Celem badań było określenie wartości odżywczej mięsa kurcząt brojlerów transportowanych na różne odległości (0,100,200 oraz 300 km). Stwierdzono, że transport nie miał znaczącego wpływu na oceniane składniki. Badane mięso cechowało się wysoką wartością odżywczą i dietetyczną. Świadczy o tym wysoka ilość białka i niska zawartość tłuszczu. Wysoką wartość odżywczą mięsa podkreśla profil kwasów tłuszczowych z dużą ilością kwasów mono- i polienowych, a także niska zawartość cholesterolu.

The aim of this study was to determine the nutritive value of broiler chicken meat transported over various distances (0, 100, 200 and 300 km). It was found that the transport had no significant effect on the assessed components. Meat examined was characterized by high nutritive and dietary value. It was evidenced by the high protein and low fat content. The high meat nutritive value was confirmed by fatty acid profile with a large number of mono- and polyunsaturated ones and the low cholesterol content.

The aim of this study was to assess the relationship between living conditions (microclimate, aerial contaminations, box dimension, access to the paddock/pasture) of horses kept in 3 stables and physiological indicators (protein and its fractions in serum, haptoglobin). The study was carried out for 4 months during autumn and winter in 3 stables. Blood samples were collected from 10 clinically healthy adult horses from each stable (30 in total) in 4 terms – every 4 weeks. Environmental conditions were evaluated according to zoohygiene methodology and current law regulation. In the blood serum, the analyzed parameters were: total protein (g/L) – with the biuret test, the contribution of individual serum protein fractions (%) (albumin and α1-, α2-, β- and γ-globulin) – set to serum protein electrophoresis on agarose gels in an SAS-MX electrophoresis chamber; haptoglobin concentration (g/L) – immunoturbidimetric test. Living conditions meeting the requirements of welfare were provided in stable 3 in terms of both microclimatic parameters as well as the dimensions of the boxes and access to paddock and pasture. Slightly worse conditions were recorded in stable 2, while stable 1 was characterized by not only the worst microclimatic parameters, but also the surface of the boxes was too small. The different living conditions of horses in different stables were reflected in the diverse values of the blood indicators. Although the obtained ratios of protein indicators corresponded to the values of normal adult healthy horses, it was demonstrated that in the serum of horses in stables 1 and 2, as compared to the stable 3, a significantly lower fraction of albumin and higher α2-globulin and a higher concentration of Hp was found – suggesting the effect of different living conditions on organism homeostasis indicators. It may be stated that living conditions significantly influence the physiological condition of the horse.

The aim of this study was to determine the effect of different variants of pre-slaughter procedures in the winter on body weight loss in broiler chickens, and on the proximate chemical composition and physicochemical properties of meat. At the completion of a six-week rearing period, 240 ROSS 308 chickens were subjected to the following variants of pre-slaughter transport: no transport (N-T), transport to a distance of 100 km (T-100), 200 km (T-200) and 300 km (T-300). The acidity of breast muscles (pH₁₅ and pH₂₄) was measured with a portable meat pH-meter, HI 99163 (Hanna Instruments, Germany) supplied with an FC 232D electrode. Meat color (15 minutes and 24 hours post mortem) was determined with the use of a Minolta CR-400 chroma meter (Japan), in the CIE L* a* b* system. Water-holding capacity (24 hours post mortem) was determined as drip loss. The content of water, protein and fat in meat was determined using an InfraLab 710 near-infrared analyzer (NDC Infrared Engineering, UK). The results of the conducted study showed that the elongation of transport length for a distance of 200 km and 300 km influenced the increase of broiler weight loss. Significantly higher (P = 0.01) weight loss was observed after transport to a distance of 200 and 300 km, compared to a group of chickens from group T-100 (respectively 2.65%, 2.36% and 1.41%). It cannot be stated clearly that variants of transportation have contributed to the deterioration of the quality of the meat acquired. The longest transport distance resulted in a faster rate of the pectoral muscle glycolysis in group T-300 (0.69 units) compared to the other groups (0.60-0.62 units). The broiler meat from group T-300, as compared to the other groups, was also characterized by a significantly higher surface of drip loss and the parameters L * 24 and b * 24, which reflected in its significantly lighter color and lower water-holding capacity. However, the final pH values were similar in all groups and did not show any meat defects. In addition, the basic chemical composition of chicken muscles showed their good nutritional value.
