Objective of this paper was to present results of investigation of different genotypes on quality of pig carcass and meat. Dissection of four main carcass parts was performed (n=67) in order to present share of tissue in main carcass parts. The quality of pig carcasses was investigated on three genotypes: Swedish Landrace (SL/SL) and two hybrid combinations with Durroc and Pietrain (VJ/LW x SL/SL) x D and (VJ/LW x SL/SL) x P. Meat yield of pig carcass sides was determined by partial dissection and for Swedish Landrace it was 51,30%, and for three breed combination with Durroc 56,04% and for three breed combination with pietrain 58,55%. It was established that genotype of pigs in fattening influenced the quality of meat, since the three breed combination with Pietrain (genotype C) had the lowest share of free fat, the poorest colour and the lowest WBA, and hihger share of ashes compared to results obtained for other genotypes (1,22; 0,27; 46,50 and 1,17).

Objective of this research was to present and compare results of the research of the effect of two fattening methods, on deep litter and conventional method (without litter). Slaughter properties have been determined with special focus on distribution of certain tissues in pig carcasses fattened in two different ways. Research was carried out on meat, fattening pig breeds - Swedish landrace. Research included 115 fatteners from single farm in Vojvodina. Depending on the housing conditions, two groups were formed: first group - group I (60 heads in group) was housed on deep litter, and the second - group II (55 heads in group), without litter. At the end of the trial, pigs were slaughtered and dissection was performed on cooled (+4?C) left carcass sides and meat yield determined using the method of partial dissection (Walstra and Merkus, 1996). Carcass sides were cut in 12 parts. Based on the meat quantity in four main carcass parts: leg, shoulder, back-loin part (BLP) and belly-rib part (BRP), which contain 75% of total musculature mass and mass of tenderloin of carcass side, meat percentage in carcass sides was calculated according to formulation (Manojlovic Danica et al., 1999). Fatteners housed on deep litter had statistically significantly (**p<0.01) lower mass of cool carcass sides (38.38 kg) compared to fatteners housed without litter (40.90 kg). Higher absolute and relative shares of leg (10.22 kg and 25.02%) were established and higher absolute yield of shoulder (5.35 kg ) in fatteners housed in boxes without litter (II group). Yield of muscle tissue in leg, shoulder, BLP and BRP was higher in fatteners of the II group (without litter) compared to pigs fattened on deep litter, and also statistically highly significant differences were established in share of muscle tissue in shoulder (**p<0.01) and considerable differences in regard to share of muscle tissue in BRP (*p<0.05). Meat yield of pig carcass sides was determined by method of partial dissection, for fatteners housed on deep litter it was 47,92%, and in case of fatteners housed without litter it was 53.89%. Established differences were very significant (**p<0.01).

In this paper quality of carcasses/carcass sides and meat from 5 different pig genotypes was comparably evaluated. Quality of carcass sides was evaluated prior to slaughtering in vivo (SONOMARK SM 100 M), early post mortem on slaughter line (FOM), by method of two points (ZP - ZWEIPUNKT) as well as method of partial dissection on cold left carcass sides according to EU recommendations. By analysis of obtained results it can be concluded that fatteners of type E (LW x SL) x P had the highest meat yield in carcass sides (61,90; 62,40; 58,85 and 58,89%) by any other mentioned methods of evaluation compared to average meat yield in carcass sides of other investigated genotypes. Average yield of muscle tissue in carcasses of pigs of E genotype (LW x SL) x P (58,89%) established by method of partial dissection was statistically considerably higher (*p<0,05) than the average (56,06%) meat yield in carcasses of pigs of genotype D, very significantly higher (**p<0,01) than average (57,01%) meat yield in carcasses of pigs of genotype C and very highly significantly higher (***p<0,001) than average (51,30%) meat yield in carcasses of pigs of genotype A. The quality of meat was also investigated comparably by determining its technological quality and chemical composition of MLD in investigated genotypes of pigs. Technological quality and chemical composition of MLD demonstrated significant (*p<0,05) differences in WBC and pigment content between genotypes B and C and B and E. Average values for content of ashes and share of pigment are in accordance with average values which characterize muscles of normal traits. By analysis of obtained results we conclude that fatteners of genotype E (LW x SL) x P had the highest meat yield in carcass sides (61,90; 62,40; 58,85 and 58,89%), but quality was slightly decreased which indicates need for further improvement of meat quality.

