219 225 sheep were slaughtered under veterinary control in 1991. Examinations before and after slaughter revealed signs of, or lesions themselves in 61 919 animals (28.24 per cent). The number of unfit carcasses, assessed as less valuable and conditionally approved was 23 511 (10.72 per cent). Signs or lesions due to diseasses were found in 0.003 - 11.62 per cent of the sheep. Abscesses, contamination and hyperaemia (11.62 per cent), emaciation (6.04 per cent), liver fluke (3.3 per cent) and dropsy (1.59 per cent) were observed most often. Out of 49 regions, most sheep with signs or lesions were found in 13 regions (34-73 per cent), the majority of cases of emaciation and dropsy in 11 regions (11-21 per cent) and a high extensiveness of liver fluke in 10 regions (3-12 per cent).
About 29 000 horses at the age of 1—25 years of a body weight from 200 to 800 kg were slaughtered under veterinary inspection at 1990. Pre- and postslaughter examinations showed clinical signs and pathological lesions in 4627 (16.0%) horses. Among others were found natural death, slaughter at agony, partial bleeding, emaciation, purification, purulent foci, hyperemia, neoplastic lesions, abnormal odor, parasites. Neoplasms were found in 133 (0.45%) horses; predominated melanosarcoma, accidentally fibromas were found. As unfit were classified 683 (2.36%) horses.
In 943 933 pigs the following parasitic invasion were confirmed: trichinellosis in 10 animals (0.0014%), echinococcosis — 21 748 (2.47%), sarcosporidiosis — 118 (0.02%) and ascaridosis — 7 244 (0.77%). In 216 900 cattle cysticercosis was confirmed in 409 animals (0.14%) and fasciolosis in 14 635 (7.16%), liver echinococcosis was not noted. In 16 912 sheep 636 (2.71%) were found to have fasciolosis and 58 (0.31%) had echinococcosis, cysticercosis was not discovered. The analysis showed the considerable decrease of incidence of pig trichinellosis in comparison with the years 1947—1965. The incidence of bovine cysticercosis, however, is regular.
In 1994 more than 14 milion pigs have been slaughtered under veterinary inspection in Poland. During pre- and postslaughtered examinations pathological lesions were found in more than 5 milion (36.57%) of the carcasses, 90 356 (0.64%) of carcasses were evaluated as unfit, inferior or conditionally approved. The following have been diagnosed: tuberculosis, septicemia and pyemia, neoplasms, leukemia, emaciation, icterus, abnormal odor, incomplete bleeding, cysticercosis, trichinellosis, echinococcosis and other parasites, purulent foci and hyperemia. Tuberculosis-like lesions were diagnosed in 0.48% pigs. In 14 provinces from 10 to 97 cases of the trichinellosis (85% of all cases in Poland) were determined. The extensiveness of the trichinellosis ranged to 0.003%, S. miescheriana ranged from 0.15 to 1.02% and echinococcosis from 2.25 to 20.26%.
Оценивали содержание жировых запасных тканей в лошадиных тушах 3 качественных классов, разделяя годовой цикл получения туш на 2 периода: летний (1.04. — 30.09) и зимний (1.17. — 31.03). Выполнили измерения количества мелкого жира в основных элементах лошадиной передней и задней четвертины, жировой околопочечной ткани и оболочного жира. Установили зависимость между долей упомянутых жировых тканей и качественным классом туш. Отметили также высшую степень ожирения туш из зимнего периода. Основными элементами лошадиной туши с наибольшей долей мелкого жира являются ошеек и окорок.
The content of unsoaped substances, carotene and vitamin A in fats rendered from perinephral and mane fat tissues from car, casses belonging to three qualitative classes was examined. It was found that this fat is characterized by a similar level of unsoaped substances (an average for the perinephral fat 0.60% and for the mane fat 0.57%). A significantly higher content of carotene and vitamin A in the perinephral fat was found, an average 254.2 ug and 73.7 ug per 100 g of fat, respectively, compared to the mane fat (an average 161.4 ug and 62.6 ug per 100 g of fat, respectively). However, the fat gained from carcasses belonging to various qualitative classes does not differ significantly by the content of the examined constituents.
