Hylomyscus denniae endorobae is a rodent important in ecosystems as predator, prey, seed
disperser, determinant of forest tree growth and structure as well as a contributor to
biodiversity which subsequently plays a role in natural livelihood and national
development. Fragmentation of tropical rain forest continues to pose a serious threat to
species diversity, which leads to decreased natural income, primary production and general
breakdown of an ecosystem. This in turn influences food resources and energy available to
animals such as H. d. endorobae. With habitat destruction, H. d. endorobae will get to
human habitat, destroy stored seed crops and transmit diseases. Evaluating gut morphology
changes in response to different diets gives an insight into how animals can survive with
changes in the natural habitat. The study was done to evaluate how H. d. endorobae adapts
to different diets in the face of food scarcity in order to make informed decisions on
conservation of the species. The purpose of this study was to analyze utilization of food
resources by H. d. endorobae. Thirty male rodents (H. d. endorobae) weighing between
35-50g were trapped from Ihururu forest in Nyeri, Kenya, one of the natural habitats of the
rodent species experiencing a lot of anthropogenic activities. Microscopic examinations of
faeces collected from the trapped animals were done to establish the diet of the animal
species in its natural habitat. The individuals were dissected and morphological
measurements taken to establish gut size. Slides of different gut sections were
microscopically examined to establish the number and length of villi. Nine other adult
male rodents were randomly grouped into threes, caged individually and fed on 80g of
different diets for six months to determine the influence of diet on gut morphology,
digestibility and absorption efficiency. Results showed that H. d. endorobae consumes
70.7% seed, 22.6% plant leaf and 6.8% animal matter. There was no correlation between
the mean body weight (40.1 ± 3.9g) and the mean total gut length (62.6 ±1.3cm) of field
collected animals. The mean gut lengths were 62.6 ± 1.3cm, 58.5 ± 4.5cm, 55.7 ± 1cm, and
57.1 ± 2.3cm for field collected animals, wheat, kale and omnivore diets, respectively.
Also, gut length did not show any significant differences (p = 0.889) between H. d.
endorobae fed on different diets. Regression analysis showed no significant difference
between diet and stomach volume (P = 0.205). There was significant correlation (p < 0.05)
between diet and number of villi in the duodenum and caecum of field collected animals
and those fed on wheat and large intestine and caecum of those fed on kale. Also, there
was significant correlation (p < 0.05) between diet and length of villi in all regions of the
gut except in the caecum (P = 0.232) of animals fed on omnivore diet. Diet influenced
digestive efficiency (p = 0.007) with kale diet having the lowest efficiency (77.69%)
compared to wheat diet (95.12%) or omnivore (94.29%). These results suggest that H. d.
endorobae meets its energy demands with minimal gastrointestinal changes and probably
increased food intake. It is recommended that the natural habitats of H. d. endorobae
should be maintained and conserved to prevent its migration to human habitats and
probable species erosion.
