Abstract

Ensuring the safety, health, and overall well-being of animals raised for nutrient is both an ethical obligation and a critical component of providing safety food products. The use of antibiotics for maintaining animal health has come under scrutiny in recent years due to the rising of antibiotic resistance globally. Some U.S. producers, especially in the poultry industry, have responded past eliminating their antibiotic use. The number of animals raised without antibiotics (RWA) is growing in the U.Due south., but there are concerns that RWA practices might negatively affect animal health and welfare. Therefore, the objective of this written report was to survey U.S. veterinarians and producers about their experiences and opinions regarding RWA production. Veterinarians, farmers, ranchers, producers, and other stakeholders involved in raising broilers, turkeys, swine, beef cattle or dairy cattle were surveyed. Of the 565 completed responses received, 442 self-reported as practicing veterinarians or producers. Merely over one-half of respondents reported having past or electric current experience with RWA programs. The main indicated reasons for raising animals without antibiotics were market driven; switching to RWA product was less ordinarily fabricated for health-related reasons, such as to reduce antibiotic resistance or to better animal health and welfare. Although respondents felt that RWA production has negative impacts on animal health and welfare, they overwhelmingly (>seventy%) indicated that the customer (retailer/eating place/food service) believes that animal and wellness welfare will be significantly improved. Veterinarians and producers indicated that RWA programs will increase product costs with questionable event on meat, egg or dairy consumer demand. Many respondents felt that in that location are times when the RWA characterization takes priority over fauna wellness and welfare. Respondents by and large felt that at that place was a need for increased auditing/assessment of animal health and welfare in RWA systems.

Introduction

Ensuring the health and well-being of animals raised for food is both an ethical obligation and a critical component of providing safety food products. Antibiotics are an important part of creature health programs, but their use has come under scrutiny considering of the rise of antibiotic resistance globally (ane–iv). Efforts have been made to improve antibiotic stewardship in animal agriculture, with different countries often adopting different approaches for enhancing the responsible utilize of antibiotics (i, v, six).

Some animate being producers, particularly within the U.Southward. poultry manufacture, take eliminated antibiotic use entirely and have adopted a "no antibiotics ever" (NAE) or "raised without antibiotics" (RWA) approach to animal production (7). In this paper nosotros volition refer to these programs as RWA. For the purpose of this paper, we define antibiotics broadly as antimicrobial drugs that have specific activity against bacteria. To be consistent with definitions in the U.S., this also includes ionophore antimicrobials. In RWA programs inside the U.S., "source animals cannot take been given antibiotics in their feed, water or by injections. This includes ionophores which are recognized as antibiotics by FSIS" (eight); ill animals needing antibiotic therapy must be removed from the RWA program. Animals that receive antibody therapy, too as their products, cannot exist sold nether an RWA label and must be marketed through a different distribution channel (8). Such circumstances frequently enhance logistical challenges and potential financial losses for the producer.

RWA programs are intended to supply customers, such as restaurants, grocers and other food service establishments, with meat, eggs, and dairy products that can be labeled as having never had exposure to antibiotics. Anecdotal prove suggests that retail customers and consumers presume that RWA and organic production will improve food safety and decrease antibiotic resistance in animals and humans while providing a more wholesome food product (ix). In a recent survey of consumers, 55% responded that they were extremely or very concerned almost antibiotic use in chickens when they purchase poultry products (ten). Respondents of this survey had some misunderstandings well-nigh poultry production practices. Although 60% of respondents considered themselves to be very or somewhat knowledgeable about the care of chickens, 75% believed that there are added hormones or steroids in craven meat (which has been illegal in the U.Southward. for many decades), and 71% believed that chickens raised for meat are housed in cages (which is untrue). Over half of survey respondents disagreed with the statement "Eliminating antibiotics leads to significantly more chickens dying of affliction."

Few reports exist comparison RWA to conventionally-reared animals, especially with respect to potential impacts on animal health, productivity, and welfare. A report was published in 2011 past Smith discussing his 12-year experience with RWA in broiler chickens (11), and some of his experiences included that these birds were more expensive to produce, due in function to stricter and more expensive nutrition requirements, and that the drug-gratis birds had a higher incidence of important diseases such as necrotic enteritis. More recently, Gaucher et al. (12) reported that drug-gratis production was associated with overall negative effects on key performance and gut health indicators (increased necrotic enteritis incidence, increased feed conversion, decreased daily weight proceeds, and decreased mean live slaughter weight), findings which are indicative of potentially negative impacts on overall fauna welfare. These outcomes can contribute to economic and environmental strain, as RWA programs endeavour to match production output of conventional programs.

