{ZONA} system is dedicated to IT tool for making evaluation of education process. The efficiency of the teachers evaluation process using {ZONA} system has undoubtedly increased. Considering both: the time of preparing evaluation reports and number of staff engaged in that process there has been a significant improvement of efficiency. The result of the evaluation survey is surely highly important for each of the teachers. One can use the information included in the report to improve it's teaching skills. That's why it is very important that every teacher receives as soon as possible the evaluation report that has been prepared especially for that teacher, and that is what {ZONA} system does. On the bases of: each and the main categories ranks and comments placed by students each teacher is able to analyze and enhance the way of teaching. Every teacher who is constantly trying to improve it's teaching skills will have the guideline what way to follow in order to get to become perfect. The way of gathering, processing storing and distributing surveys seems to be optimal, concerning costs and benefits but it will be improved if any necessary.

The article presents data of a computer analysis of the antibiotic resistance patterns and results of evaluations of the level of antibiotic resistance of Gram positive and Gram negative bacteria isolated from pigs in 1985-1990, performed in diagnostic laboratories of the Centers of Veterinary Hygiene in Białystok, Katowice, Olsztyn, Poznań, Warszawa and Wrocław. The resistance of Escherichia coli (non-haemolytic, haemolytic and β-haemolytic), Pasteurella multocida, Salmonella typhimurium, S. choleraesuis, S. enteritidis, Salmonella of the В group, Streptococcus β-haemolyticus against ampicillin, chloramphenicol, erythromycin, neomycin, nitrofurantoin, oxytetracycline, penicillin, streptomycin, sulphonamides, sulphonamides + TMP and TMP was analyzed. A high level of resistance of E. coli isolates (54-97%) to ampicillin, oxytetracycline, sulphonamides and sulphonamides potentiated with TMP and a low level of resistance (26-42%) to nitrofurantoin, neomycin, streptomycin and chloramphenicol were determined. P. multocida isolated were characterized by a high level of resistance to sulphonamides and sulphonamides potentiated with TMP (61-85%) and a low resistance to oxytetracycline (32%). Salmonella sp. was characterized by a very low resistance (51-74%). S. β-haemolyticus had (62%) and a lower resistance to streptomycin (46%), penicillin (24%) and nitrofurantion (23%).

The present study aimed to establish the effects of grass meal and duration of feeding it on the carcass chemical composition, and on the intramuscular fat (IMF) concentration and fatty acid composition of the musculus longissimus dorsi (MLD) in 48 pigs growing from 25 to 105 kg body weight (BW). The pigs were fed a commercial diet (C) or a diet containing 20% grass meal (GM). Changes of the chemical components in the carcass and intramuscular fat of the MLD were estimated using the comparative slaughter method. The animals were slaughtered at 50, 80 and 105 kg BW. Pigs consuming the grass meal diet grew more slowly (by 9.2%; P = 0.007), but they had similar amounts of protein, ash and water (average 9.9, 1.8 and 35.9 kg, respectively) and less (by 18.4%; P = 0.001) fat in the carcass compared with those fed the commercial diet. Pigs fed the GM diet had approximately 20% less IMF (P = 0.003), lower (P = 0.024) concentration of saturated fatty acids (SFA) and higher (P = 0.047) concentration of polyunsaturated fatty acids (PUFA) in the MLD than pigs fed the C diet. The GM pigs also had a higher concentration of C18:3 n-3 (linolenic acid; P = 0.047) and tended to have a lower (P = 0.091) C18:2 n-6/C18:3 n-3 ratio in the MLD than C pigs. The PUFA/ SFA ratio remained low, but was more beneficial in the pigs fed the GM diet compared with those fed the C diet (0.40 vs 0.35, respectively; P = 0.102).

