[Response of glutamic oxaloacetic transaminase, lactate dehydrogenase and aldolase in serum of cattle after transportation stress].
The response to transport stress of serum GOT, LDH, and ALD was studied in 35 heads of cattle, aged 18 months to 20 years. The influence of different factors upon serum enzyme behaviour in cattle after exposure to transport stress was tested by means of mathematico-statistical methods. The following conclusions were drawn: 1. Transport stress on cattle was followed by rise in GOT, LDH, and ALD activities in serum. 2. The strongest rise was recorded from ALD activity and the smallest from LDH. 3. All three serum enzymes continued to rise up to the time of slaughter (20 to 50 hours after transport). 4. The enzyme activities recorded from blood after slaughter did not differ significantly from those in venous blood. 5. Intensity of ALD activity rise was found to depend on the transport distance (if it was more than 20 km), age of animal, and ambient temperature. 6. The rise in GOT activity was found to depend only on the given ambient temperature. 7. The behaviour of LDH activity did not reveal any secured relationship with any of the examined factors (transport distance, age keeping, and tuberculosis state or ambient temperature).
