Effect of dietary supplementation with preparation comprising the blend of essential oil from Origanumvulgare (lamiaceae) and Citrus spp. (citraceae) on coccidia invasion and lamb growth,

The aim of the study was to investigate the state of parasitic invasions in flocks of carrier and fancy pigeons in south-western Poland. Coproscopic methods (flotation with saturated NaCl and saccharose, as well as the McMaster method) were used to examine 42 pigeon flocks (18 flocks of fancy pigeons and 24 flocks of carrier pigeons). A total of 210 faeces samples were tested. Prevalence was determined, and average intensity and abundance of gastrointestinal parasites were estimated on the basis of OPG/EPG. Dispersive forms of parasites were found in 78.6% flocks (88.8% of fancy pigeons and 70.8% of carrier pigeons). In the flocks of fancy pigeons most invasions were of mixed character, with statistically significantly high indices of prevalence and abundance. In carrier pigeon flocks, monoinvasions with significantly higher indices of average intensity prevailed, which indicates a high risk of invasion in this group of birds. Eimeriosis was found to be the dominating invasion, occurring in 59.5% of all samples, carrier pigeons – 45.4%, fancy pigeons – 77.7% (59.5% of the flocks), average OPG – 12280, abundance – 7309. Capillariasis: in total – 49% samples, carrier pigeons – 35.8%, fancy pigeons – 66.6% (52.4% of the flocks), average EPG – 3216, abundance – 1577. Ascariasis: in total – 24.3% samples, carrier pigeons – 12.5%, fancy pigeons – 40% (28.6% of the flocks), average EPG – 1953, abundance – 474. Eggs of nematodes belonging to Ornithostrongylus were found in 4.2% of the samples in total: carrier pigeons – 3.3%, fancy pigeons – 5.5% (4.8% of the flocks), average EPG – 488, abundance – 20. Tapeworm eggs were found in 6.2% samples in total, carrier pigeons – 2.5%, fancy pigeons – 11.1% (9.5% of the flocks), average EPG – 607, abundance – 37. The correlation analysis showed relationships between the prevalence and diarrhoea only in the case of tapeworm invasion, no relationship between diarrhoea and the mere fact of infection were found in other invasions. However, a significant correlation was found between the average OPG/EPG of diagnosed parasites (especially Eimeria, Capillaria and Ascaridia) and the observed diarrhoea symptoms.

Established taxa within the Enterobacteriaceae wereisolated from cloacal swabs of Strix aluco chicks in nest boxes located at five research sites. ChromID ESBL medium (bioMerieux) was used to select a pool of Enterobacteriaceae strains producing extendedspectrum beta-lactamases. Drug sensitivity of the chosen strains was determined from the full pool of Enterobacteriaceae to 6 chemotherapeutics of different mechanisms of action. The study evaluated the sensitivity of ESBL-synthesizing isolates to substances belonging to penicillins, cephalosporins, cephamycins, clavams, carbapenems and monobactams. Analysis of the results indicated a potential role of Strix aluco in the dissemination of epidemiologically-relevant Enterobacteriaceae, and, importantly, pose health risks to forest service workers, nature protection service and ornithologists. The results can also serve as the basis for further environmental studies.

the objective of the present research was to assess the instrumental and sensory textural attributes of lamb meat depending on the cold storage ageing under vacuum. the research material included two skeletal muscles, i.e. semimembranosus (sm) and rectus femoris (rf) from carcasses of uhruska lambs. The age of animals ranged from 120 to 135 days. The ageing and muscle influenced significantly shear force and shear energy. However, significantly lower shear force and higher score of tenderness were observed on 7 vs. 2 days of ageing only for sm. the evaluated factors (ageing and muscle) affected slightly and not significantly the parameters of texture profile analysis. The muscle samples after the 7-day ageing showed higher hardness and chewiness. Significant correlation of sensory tenderness with instrumental shear and energy force and springiness was confirmed. The obtained results indicated that vacuum-packed lamb meat during cold storage for 7 days following slaughter develops the sensory attributes, especially tenderness.

Inwazje pasożytnicze zwierząt wolno żyjących charakteryzują się specyficznymi uwarunkowaniami inwazjologicznymi. Wynikają one z naturalnych zależności występujących w określonej biocenozie. Stały kontakt zwierząt ze środowiskiem naturalnym, będącym rezerwuarem form inwazyjnych wielu pasożytów powoduje, że u żywicieli wolno żyjących często obserwuje się znacznie bogatszą faunę pasożytniczą niż u ich udomowionych krewnych. W przypadku braku ingerencji człowieka najważniejszym czynnikiem warunkującym występowanie i przebieg parazytoz tej grupy zwierząt staje się zależność środowiskowa. Z tego względu inwazje cechują się najczęściej wyjątkową różnorodnością i endemiczną specyficznością. Nie bez znaczenia są również pewne uwarunkowania lokalne. W kontekście Lubelszczyzny jest to niewielka liczebność zasobów leśnych okolic Lublina oraz brak bezpośredniej komunikacji z dużymi obszarami leśny-mi pozostałych części kraju. Czynniki te powodują, że wędrówki zwierząt są ograniczone, co wpływa na zachowawczy charakter wielu inwazji.

Internal parasites in roe deer of the Lubartów Forest Division in postmortem studiesSummary The aim of the study was to analyze endoparasitic fauna in roe deer of a selected area of south-western Poland using coproscopic studies and postmortem studies of internal organs (lungs, livers and digestive tracts). Microscopic methods included flotation and the McMaster method. In May and June 2015, 53 culled male roe deer were examined. Parasites were found in 96.2% (n = 51, SD = 19.2) of the studied animals, but the invasion intensity was diversified. From 1 to 7 different taxa (families or genera) of parasites were found in each studied animal. Oocysts of Eimeria (3 species (E. capreoli, E. panda, E. rotunda) were found with the following invasion prevalence: 45.28%, low OPG level, in the range of 350-700. In three samples, the OPG amounted to 2800--4500. Cysts of Buxtonella sulcata 9.4% (CPG in the range of 300-100). Fasciola hepatica (prevalence 3.77%), intensity: 2-3 specimens, Dicrocoelium dendriticum (5.66%), intensity: 2-5 specimens. Moniezia expansa (7.54%), intensity: 3-8 tapeworms. Nematodes from the family Trichostrongylidae (58.49%, genera: Ostertagia, Spiculopteragia, Haemonchus, Trichostrongylus and Nematodiurus from the family Molineidae), low invasion intensity (8-55 nematodes), only in 7 deer intensities of 346-140 nematodes). Capillaria bovis (7.54%) intensity ranging from 2 to 14 nematodes. Oesophagostomum venulosum (15.09%) invasion intensity: 7-23 nematodes, Trichuris globulosa (9.43%), invasion intensity 2-4 nematodes. Dictyocaulus eckerti (11.32%), invasion intensity ranging from 6 to 34 nematodes. Setaria tundra (5.66%) invasion intensity ranging from 1 to 3 nematodes.