Major qualitative parameters of Landrace pig carcasses are presented in this paper. Phenotypic correlation between carcass quality indices and meat yield of carcass sides was investigated. Fatteners included in this research (117) were reared in non-conventional conditions, on deep litter, and as litter straw was used. Meat yield of pig carcass sides was evaluated on the slaughter line using the 'two point' method (Dzinic et al. 2004) and mathematical model using FOM-device (defined by Petrovic et al. 1996). Meat yield of carcass sides estimated using FOM was 56,29%, and by method of 'two points' 53,16%. Of basic quality parameters of pig carcasses the strongest correlation assessed using FOM device was established between meat yield of carcass side and thickens of fat tissue - LF and RF, and using the method of two points, between meat yield of carcass side and thickness of fat tissue - X1 i X2. Established correlations were negative, strong and statistically significant (-0,85**; -0,87**and -0,97**; -0,77**). Results of the assessment of quality of pig carcasses obtained using method of two points (53,16%) and by instrumental method on right carcass sides using FOM device (56,29%) differed, which indicates need to develop new equations for evaluation/assessment of share of muscle tissue in pig carcasses. .

The comparative quality evaluation of sides and meat was performed after several years of selection of Large Yorkshire (LY) and Swedish Landrace (SL) pigs. The quality of carcass sides e.g. meat yield in sides, was determined in-vivo, using the PIGLOG 105, on the slaughter-line according to Regulation and using the FOM device on a number of pig carcass sides of LY and SL breed(n: LY = 48; SL = 39), and after cooling, partial dissection of left sides was applied according to procedure recommended in the EU, on a smaller number of pure breed sides (n: LY = 18; SL = 17). The investigated selection model in pure breed animals yielded rather good results regarding halves quality of both races (% of meat determined by partial dissection: LY = 57,9; SL = 57,4), while the average meat quality (M. semimembranosus) on the basis of technological characteristics (pHi, pHu, WHCu and colouru) of both investigated races was somewhat poorer and corresponded to RSE quality.

The main direction of state policy regarding the guaranty safety and quality of animal products is the creation of conditions that are safe for human health during the production and sale of food raw materials. According to current legislation of Ukraine responsibility for the safety of food products placed on the manufacturer but government control plays an important role. This is especially true today, when almost 69.5% of meat is produced in private home farms. It is mainly sold in the agro-industrial markets. The State Service of Ukraine for Food Safety should perform the conditions of modern European regulation and base its activities on the basis of risk assessment. One of the risks are parasitosis, as their negative effect affects the health of millions of people in the world. In this cjnnection the purpose of the study was to analyze the dynamics of the identification of invasive diseases at the stages of slaughter of animals and the sale of slaughter products. Research material was reporting on veterinary medicine (Form № 5-vet and Form № 6-vet) of a number of districts of Odessa region for 2014‒2017. It was founded that 75943 animals were slaughtered in 2014‒2017: 91.18% pigs, 8.14% cattle and 0.68% sheep. The analysis of the dynamics of slaughter, depending on its location, showed that from 41.85% to 99.81% of animals were slaughtered at courtyard. According to the results of veterinary-sanitary control and supervision during the slaughter for the studied years there were no cases of diseases. It was founded that 22617 animal’s carcasses came to the agrofood markets of the regions for the years 2014‒2017, among which 89.56% were pig carcasses, 10,11% cattle carcasses and only 0.33% sheep. According to results of veterinary-sanitary examination in the conditions of SLVSE in the markets, specialists established 351 cases of diseases. In the study of pig carcasses 246 cases of diseases were detected: among them of non-communicable (45.93%) and invasive (54.07%) etiology (echinococcosis). Luring the expertise of cattle carcases was founded 96 cases of diseases: – dicroceliosis (98.96%) and exinococcosis (1.04%); during the expertise of sheep’s carcases – 9 cases of diseases – dicroceliosis (66.67%) and exinococcosis (33.33%). Considering that during the reporting period, according to the results of veterinary-sanitary control and supervision during the slaughter of animals, no cases of diseases were detected, but at the same time the number of cases of detection of invasive diseases during veterinary-sanitary examination in SLVSE on markets constantly increases risk management at the stage of slaughter can be considered not sufficiently effective. Also, the results of our research indicate that the current system for managing the safety of slaughter products is still based primarily on the study of the final product. It does not take into account all possible risks at the previous stages of production. This system can’t fully guarantee to consumer safety of products.

