Land use change and collaborative manureshed management in New Mexico

Journal of Environmental Quality, Volume 51, Issue 4, Page 602-613, July/August 2022., 2022
Abstract Agricultural communities of New Mexico regularly redistribute manure nutrients from dairies to nearby croplands to fulfill agronomic nutrient needs and protect water quality. Yet competition for water resources can result in land use change that affects these cooperative manure transfers.

Supplementing pre- and probiotic ingredients to feedlot steers: effects on health, growth performance, and physiological responses

Animal, 2023
Feedlot diets are often enriched with additives to mitigate health disorders and promote cattle performance, including the feed-grade antimicrobials monensin and tylosin.

Nitrous Oxide from Beef Cattle Manure: Effects of Temperature, Water Addition and Manure Properties on Denitrification and Nitrification

Atmosphere, 2020
Beef feedyards produce nitrous oxide (N2O), a potent greenhouse gas. Limited research has evaluated the processes that produce feedyard N2O, and how rainfall and temperature impact N2O losses.

Identifying Safety Training Resource Needs in the Cattle Feeding Industry in the Midwestern United States

Safety, 2019
Cattle feedyards are a high-risk environment. They are characterized by high rates of occupational injuries and illnesses. As such, there is a clear need to address the health and safety of cattle feedyard workers.

Longitudinal Evaluation of Salmonella in Environmental Components and Peripheral Lymph Nodes of Fed Cattle From Weaning to Finish in Three Distinct Feeding Locations

Journal of Food Protection, 2023
Salmonella prevalence in bovine lymph nodes (LNs) varies due to seasonality, geographic location, and feedyard environment. The objectives of this study were to (1) establish prevalence rates of Salmonella in environmental components (trough water, pen ...

Antimicrobial use in 22 U.S. beef feedyards: 2016–2017 [PDF]

Zoonoses and Public Health, 2020
AbstractThis study describes antimicrobial use in 22 U.S. beef feedyards by use of two metrics: milligrams of antimicrobial per kilogram of liveweight sold (mg/kg‐LW) and antimicrobial regimens per animal year (Reg/AY). The primary objectives were to determine the feasibility of collecting antimicrobial use data at the level of the production system ...

Nasopharyngeal Bacterial Prevalence and Microbial Diversity at First Treatment for Bovine Respiratory Disease (BRD) and Its Associations with Health and Mortality Outcomes in Feedyard Cattle

Microorganisms, 2023
Bovine respiratory disease (BRD) is an economically important disease in feedyards influencing both animal welfare and antimicrobial utilization. Major pathogens associated with BRD have been identified in previous research, but little information is ...

Determination of Feedyard Evaporation Using Weighing Lysimeters [PDF]

2004, Ottawa, Canada August 1 - 4, 2004, 2004
Six shallow, weighing lysimeters were installed near Etter, TX, to measure quasi-instantaneous evaporation rates from simulated feedyard surfaces. The data revealed a pronounced and consistent hygroscopic period during which the manure appears to have absorbed water from the atmosphere.

Integrating Genomics with Nutrition Models to Improve the Prediction of Cattle Performance and Carcass Composition under Feedlot Conditions. [PDF]

PLoS ONE, 2015
Cattle body composition is difficult to model because several factors affect the composition of the average daily gain (ADG) of growing animals. The objective of this study was to identify commercial single nucleotide polymorphism (SNP) panels that could

Cardiopulmonary remodeling in fattened beef cattle: a naturally occurring large animal model of obesity‐associated pulmonary hypertension with left heart disease

Pulmonary Circulation, Volume 9, Issue 1, Page 1-13, January-March 2019., 2019
The obesity epidemic in developed societies has led to increased cardiovascular diseases including pulmonary hypertension associated with left heart disease (PH‐LHD), the largest and fastest‐growing class of PH. Similar to obese humans, PH and heart failure (HF) are increasingly recognized in North American fattened beef cattle. We hypothesized that PH
