Effects of commercial aldehydes from green leaf volatiles (green odour) on rumen microbial population and fermentation profile in an artificial rumen (Rusitec).

The effects of plant metabolites on rumen metabolism vary greatly depending on their antimicrobial spectrum and applied doses. In this study, the minimum inhibitory concentrations (MICs) of commercial aldehydes, trans-2-hexenal (T2H), cis-3-hexenal (C3H), trans-2-nonenal (T2N), and trans-2-decenal (T2D) from green leaf volatiles, were tested on rumen bacteria. These compounds were found more effective on Gram-positive rumen bacteria than the Gram-negatives, and C3H was the most effective compound.

Frequency of dog erythrocyte antigen 1.1 in 4 breeds native to different areas in Turkey.

Background: Dog erythrocyte antigen (DEA) 1.1 is the most important RBC antigen clinically, as it is highly immunogenic and causes acute hemolytic transfusion reactions (HTR) in sensitized dogs.

Objectives: The aims of this study were to determine the frequency of DEA 1.
