The effect of supplementation with thermally processed rape seeds on the improvement of flavor and taste values of lamb meat was investigated in the present study. The study was conducted on rams of Polish Merino breed. The lambs from the control group received the CJ mixture and meadow hay and the lambs from the experimental group additionally 200 g/head/day of thermally processed rape seeds (heated for 30 minutes at the temperature of 120^oC). After 90 days, all the animals were slaughtered and the samples of musculus longissimus dorsi were collected. Fatty acid profile was determined in intramuscular fat and sensory assessment of meat was also performed. It was found that the addition of thermally processed rape seeds resulted in a decrease in the content of saturated fatty acid (mainly stearic one C18:0) and an increase in the content of unsaturated fatty acids (mainly oleic acid C18:1) in intramuscular fat. The changes in the profile of fatty acids in intramuscular fat resulted in an improvement of flavor and taste values of lamb meat.

The objective of this study was to evaluate the effect of dietary conjugated linoleic acid (CLA) and false flax (Camelina sativa) seeds oil (FO), as a replacement for sunflower oil, on the performance of broiler chickens. Experiment was carried out on 96 chickens randomly divided into four groups – control: fed on the diet with sunflower oil (SO) and three experimental: fed on the diet with addition of CLA (2,86% starter, 4,32% grower) and fed on the diet with addition of CLA (1,43% starter, 2,16% grower) and SO or FO (1,43% starter, 2,16% grower). Daily weight gain, daily feed consumption, feed conversion ratio as well as final body weight were measured. No significant differences in growth performance were observed in the first period of experiment. In older birds dietary treatment with SO+CLA and FO+CLA daily weight gain, feed consumption and final body weight slightly increased. No significant differences in the values of analyzed parameters between SO, CLA and SO+CLA groups were observed. In conclusion, the results indicated that false flax oil and CLA can replace sunflower oil in chickens’ feeding, and demonstrated the effectiveness of false flax oil on the growth performance of broiler chickens.

Feline infectious anaemia (FIA) is a disease caused by a microbe called Mycoplasma haemofelis. Mycoplasma haemofelis is an extracellular parasite that lives on the surface of erythrocytes of domestic cats but is not limited to them (Felis catus, Felis domestica). In order to identify the parasite in blood, a blood smear test cat is carried out by means of Romanowski staining methods acridine orange staining (which stains bacterial DNA and RNA) and direct fluorescent antibody staining methods. The aim of this study is to show that the performance of blood smearing in suspected animals is useful for the FIA diagnosis. The result showed that it is impossible to make a definite diagnosis of FIA on the basis of clinical symptoms as it was found in only 80% of the cats with the symptoms of apathy, loss of appetite, cachexia, fetor ex ore, lymph nodes enlargement, mucosal ischaemia, mucosal icterus, arouse a much suspicion of the disease and may call for a further procedure. Performance of blood smearing seems to be a good diagnostic method in the case of the FIA disease, yet, it should be carried out at least three times at interval over several days.
