“…Our dataset covered a wide range beef cattle fed low‐quality crop residues and by‐products production systems in tropical regions (from growing to finishing). Zebu beef cattle in Thailand such as native Thai cattle have a low mature body weight of ~450 kg for females and ~550 kg for males, while Brahman cattle and Zebu beef cattle crossed with B. taurus can show a higher mature body weight (Marcondes, Tedeschi, Valadares Filho, & Gionbelli, ; Ogino et al., ). Nellore beef cattle, wide spread in Brazil and India, are also a small breed size, with a mature body weight of ~530 kg according to Marcondes et al.…”

“…Because of the importance of Y m in determining the accuracy of enteric methane emissions for national and global inventories (IPCC, 2006), we analyzed a range of Y m models of the associated beef cattle production system. The present dataset ( (Marcondes, Tedeschi, Valadares Filho, & Gionbelli, 2013;Ogino et al, 2016).

“…Predicting the Y m values at the farm level is a different task compared with tier 2. Indeed, describing the Y m trends from the direct measurements in cattle is challenging for a variety of reasons such as the importance of data on methane mitigation throughout the assessment of the carbon footprint values (Ogino et al, 2016). According to Kebreab et al (2008), predicted values equal observed values in a perfect model.…”

The enteric methane conversion factor (Y m) is an important country‐specific value for the provision of precise enteric methane emissions inventory reports. The objectives of this meta‐analysis were to develop and evaluate the empirical Y m models for the national level and the farm level for tropical developing countries according to the IPCC's categorization. We used datasets derived from 18 in vivo feeding experiments from 1999 to 2015 of Zebu beef cattle breeds fed low‐quality crop residues and by‐products. We found that the observed Y m value was 8.2% gross energy (GE) intake (~120 g methane emission head−1 day−1) and ranged from 4.8% to 13.7% GE intake. The IPCC default model (tier 2, Y m = 6.5% ± 1.0% GE intake) underestimated the Y m values by up to 26.1% compared with its refinement of 8.4% ± 0.4% GE intake for the national‐level estimate. Both the IPCC default model and the refined model performed worse in predicting Y m trends at the farm level (root mean square prediction error [MSPE] = 15.1%–23.1%, concordance correlation coefficient [CCC] = 0.16–0.18, R 2 = .32). Seven of the extant Y m models based on a linear regression approach also showed inaccurately estimated Y m values (root MSPE = 16.2%–36.0%, CCC = 0.02–0.27, R 2 < .37). However, one of the developed models, which related to the complexity of the energy use efficiencies of the diet consumed to Y m, showed adequate accuracy at the farm level (root MSPE = 9.1%, CCC = 0.75, R 2 = .67). Our results thus suggest a new Y m model and future challenges for estimating Zebu beef cattle production in tropical developing countries.

“…In the life cycle impact assessment phase, the impact category is selected and the potential environmental impacts are calculated for each category. In the livestock sector, the most recurrent categories of impacts are global warming, acidification, eutrophication and energy consumption [24,29,30]. In LCA, all relevant emissions and resources used throughout the life cycle of a product are aggregated and expressed per functional unit [31].…”

Environmental Impacts of the Beef Production Chain in the Northeast of Portugal Using Life Cycle Assessment

et al. 2018

The beef supply chain has multiple negative impacts on the environment. A method widely used to measure impacts from both the use of resources and the emissions generated by this sector is the life cycle assessment (LCA) (ISO 14040). This study aimed to evaluate a semi-intensive system (SIS) and an extensive organic system (EOS), combined with two different slaughterhouses located in the northeast of Portugal. The studied slaughterhouses are similar in size but differ in number of slaughters and in sources of thermal energy: natural gas (Mng) vs. biomass pellets (Mp). Four categories of environmental impact were evaluated: global warming potential (GWP), acidification potential (AP), eutrophication potential (EP), and photochemical ozone creation potential (POCP). As expected, higher impacts were found for SIS for all studied impact categories. Slaughterhouse activities, fertilizer production, and solid waste treatment stages showed little contribution when compared to animal production. Concerning the slaughterhouses activities, the main sources of environmental impact were the use of energy (electric and thermal) and by-products transportation.
