Similarities and Differences of Animal Welfare Perceptions between U.S. Cow-Calf Producers and the Public Abstract: The U.S. livestock industry is increasingly faced with pressure to adjust practices in response to societal concerns. A specific area of growing concern surrounds how production practices impact the welfare of farm animals. The objective of this analysis is to use best-worst scaling to determine which practices the U.S. public and cow-calf producers view as the most effective and most practical practices to improve the welfare of beef cattle in the U.S., and to determine similarities and differences in the public and producer views. Results indicate that both the U.S. public and cow-calf producers view provide access to fresh, clean feed and water appropriate for the animal’s physiological state, and provide adequate comfort through the use of shade, windbreaks, and ventilation assuring clean, dry, sanitary environmental conditions for cattle as the most effective and most practical practices to improve the welfare of beef cattle in the U.S. The practices which were viewed as the least effective and least practical were castrate male calves either within the first three months of age or with pain control, and dehorn/disbud calves either before horn tissue adheres to the skull or with pain control. Keywords: animal welfare, beef, best-worst scaling, cattle Similarities and Differences of Animal Welfare Perceptions between U.S. Cow-Calf Producers and the Public The U.S. livestock industry is increasingly faced with pressure to adjust practices in response to societal concerns. A specific area of growing concern surrounds how production practices impact the welfare of farm animals. Although consumers’ concerns and attention to animal welfare have increased recently, corresponding research and outreach efforts have not kept pace. The limited existing work has focused on gestation crates/stalls in the swine industry or alternative uses to laying hen cages in the poultry industry because these have been the focus of ballot initiatives and legislation. However, Tonsor and Olynk (2011) suggest that all livestock industries have experienced negative meat demand impacts from increasing media attention to animal welfare. Therefore, it is important to understand the economic implications for the beef industry of animal welfare concerns. This understanding starts with a benchmarking of existing awareness and perceptions of both producers and the public. An ongoing research and extension project funded by the USDA aims to provide exactly this benchmarking information by identifying U.S. consumer and cow-calf producer perceptions of animal welfare in the beef industry. One unique opportunity of this program is the ability to compare the U.S. public’s perceptions to those of cow-calf producers to identify market opportunities (e.g., aligning producer and consumer interest) and to identify potential threats (e.g., noting existing perception gaps that may result in calls for production changes). In short, this comparison will help document potential actions to better align wants and needs of the U.S. public with practices of beef producers. The objective of this analysis is to use best-worst scaling to determine which practices the U.S. public views as the most effective and most practical to improve the welfare of beef cattle in the U.S., which practices U.S. cow-calf Page 1 of 22 producers view as the most effective and most practical practices to improve the welfare of beef cattle in the U.S., and to determine similarities and differences in the public and producers views. Research Methodology Best-worst scaling is a methodology that presents individual survey respondents (either public member or producer in this analysis) with multiple choices and asks them to select one option as “best” and one option as “worst” of the multiple choices presented (at least three). Through multiple choice scenarios, a cardinal ranking of the attributes can be developed. Best-worst scaling questions are preferred to simple ranking or Likert-scale questions because individuals are required to make tradeoffs instead of simply rating the importance of each topic independently (Lusk and Briggeman, 2009; Wolf and Tonsor, 2013). This combats the issue of individuals marking all topics or issues as most practical, for example. Additionally, best-worst scaling nullifies the scale subjectivity of ranking questions; what is considered a “4” to one individual might equivalently be a “5” on another individual’s scale (Lusk and Briggeman, 2009; Lusk and Parker, 2009; Wolf and Tonsor, 2013). The pitfalls noted are avoided in best-worst scaling because there is only one way to respond to a question, a single choice (Lusk and Briggeman, 2009). Best-worst scaling