Hindgut is a major colonization site for Escherichia coli O157 in cattle. In this study, diets were formulated to effect changes in hindgut fermentation to test our hypothesis that changes in the hindgut ecosystem could have an impact on fecal shedding of E. coli O157. Feedlot heifers (n = 347) were prescreened for the prevalence of E. coli O157 by fecal and rectoanal mucosal swab cultures. A s...
Crude protein requirements of finishing cattle over 1000 lb are below 10 percent of dietary dry matter (NRC, 1976). However, crude protein is usually fed in excess of 10 percent of DM due to decreased feed intake and performance at lower protein levels. Finishing diets usually consist of cereal grains fed ad libitum. With milo and corn grains, substantial quantities of starch are not completely...
Available energy from hindgut fermentation to pigs fed various amounts of dietary fiber was investigated using an in vivo-in vitro methodology. Six growing pigs fitted with a simple T-shaped cannula at the terminal ileum, and following a Latin-square design, were fed 3 diets differing in the content of non-starch polysaccharides (NSP): a low fiber diet (LFD, 77 g/kg of DM), a standard fiber die...
BACKGROUND Dietary fibre-induced satiety offers a physiological approach to body weight regulation, yet there is lack of scientific evidence. This experiment quantified food intake, body weight and body composition responses to three different soluble fermentable dietary fibres in an animal model and explored underlying mechanisms of satiety signalling and hindgut fermentation. METHODS Young ...
Indigestible sugars (iS) have received particular interest in food and nutrition research due to their prebiotic properties and other health benefits in humans and animals. The main aim of this review article is to summarize the current knowledge regarding digestive and health-enhancing properties of iS such as sugar alcohols, oligosacharides, and polysaccharides, in rodents and rabbits. Beside...
Hyperlactate production is related to disorders of the large intestine such as inflammatory bowel diseases. Lactate, an intermediate in hindgut fermentation, is metabolized to SCFA. Megasphaera elsdenii can convert lactate to butyrate, a physiologically important organic acid for the hindgut mucosa. This experiment was conducted to determine whether M. elsdenii normalizes hyperlactate productio...
Next to rumen acidosis, other forms of acidosis may also affect lactational performance cows. Therefore, the effects hindgut induced via abomasal infusion ground corn, and metabolic NH4Cl, were studied in cows early lactation. Observations made on intake digestibility nutrients, lactation performance, energy N partitioning, blood acid-base status, fermentation characteristics. In a 6 × Latin sq...
Canola co-products are sources of amino acid and energy in pig feeds, but their fermentation characteristics in the pig intestine are unknown. Thus, we determined the in vitro fermentation characteristics of the canola co-products Brassica juncea solvent-extracted canola meal (JSECM), Brassica napus solvent-extracted canola meal (NSECM), B. napus expeller-pressed canola meal (NEPCM) and B. napu...
The objective of this experiment was to determine the effects of fiber level from alfalfa meal and collection period on intestinal nutrient and energy flow, and hindgut fermentation in growing pigs. Twenty-four pigs (initial BW = 21.4 ± 1.5 kg) were prepared by T-cannula insertion into the distal ileum and allotted to 4 treatments. The pigs were provided a corn-soybean meal control diet or a di...
