“…Table 1 shows a mean recovery rate of 1.04 ± 0.05 with a recovery range from 0.99 to 1.12. The recovery rates were similar to those reported by [14][15][16], indicating that the operation of the head-box respirometry system is within acceptable international standards. The system was capable of detecting accurately small volumes of methane released, a feature not available in some chambers because methane tends to dilute with the air within the chamber [14].…”

“…This was conducted to determine the CH 4 recovery rate of the system in order to comply with adequate international standards of chamber operation as suggested by [13]. The gravimetrical method described by Arceo-Castillo et al [14] was used to conduct the recovery test. Pure CH 4 gas (calibration gas PRAXAIR, Mexico UN-1971, key ME2.0-D34), was released in different assays.…”

“…The recovery rates were calculated based on the gravimetric volume (L) of methane released into the respiration chamber, a precision balance was used to continuously weigh the CH 4 cylinder considering a methane density of 0.716 g L −1 and the methane volume recovered in the analyzer during the duration of each experimental run. For the calculations, the procedure described by Arceo-Castillo et al [14] was used as shown in Equations ( 1)-( 3):…”

This paper aims to describe the construction and operation of a respiration chamber of the head-box type for methane (CH4) measurements in bovines. The system consists of (1) a head box with a stainless steel frame and acrylic walls, floor, and ceiling; (2) a stainless steel feeder; (3) an automatic drinking water bowl; (4) a hood made from reinforced canvas; (5) an infrared (IR) CH4 gas analyzer, a mass flow generator, a data-acquisition system; and (6) a steel metabolic box. Six assays were conducted to determine the pure CH4 recovery rate of the whole system in order to validate it and comply with standards of chamber operation. The gravimetrical method was used for the recovery test and the recovery rate obtained was 1.04 ± 0.05. Once the system was calibrated, measurements of CH4 were conducted using eight animals consisting of four Holstein cows with a live weight of 593.8 ± 51 kg and an average milk yield of 23.3 ± 1.8 kg d−1 and four heifers with a live weight of 339 ± 28 kg. The CH4 production values were 687 ± 123 and 248 ± 40 L CH4 d−1 for cows and heifers, respectively. The CH4 yield was 19.7 ± 3.4 g and 17.1 ± 3.4 g CH4 kg−1 of dry matter consumed for cows and heifers, respectively. These results are consistent with those reported in the literature.

“…All the data from the 48 h measurement were used to calculate daily CH 4 emissions. Before the beginning of the experiment, a CH 4 recovery test was conducted as described by Arceo-Castillo et al [28] for the types of chambers used in the present experiment, and a 100 ± 2% recovery rate was found.…”

The objectives of the present work were to evaluate the in vivo antimethanogenic effects of Cymbopogon citratus (CC), Matricaria chamomilla (MC) and Cosmos bipinnatus (CB) on beef cattle fed a high in concentrate diet (forage-to-concentrate ratio [F:C] of 19.4:80.6), and the effects of increasing levels of CC (0%, 2%, 3%, and 4% of the daily DM intake (DMI)) on enteric CH4 emissions by beef cattle fed a ration low in concentrate (F:C ratio of 49.3:50.7). Two experiments were conducted to address the objectives. For the first experiment, eight Charolais × Brown Swiss steers distributed in a replicated 4 × 4 Latin square experimental design were used. Four treatments were evaluated: (1) control diet (CO), (2) CO + 365 g dry matter (DM)/d CB, (3) CO + 365 g DM/d MC, (4) CO + 100 g DM/d CC. For Experiment 2, four Charolais x Brown Swiss steers distributed in a single 4 × 4 Latin square design were used. It was concluded that 100 g DM per day CC and 365 g DM per day CB (Experiment 1) reduced CH4 yield of beef cattle. In Experiment 2, CC supplementation levels exceeding 2% of DMI reduced daily CH4 emissions but at the expense of decreasing digestibility of DM.

The aim of the present study was to assess enteric methane (CH<sub>4</sub>) emissions by crossbred heifers fed a basal ration of low-quality tropical grass supplemented with different nitrogen sources. Four crossbred heifers (Bos taurus × Bos indicus) with an average live weight (LW) of 355 ± 6.01 kg were used in a 4 × 4 crossover Latin square design with four periods of fifteen days each. Basal ration was chopped low-quality tropical grass Pennisetum purpureum fed to cover ~70% of metabolizable energy requirements for maintenance of heifers and it was supplemented with either poultry litter (control ration, T1), urea (T2), canola meal (T3) or soybean meal (T4). Enteric CH<sub>4</sub> emissions of heifers were measured in open-circuit respiration chambers for 23 hours. Dry matter (DM), neutral detergent fibre (NDF) and acid detergent fibre (ADF) intakes decreased when feeding urea (1.6% of ration) as a source of nitrogen (7.64, 3.78, and 1.83 kg/d, respectively). Rations including urea (T2) or canola meal (T3) given to heifers fed a basal ration of low-quality Pennisetum purpureum grass significantly reduced acetic acid concentration and increased propionic acid concentration in the rumen and decreased the loss of gross energy as methane (P = 0.004). Incorporation of urea or canola meal in the ration of cattle fed low-quality tropical grass can decrease methane emissions and improve rumen fermentation patterns.
