Transcriptomic analysis of the genes for lactate dehydrogenase isomers in the reindeer' rumen of the Nenets Autonomous District in summer
Reindeer are unique arctic ruminants. They exist in conditions of extremely poor nutrition; therefore, the processes occurring in the rumen are of great scientific interest. It is known that the formation of lactate in the rumen is a key mechanism of metabolic disorders in the body of ruminants. The...
