] wrote that the moisture content of the litter is an important factor that affects the temperature of the bedding material. We agree with the given statement since we recorded a higher ignition temperature for samples that were sufficiently dried.…”

Digestate is the material remaining after the anaerobic digestion of a biodegradable feedstock. The use of digestate as a bedding material is analyzed marginally. The aim of the paper is to monitor the change of the solid phase of digestate due to the action of radiant heat and, based on the results, determine the options of using the solid phase of the digestate for bedding material. Experimental determination of the digestate ignition temperature was carried out according to EN 50281-2-1 (1998) by a hotplate device. Different amounts of samples (3, 5, and 10 g) on the course of thermal degradation were monitored. The results showed higher temperatures of thermal degradation in samples of additionally dried digestate, where these processes were observed earlier in terms of time. Samples of 3 and 10 g of digestate are not suitable as bedding material due to the fire safety of the material.

“…The resting place base can be concrete or compacted soil. It is considered appropriate to make the barn height between 2.8-3.6 m depending on the climate conditions in closed free barns applied in beef cattle breeding in Kapuinen (2001). The height of the beef cattle barns suggested in this study was 3.5 m.…”

Livestock operations generally deal with dairy or beef cattle. Although sufficient attention is paid in design and construction of dairy barns since modern technology, mechanization and labor are used intensively in dairy barns, beef cattle barns are still constructed in traditional styles. However, in cattle barns planned for meat production, which is one of the most important protein sources of human beings, desired conditions should be provided at optimum levels. Working conditions of the workers should be improved, physical, chemical and biological characteristics of animal rations should be improved and hygienic production environment should be provided. Therefore, beef cattle barns should be designed and constructed in accordance with modern technologies and technical standards and regional conditions should be taken into consideration. In this study, planning and design criteria of beef cattle barns for cold climate regions were determined and 100 and 200-head capacity beef cattle barns were developed and designed for Van Province conditions.

“…Generally, the CH 4 flux is influenced by temperature which affects microbial activity; i.e., higher CH 4 emission with high temperature [25,26]. Studies on litter reported that temperature ranges from of 35 to 50 • C was the best for microbial activity, which can be achieved with a litter height of 20 to 30 cm [27,28]. In this study, the shallow height of the litter (10 cm) and relatively low air temperature (below 35 • C) resulted in low CH 4 flux during the summer (Figure 4).…”

Estimation of Greenhouse Gas Emission from Hanwoo (Korean Native Cattle) Manure Management Systems

et al. 2020

The agricultural sector is considered one of the major sources of greenhouse gas (GHG) emissions globally. The livestock industry as a significant contributor, is accounting for about 18% of GHG emissions measured in carbon dioxide (CO2) equivalent from agricultural practices. Depending on farming practices and climatic conditions, GHGs such as methane (CH4) and nitrous oxide (N2O) emissions from livestock agriculture can vary significantly. Country-specific emission factors are, therefore, needed for a precise estimation of GHG emissions and to avoid uncertainties. This study was aimed at estimating the CH4 and N2O emission fluxes from Hanwoo (the most famous and popular Korean native cattle) manure management systems. CH4 and N2O emission fluxes from litter in the Hanwoo cattle barn and composting lot were monitored and calculated for 52 weeks using the dynamic chamber method. The calculated monthly average fluxes of CH4 and N2O from litter in the cattle barn ranged from 0.0 to 30.0 ± 13.7 and 0.896 ± 0.557 to 2.925 ± 2.853 μg/m2 s, respectively during the whole measurement period. While during the composting period, the monthly average of CH4 and N2O emission fluxes were varied from 1.449 ± 0.783 to 86.930 ± 19.092 and 0.511 ± 0.410 to 2.629 ± 1.105 μg/m2 s, respectively. The calculated emission fluxes of CH4 and N2O from manure management systems in this study were almost 5.4 and 2.1 times, respectively higher than the values reported for the Asian, South and North American countries in the 2006 Intergovernmental Panel on Climate Change (IPCC) Guidelines for National Greenhouse Gas Inventories. Overall, this study initiates the process along with signifies the importance of developing country-specific GHG inventories for the effective reduction of GHG emissions from the livestock sector in Korea.
