Health status of slaughtered animals as indicated by postmortem inspection at slaughterhouses

Abstract

The study focused on the comparison of health of cattle, pigs, sheep, goats, rabbits, poultry and ostriches slaughtered in slaughterhouses in the Czech Republic based on the occurrence of findings detected during a postmortem veterinary inspection in the period from 2010 to 2019. The level of health was expressed as the so-called PA index obtained by the ratio of the number of findings to the total number of observations (15) during the pathoanatomical examination in the slaughterhouse multiplied by one hundred. Mammals (cattle, pigs, sheep and goats) generally had a higher PA index than birds (domestic chickens, turkeys, ducks, geese, ostriches), with the exception of kids and rabbits. The highest PA index was found in cows (15.13) and piglets (12.18); whereas the lowest PA index was found in broiler chickens (0.102), rabbits, and geese (both 0.14). In poultry, the PA index values were below 1, with the exception of laying hens (PA index 2.165). A higher PA index was found in a group of adult animals (the PA index ranged from 2.17 to 15.13) and groups of young animals culled from farms (the PA index ranged from 10.79 to 12.18) than in fattened animals (the PA index ranged from 0.10 to 5.32). A comprehensive overview of the health condition of slaughtered animals enables the farmers, veterinarians, transporters and slaughterhouse operators to take appropriate and precisely targeted preventive measures, thereby increasing the animal welfare and health in the future while reducing the incidence of carcass damage.