has been used in health care preferences (Flynn et al., 2007 for example), epidemiology (Cross, Rigby, and Edwards-Jones, 2012), and in agricultural economics to evaluate consumer preferences for food values (Lusk and Briggeman, 2009) and dairy producer preferences for policies (Wolf and Tonsor, 2013). However, to the authors’ knowledge, no study has compared consumer and producer preferences on a food production issue including welfare of beef cattle. Page 2 of 22 The data collection portion of this project was three-fold. A national U.S public survey (n=1992, N=2000,) completed in December 2013 is representative of the US population1. Collaborating with BEEF magazine using surveys very similar to those provided to consumers, a total cow-calf producer mail survey response of 28.87% (n=433, N=1500) and online survey response of 1.91% (n=290, N=15,202) were obtained in December 2013 through January 2014. However, of the 723 producer responses, only 374 properly completed the best-worst questions (one answer as most and one answer as least for all choice scenarios shown) and are used in this analysis. Given multiple dimensions of possible changes in animal care provision it is important to consider the feasibility of implementing changes as well as to examine corresponding impacts on realized animal welfare. Accordingly, in this analysis, a split sample approach was used where one half of respondents (versions 1 and 2) assessed practicality while the other half assessed effectiveness (versions 3 and 4). That is, the “best” options were presented as “most effective” or “most practical” while the worst options were “least effective” and “least practical.” The design used in both the consumer and producer best-worst analysis was the same. To investigate the nine production practices in table 1, a total of 12 choice scenarios with six production practices each were needed for both the practical and effective scales2. To mitigate respondent fatigue, the 12 choice scenarios were randomly allocated to one of two blocks such that a given respondent only received six scenarios. An example best-worst choice scenario from this study using the effective scale is shown in figure 1. 1 Representative of U.S. population across age, gender, income, education, and state of residence Specifically, %MktBIBD in SAS 9.2 was used to identify a balanced, incomplete block design that was balanced with each production practice being included in eight scenarios and appeared in five scenarios with each of the other eight production practices. 2 Page 3 of 22 The nine production practices investigated (table 1) were selected following a multi-stage process. Narrowly, a longer list of production practices was identified from existing literature and current animal welfare protocols embedded in verification programs. Additional practices were considered following focus group discussions with livestock producers in related Extension meetings. Ultimately this longer list was shared by the authors with animal behavior and veterinarian experts to further refine the list to a set manageable for feasible investigation in our surveys. According to Louviere (1993), an assumption of best-worst scaling is the participant evaluates all possible pairs of items within the choices shown, and then will choose the pair that maximizes the difference (in importance in our application). If there are J items (or production practices in this analysis, 6 in each scenario), then J(J-1) best-worst combinations will be possible (or 6*5=30). The best-worst pair chosen represents the choice which maximizes the difference in importance. Following Lusk and Briggeman (2009) and Wolf and Tonsor (2013), let 𝜆𝑗 represent the location of 𝑗 on the scale of importance, and let the true or latent unobservable level of importance for individual 𝑖 be given by 𝐼𝑖𝑗 = 𝜆𝑗 + 𝜀𝑖𝑗 where 𝜀𝑖𝑗 is the random error term. The probability that the pair 𝑗, 𝑘 is chosen with production practice 𝑗 being the best and production practice 𝑘 being the worst out of a choice set with 𝐽 production practices, is the probability that the difference between 𝑗 and 𝑘 is larger than all the 𝐽(𝐽 − 1) − 1 other possible differences in the choice set. If the error terms are i.i.d. type I extreme value, then the probability described takes the multinomial-logit (MNL) form: 𝑃𝑟𝑜𝑏(𝑗 𝑖𝑠 𝑐ℎ𝑜𝑠𝑒𝑛 𝑎𝑠 𝑏𝑒𝑠𝑡 𝑎𝑛𝑑 𝑘 𝑎𝑠 𝑤𝑜𝑟𝑠𝑡) = 𝜆 −𝜆 𝑒 𝑗 𝑘 ∑𝐽𝑙=1 ∑𝐽𝑚=1 𝑒 𝜆𝑙 −𝜆𝑚 −𝐽 . (1) Based on the probability statement in equation (1), the 𝜆𝑗 parameters can be estimated by maximizing the log-likelihood function. Here, the dependent variable is 1 if the best-worst pair Page 4 of 22 is chosen by the individual, and 0 for the 𝐽(𝐽 − 1) − 1 other pairs of production practices. The 𝜆𝑗 estimated represents the importance of production practice 𝑗 relative to some other