The effect of fat content in primal cuts of pigs fed diet enriched in the mixture of linseed (2%), rapeseed (0.5%) and fish (0.5%) oils on healthpromoting properties of pork was investigated. Twenty-four crossbred (♂Duroc × ♀(Polish Large White × Danish Landrace)) pigs were fed an experimental diet restrictively from 60 to 105 kg of body weight. After slaughter the right-half carcass was dissected into neck, loin, ham, shoulder and belly. Based on the fat content in the Longissimus thoracis et lumborum muscle pigs were divided into two groups – with low intramuscular fat content (LMF; below 1.10%) and with high intramuscular fat content (HMF; above 1.10%). Meat from primal cuts was characterized with SFA (saturated fatty acids)/PUFA (polyunsaturated fatty acids) and n-6/n-3 PUFA ratios for meat with health-promoting properties according to WHO. Belly and neck of pigs from both groups, and loin and shoulder of HMF pigs met the European Union recommendations for human nutrition for products which are considered as either n-3 PUFA sources or products with high n-3 PUFA content. The particular fatty acids content is positively related with the fat content in primal cuts; however this effect is more pronounced in meat with a greater fat content

The relationship between blood lipid indicators, subcutaneous and intramuscular fat contents and with the concentration of omega-3 fatty acids in the musculus longissimus dorsi (MLD) was investigated to search for biomarkers specifically associated with one of these relationships. The study was carried out on 32 gilts growing from 60 to 105 kg body weight (BW). The pigs were fed control (C) or experimental diets (L, M and H) in which 10% of metabolizable energy of diet C was replaced by 3.5% of fat mixtures that introduced in the different ratios of omega-3 fatty acids into the diets. The pigs were slaughtered at 105 kg BW and the serum concentrations of total protein (TP), triglycerides (TRIG), total cholesterol (CHOL), and high-, low-, and very low-density lipoproteins (HDL, LDL, VLDL, respectively) were determined. Backfat thickness, meat content in the carcass, and the fatty acid composition of MLD were estimated. Increased omega-3 fatty acid contents in the diet resulted in decreased concentrations of blood lipid indicators. TRIG displayed a significant correlation with meat content and backfat thickness in the carcass (r = –0.54, P < 0.01 or r = 0.43, P < 0.05). Also, a significant correlation was found between TRIG in the blood and the concentration of eicosapentaenoic and docosapentaenoic acids in the MLD (average r = –0.56, P < 0.01) and between CHOL in the blood and the concentration of linolenic acid in the MLD (r = –0.61, P < 0.01). Although the presented relationships were shown to be statistically significant, these blood lipid indicators should be viewed with caution as biomarkers specifically associated with carcass fatness.

The experiment was performed according to a 2 x 2 factorial design with breed and level of nutrition as factors affecting fat metabolism in pigs. Two groups of gilts, each comprising 4 Polish Large White (PLW) and 4 Synthetic Line 990 (L990) animals, were fed from 60 to 105 kg body weight on the experimental diet at 85% or 95% of assumed ad libitum intake. The diet contained 2% of linseed, 0.5% rapeseed and 0.5% fish oils as the source of n-3 fatty acids (FA). The carcass protein content was smaller and backfat thickness greater in L990 than in PLW pigs. Also the intramuscular fat content in the biceps femoris (BF) and longissimus dorsi (LD) muscles and their contents of total FA, saturated fatty acids, monounsaturated fatty acids (MUFA) and polyunsaturated fatty acids (PUFA) were higher or tended to be higher in L990 than in PLW pigs, the differences between the breeds being more pronounced in the BF muscle. The n-6/n-3 PUFA ratio tended to be lower in the LD muscle, whereas in the BF muscle, it was lower in L990 than in PLW pigs. Feeding at the 85% level resulted in smaller backfat thickness and carcass fat content in animals of both breeds. Gene expression of stearoyl-CoA desaturase in both muscles was higher in L990 pigs, which could have resulted in the higher MUFA and PUFA contents in this breed. Gene expression of fatty acid-binding protein 4 and peroxisome proliferator-activated receptor were affected both by breed and feeding level only in the BF muscle.
