Following previous studies on Croatian veterinary students? attitudes and opinions towards farm animal and pet welfare, the present study assessed their attitudes towards sheep and goat welfare, focusing on the year of veterinary medicine study and area of student residence. The questionnaire survey involved students of all six years of the integrated undergraduate and graduate study programme at the Faculty of Veterinary Medicine, University of Zagreb, Zagreb, Croatia. First-year students filled out the questionnaire twice, before and after having attended the animal welfare subject. The questionnaire consisted of two sections. The first section included questions on student demographic and experiential characteristics, whereas the second section asked them to define the level of cognition, sentience and welfare compromise in sheep and goats through five-point Likert scale questions. Study res...

The study included four groups of heifers observed during four-month final commercial fattening. The heifers were housed in non-enriched and enriched environments at low (n = 14; 4.5 m2/animal) and high (n = 19; 3.3 m2/animal) stocking density. Environmental enrichment consisted of a grooming brush and salt blocks. Heifer welfare was assessed using selected indicators from the Welfare Quality® assessment protocol for cattle. The study results showed that the heifers housed at high stocking density used environmental enrichment materials significantly more frequently as compared with heifers housed at low stocking density (P<0.05), whereas there was no difference in their use of particular enrichment materials. The effect of environmental enrichment on heifer welfare was mainly manifested in a reduction in the expression of some forms of aggressive behaviour; therefor...

Levels of airborne bacteria established in the air of the poultry house ranged from 1.02×10 4 CFU/m3 measured in April, to 7.72×10 4 CFU/m3 measured in December. Mean values of the total number of fungi ranged from 0.075×10 4 CFU/m3 measured in September, to 8.56×10 4 CFU/m3 measured in June. Established values of air temperature, relative humidity and air velocity were, generally, in accordance with the technology-predicted ranges. The determined number of bacteria and fungi in the air, as well as the statistically significant impact of microclimate conditions on their number in the air of the cage housed laying hens facility, are in accordance with considerations for standards set for air quality in livestock buildings and the development of reliable systems for monitoring the above factors. The aim is to create production that, besides the econom...

The composition may depend on animal species, building construction, animal accommodation, and microclimate parameters, to name just a few factors. Pathogens contained may be a serious threat to animal and human health. The aim of our study was to analyse the fungi aerosol content in a stable housing dairy cows and in a coop for laying hens over the three autumn months of 2007. The air was sampled on Petri dishes with Sabouraud glucose agar. After laboratory treatment, we identifi ed the most common fungi. Their count in the stable ranged from 3.98x103 CFU m-3 to 5.11x104 CFU m-3 and in the coop from 6.89 x104 CFU m-3 to 1.13x105 CFU m-3. The difference between the two animal dwellings was statistically different at the level of p<0.05. In both dwellings, the most common were the fungi Aspergillus sp., Penicillium sp., and yeasts, followed by Cladosporium sp., Fu...

Stoga se u praksi primjenjuju higijenski standardi koji tijekom proizvodnog ciklusa osiguravaju optimalne životne uvjete, a ujedno sprjecavaju unosenje i sirenje uzrocnika bolesti. Oni obuhvacaju preventivne mjere, higijensko sanitarne postupke, stvaranje mikroklimatskih ambijentalnih uvjeta prikladnih kategoriji životinja, nadzor zdravstvenog stanja i kontrolu kretanja. U provedenom istraživanju mjereni su pokazatelji mikroklime, uzorkovan je zrak s ciljem utvrđivanja broja mikroorganizama, uzimani su brisovi s izloženih povrsina.

Tako je osmišljen koncept planiranja i upravljanja zdravljem stada, uključujući mliječne krave, čijim se preventivnim mjerama nastoje očuvati zdravlje i dobrobit životinja te dobra proizvodnost. Stoga higijena držanja životinja ima krucijalnu ulogu u konceptu zdravlja stada, uključujući smještaj i mikroklimatske uvjete, njegu životinja, higijenu hrane i vode te biosigurnost na farmama. Suradnja između doktora veterinarske medicine i stočara od iznimne je važnosti.

The aim of this study was to measure the mass fraction of Asp f 1, a major allergen ofAsperillus fumigatusin 37 indoor dust samples collected from four poultry farms in a rural area of the Zagreb County (Croatia) using the enzyme-linked immunosorbent assay. More than 62 % of dust samples had detectable Asp f 1 levels (limit of detection 3.6 ng g-1). The overall mean Asp f 1 level was 17.9 ng g-1[range (3.8 to 72.4) ng g-1]. Satisfactory results were obtained for analytical within-run imprecision (6.7 %), between-run imprecision (10.5 %), and accuracy (91 % to 115 %). Microclimate parameters (air temperature, relative humidity, and velocity) were within the recommended ra...
