Influence of pig farmer characteristics on improper use of veterinary drugs

Does a Traceability System Help to Regulate Pig Farm Households' Veterinary Drug Use Behavior? Evidence from Pig Farms in China

In China, there is a renewed interest in traceability systems as an efficient tool to guarantee pork safety. One of the pathways through which a traceability system can benefit consumers is by easing information asymmetry. However, past literature on the traceability system in China pays more attention to theoretical analysis and less to empirical analysis. Using a large-scale survey of pig farms in China, we investigate the effects influencing farmers' participation in the traceability system. Findings show that a traceability system can influence the safety of pork indirectly through its impacts on farmers' production behaviors. Another important finding is that unsafe pork is a result of non-standard use of veterinary drugs, and the traceability system works well for farmers by pushing them to take stricter safety measurements.

Assessing the role of internet in reducing overuse of livestock antibiotics by utilizing combination of novel damage control and 2-SLS approaches: Risk, responsibility, and action

Reducing farmers' overuse of livestock antibiotics is very essential to ensure food, environment, and public health safety. Currently, the "internet + " has emerged as a new initiative to stimulate the development of rural industries by alleviating farmers' information constraints, lack of skills, and knowledge deficiencies. However, very few studies have focused on this issue, and studies specifically focused on the role of the Internet in reducing the overuse of livestock antibiotics are still very limited. To fill this existing research gap, this study aims to investigate the role of the Internet in reducing the overuse of livestock antibiotics using data of 426 farmers based in three provinces, including the Hebei, Henan, and Hubei provinces of China. To analyze the collected data, we first employ a damage control model to estimate the marginal productivity of farmer use of livestock antibiotics and then use a two-stage least squares (2SLS) approach to assess the role of the Internet in reducing antibiotic overuse. The findings of our study show that the marginal productivity of farmers' use of livestock antibiotics by farmers is 0.0079 (approaching 0), indicating that the overuse of antibiotics has become the realistic response of farmers. Our results further reveal that the Internet has a significant inhibitory effect on the overuse of livestock antibiotics by farmers. The Internet can reduce the use of antibiotics by 1.3147 yuan/head by improving your knowledge and skills about antibiotics. The further findings of our study reveal that the educational level and organizational participation of farmers are also important driving factors to reduce the overuse of livestock antibiotics. Furthermore, the findings of this study validate the role of gender, age, and educational level in the non-linear effect of the Internet on farmers' overuse of antibiotics. In conclusion, the findings of this study provide insight for policy makers in motivating farmers to reduce antibiotic overuse by strengthening rural internet infrastructure, implementing skill training, improving supervision, and establishing an incentive mechanism for the standard use of antibiotics.

Antibiotic use in pig farming and its associated factors in L County in Yunnan, China

China has a long history of pig rearing, and it currently raises and consumes approximately half of the pigs in the world. Major improvements have been made in pig farming in China in the last four decades with the growing application of new livestock farming technologies. Among the new improvements, the use of antibiotics in pig farming is a common but not well‐documented practise. In order to understand the behaviour of the farmers regarding antibiotic use in pig farming, we conducted a household survey in four townships of L County in Yunnan Province, China, during August 2014 and April 2015. In this survey, 404 farmer households were interviewed using a questionnaire. Among the farmers interviewed, 89% reported easy access to antibiotics, 83.7% reported experience of self‐purchasing antibiotics, and 40.3% reported that they often used antibiotics in pig farming mainly for the prevention and treatment of pig diseases. These farmers identified 20 antibiotics that they had used in pig farming 6 months before the survey. Of these, 11 and 8 antibiotics have been categorised under ‘critically important’ and ‘highly important’ antimicrobial groups, respectively, by the World Health Organization (WHO), and 12 and 8 have been categorised under the ‘Watch’ and ‘Access’ groups, respectively, as per the 2019 WHO AWaRe classification of antibiotics. Factors associated with the behaviour of self‐purchasing antibiotics included types of farms, sources of antibiotics, and previous experiences of pig diseases: those who were smallholders, buying antibiotics from veterinary drugstores and village vets, and whose pigs had suffered diseases previously were more likely to self‐purchase antibiotics for their pigs. Farmers who cleaned their pigsties less frequently and those whose pigs had suffered from diseases used antibiotics more frequently as compared to their peer farmers.