In a recent randomized controlled trial evaluating the performance of pigs raised in antibody-free or conventional production systems following challenge with porcine reproductive and respiratory syndrome virus (PRRSV), investigators reported significantly greater mortality and removals in the antibody free group (57.98%) vs. groups treated with 2 different antibiotic regimes (20.94 and 24.89%, respectively), while average daily proceeds and feed conversion ratio were significantly better for the treated vs. antibiotic free pigs at finishing (13). This study was halted before completion and the pigs in the antibody-free group were treated with antibiotics due to welfare reasons. The authors conclude that "results bespeak that in a PRRSV-endemic setting involving bacterial co-infections, an ABF [antibiotic free product] strategy may leave pigs at considerable take a chance of exposure to severe clinical affliction and that judicious use of antibiotics can significantly improve beast wellness" (13).

A recent report compared three different broiler product systems: conventional, RWA, and non-medically important, wherein but antibiotics not considered important to human health are used (14). The report considered three important health conditions (eye ammonia burns, footpad lesions, and airsacculitis) which can be indicators of poor animal welfare. Pain from these conditions can lead to decreased feed intake and reduced weight gain. RWA production was shown to increase the run a risk and severity of all 3 of these health weather condition. Apply of not-medically important antibiotics diminished this risk and severity, but the risk was notwithstanding higher and disease more severe than that in conventional systems. Written report authors emphasized important limitations to their approach. First, the analyses do not show a cause and effect human relationship; in other words, the authors are non stating that raising birds RWA causes these conditions to become worse. Second, they emphasize that they did not analyze direction practices and other related on-subcontract variables. They state that shifting to RWA production necessitates changes to production, such as reduced stocking density and longer downtime betwixt flock production cycles in a barn. The authors concluded that many of the negative impacts of RWA production tin can potentially be macerated over time, but some might never be completely eliminated (14).

There is a need to understand the opinions, experiences, and perceptions of veterinarians, producers, and other partners in the food animal production chain on the topic of RWA and conventional animal production, including potential impacts on animal health and welfare. This current study was designed to begin the process of describing these perceptions along the production chain and is an of import step to informing more than directed, hypothesis-driven enquiry. The objective of this study was to survey veterinarians and producers direct involved in animal product about their experience and perception of the impacts (positive or negative) of RWA creature production on creature health and welfare. Specifically, this manuscript focuses on the furnishings of RWA production in the poultry, beefiness, swine, and dairy sectors on animal welfare, nutrient rubber, and cost of production.

Materials and Methods

Survey Blueprint

The survey was designed to collect data from veterinarians and producers involved with beefiness cattle, dairy cattle, swine, turkey, and broiler chicken product. The survey tool was developed by study co-authors and was reviewed by industry experts in each commodity for clarity, completeness, and usability.

Respondents to the survey were only allowed to respond questions for one of the five brute commodities, and this was based on the commodity that the respondent selected at the very beginning of the survey every bit the article with which they were most familiar. The overall survey included questions related to the respondent's RWA program experience, illness and welfare challenges inside the respondent's selected commodity, and experiences/beliefs about RWA impacts on animal health and welfare, food safety, cost of production, and antibiotic resistance. The survey was created for online assistants using spider web-based survey software (Qualtrics, Provo, UT, USA) and collected no identifying information from respondents. A consummate print-version of the survey is included in Information Canvass 1.

Survey Dissemination

A hyperlink to the online survey was distributed by various professional organizations and commodity groups such as American Association of Avian Pathologists (AAAP), National Chicken Council (NCC), National Turkey Federation (NTF), U.S. Poultry and Egg Association (USPOULTRY), American Association of Bovine Practitioners (AABP), Academy of Veterinarian Consultants (AVC), Fauna Agriculture Alliance, National Pork Producers Quango (NPPC), National Pork Lath (NPB), American Association of Swine Veterinarians (AASV), and Pig Comeback Company (PIC). These groups represent a variety of production types, including animal operations that raise animals conventionally with antibiotics, raise animals without antibiotics (RWA), and raise animals organically (which also qualify as RWA). Announcements were also fabricated at multiple professional person and article meetings and in primal trade journals. The survey was open up from Feb fifteen to March 23, 2018.

Data Analysis

This survey was intended to focus on fauna production within the U.S. Because of the potential for varying regulation, management practices and production systems to influence responses, data from international respondents were excluded from analysis. Data assay was conducted using standard statistical software (Stata 15.1, College Station, TX, U.s.a.). Respondents were categorized as having any experience with RWA production (RWA respondent) or having no experience with RWA production (Conventional respondent). Respondent role (e.g., veterinarian, producer) and RWA experience were compared with two-sample Wilcoxon rank-sum (Mann-Whitney) tests. Likert calibration graphs were prepared in R (15) using packages licorice and ggplot2 (sixteen).

