Intraspecific competition is one of the major factors that can have an effect on the resources utilized within a habitat. