Description
Summary:The intensity of urea recycling in the wild herbivorous European hare has been investigated. The intensity of urease activity in the gastrointestinal tract has been selected as a convenient quantitative measure of nitrogen recycling. High urease activity was detected in the large intestine; it was higher than the previously detected activity in other mammals with postgastric fermentation: pigs, rats, and rabbits. The strong seasonal dynamics of urease activity has been noted: it increases during winter diet consumption, which is poor in available nitrogen.