Analyses in this paper focus on report questions related to the perception of each respondent of the potential impacts of RWA production on food safety, creature welfare, toll of product, demand for the respondent's animal poly peptide or product, and auditing of RWA production systems. Written report questions that focused on impacts on specific beast diseases, brute product, and affliction interventions are non addressed.

Results

Survey Responses

Five hundred and sixty-5 completed responses were received. About respondents were practicing veterinarians (northward = 248, 43.9%), producers (n = 214, 37.9%), and technical services professionals (n = 44, 7.viii%). Just over half of the respondents were working with (n = 241, 42.7%) or had previously worked with (n = 76, 13.five%) animals existence raised without antibiotics (RWA respondents). The remaining respondents (n = 248, 43.ix%) had no direct experience with RWA product (Conventional respondents). Ninety-five percentage of respondents (north = 536) were located inside the U.South. (Table 1). Twenty-seven international respondents were excluded from the analysis and are not included in the results that follow. For the following analyses, only producers and veterinarians with direct beast responsibilities are included (i.e., technical services professionals, academics, and government employees are excluded). Because only one turkey respondent had no experience with RWA production, no details of this response are provided. A total of 442 responses are included in the analyses that follow, although no information is provided nearly the single Conventional turkey respondent. These 442 respondents had completed all or well-nigh of the questions addressed in this manuscript; raw survey responses for these participants are included in Supplementary Tabular array one.

Respondents indicated the factors that contributed to their decision to participate in RWA product (RWA respondents) or reasons why they did not (Conventional respondents), and these responses are shown in Tabular array two. RWA respondents in all commodities most unremarkably identified market place-driven reasons for their decision to participate in RWA production. Specifically, the most common reason was "to fulfill a customer/customer request" (>60% across all commodities). Conventional respondents most commonly identified "concerns about negative impacts to animate being wellness and welfare" (>60% across all commodities) and "already raising animals in a responsible [antibiotic] use programme" (>50% across all bolt) as the most common reasons for not participating in RWA production.

Animate being Health and Welfare

Respondents were asked how they thought RWA production impacts animate being health and welfare. Across all five bolt, about RWA and Conventional respondents (>sixty% for all commodities) believed that RWA production would slightly worsen or significantly worsen animal wellness and welfare (Figure one). Inside the broiler, beef, and swine responses, significantly more Conventional respondents believed that RWA production would negatively impact animal welfare than did RWA respondents (P < 0.01, P < 0.01, and P < 0.05, respectively); there was no statistically significant difference between Conventional and RWA dairy respondents. Among RWA respondents, producers perceived less of a negative affect on fauna health and welfare than did veterinarians. Conventional veterinarian and producer perceptions were more than aligned, with both believing that the animal health and welfare affect would be more negative than the beliefs of their RWA counterparts.

Respondents were asked for their perception of customer (retailers, restaurants, or food services) opinions regarding how RWA product impacts animal health and welfare. The perception of the majority of RWA and Conventional respondents (>sixty% for all commodities) was that their customers believe that raising animals without antibiotics would slightly improve or significantly improve fauna health and welfare (Figure 2). This perception did not differ between RWA and Conventional respondents.

Food Rubber

Across all five bolt, the majority of RWA and Conventional respondents (>55% for all commodities except RWA beefiness respondents at 45%) believed that raising animals without antibiotics would have no impact, slightly worsen or significantly worsen food safety (Effigy 3). Within the broiler and beefiness responses, significantly more than Conventional respondents believed that RWA production would negatively impact food condom than did RWA respondents (P < 0.01 for broiler and beef). When stratified by role, in that location was a deviation of opinion in the RWA respondent grouping between veterinarians and producers, with RWA producers believing that in that location would exist less of a negative impact on food rubber when antibiotics are removed from the production system than did RWA veterinarians. Inside the Conventional group of respondents, veterinary and producer perceptions were more than aligned regarding the impact of removing antibiotics from the production system on food rubber.

Cost and Demand

Across all five commodities, most RWA and Conventional respondents (>80%) believed that raising animals without antibiotics would slightly or significantly increase the cost of production (Figure 5). Amidst those respondents that work with beef cattle, significantly more Conventional respondents believed that the cost of production would exist increased than did RWA respondents (P < 0.01); there were no statistically significant differences within the other bolt. Across all five commodities and RWA experiences, veterinarians were more than likely than producers to say that production costs would be increased.

