Selecting For Less: How Much Methane Can We Truly Breed Away?, Sean B. Crowley

ORBioM (Open Research BioSciences Meeting)

Background

Genetic selection has potential to reduce enteric methane emissions from cattle, but a key challenge is determining how much of the genetic variation in methane traits is independent of traits already targeted in breeding programs, such as feed intake and growth.

Methods

Methane and carbon dioxide emissions were recorded in 1,700 crossbred, indoor-fed beef cattle using Greenfeed systems. Performance data included feed intake, metabolic liveweight, average daily gain, carcass weight, and ultrasound and skeletal traits. Genetic parameters and correlations among traits were estimated using animal linear mixed models to quantify the independence of methane-related genetic variation.

Results

Daily methane …

One Health Interventions And Challenges Under Rural African Smallholder Farmer Settings: A Scoping Review, Evanson R. Omuse, Honest Machekano, Bonoukpoè M. Sokame, Daniel M. Mutyambai, Thomas Dubois, Sevgan Subramanian, Frank Chidawanyika

All Peer-Reviewed Publications

The global human population is rapidly increasing, escalating interactions of people, animals and the environment. This has led to more convoluted health challenges, for which African smallholder farmers bear the brunt. The One Health (OH) approach recognises the interconnectedness of these health challenges and thus follows a transdisciplinary approach involving diverse stakeholders to address them. Although there have recently been global concerted efforts and studies on OH, an information gap exists in Africa, particularly regarding smallholder farmers and their needs. Additionally, evaluation frameworks and outcome metrics for OH initiatives are still unclear. Thus, this study was conducted to critically map …

Tube-Feeding A Calf, Cheyenne Reid, Reganne K. Briggs, Melanie Heaton, Rebekah Esplin, David Secrist

Do Behavioral Attitudes Of Livestock Farmers In Cameroon Influence The Adoption Of Insect-Based Feed? An Application Of The Theory Of Planned Behavior, Ruth T. Nembu, Boris D. Soh Wenda, Hervé K. Mube, Hervé W. Napi, Shaphan Y. Chia, Sali A. Ndindeng, Rodrigue B. Kamga, Dorothy E. Fon

All Peer-Reviewed Publications

This study investigates the effects of behavioral factors on the adoption of insect-based feed technology among livestock farmers in Cameroon. We use partial least squares structural equation modeling (PLS-SEM) to analyze primary data collected from 131 poultry and fish farmers in the Centre region of Cameroon. Our findings reveal that 18.32 % of the surveyed farmers are users of insect-based feed, whereas 81.68 % are non-users. We also show that livestock farmers’ attitudes directly influence the decision to use insect-based feed. Our findings suggest that perceived behavior control and subjective norms indirectly reinforce the decision to use insect-based feed-through attitudes. …

Stomoxys Flies (Diptera, Muscidae) Are Competent Vectors Of Trypanosoma Evansi, Trypanosoma Vivax, And Other Livestock Hemopathogens, Julia W. Muita, Joel L. Bargul, John Mark O. Makwatta, Ernest M. Ngatia, Simon K. Tawich, Daniel K. Masiga, Merid N. Getahun

All Peer-Reviewed Publications

Stomoxys flies are widely distributed and economically significant vectors of various livestock pathogens of veterinary importance. However, the role of Stomoxys spp. in pathogen transmission is poorly understood. Therefore, we studied the feeding patterns of these blood feeders collected from specific locations in Kenya to identify various vertebrate hosts they fed on, the livestock hemopathogens they carried, and to elucidate their role in pathogens transmission. Our findings show that field-collected Stomoxys flies carried several pathogens, including Trypanosoma spp., Anaplasma spp., and Theileria spp., which were also detected in the blood of sampled livestock, namely camels and cattle. The findings on …

The Thai Journal of Veterinary Medicine

Reproductive performance is an economically important trait in beef cattle breeding and improvement programs, as it directly influences overall productivity. Key performance indicators, such as age at puberty (AP), age at first mating (AFM), age at first calving (AFC), calving intervals (CI), days open (DO), number of services per conception (NSC), conception rate (CR), and gestation length (GL), can be used to assess reproductive performance. This review summarized findings from previous studies on the reproductive performance of Bali cattle under various management conditions in Indonesia. The literature indicated a range of reproductive performances in Bali cattle, with AP varying from …

Summer Air Temperature Comparisons Between The Field And Woods In An Angus Beef Cattle Silvopasture In The Virginia Coastal Plain, Amy E. Edwards

