Performance of calves submitted to protocols using extruded or ground starter
Brazilian Archives of Biology and Technology, 2014 Feed processing can affect rumen development in new born calves, and potentially define animal performance. Two feed management systems, extruded starter (Ruter) with possible early weaning and ground starter (control), were evaluated in thirty-two ...

Limnology and Oceanography: Methods, Volume 24, Issue 2, February 2026.Abstract Imaging Pulse Amplitude Modulation (PAM) fluorometry allows spatially resolved measurements of Photosystem II (PSII) fluorescence kinetics through time without disturbing study organisms or their environments. In particular, the use of photosynthesis–irradiance curves (P–I curves) provides detailed information on PSII quantum efficiency ...

Exploring the Spatial-Temporal Microbiota of Compound Stomachs in a Pre-weaned Goat Model
Frontiers in Microbiology, 2018 Ruminant animals possess a characteristic four-compartment stomach (rumen, reticulum, omasum, and abomasum) that is specialized for pre-intestinal digestion of plant materials. Of these four compartments, the rumen is the largest.

A Method of collecting Fluid leaving the Omasum of Sheep [PDF]
Nature, 1954 IN ruminants a large proportion of the ingested food is digested in the fore-stomachs. In order to know the final result of this digestion, it is necessary to know the composition of the material leaving the fore-stomachs and the rate of flow at the omaso-abomasal orifice. To study this problem a special cannula has been devised (Fig. 1).

Left‐displaced abomasum in a late‐pregnant goat
Veterinary Record Case Reports, Volume 14, Issue 1, February 2026.Abstract A female goat in late gestation was presented to a veterinary teaching hospital due to the sudden onset of abdominal distention and signs of cardiovascular depression. On admission, the goat exhibited an overloaded rumen, which seemed noticeably distant from the abdominal wall on the left‐hand side.

Gross Anatomy of the Blue Wildebeest Stomach (Connochaetes taurinus Burchell, 1823) [PDF]
Mongolian Journal of Biological Sciences, 2019 Wildebeests, also called gnus, are antelopes belonging to the genus Connochaetes of the family Bovidae. The macroscopic anatomy of the stomach of an adult blue wildebeest (Connochaetes taurinus), was studied.

Journal of Animal Physiology and Animal Nutrition, Volume 110, Issue 1, Page 148-168, January 2026.ABSTRACT Evolution has enabled ruminants to develop a complex rumen microbiota that aids in the digestion of fibrous feeds. This study examines whether promoting a highly diverse rumen microbiota during early life continues to offer long‐term benefits in modern dairy production systems, where young ruminants are reared without exposure to adult ...

iMeta, Volume 4, Issue 6, December 2025.Single‐cell and transcriptomics from 1.79 million cells identify the forestomach epithelium as the dominant site of antioxidant activity and oxidative phosphorylation (OXPHOS) in the bovine gastrointestinal tract. Along the basal‐to‐luminal differentiation axis, antioxidant capacity and OXPHOS rise in a coordinated metabolic–redox gradient.

Food or family? How gut microbes respond to diet and phylogeny in two deer species
Ecosphere, Volume 16, Issue 10, October 2025.Abstract Vertebrate herbivores require symbiotic gastrointestinal (GI) microbes to extract energy and nutrients from fibrous and sometimes toxic plant diets. Because GI microbes vary in their relative abundance, function, and degree of specialization, the microbial community depends on both the characteristics of plants consumed and the anatomical ...
