The aim of this work was to determine the influence of feeding sheep with frozen fodder on the profile of rumen fermentation and its reflection in blood acid-base equilibrium.
The aim of the study was to estimate the usefulness of measuring the thyroglobulin antibodies (TgAbₛ) concentration in dogs' serum in order to assess thyroid functioning. The study was performed on 383 dogs. The animals were divided into two groups: group A (n = 308) consisted of dogs with hypothyroidism and group B (n = 75) consisted of dogs with euthyreosis. TgAbₛ was determined in both groups. The reaction to the TgAbₛ in group A was strongly positive in 32% of dogs, weakly positive in 33% of dogs, and negative in 35% of dogs. The TgAbₛ were observed in 32% of the dogs from group B, in which 8% of the animals had strongly positive reaction (++) and 24% - slightly positive (+). The correlation between the concentration of total and free fraction of the thyroxin and the level of the TgAbₛ were observed in group A. The tendency to positive reaction to the antibodies (++) in dogs with lower concentrations of total thyroxine and free thyroxine was observed. It was noted that the presence of the TgAbₛ was common in dogs with hypothyroidism. However, it could be also found in the animals with euthyreosis.
Atopic dermatitis is one of the most frequent allergic diseases in dogs. There are many methods of treating its symptoms but specific immunotherapy has recently gained high popularity. Before the application of specific immunotherapy, it is necessary to identify the allergens provoking the reaction of hypersensitivity in the selected animal. This raises a question about the method of allergen identification the medical practitioner decides to use in order to obtain the most credible result. The authors of the present study decided to compare the results of intradermal allergic tests and the results of an IgE screening test carried out using the FceRIa receptor method. The aim of the study was to compare the results of both tests directed to dust and storage mites. The study proves that in case of the IgE screening tests (for a group of allergens), the sensitivity is quite high (85 to 90.69%) but the specificity of these tests is insufficient (25 to 50%). In case of antibodies for the selected mites the sensitivity and specificity was too low (65.1 to 89.4% for the sensitivity, with only 14.2 to 33.3% for the specificity). Only in case of D. petronyssinus the results were higher with the sensitivity calculated at 65.1% and the specificity at 80%. The IgE screening test carried out using the FceRIa receptor method is reliable only in case of screening test for mites and the intradermal allergic test remains the gold standard for allergy testing.
