Immunodetection of Cocaine‐ and Amphetamine‐Regulated Transcript in the Rumen, Reticulum, Omasum and Abomasum of the Sheep

Anatomia, Histologia, Embryologia, 2009
SummaryEnteric nerves harbour a wide array of neuropeptides playing a key role in the regulation of gastrointestinal tract functions. In this study, the distribution patterns of cocaine‐ and amphetamine‐regulated transcript‐immunoreactive (CART‐IR) nerve fibres as well as the percentages of CART‐positive enteric neurons were immunohistochemically ...

Rumen–reticulum organ mass and rumen mucosa surface area of white-tailed deer (Odocoileus virginianus) consuming two energy diets

Canadian Journal of Zoology, 2020
Flexibility in gut morphology has fitness consequences in herbivores. To accommodate dietary variation in energy concentration, rumen–reticulum absorptive capacity and organ mass might also covary. We hypothesized that low energy diets result in greater food intake but lower volatile fatty acid concentrations.

Daytime declines in rumen–reticulum fill of male white-tailed deer (Odocoileus virginianus) from south Texas

Canadian Journal of Zoology, 2014
Understanding rumen–reticulum fill dynamics gives us insight into how environmental conditions influence animal behaviors that affect when animals access forage. We examined whether there were daytime declines in rumen–reticulum fill in response to high ambient temperatures in free-ranging white-tailed deer (Odocoileus virginianus (Zimmermann, 1780 ...

Variation Across Years in Rumen-Reticulum Capacity and Digesta Load in White-Tailed Deer (Odocoileus virginianus)

Southeastern Naturalist, 2013
How gut capacity and digesta loads vary with unpredictable forage quality and abundance has not been examined in ruminants. Odocoileus virginianus (White-tailed Deer) should have greater rumen-reticulum capacity during drought years to accom- modate heavier digesta loads due to diets that contain a greater fraction of indigestible material. In contrast,

Allometric scaling of rumen–reticulum capacity in white‐tailed deer

Journal of Zoology, 2009
Scaling of gut capacity with body weight is part of a hypothesis explaining digestive efficiency across the spectrum of body sizes in ruminant species. Larger animals should retain digesta longer because of gut capacity relative to metabolic demands. Interspecific variation in digestive efficiency is an integral part of the Bell–Jarman principle, which

Microbial diversity in the rumen, reticulum, omasum, and abomasum of yak on a rapid fattening regime in an agro-pastoral transition zone

Journal of Microbiology, 2018
The ruminant digestive system harbors a complex gut microbiome, which is poorly understood in the case of the four stomach compartments of yak. High-throughput sequencing and quantitative PCR were used to analyse microbial communities in the rumen, reticulum, omasum, and abomasum of six domesticated yak.

Use of rumen–reticulum fill to examine nutrient transfer and factors influencing food intake in white-tailed deer (Odocoileus virginianus)

Canadian Journal of Zoology, 2015
Estimating relationships of gut fill in mammalian herbivores is useful to understanding digestive functions. Large animals might have more fluid in the gut to facilitate nutrient transfer between the gut lumen and the gut wall. Furthermore, relationships between concentrations of dietary refractory and indigestible fiber (CRIF) and gut fill might ...

Nutritional evaluation of diets. Simulation model of digestion and passage of nutrients through the rumen-reticulum

Animal Feed Science and Technology, 1997
Abstract To evaluate the nutritional behaviour of simple and complex diets provided under different feeding regimes, a stochastic, dynamic and predictive simulation model was developed. Feed fractions, considered in the model were soluble non-structural carbohydrates (SNSC), insoluble non-structural carbohydrates (INSC), INSC degradation rate ( kd ...