This survey conducted in a county in Yunnan Province of China finds out that 83.7% of the farmers reported ‘self‐purchasing’ antibiotics for their pigs and 40.3% of the farmers expressed that they ‘often’ use antibiotics in pig farming with the major purposes being prevention and treatment of pig diseases.

Farmers' Willingness to Participate in Agricultural Product Safety Cogovernance and Self-Governance in Jiangsu, China: A Gender Perspective

ABSTRACT

Over the past two decades, the issues of quality and safety of agricultural products have attracted widespread attention in the People's Republic of China. The purpose of this study was to understand factors that influence farmers' willingness to participate in agricultural product safety cogovernance and self-governance based on a survey of farmers in Jiangsu Province, China. The results show that farmers' willingness to participate in the cogovernance and self-governance of agricultural product safety must be further improved. Among the sampled farmers, 28.93% consider that other farmers' improper agricultural product safety practices have nothing to do with them, and 17.25% claim that they would not want to take part in agricultural product safety trainings. Farmers with a weak appreciation for agricultural product safety hazards, a lack of food safety knowledge, and improper agricultural product safety practices are less willing to participate in cogovernance and self-governance of agricultural product safety. Female farmers are more willing to engage in agricultural product safety training than male farmers; however, their willingness to participate in agricultural product safety cogovernance is lower. The results of this study will be useful in improving food safety policy in China.

HIGHLIGHTS

Knowledge, attitudes and practices relating to antibiotic use and antibiotic resistance among backyard pig farmers in rural Shandong province, China

China is among the world's largest consumers of antibiotics for livestock, and the demand for meat protein continues to rise. Pig production takes place at a range of facilities, including backyard pig farms. The aim of this study was to describe the knowledge, attitudes and practices of backyard pig farmers concerning antibiotic use and resistance, and to observe household storage of antibiotics for use in pigs. We conducted a cross-sectional questionnaire survey among 271 rural residents with backyard pig farms in 12 villages in one town in Shandong province. The median number of pigs per backyard farm was 14, and 82 % (222/271) of participants reported not having had any training about raising pigs. Eighteen percent of participants (48/271) reported always or often adding antibiotics to feed to keep pigs healthy and prevent diseases, and a third (88/271) of participants believed that pigs should be given antibiotics when they stop eating. Thirty percent (82/271) reported having bought antibiotics in the previous year without having first spoken with a veterinarian. Antibiotics accounted for over half of all medicines stored (55 %, 197/358), and were observed in 31 % of all households (83/271). Less than half of participants (45 %, 37/83) from households in which antibiotics for pig use were found knew that they were storing antibiotics. The most common class of antibiotics stored for use in pigs was (Q)J01C beta-lactam antibiotics, penicillins (19 %, 37/197), followed by (Q)J01F macrolides, lincosamides and streptogramins (14 %, 28/197), and (Q)J01M quinolones (12 %, 25/197). These results provide important insights into how backyard pig farmers are using antibiotics in rural China and suggest potential targets for interventions to reduce unnecessary and inappropriate use.

Assessing the Linkages between Knowledge and Use of Veterinary Antibiotics by Pig Farmers in Rural China

Improper use of veterinary antibiotics (VAs) has led to antibiotic resistance and food safety issues that are harmful for sustainable development and public health. In this study, farmers' knowledge influencing their usage of veterinary antibiotics was analyzed based on a survey of 654 pig farmers in Funing County, China. A behavior probability model was constructed, and a Matlab simulation was used to evaluate the dynamic changes in farmers' behavioral choice regarding VAs use. The survey results showed that the 654 pig farmers' knowledge of VAs were relatively poor, along with a high occurrence of improper behavior. Specifically, 68.35% of the 654 surveyed pig farmers admitted their violation of VAs use regulations, while 55.50% among them overused and 24.31% among them misused VAs. The simulation results showed that the probability of improper VA use decreased with the increase in farmers' knowledge about VA use specification, and when farmers' knowledge about the hazards of VA residues increased. However, when farmers had a high level of knowledge about relevant laws and their penalties, there was still a high probability of improper VA use.
