Abstract: (1081 Views) |
In this research, 30 farms from five cities of Markazi province were assessed and biosecurity audited. The forms for examining danger crossings, mechanization equipment used on the farm, and biosecurity audit (standard of the country's veterinary organization) were completed for each farm. The relationship between mechanization and the level of biosecurity was done using correlation analysis and a semi-quantitative model was used to assess the probability of risk. The obtained results showed the maximum probability of risk with a numerical index of 0.40 for the trout farms of Arak and Farahan and the maximum mean probability of risk (± standard error) with 0.205±0.022 in Farahan city and the minimum probability of risk with a numerical index of 0.03 for Arak and Shazand, the mean of risk probability (± standard error) was obtained with 0.15±0.016 in the trout rearing farms in Shazand. The mean probability of risk at the level of all the selected farms of certain studied cities of Markazi province was calculated as 18.009 ± 0.009, which indicated that all the selected farms studied were in the category of medium possible risk (level B). In order to test the relationship between two variables, the probability of risk and the degree of mechanization from Pearson's correlation test were used. No significant correlation was observed between the probability of risk and the degree of mechanization (P = 0.41, n = 30, and r = 34). As a result, from the statistical point of view, it was determined that the variables of risk probability and the degree of mechanization were not related to each other. This component was also similar for production capacity and mechanization level. The obtained results showed that due to the weakness of biosecurity equipment in the mechanization of dual-purposed agricultural farms for fish farming in the Markazi province, the risk in some of these farms has increased to the level of being placed at probability of high risk (level C), which can easily reduce the risk in these farms significantly by taking necessary measures and establishing biosecurity plans. |