Respondents were also asked how they think RWA production would bear on demand for their protein or production. Across all v commodities, almost RWA and Conventional respondents (>eighty%) believed that raising animals without antibiotics would have no affect or would slightly increase demand for their protein (Figure 6). Significantly more beefiness, dairy, and broiler RWA respondents believed that demand would be increased when compared to Conventional respondents (P < 0.05 for each commodity). Across all five commodities and RWA experiences, producers were more likely than veterinarians to say that the demand for the protein or product would be increased.

Characterization and Auditing

Respondents were asked whether maintaining the RWA characterization on a product e'er takes priority over flock/herd health and welfare. Specifically, survey participants were asked how strongly they agree or disagree with the statement: "There are times that maintaining an RWA label has priority over flock/herd health and welfare." Regardless of commodity type and RWA feel, responses to this question ranged from Strongly Disagree to Strongly Agree (Figure vii). A higher pct of RWA swine and dairy respondents Somewhat Agreed or Strongly Agreed with this statement than Conventional respondents, whereas the percentages were approximately equal for the beef and broiler chicken respondents. In full general, there were no major differences between the RWA and Conventional respondents when stratified by role. The analysis was repeated for the veterinarian respondents because the decision to utilize an antibiotic is fabricated by the veterinarian and thus the veterinarian respondents should have a better power to address this question of the survey. Regardless of commodity type and RWA experience, the veterinarian respondents again had a range of responses, including respondents who Somewhat Agreed or Strongly Agreed with the statement (Figure 8).

Respondents were asked whether more than stringent health and welfare auditing and cess is needed when raising animals without antibiotics. Across all five commodities and for both Conventional and RWA respondents, most respondents said that they Somewhat Hold or Strongly Concord with the need for more than auditing and assessment in RWA settings with the exception of the RWA broiler respondents; 32% of RWA Broiler respondents said that they Somewhat or Strongly Agree with this need (Figure 9). When stratified by role, Conventional veterinarians and producers were more than probable to agree with the statement than the RWA veterinarians and producers.

Discussion

This survey was designed to gauge veterinary and producer experiences and opinions regarding the impacts of RWA beast product on animal health and welfare. The primary reasons for raising animals without antibiotics were market place driven (Table ii), and in near circumstances, the decision to switch to RWA product was not made for health-comeback reasons, such as to reduce antibiotic resistance or to improve animal health and welfare. The RWA respondents generally felt that raising animals without antibiotics negatively affected animal health (Table 2 and Figure 1).

Veterinarians and producers indicated that RWA programs increase production costs (Figure v) simply were less certain that in that location would be a concomitant increase in consumer demand (Effigy 6). Although respondents largely felt that RWA production negatively impacts animal health and welfare, they overwhelmingly share the perception that the customer (retailers, restaurants or food services) believes that animal health and welfare will be significantly improved by raising animals without antibiotics (Effigy ii). Many respondents felt that there are times when maintaining the RWA characterization takes priority over animal health and welfare (Figures 7, ​ 8), and in full general, across all surveyed commodities, respondents saw a need for increased auditing and assessment of animal wellness and welfare in RWA systems (Figure ix).

Antibiotics remain an important component of health management in animal agriculture. The decision to apply an antibiotic, including the optimization of when, why, and for how long to administer the antibiotic can exist a complex and multi-faceted topic (17, 18). Equally is true in the varied settings and situations of man healthcare, approaches to improving antibiotic stewardship in animal agronomics, while effectively maintaining animal health and welfare, will differ amid commodity types, animal operations and veterinarians. A improve agreement of the risks and benefits associated with RWA production is needed, in addition to the documentation of changes that have been fabricated in RWA systems to successfully maintain animal health and welfare. This current study highlights areas where more information is needed.

This study has several key limitations. Starting time, the study utilized an bearding survey approach. Every bit is the case with most surveys, particularly those that maintain the anonymity of respondents, information technology is impossible to follow up with the respondents to verify their responses. Not knowing details of the exact individuals who participated in the survey also means that gauging the representativeness of the respondents to the overall population of livestock veterinarians and producers in the U.S. is a challenge. Notwithstanding, as the aim of this written report was to better sympathize U.Due south. producer and veterinarian experiences and perceptions surrounding the touch of removing antibiotics from the supply concatenation on animate being wellness and welfare, we believe that our use of listservs, species-specific veterinary professional organizations, and commodity group organizations provided a set up of responses that reverberate the overall U.S. fauna agricultural output systems. A 2nd possible limitation of this survey approach is the potential incentive of conventional respondents to enlarge the negative aspects of RWA production. When viewed side-by-side for each commodity, responses of the RWA and conventional participants are adequately consequent. Even though the RWA responses were based on the participants' experiences with RWA product, it would appear that the RWA and conventional respondents had similar perceptions of RWA production. Third, responses to questions regarding food safety might have been limited to stance for many of the respondents. The coauthors are uncertain how much food safety data or communication the producer and veterinarian respondents in this study receive regarding animals under their intendance. Some producers and veterinarians receive feedback from processing plants nigh the foodborne pathogen status of their animals, for example with respect to Salmonella, indicating that although the respondents might non exist experts on food prophylactic issues, they probable have some understanding of the brunt of certain foodborne pathogens in their animals.