production practice that is normalized to 0 to prevent the dummy variable trap. The MNL assumes that individuals have homogeneous views for the production practices investigated. Given the likely diverse views on animal welfare broadly and individual production practices more narrowly, it seems likely that perceived effectiveness and feasibility would vary across respondents. Accordingly, to allow for respondent heterogeneity random parameters logit (RPL) models were also estimated (Train, 1998). Likelihood ratio tests reject the MNL model in favor of RPL models allowing preferences for all non-price attributes to vary normally. The remainder of this analysis reports results from these RPL models. Coefficient estimates from MNL and RPL models are not very intuitive for direct interpretation. Fortunately, a “share of preference” for each practice can be created that provides an interpretable estimate. The preference share is the forecasted probability that each production practice is chosen as the most important: ̂ 𝑠ℎ𝑎𝑟𝑒 𝑜𝑓 𝑝𝑟𝑒𝑓𝑒𝑟𝑒𝑛𝑐𝑒 𝑓𝑜𝑟 𝑝𝑟𝑜𝑑𝑢𝑐𝑡𝑖𝑜𝑛 𝑝𝑟𝑎𝑐𝑡𝑖𝑐𝑒 𝑗 = 𝑒 𝜆𝑗 ̂ ∑𝐽𝑘=1 𝑒 𝜆𝑗 . (2) The preference shares must sum to 1 across all nine production practices investigated. The value calculated in equation (2) represents the effectiveness or practicality of production practice 𝑗 on a ratio scale. For example, if one production practice has an effectiveness share that is twice that of the other, then the former is viewed as twice as effective as the latter. This share represents the probability that a production practice is more effective (or practical) than another production practice. Page 5 of 22 Using responses to the sets of best-worst scaling questions, both ordinal and cardinal rankings of the practices can be developed and compared across the producer and consumer groups. The resulting survey responses can be used to compare similarities between perceived effectiveness (e.g., improvement on welfare; potential demand side benefits) and practicality (e.g., feasibility of implementation; supply side impacts) that are critical to understanding economic implications of possible changes in production practices. Results and Discussion U.S. Public Tables 2 and 3 present the results for the U.S. public’s relative views on the effectiveness and practicality of the nine chosen practices to improve the welfare of beef cattle in the U.S., respectively. Table 4 and 5 present the parallel results for producers. The MNL models assume that all individuals have homogeneous views for the effectiveness/practicality of the production practices investigated. RPL A in all tables allows the views for each production practice to vary normally, and RPL B allows practices with insignificant standard deviations to have homogeneous views on effectiveness/practicality (zero standard deviations) while the other practices can have normally distributed heterogeneous views. Both RPL A and RPL B are uncorrelated RPL models. For the remaining presentation of results, the RPL B model will be used, as supported by the LR tests. In each of the models, the effectiveness and practicality were estimated relative to FCW. The negative coefficients in tables 2 and 3 reveal that the U.S. public view FCW as both more effective and more practical than the eight other production practices investigated to increase the welfare of beef cattle in the U.S. There was evidence of heterogeneity in views of effectiveness/practicality for all attributes except for C3M and DDC for both scales. Page 6 of 22 The preference shares have a more useful interpretation than coefficient estimates and thus are used to compare effectiveness or practicality. Overall, FCW has the highest probability of being ranked as the most effective and most practical with shares of 0.28 and 0.29, respectively (tables 2 and 3). Further, SWV (0.190, 0.169), and PTE (0.131, 0.140) have the second and third highest probabilities of being viewed as most effective or most practical. The two production practices which have the lowest shares of effectiveness or practicality are C3M (0.036, 0.045) and DDC (0.027, 0.031). Varying results across effectiveness and practicality arise for the production practices in the middle shares. The ranking of effectiveness shares for the middle four production practices were CTP (0.104), TPV (0.079), VET (0.76) and ADT (0.075). While for practicality the middle share rankings were ADT (0.097), CTP (0.091), VET (0.083), and TPV (0.053). Because the shares give relative rankings, FCW is viewed as two, three or more times as effective or practical than most of the other practices for improving the welfare of beef cattle in the U.S. U.S. Cow-Calf Producer The results from U.S. cow-calf producers are similar. There is evidence for heterogeneity in views for CTP, TPV, VET, and ADT in the