The effect of aging on laboratory values in dogs.

The main objective of this study was to examine age-associated changes in laboratory values in dogs in order to establish standard values for dogs of a certain age. These standard values could serve to judge the health status of individual dogs and possibly estimate their remaining life expectancy. Thus, haematological and immunological parameters, plasma constituents, kidney characteristics and the capacity of homeostasis were determined in German shephard dogs (0.

Simultaneous treatment of chickens with salinomycin and tiamulin in feed.

Laboratory and field experiments involving more than 100,000 birds were performed to assess the effect of simultaneous in-feed medication of chickens with salinomycin and tiamulin at various concentrations. In an artificial infection study with Mycoplasma gallisepticum, low levels of tiamulin (10-40 ppm) did not induce signs of ionophore intoxication with salinomycin at 60 ppm in the feed, whereas levels of 50 ppm caused early signs with a mild growth depression. A level of 20 ppm gave a maximum average improvement in growth rate of 12.

Bronchoalveolar lavage in dogs; analysis of proteins and respiratory cells.

In an attempt to establish the normal values, bronchial alveolar lavage (BAL) of portions of the right upper lobe was done during fiberoptic bronchoscopy in 18 Beagle dogs of various ages. Albumin, IgA and IgG were identified in BAL fluids. The respiratory cells obtained were, in the order of decreasing occurrences, alveolar macrophages, lymphocytes, epithelial cells and neutrophils.

Epizootiological examination of a respiratory disease associated with mycoplasma infection in horse.

The authors examined 585 samples from 92 mares of 2 studs and 346 nasal swabs taken from their foals for the presence of mycoplasmas. The positive rates of mares and foals were 81.5% and 71.
