TL;DR: If the revised MP (g/day) approach is used to calculate Australia’s national inventory, it will reduce estimates of emissions of forage-fed cattle by 24%, which represents a 12.6 Mt CO2-e reduction in calculated annual emissions from Australian cattle.
Abstract: The methods for estimating methane emissions from cattle as used in the Australian national inventory are based on older data that have now been superseded by a large amount of more recent data. Recent data suggested that the current inventory emissions estimates can be improved. To address this issue, a total of 1034 individual animal records of daily methane production (MP) was used to reassess the relationship between MP and each of dry matter intake (DMI) and gross energy intake (GEI). Data were restricted to trials conducted in the past 10 years using open-circuit respiration chambers, with cattle fed forage-based diets (forage >70%). Results from diets considered to inhibit methanogenesis were omitted from the dataset. Records were obtained from dairy cattle fed temperate forages (220 records), beef cattle fed temperate forages (680 records) and beef cattle fed tropical forages (133 records). Relationships were very similar for all three production categories and single relationships for MP on a DMI or GEI basis were proposed for national inventory purposes. These relationships were MP (g/day) = 20.7 (±0.28) × DMI (kg/day) (R2 = 0.92, P < 0.001) and MP (MJ/day) = 0.063 (±0.008) × GEI (MJ/day) (R2 = 0.93, P < 0.001). If the revised MP (g/day) approach is used to calculate Australia’s national inventory, it will reduce estimates of emissions of forage-fed cattle by 24%. Assuming a global warming potential of 25 for methane, this represents a 12.6 Mt CO2-e reduction in calculated annual emissions from Australian cattle.

TL;DR: In the United States, about two-thirds of the beef cattle feeding in the USA occurs in Nebraska, Texas, Kansas, Iowa, and Colorado as mentioned in this paper, where over 80 percent of the fed cattle are produced in feedlots of over 1,000 head capacity.
Abstract: About two-thirds of the beef cattle feeding in the United States occurs in Nebraska, Texas, Kansas, Iowa, and Colorado. Over 80 percent of the fed cattle are produced in feedlots of over 1,000 head capacity. Manure produced by fed cattle, if all were conserved and utilized, would provide 100 kg nitrogen (N) ha−1 (89 lb N a−1) for 8.4 percent of the corn and wheat acreage in the nation. Nutrients excreted in beef feedlots would cost over $461 million if purchased as fertilizer. However, under present practices, about 50 percent of this N is lost (primarily by runoff, ammonia volatilization, and denitrification) before removal from the feedlot. In addition, 50 percent of the remaining N may be lost in hauling, spreading, and incorporating manure into the soil.
Phosphorus (P) losses are less, because P is lost primarily through runoff. Because beef feeding is concentrated where a high percentage of the land is cultivated, there is usually ample land area within economically acceptable distance on …

TL;DR: In this article, the authors examined the impacts of cattle packer forward contracting on cash cattle transaction prices in southwest Kansas from late May through November 1990, and estimated that average fed cattle cash transaction prices were estimated to be $ 0.15/cwt to $0.31/cw lower as a result of forward contract cattle shipments.
Abstract: Beef packers have vertically integrated into the cattle feeding sector. This study examines the impacts of beef packer forward contracting on cash cattle transaction prices in southwest Kansas. From late May through November 1990, average fed cattle cash transaction prices were estimated to be $0.15/cwt to $0.31/cwt lower as a result of forward contract cattle shipments. The impact of the level of forward contracting on cash prices was variable across time: cash prices were as much as $0.34/cwt lower at times when contract shipments were large, and prices were statistically unaffected at times when forward contract shipments were low.

TL;DR: In this article, a non-cooperative game theoretic model suggests that for tacitly collusive pricing behavior to persist in equilibrium, oligopsonists must follow a discontinuous pricing strategy.
Abstract: Market power in regional fed cattle markets is measured with an econometric model which links behavior of the margin between boxed beef and fed cattle prices to an economic model of conduct. A noncooperative game theoretic model suggests that for tacitly collusive pricing behavior to persist in equilibrium, oligopsonists must follow a discontinuous pricing strategy. Meatpackers pay low prices for cattle during cooperative phases and purchase cattle aggressively during noncooperative phases. Tests for cooperative/noncooperative conduct and measures of market power are presented. Fed cattle prices in four direct trade regions in the central United States are examined. Evidence of cooperative/noncooperative conduct is present in all markets but has declined over time. Varying conduct across markets and over time suggests it is important to continue monitoring fed cattle markets to assure a competitive environment.