effective scale (table 4) and SWV, CTP, TPV, VET, ADT, and C3M in the practical scale (table 5). Similar to the U.S. public respondents, all coefficients are negative indicating FWC is viewed as more effective and more practical than all other production practices to improve the welfare of beef cattle in the U.S. The cow-calf producers overwhelming view FCW as the most effective (0.394) and practical (0.507) practice to improve the welfare of beef cattle in the U.S. FWC is viewed as twice as effective as SWV (0.188) and more than three times as practical as SWV to improve welfare (0.151). Four practices, VET, PTE, CTP, and TPV have effective shares between 0.12 Page 7 of 22 and 0.06. On the other hand, PTE and VET have practicality shares around 0.11. Further, ADT, C3M and DDC are viewed as most effective by very few producers. In regards to practicality, CTP, ADT and C3M have very few producers view them as most practical and TPV has a near zero practicality share. Comparing public and producer views Figure 2 plots both producer and public shares in a 2x2 effectiveness and practicality space. The scale is normalized, meaning that zero indicates all the practices were viewed as equally effective or practical (0.111 share each). The measures in the upper right-hand (or first quadrant) represent those practices which are viewed as above average in both effectiveness and practicality terms. Those practices in the lower left-hand quadrant (or third quadrant) are viewed as low in terms of effectiveness and practicality. The relationship between effectiveness and practicality is nearly linear for both the public and producers. Although the reason for this linearity are not known, potentially, the U.S. public and producers do not distinguish between practicality and effectiveness. Furthermore, the correlation coefficient between effective and practical was 0.98 for the public and 0.97 for producers. The consensus among producers and the public is noteworthy. Both producers and the public view FCW and SWV and the most effective and practical methods to increase the welfare of beef cattle in the U.S. There is not as much agreement on other practices, but neither seem to view DDC and C3M as the most effective or practical practice to increase the welfare of beef cattle. The practices identified as both most effective and most practical, FCW and SWV, could be candidates for mandatory practices in animal welfare certification programs, policy promotions, or industry recommendations. These practices are likely already widely Page 8 of 22 implemented in the beef industry and thus would require less on the ground changes. Instead, more documentation and verification of these attributes could be warranted and communicated. Implications and Conclusions This analysis used the method of best-worst sampling to determine views on the effectiveness and practicality of production practices to improve the welfare of beef cattle in the U.S. Through the use of online and mail surveys both U.S. public members and cow-calf producers were surveyed. Effectiveness and practicality scales were developed from RPL modeling. It was found that FCW and SWV were viewed as both the most effective and practical practices to increase the welfare of beef cattle in the U.S. by the public and producers. However, DDC and C3M were viewed as the least effective and practical practices. Additionally, little distinction between practicality and effectiveness was found. Potentially, these results can be used to inform discussions on certification of an animal welfare assured label or in policy discussions. Given the diverse views likely to underlie a controversial issue such as animal welfare, it is important to further explore heterogeneity. Not only should heterogeneity be investigated across producers and the public but also within each group through the use of latent class modeling (LCM). By identifying heterogeneity across and within U.S. cow-calf producers and the public, niche markets can be identified. This will assist in aligning those in the marketplace who are concerned about beef animal welfare and are willing to pay a premium for products with desired attributes with producers who are willing to change their production practices to those sought after by said groups of consumers. These best-worst results could also be compared with data collected from producers regarding current production practices in place to assess gaps from on-the-ground practices. This will highlight the extent to which “real world change” may be required to alleviate growing Page 9 of 22 public concern. Also, a further investigation into the linear relationship between effectiveness and practicality may be warranted. Page 10 of 22 References Cross, P., Rigby, D., & Edwards-Jones, G. (2012).
