Structural change in feedlot cattle death loss rates

Frontiers in Veterinary Science, 2023
IntroductionIndustry reports and anecdotal evidence indicate that the death loss rate in cattle feedlots has increased over time. Such increases in death loss rates impact feedlot cost and thus profitability.ObjectivesThe primary objective of this study ...

Emission Reporting for Agriculture: Frameworks and Metrics Matter

Australian Journal of Agricultural and Resource Economics, EarlyView.
ABSTRACT Frameworks and metrics that reliably describe agricultural emission sources and carbon sinks are critical to the formulation of cost‐effective mitigation investment. This study identifies and compares three distinct emission reporting frameworks across metrics of total emissions and emissions intensity.

‘Let's Turn the Grass Into Meat’: Animal Husbandry as Women's Work in Cold War North Korea

Gender &History, EarlyView.
ABSTRACT In postcolonial North Korea, the future of the nation was said to be a function of the feedlot. Unobtainable on the battlefields of the recently ended Korean War, liberation and unification of the peninsula became a question of competitive developmentalism.

Productive performance of Holstein calves finished in feedlot or pasture

Anais da Academia Brasileira de Ciências
The use of animals from dairy farms is an alternative to meat production since it provides an increment of total income for farmers. This study aims to evaluate the performance of Holstein calves finished in two feeding systems (feedlot or pasture ...

Effect of outdoor production, slurry management and buffer zones on phosphorus and nitrogen runoff losses from Finnish cattle farms [PDF]

, 2010
This thesis sums up studies on phosphorus (P) and nitrogen (N) losses to water from forested feedlots and slurry-amended grass fields. Moreover, different ways of mitigating the losses in a boreal climate are discussed.

Genetic Parameters of Methane Emission, Feed Efficiency, Feeding Behaviour, and Growth Traits in Beef Cattle

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT Climate change has intensified the need to reduce greenhouse gas emissions, particularly methane (CH4) from enteric fermentation. Genetic selection has emerged as a promising mitigation strategy; however, studies on Bos taurus indicus , especially Nellore cattle, remain limited.

Performance and carcass characteristics of lambs fed a solution of crude glycerin during feedlot and pre-slaughter lairage

Revista Brasileira de Zootecnia, 2018
The objective of this study was to evaluate performance and carcass and meat characteristics of lambs fed a solution of crude glycerin plus water (100 g kg−1 of dry matter) (GLY) during feedlot and pre-slaughter lairage.

A Contribution of Beef to Human Health: A Review of the Role of the Animal Production Systems [PDF]

, 2016
Meat and meat products constitute important source of protein, fat, and several functional compounds. Although beef consumption may implicate possible negative impacts on human health, its consumption can also contribute to human health.

Contribution of Fat Adjustment to Residual Feed Intake Estimation in Beef Cattle

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT Including fat thickness as a covariate in the regression model used to calculate residual feed intake (RFI) could help preserve carcass quality traits, such as marbling, flavour and juiciness, by accounting for variation in fat deposition.

Genetic Relationships Between Residual Gain and Economically Important Traits in Nellore Cattle

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT Sustainable beef production requires identifying animals with superior feed efficiency to reduce environmental impact and production costs. This study aimed to estimate heritability and genetic correlations between residual gain (RG) and growth, reproductive, carcass and feed efficiency traits in Nellore cattle.
