“…After the eradication of a foot‐and‐mouth disease outbreak in 2010, the swine producers implemented control programs to keep the area free from PRRS. However, there is a general hesitation to maintain a high biosecurity level because it is a management behavior that must be repeated daily (Zhang et al., 2013). Demonstrating a clear relationship between PRRS status and herd productivity could be a source of motivation for the farm in the studied region.…”

The objective of the present study was to assess the productivity of pigs to investigate the time‐dependent change in productivity and compare productivity according to breeding company group and porcine reproductive and respiratory syndrome (PRRS) status on commercial swine farms in southern Kyushu, Japan. Data used in the present study were 245 annual productivity records from 2014 to 2018 obtained from 72 farms. Average sow inventory was 481.2 sows. Mean numbers of pigs weaned per sow per year and market pigs sold per sow per year were 23.7 and 21.6, respectively. Pigs born alive per litter increased from 11.1 to 11.9 pigs from 2014 to 2018 (p < .05). Farms using domestic breeding companies had similar numbers in 2016 to those using international breeding companies, but fewer pigs in 2014, 2015, 2017, and 2018 (p < .05). Farms with an unknown or unstable PRRS status had fewer pigs born alive per litter and pigs weaned per sow per year than those with stable or negative PRRS statuses (11.2 ± 0.06 vs. 11.8 ± 0.08 pigs and 22.6 ± 0.38 vs. 25.0 ± 0.22 pigs, respectively; p < .05). These results can be used to establish feasible targets and standards of performance to identify problem areas and improve production.

“…A primary question of interest in this study is whether access to hog insurance will influence hog farmers' behaviour towards risk. Hog mortality rate is an important indicator of risk because the direct risk is unobservable (Zhang et al 2013(Zhang et al , 2016Pai et al 2015). Table 4, Part A, Column 2 shows that participation in insurance increases the hog mortality rate by 5.9 percentage points and the effect is statistically significant at the 1% level, indicating the presence of moral hazard.…”

Moral hazard is believed to influence farmers' production decisions and undermine the effectiveness of insurance programmes. In this study, a 2-year field experiment is conducted among hog farms in four townships in China to investigate the effects of a government-subsidised insurance programme on farmers' decisions and production outcomes. A joint estimation procedure combining propensity score matching with difference-in-difference is deployed to control for selection bias caused by observable and unobservable heterogeneity between treatment and control groups. We find robust evidence that this insurance programme has led to increased hog mortality rates, suggesting the possible presence of hazardous actions. Meanwhile, hog stock levels have remained unaffected by insurance participation, contradicting findings in previous studies. Furthermore, insurance participation is found to increase farmers' willingness to report animal diseases to governments, thereby facilitating government efforts to prevent and monitor outbreaks of animal disease epidemics.

“…A backyard producer either keeps the hogs in a pen in the backyard or lets the hogs run in the yard or village. For backyard producers, raising hogs is just one of several production activities; they also raise other livestock and poultry and, most importantly, farm crops (Zhang, Li, Liu, & Chen, 2013). As shown in Table 1, as of 1987-after agricultural reforms had been implemented for 10 years-more than 75% of farmers still raised hogs in their own backyards.…”
