Pig Carcasses

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. .

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).

The Impact

The paper presents the results of research on the environmental impact of sewage ponds serving the city of Kostanay (Kazakhstan). The scope of the research included the determination of basic quality parameters of raw and treated wastewater, an analysis of the chemical composition of groundwater in the vicinity of sewage ponds, and the analysis of the water quality of the Tobol River. The obtained results indicate that sewage from storage ponds, infiltrating into the ground, caused groundwater pollution in the area of about 100 km2 around the reservoirs. Due to the fact that the groundwater aquifer in the vicinity of sewage ponds feeds the Tobol River, it also affects water quality in the river, which does not meet the requirements for most of the analyzed parameters.

The subject of this research was to determine the effect of the housing system on quality of welfare of dairy cattle in Serbia. Study was realized on six farms, capacity of 30 to 900 cows, with loose and tie housing system. Assessment of the welfare quality parameters was done by using the Welfare Quality? Assessment Protocol for Cattle, 2009. Results of the research show that the welfare quality of dairy animals is under the significant effect of housing system, and that loose system has the advantage when it comes to comfort around resting, easy of movements and health condition of cows. Share of not lame cows (81%) and cows with no lesion (86%) was significantly higher (p<0.01) in loose system. Indicator values: duration of lying down movements (6.53 sec), lying down movements with collisions (18.7%) and lying outside lying area (28.4%) in tie system were significantly higher (p<0.01) compared to loose system indicating the inadequacy of the housing and lack of comfort. Analysis of indicators associated with cow hygiene (dirty legs and udder) and diseases (dystocia) points to significant gaps in management in both housing systems which represent significant threat to cow welfare quality.

This paper reports the findings of three water point mapping (WPM) studies carried out in three rural districts of Tanzania covering 3,363 water points. The methodology was designed to estimate the influence that consideration of the quality of the water supplied and the year-round functionality of each water point would have on each district's coverage figures. To this end, the study included measurements of basic quality parameters (692 analyses) and characterisation of the year-round continuity of service, in addition to the data collected in standard WPM campaigns. Both the quality and year-round continuity results were analysed in a disaggregated form by water point technology. The results show that 22% of the improved water points analysed had more than 10 CFU (colony-forming units)/100 ml of water and 19% were seasonal. Moreover, water service coverage in the districts studied fell 40% on average when quality and year-round continuity were considered. There is a strong need to include these basic factors in the minimum standards to be delivered and monitored in rural areas. Simple and efficient methodologies for including quality and year-round continuity measurements in the information routines, such as the one presented here, are a necessary step to this end.

In this paper a comparative research relating to evaluation of the quality of pig carcasses originating from Swedish Landrace was carried out, total of 248 fatteners divided into two groups depending on the back fat thickness on withers and back. Quality was determined by partial dissection of left carcass sides according to procedure recommended by EU. The effect of back fat thickness on withers and back on quality of carcass sides, i.e. its effect on the share of muscle tissue, skin with subcutaneous fat tissue and intermuscular fat tissue in carcass side, was investigated. Obtained data show that exhibited difference in meat yield between groups wasn't statistically significant (P>0,05) in any of the cases. However, by testing the differences in relative yield of skin with subcutaneous fat tissue of leg, share of intermuscular fat tissue of shoulder, LSD and TRS, significance at the level of 5% was determined in fatteners with greater back fat thickness on withers. Observed differences relating to the effect of back fat thickness on share of skin with subcutaneous fat tissue in the carcass were significant and highly significant (*P<0,05 and **P<0,01). Positive correlation of medium strength was established (0,66859) between back fat thickness and content of skin with subcutaneous fat tissue. Between the content of intermuscular fat tissue and back fat thickness a strong positive correlation was established (0,76648).

In this preliminary study, two non-filtered virgin olive oils (one freshly produced VOO-N; one VOO-O stored for one year) were subjected to moisture removal with mineral clay (raw or activated) and analyses were performed to attest possible effects on the quality of the product. The results demonstrated that the treatment of oil with mineral clay at 36-38 °C had no negative effect on the basic quality parameters or on the volatile comound profile. On the other hand, a significant decrease in the water amount as well as in pigments was observed in the samples subjected to this kind of treatment, in particular with raw clay. Regarding the colour measurement, the lightness (L) as well as the consumers’ acceptability exhibited a marked increase when oils were treated with raw clay.

The evaluation of multi-layers lignite deposits is mainly based on borehole data. The lack of sufficient number of analytical data of waste and carbonaceous layers, leads to the use of indicative values during the evaluation and consequently affects the estimation precision of recoverable lignite quality. In the present work the possibility of determination of basic quality parameters of waste and carbonaceous layers by using an expert system was investigated. The development of the expert system was based on the available analytical data of waste and carbonaceous layers and the coded descriptions of corresponding cores. The expert system was used for the estimation of quality characteristics of waste and carbonaceous layers from selected core of Southern Field mine of Ptolemais area. The quality characteristics of the estimated recoverable lignite shows a more intense fluctuation compared with this obtained by using indicative values for waste and carbonaceous layers.

Abstract. The objective of the study was to assess bone breaking strength, keel bone status and egg quality parameters of Lohmann Silver (LS) and Lohmann Tradition (LT) layers housed in small group systems (SG) and furnished cages (FC) in comparison to an aviary system. At the end of the 3rd, 6th, 9th and 11th laying month, approximately 40 hens were randomly chosen from each housing system and slaughtered (478 hens in total). Humerus and tibia strengths were analysed using a three-point-bending machine. Keel bone status was evaluated on a scale from 1 (severe) to 4 (no deformity). Shell breaking strength was measured every four weeks, totalling 4,887 eggs. Statistical analyses were performed using the MIXED procedure of SAS. Humerus and tibia strengths of LS layers housed in SG were significantly higher compared to LS hens kept in FC. Bone breaking strengths of humerus and tibia in LS and LT layers were highest in the aviary system and the differences to the other housing systems were significant. No significant differences in tibia and humerus bone breaking strengths were found between SG and FC for LT hens. Keel bone status was not significantly influenced by housing system or laying strain. For both hybrids, shell breaking strength was significantly lower in SG compared to FC and aviary system. The results showed that SG systems can significantly enhance bone breaking strength for LS layers in comparison to hens kept in FC. The lower shell breaking strength of eggs in SG might slightly impair economic aspects.

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).
