Hindgut fermentation in ruminating Holstein calves
… of dietary starch and type of dietary protein on hindgut fermentation were evaluated. Thirty-two Holstein bull calves were fed diets containing variable amounts of orchardgrass hay and a grain mixture. The amount of starch and types of protein were: [L1] low starch, soybean meal (SBM); [L2] low …

Multinuclear and Mononuclear Polyploidy in the Drosophila Hindgut and Heart
<p>A fundamental question of biology is how tissues are organized. Tissues can be composed of many small cells or comparatively fewer large cells that add nuclear content to facilitate tissue growth. The cells can be separate, discrete units or interconnected collectives. The nuclear composition of …

Community Composition and Function of the Hindgut Microbiome in Seaweed-Eating Marine Fish
… most to CAZyme-related gene expression in the hindgut, particularly in the biomass-rich hindgut chamber. The enrichment of CAZyme gene clusters (CGCs) within Alistipes underscores its enhanced capacity for utilizing macroalgal polysaccharides including alginate, laminarin and sulfated …

Further elucidating the effects of ruminal and hindgut acidosis on the ruminant animal
… study was to determine the effects of induced hindgut acidosis in sheep on cecal pH, ruminal fermentation, and gut permeability. Eleven ruminally and cecally cannulated ewes (49 ± 4 kg) were assigned to one of two treatments: control (CON; n = 5) or induced hindgut acidosis (HGA; n = 6). To …

Investigating the actinomycete diversity inside the hindgut of an indigenous termite, Microhodotermes viator
… fairly recently, most investigations of termite hindguts involved the higher termites from the Termitidae family. Little attention was paid to the lower termites, and even less to the family Hodotermitidae. The main aim of this project was to explore the actinobacterial diversity of the paunch …

Trends in Equine Nutrition and the Effects of a Hindgut Buffer Product in Overconditioned Horses
… and lastly, determining the effects of a hindgut buffer in overconditioned horses following an abruptly introduced moderate nonstructural carbohydrate (NSC) meal. There were no differences in nutritional management between hunter and jumper disciplines and most representatives (n=89) had …

Characterizing the microbiota and profiling small non-coding RNAs in the compartments of the equine hindgut
… structures residing within compartment of the hindgut and to begin to profile gene expression patterns of small RNAs within the same areas. Two different populations of animal subjects were used for the two projects in this thesis: a herd from the University of Kentucky (n=6) and a herd from …

Molecular characterisation of the fibre-digesting bacteria isolated from the ostrich (Struthio Camelus var. Domesticus) hindgut
… strains that have been isolated from the ostrich hindgut, have successfully been identified with the aid of PCR amplification of the 16S rDNA genes and sequence analysis using the BLASTN search of the GenBank database. The nucleotide sequences were determined either through direct sequencing of …

Hindgut secretions in <I> Camponotus pennsylvanicus </I> (De Geer) (Hymenoptera: Formicidae): attractants and nitrogenous excretory materials
… by presenting workers with crude or synthetic hindgut extracts to test for attractancy and trail-following behavior. Chemical analysis was used in conjunction with behavioral bioassays to detect and identify volatiles from the rectal sac, poison, and Dufour's glands. The rectal material was …

Digesta Passage, Fermentation, and Microbes in the Hindgut and Its Relative Contribution to the Nutrition of Cattle
Fermentation in the cecum and colon and digesta passage through the intestines were investigated in a series of experiments. Specific gravity, but not length, of inert particles affected their passage through the intestines. Passage was quickest for particles with a specific gravity of 1.17 and …

Digestibility of Two Complete Pelleted Diets by the Horse (Equus caballus) as a Model Animal for Nondomestic Hindgut Fermenters
… animal models are often referenced. Herbivorous hindgut fermenters, such as horses, zebra, and rhinoceros, rely on microbial fermentation in the cecum and colon to utilize dietary structural carbohydrates. The study objective was to measure the digestible energy of two (LOW, HIGH) complete …

Gut-associated microbial symbionts of the marsh fiddler crab, Uca pugnax
… protists were documented in the host stomach and hindgut. For these sections, we have described morphologies, measured abundances and characterized the genetic diversity (bacteria) of resident microbes. Presence and abundance of the Eccrinales protists depends on host molt stage as all eccrinid …

Gut-associated microbial symbionts of the marsh fiddler crab, Uca pugnax
… phylotypes. An exception was the U. pugnax hindgut phylotype most closely related to a phylotype identified from hindguts of the detritivorous shrimp Neotrypaea califomiensis. This finding suggests that detritivorous crustacean hindguts may provide an ecological niche for specific bacterial …

Influence of feed efficiency ranking and maternal nutrition on gut microbiome, metabolome, and transcriptome in beef and dairy cattle
… experiment was to determine differences in hindgut microbiome and metabolome in neonatal dairy heifer calves retrospectively grouped as M-eff or L-eff calves during the preweaning period. Rectal swabs were collected immediately at birth before colostrum feeding (i.e., d 0), and fecal samples …

Mechanisms Underlying Variation in Insect Chill Tolerance: The Role of Ion and Water Transport
… function modifications by comparing the hindgut and Malpighian tubule transcriptomes of warm- and cold-acclimated individuals. Cold acclimation modified the expression of hindgut and Malpighian tubule ion transporters, and hindgut structural (cytoskeletal and cell junction) genes. Rectal …

The Influence of Prebiotics, Probiotics, and Exposure to an Opportunistic Pathogen on the Intestinal Microbiome of White Shrimp (Litopenaeus vannamei)
… Vibrio parahaemolyticus ( VP-EMS) on the mid and hindgut microbiome of Pacific white shrimp (Litopenaeus vannamei). A monoculture probiotic strain of Bacillus subtilis spores: O14VRQ, and a prebiotic product of cultured Saccharomyces cerevisiae cell walls: MOS, were administered to shrimp as feed …

A pharmacological study of signal transduction mechanisms controlling fluid reabsorption and Ion transport in the locust rectum
… and consists of the Malpighian tubules and the hindgut. The Malpighian tubules secrete a primary isosmotic urine rich in KC1 and low in Na+ that contains most small hemolymph solutes, waste products and toxic plant chemicals. The hindgut (ileum and rectum) is responsible for the enormous changes …

The Gut Microbiome and its Relationship to Migratory Behaviour and Fate in Wild Fishes
… was to investigate the hypothesis that the hindgut microbial communities vary relative to migratory behaviour and fate in wild fishes. Specifically, I assessed hindgut microbial communities in three fish species that exhibit different migratory behaviours using 16S rRNA gene amplicon …
