Intraspecific Scaling of Rumen-reticulum Fill Might Depend on Dietary Fiber

The American Midland Naturalist, 2014
Body mass - gut fill scaling relationships affect rate of digestion, foraging behavior, niche differentiation, and trophic interactions. On an intraspecific level, the scalar of this relationship has been reported to be both iso- and allometric (,1.0). We hypothesized the scalar of rumen-reticulum fill depends on diet.

Partition of capillary blood flow in rumen, reticulum, and omasum of sheep.

American Journal of Physiology-Endocrinology and Metabolism, 1977
Using radioactive microspheres, mucosal and muscular capillary blood flow have been measured in the rumen, reticulum, and omasum of conscious sheep. Total forestomach capillary blood flow (7.7 ml min(-1) kg body wt(-1)) was about 7% of cardiac output; 95% of the flow was in the mucosa and only 5% in muscle layers.

Does rumen–reticulum capacity correlate with body size or age in black-tailed deer?

European Journal of Wildlife Research, 2011
To accommodate an increased food intake with greater body size, rumen–reticulum capacity must become larger to allow heavier digesta loads. Recently, digesta load was found to correlate with age more strongly than body size. It was suggested that older animals had compromised mastication efficiency due to tooth wear and compensated for larger particles

Rumen–reticulum characteristics, scaling relationships, and ontogeny in white-tailed deer (Odocoileus virginianus)

Canadian Journal of Zoology, 2012
Scaling relationships between body mass and gut capacity are valuable to predicting digestive efficiency. Interspecific scaling relationships between body mass and gut capacity have consistently estimated a slope of 1.0; however, intraspecific scaling relationships between body mass and gut capacity have been highly variable.