The removal of a non-steroidal anti-inflammatory drug (NSAID) diclofenac sodium salt (DCF, C14H10Cl2NNaO2) from water in two hybrid systems coupling photolysis or photocatalysis with direct contact membrane distillation (DCMD) is presented. A UV-C germicidal lamp was used as a source of irradiation. The initial concentration of DCF was in the range of 0.005-0.15 mmol/dm3 and the TiO2 Aeroxide® P25 loading (hybrid photocatalysis-DCMD) ranged from 0.05 to 0.4 g/dm3. Regardless of the applied hybrid system and the initial concentration of DCF, the model drug was completely decomposed within 4h of irradiation or less. Mineralization was less efficient than photodecomposition. In case of the hybrid photolysis-DCMD process the efficiency of TOC degradation after 5h of irradiation ranged from 27.3-48.7% depending on the DCF initial concentration. The addition of TiO2 allowed to improve the efficiency of TOC removal. The highest degradation rate was obtained at 0.3 gTiO2/dm3. During the process conducted with the lowest DCF initial concentrations (0.005-0.025 mmol/dm3) a complete mineralization was obtained. However, when higher initial amounts of DCF were used (0.05-0.15 mmol/dm3), the efficiency of TOC degradation was in the range of 82.5-85%. The quality of distillate was high regardless of the system: DCF was not detected, TOC concentration did not exceeded 0.7 mg/dm3 (1.9 mg/dm3 in permeate) and conductivity was lower than 1.6 μS/cm.

Abstract This paper studies how the congestion of its editorial process affects an academic journal. In a publishing game played by researchers and editors, we assume that quality screening by editors depends on their ability to properly process the flow of submissions. When too many papers arrive, this ability declines and editors may reject good papers or accept papers with little contribution to scientific knowledge. In this game, a separating equilibrium always exists in which only good researchers submit their papers to the journal. Each paper is accepted and the quality of the journal reaches its highest level. However, when the researchers’ reward for each publication exceeds a given threshold, two hybrid equilibria are also feasible. In these equilibria, authors of low-quality papers submit their papers to the journal and, as the flow of papers exceeds the editors’ capacity of perfect assessment, the selection process becomes imperfect. This creates an opportunity for authors to submit poor quality papers, a behaviour which contributes to the congestion of the editorial process. The various strategies implemented by the editors to oppose congestion are then discussed.

Abstract This study evaluated the effect of intramuscular fat (IMF) content on the quality of pig carcass and meat. One hundred and twenty right half-carcasses of crossbred pigs (Pietrain × Duroc boars and Polish Large White × Polish Landrace sows) from a commercial farm were divided into two groups depending on the content of IMF in the longissimus muscle (LM): LIMF - lower content (mean 2.05% IMF; 28 gilts and 30 barrows) and HIMF - higher content (mean 3.08% IMF; 32 gilts and 30 barrows) were used. Pigs with a higher IMF content in LM (HIMF group) had a significantly lower (P≤0.01) percentage of lean meat in carcass, loin muscle area, level of polyunsaturated fatty acids (PUFAs) and PUFAs/SFAs ratio, whereas backfat thickness, content of cholesterol in LM, levels of saturated fatty acids (SFAs) and monounsaturated fatty acids (MUFAs) were significantly greater (P≤0.01) than those in pigs with lower IMF content (LIMF group).
