“…There was good agreement between the CH 4 production values of individual finishing beef cattle measured by a hood system and their subsequent daily CH 4 outputs by RC [ 74 ]. The mean CH 4 yield in dairy cows obtained in a head box type system was also in line with those reported in RC but with a 70% lower cost in construction [ 20 ].…”

“…A ventilated hood or respiration head box is designed as a simplified RC using similar principles in gas measurement which covers only the animal’s head instead of its whole body [ 20 , 21 ]. The ventilated hood provides enough space for the movement of the animal’s head and free access to feed and water.…”

“…Traditional techniques in quantifying enteric CH 4 emissions include open-circuit respiration chamber (RC) for individual indoor animals [ 10 , 11 , 12 ] and sulfur hexafluoride (SF 6 ) tracer technique for individual and herd animals, both indoor and outdoor [ 13 , 14 , 15 ]. Other measurement techniques such as GreenFeed (GF) [ 16 , 17 ], sniffer method [ 18 , 19 ], ventilated hood [ 20 , 21 ], facemask [ 22 , 23 ], laser CH 4 detector (LMD) [ 24 , 25 ] and portable accumulation chamber (PAC) [ 26 , 27 ] are also reported.…”

To identify relationships between animal, dietary and management factors and the resulting methane (CH4) emissions, and to identify potential mitigation strategies for CH4 production, it is vital to develop reliable and accurate CH4 measurement techniques. This review outlines various methods for measuring enteric CH4 emissions from ruminants such as respiration chambers (RC), sulphur hexafluoride (SF6) tracer, GreenFeed, sniffer method, ventilated hood, facemask, laser CH4 detector and portable accumulation chamber. The advantages and disadvantages of these techniques are discussed. In general, RC, SF6 and ventilated hood are capable of 24 h continuous measurements for each individual animal, providing accurate reference methods used for research and inventory purposes. However, they require high labor input, animal training and are time consuming. In contrast, short-term measurement techniques (i.e., GreenFeed, sniffer method, facemask, laser CH4 detector and portable accumulation chamber) contain additional variations in timing and frequency of measurements obtained relative to the 24 h feeding cycle. However, they are suitable for large-scale measurements under commercial conditions due to their simplicity and high throughput. Successful use of these techniques relies on optimal matching between the objectives of the studies and the mechanism of each method with consideration of animal behavior and welfare. This review can provide useful information in selecting suitable techniques for CH4 emission measurement in ruminants.

“…Despite the numerous studies related to CH 4 emissions, the methodology of determining CH 4 emissions from individual animals is very diverse. Methods could be classifi ed into long-term, intended for measuring CH 4 emissions during a 24-hours period, and short-term methods, based on measurements of enteric CH 4 emissions in exhaled or eructated gas in short (minute) intervals over a few consecutive days [3,[11][12][13][14][15]. The respiration chamber as a long-term method of measuring CH 4 emissions is used as the "gold standard".…”

Methane Emission and Metabolic Status in Peak Lactating Dairy Cows and Their Assessment Via Methane Concentration Profile

et al. 2023

Ruminant husbandry contributes to global methane (CH4) emissions and beside its negative impact on the environment, enteric CH4 emissions cause a loss of gross energy intake in cows. The study is aimed to estimate CH4 emission and metabolic status in dairy cows via the methane concentration profile as a tool for analyzing the CH4 production pattern. The study included eighteen cows whose enteric CH4 emission was measured during three consecutive days in three periods: 2 hours before (P1), 2–4 hours (P2) and 6–8 hours (P3) after the morning feeding. Based on CH4 enteric emissions, cows were divided into two groups (n=6, respectively): HM (average CH4 concentration: 5430.08 ± 365.92 ppm) and LM (average CH4 concentration: 1351.85 ± 205.20 ppm). Following CH4 measurement, on day 3, venous blood was sampled to determine the indicators of the metabolic status. HM cows had significantly higher average CH4 concentrations, maximum and average CH4 peak amplitude than LM cows in all measuring periods (P1-P3), while the number of CH4 peaks tended to be higher in HM than in LM cows in P2. There were no differences in the maximum and average CH4 peak width and average distance among two CH4 peaks between examined groups of cows. HM cows had significantly higher total protein concentrations and significantly lower total bilirubin and NEFA concentrations than LM cows. In conclusion, HM cows have a greater number of eructations and release more CH4 per eructation than LM cows, hence the differences in metabolic status are most likely related to the differences in their liver function.

“…Respiration chambers are the most known and well-established proposed gas emission measurement methods (Place et al 2011, Castelán Ortega et al 2020. A respiration chamber encloses an animal's pen for multiple days such that the animal's emitted gasses are measured by highly sensitive gas sensors that are able detect a number of gases within a controlled ventilated airstream.…”
