The aim of the study was to analyze the results of sanitary and veterinary examinations of rabbits carried out by the Veterinary Inspectorate in slaughterhouses in Poland in 2010-2018. In this period, 8,980,660 rabbits were examined. Lesions and quality deviations were found in 42,779 carcasses, i.e. 0.48% of all carcasses examined. The most frequent causes of the rejection of the carcasses and internal organs of the rabbits examined were sepsis and pyaemia (36,369 cases), followed by excessive emaciation (1,686 cases), upper respiratory tract disease (1,655 cases), other causes not specified by name (1,438 cases), and coccidiosis (1,318 cases). Abnormal exsanguination (303), parasitic diseases other than coccidiosis (67), infectious diseases (14), and leukemia (2) were much less often the cause of rejection. During the period analyzed, there was a decrease in the number of cases of coccidiosis (except in 2017) and other parasitic diseases, but there was a several-fold increase in the occurrence of sepsis and pyaemia (in the years 2015-2018). Compared with the results of veterinary and sanitary examinations of rabbits in 2000-2010, there was an increase in the number of rabbits slaughtered and a reduction in the percentage of carcasses with pathological changes and carcasses deemed unfit for consumption. In the years 2010-2018, there was also an increase in the number of cases of sepsis and pyaemia and a significant decrease in the percentage of parasitic diseases (mainly coccidiosis).
Within 9 years (1986-1994) 52 926 790 dead fowl and their internal organs were assessed. Out of 32 815 539 chickens the following qualitative changes were observed: hyper leanness in 95 615 animals (0.29%), bad exsanguination in 22 000 (0.068%), sepsis and pyemia in 1667 (0.005%), decomposition and chicken scalding in 15 504 (0.047%). Out of 2 340 752 hens assessed hyper leanness was observed in 9693 (0.41 %), bad exsanguination in 2360 (0.10%), sepsis and pyemia in 752 (0.032%), decomposition and scalding in 1704 (0.072%). Out of 17 770 499 turkeys examined hyper leannes was noticed in 17 737 birds (0.099%), bad exsanguination in 13 960 (0.078%), sepsis and pyemia in 6669 (0.037%), decomposition and scalding in 2829 (0.0159%). The analysis of the results indicated that the frequency of lesions and unsatisfactory quality were not high and hyper leanness was the most often noted deviation from standart norms.
The aim of the study was to analyze the results of post mortem examinations on slaughtered rabbits conducted in the years 2000-2010 by the national Veterinary Inspection in rabbit slaughterhouses in Poland. During the studied period over 5.6 million rabbits were slaughtered. In 280,686 carcasses quality changes on account of morbidity occurred, which constitutes 4.94% of the examined carcasses. Of these carcasses 59,428 were considered unfit for consumption, i.e. 21.17%, and 1.05% of all carcasses, which were examined after slaughter. The most common diseases confirmed were parasitic invasions, primarily coccidia (65.13%). However, the most common reasons for considering carcasses as unfit for consumption were bacterial diseases (sepsis and pyemia - 34.93%) as well as coccidiosis (28.96%). The most frequent qualitative changes of rabbit carcasses were excessive thinness (2%) or insufficient bloodlessness (1.64% of the confirmed changes). All of the carcasses in which these changes have been confirmed were considered unfit for consumption. Starting from 2006 the percentage of carcasses in which post-slaughter changes were confirmed has systematically decreased, while from 2008 the same concerns carcasses unfit for consumption. At the same time, the percentage of carcasses considered unfit for consumption from among the animals with confirmed qualitative changes after post-slaughter examination decidedly increased. This proves the good health of the rabbit population raised for slaughter in Poland, as well as its proper sanitary-veterinary control, which guarantees the high quality of the meat gained from it.