Findings from this written report indicate that retailers, restaurants and food services might take a skewed perception of the impacts of RWA production. This is highlighted past the respondents' opinions that their customers believe that RWA production improves animal health and welfare (Effigy 2), in contrast to their own experiences and opinions (Effigy ane). Studies of food industry customers are needed to determine the basis for their perceptions of the RWA impact on beast wellness and welfare and to better understand the systems used to audit RWA production. Importantly, a detailed assessment of the auditing process implemented by the customers is essential to ensure that animal health and welfare are existence maintained in RWA systems (19). If audits are conducted infrequently, on a small number of premises, or rely exclusively on the opinions and reports of producers, it is possible that wellness and welfare problems would be missed. Findings from this study can hopefully be used to advance this chat.

The impacts of raising animals without antibiotics are not restricted to beast wellness and welfare. There are also potential effects on ecology sustainability and economical viability. One recent written report developed a simulation model to evaluate the impacts of RWA broiler production (20). They estimated that if the entire U.South. broiler industry were to shift to RWA product, impacts would include decreased edible meat, an increment in the number of broilers needed to run across current demand (680–880 meg more birds), associated increases in feed and h2o requirements (5.4–vii.6 million backlog tons and 1.nine–three billion excess gallons, respectively), and increased manure product (four.six–six.i 1000000 excess tons). The authors conclude that "eliminating the use of antibiotics in the raising of broilers may have a negative consequence on the conservation of natural resources as well as a negative economic event via increased prices to the consumer. Results suggest the need to communicate to consumers the supportive office that prudent, responsible apply of antibiotics for creature illness treatment, command, and prevention plays in the sustainable production of broilers." In a recent swine written report by Dee et al. (xiii), the authors calculated that the internet revenue per pig was on boilerplate a tertiary less for the pigs not treated with antibiotics ($33.81) vs. groups treated with antibiotics ($105.43 and $98.79) following challenge with porcine reproductive and respiratory syndrome virus (PRRSV).

Fauna health and welfare, and environmental and economical sustainability, are cardinal considerations when evaluating RWA production. However, the initial motivation of RWA product was the goal of reducing antibiotic resistance of man and animal health importance. Analyses comparing resistant bacteria and resistance gene loads on conventional and RWA farms or mathematical modeling studies have reported conflicting results (21–23). There is a demand for well-designed, longitudinal studies on farms that tin can simultaneously collect data on antibody utilize and resistance so that efforts to amend antibody stewardship can have resistance outcomes into account. There will e'er exist challenges of balancing creature wellness and welfare with RWA production, equally decisions of when to apply an antibiotic are non always clear, particularly when market forces are role of the decision to treat (24). However, overall improvements in animal welfare and a focus on non-antibiotic approaches to illness prevention could lead to a reduced need for antibiotics in the outset identify (11, 25, 26).

Based on the responses to this survey, RWA production does non appear to be driven by prioritization of animal health and welfare. Many respondents felt that in that location are times when the RWA label takes priority over animal health and welfare. This observation is concerning, as protecting animal wellness and welfare is a key component of the veterinarian's oath (27). If animals receive antibiotics to treat disease, the meat from these animals cannot be marketed RWA, and the producers must blot the added costs associated with RWA production. This might lead to pressures to sacrifice animal health and welfare to stay in an RWA programme. Equally stated by Karavolias et al. (13), "Policies aimed at eliminating or restricting the use of antibiotics in broiler production may come with potentially negative consequences with respect to adept animal welfare. A more than constructive policy approach should consider comprehensive animal intendance plans that incorporate good housing, management, and responsible antibody use, including the apply of ionophores. Policies aimed at informing the consumer on the positive role of access to antibiotics in supporting expert animal welfare while limiting risk of antibiotic resistance in humans are needed to address the current information gap." Veterinarians in beast agronomics must continue to develop antibiotic stewardship programs to optimize the option, dosing and assistants of antibiotics and to ensure that antibiotics are used merely when necessary.
