Any deviation from a bright-red color leads to discounted price or beef is discarded. Limited data are currently available on the economic losses due retail discoloration. Therefore, objective of study was estimate losses, amount discarded, natural resource wastage, and environmental impact One-year total sales, sale values were collected 2 national chains 1 regional chain located in Southern United States, representing 5,034 stores 44 states. The US system life cycle parameters published...
Abstract This study analyzes empirically and graphically the effects of relative market price level on premiums discounts received associated with alfalfa hay quality. Findings indicate that at times when prices are elevated to average, there is no significant impact average received. Conversely, depressed statistically variations in across quality grades compared a characterized by prices. Understanding these dynamics can aid producers optimizing production decisions assist consumers...
Abstract The growing population is driving demand for animal protein which increases pressure on the agricultural industry. Vertical farming could potentially help by reducing land and water requirements while operating independently of weather. However, it unknown how sprouted barley (SB), grown in a controlled environment system, impacts typical measures production (body weight (BW) gain, dry matter intake (DMI), feed efficiency (G:F), feeding behavior, carcass traits, economics etc.),...
Abstract Consumers prefer beef to be bright, cherry red in color. As becomes discolored, consumers may perceive it unwholesome, reducing their willingness‐to‐pay (WTP). This study uses a choice experiment an online survey measure how discoloration affects consumer WTP for steak and ground beef. A cheap talk script combined with trap question designed simultaneously reduce hypothetical bias as well measurement error caused by inattentive respondents is included the survey. Results indicate...
The Best-Worst Scaling (BWS) case III method, also called the BWS 'multi-profile case.' has been widely used to characterize survey respondent preferences for market goods. method is similar conjoint analysis methods in that respondents select from a set of hypothetical item profiles with different attribute levels. Unlike methods, which allow their best/most preferred profile, asks 'best' and 'worst' each choice set. This study compares consumer willingness pay (WTP) estimates formats. Data...
Introducing Bos indicus (BI) genetics into a beef herd has the potential to increase environmental sustainability. When introducing BI genetics, there are concerns regarding negative impacts on temperament, growth, and carcass characteristics. Implants routinely used in United States, with majority of cattle feed receiving an anabolic implant improve growth efficiency, however research interaction between breed type implants is limited. This compared use influenced animals versus taurus...
This study compares the marginal and rank methods for analysing best-worst scaling case 2 data using a simulated an empirical example dataset. Simulation results suggest method improves accuracy of estimates compared to as measured by bias mean square error. The reduced on average 48% across all coefficient marginal-CL method. Results from align with those simulation added robustness findings.
Abstract Alfalfa is a commonly grown forage in the Intermountain West region of United States and often included diet dairy cattle. provides variety different nutrients, but nutrient content alfalfa varies depending on factors such as soil, region, cutting, climate. However, leaves tend to have less variation their than stems. Fractionating may be one way improve control nutrients provided when developing ration for heifers. The purpose this study was determine whether including fractionated...
Abstract Consumers prefer bright, cherry-red retail beef. Retailers often mark down the price of discolored beef for quick sale. However, following this practice could result in a net loss revenue if consumer willingness to pay (WTP) nondiscolored is negatively affected by presence choice set. Through hypothetical online survey and controlled in-person experiment, we determine that marketing together with increases most consumers’ evaluation of, but not their WTP for,
Abstract Alfalfa is often included in the diets of beef animals; however, nutrient content alfalfa variable depending on region which it grown, climate, soil, and many other factors. The leaf portion has a less composition than stem plant. variability that present plant can make development total mixed rations consistent difficult. As such, purpose this study was to determine how inclusion fractionated leaves stems impacts performance carcass quality finishing steers. Twenty-four steers were...
Dairy heifers developed in certified organic programs, especially those utilizing pasture-based management schemes, have lower rates of gain than raised nonorganic confinement production systems temperate climates, such as the Intermountain West region United States. This study investigates effects that different forages a rotational grazing system on development organically Jersey heifers. Over 3 years, 210 yearling were randomly assigned to one 9 treatments, including conventional control...
This study compares the paired-multinomial logit (MNL) and rank ordered (ROL) models for best-worst scaling case 2 data using both simulated an empirical example dataset. Results suggest paired-MNL ROL with complete ranking provide accurate rankings of all attribute levels. However, when incomplete ranked data, accuracy levels other than best/worst is inconsistent.
Recent research has suggested that different cattle breed types may respond differently to anabolic implant protocols of varying intensity. Therefore, the purpose this was compare in feedlot steers 2 types. Sixty were stratified by weight and a × 3 factorial design examining breeds: Angus (AN; n=38) or Santa Gertrudis influenced (SG; n=22), strategies: no (CON; n=20), moderate intensity protocol (d0 implant: Revalor-G, d56 Revalor-IS, d112 Revalor-S; MI; high Revalor-S, Revalor-200; HI;...
Basis risk or residual arising from disparity between an index's estimate of losses and actual is inherent in index-based insurance products. We approximate basis as the false negative probability (FNP) within pasture, rangeland, forage (PRF) rainfall index for south-central coastal region California. FNP on average that at least one two selected coverage intervals will fail to provide indemnity when a loss realized 48%. The reduced only 11% considering whether both realized.
Abstract We conduct sensory analysis and assess consumer preferences willingness to pay (WTP) for beef steaks from cattle fed hydroponically produced barley fodder (B-F) relative those conventional mixed rations (CON). Results suggest consumers do not differentiate between B-F CON when evaluating attributes possess similar WTP both treatments. Preference toward the treatment is demonstrated sustainability-conscientious informed about potential sustainability benefits of treatment. Producers...
Abstract Safflower grown in the western U.S. is often produced for birdseed mixes. Increasing demand products, combined with regional drought, has shrunk safflower availability. To satisfy growing demand, processors may look to contracting strategies incentivize production. We compare expected risk and corresponding certainty equivalents both from processor producer viewpoints under various mechanisms aversion levels. Results suggest that contracts containing a combination of lump sum...
Although various studies have evaluated individual factors that influence meat discoloration, limited research has assessed the effects of multiple ground beef cold chain parameters on color. This study combined storage temperature, time, display and time color economic losses due to poor management. Fresh chubs (81% lean) were randomly assigned combinations 3 temperatures (0, 4.5, 8.9°C), 4 times 4, 8, 12 d), 8.9°C). Visual was measured every 24 h a* 6 during 48 period. Storage at 0°C...
There are two main beef cattle breed types:
Abstract Cattle feed yards routinely track and collect data for individual calves throughout the feeding period. Using such operational from nine U.S. years 2016–2019, we evaluated scalability economic viability of using machine learning classifier predicted mortality as a culling decision aid. The expected change in net return per head when predictions aid compared to status quo protocol having been pulled at least once bovine respiratory disease was simulated. This simulated ranged −$1.61...