Virginia Journal of Science

The objective of this study was to compare corresponding temperature readings from loggers in the field and woods in a silvopasture for Angus beef cattle. Results show that temperatures during the hottest part of the day are greater in the field than in the woods. Summary statistics show higher maximum, upper quartile, and median temperatures at the field logger with all data analyzed, indicating the temperatures in the field are overall higher than the woods, except during temperature inversions at nighttime. This highlights the importance of providing cattle with shade to prevent heat exhaustion and thermal stress, especially when the …

Defatted Black Soldier Fly Larvae Meal As A Substitute Of Soybean Meal In Dairy Cow Diets, D. J.M. Braamhaar, W. F. Pellikaan, D. List, D. Korir, C. M. Tanga, S. J. Oosting

All Peer-Reviewed Publications

The replacement of soybean meal (SBM) with insect meal, e.g. black soldier fly larvae meal (BSFLM), as an alternative protein source in livestock feed is gaining traction globally. To date, no in vivo studies have been conducted to test the impact of BSFLM on the milk production of dairy cows. This study quantified the effects of replacing SBM with defatted black soldier fly larvae meal (DBSFLM) in diets of lactating dairy cows on feed intake, milk production and composition, apparent total-tract digestibility, feed- and nitrogen use efficiency. Twelve lactating Holstein-Friesian cows were used in a replicated 3 × 3 Latin …

Two Unique Cases Of Ponderosa Pine Needle-Induced Abortions, Kevin D. Welch, Megan A. Dietz, Steven E. Edmonds, Dale R. Gardener, Daniel Cook

Poisonous Plant Research (PPR)

Ponderosa pine (Pinus ponderosa) needles can induce abortions in cows when consumed during the last trimester of pregnancy. Traditionally pine needle-induced abortions occur in areas where cattle are forced into a stand of ponderosa pine trees to seek shelter and feed during a winter storm that is either very cold, has heavy snow or high winds. However, here we report two incidences of pine needle-induced abortions in cattle that were unique. In one case, there was no weather-related event that forced the cattle into the stand of pine trees, rather the cattle went into the pine trees seeking …

Nebraska Beef Cow Breeding Herd As Capital Stock, Richard Perrin, Margarida Noelia De Aguiar Cunha Souza, Lilyan E. Fulginiti

Cornhusker Economics

Throughout her lifetime, the capital stock value of a cow first rises as the size/quality of calves increase, then declines because there are fewer calves expected over her remaining lifetime. The value later in life begins to rise in anticipation of culling value.

We estimate the age distribution of the Nebraska cow herd every year, then we estimate the capital value of each cohort. Adding these values across ages and adjusting to 2015 prices, we obtain the series of capital values, measured in terms of 2015 dollars.

In addition, we calculate the value of the annual flow of services provided …

Using Thermal Camera Drones In Beef Cattle Roundup, Justin Wyatt Clawson, Eric Galloway, Shalyn Drake, Shawn Barstow, Ross Israelsen, Michael Pate

All Current Publications

Using drones with thermal sensors can be an effective tool in finding and collecting livestock from summer mountain ranges in the West. Drones can complete searches in much less time than required on horseback in demonstrated areas. Using drones reduces the workload of the rider and horse, saving time and energy and reducing the risk of injury. With proper training and certification, livestock producers can use drones to locate cattle and perform many other cost-cutting operations.

Be Aware Of Basis Volatility When Using Price Risk Management For Calves And Feeder Cattle, Jay Parsons, Aaron Berger

Cornhusker Economics

Understanding basis volatility and the impact it has on the actual price received for calves or feeder cattle in relation to the CME Feeder Cattle Futures is important when considering price risk management opportunities. Currently, cattle markets are in a time frame where volatility appears to be like market conditions experienced in 2014 and 2015. These conditions should prompt producers to think through how basis volatility could impact the expected price they will receive for their calves or feeder cattle.

The Economics And Productivity Of Us Cow-Calf Production, Richard Nehring, Hannah Shear, Kelvin L. Leibold, Andrew Swanson

Journal of Applied Farm Economics

We explore US beef cow-calf production in 2018 and estimate net returns, returns to scale, and technical efficiency associated with backgrounding versus nonbackgrounding by size and production system. We determine the relative profitability of cow-calf operations by type, region, and size. Results, using both stochastic production frontier analysis and data envelopment analysis, indicate that larger operations tend to be more scale and technically efficient than smaller operations. While larger operations may be more scale and technically efficient and have lower variable costs per cow, off-farm income helps smaller operations become competitive. The availability of detailed cost of production information in …
