The aim of the study was to determine the content of total protein, collagen, fat and water in country sausages of illegal production in comparison to sausages produced under permanent veterinary inspection. It was found that sausages produced according to the so called home method contained a lower quantity of protein and higher quantity of collagen and water when compared to sausages from legal production. Both types of sausages contain identical but high fat content.
During 5 years 1 321 075 pigs, 269 222 cows and calves, 9327 sheep and 479 horses have been slaughtered in the Kielce voivodship. Were evaluated as unfit 213 411 (13.3%) of the carcasses and organs, and 7019 (0.44%) as conditionally approved. The most frequent causes of losses in all animal species were pyogenic foci, contaminations and hyperemia, found in 57.76% of the pigs, 49.3% of the cows, 32% of the sheep and 17.9% of the horses. They were mainly the results of faults during long lasting and exhausting transport. The incidence of these changes decreased during the last 5 years. In pigs, great losses were caused by echinococcosis, especially liver echinococcosis (17.24%). The incidence of Trichinella spiralis diminished during the last 10 years in the Kielce voivodship. In cattle and sheep, high losses were caused by Liver fluke (36.7% and 24.4% respectively) but the extensiveness of the invasion diminished. Because of the small number of slaugh- tered sheep and horses conclusions concerning causes of losses can not be unequivocally established.
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.
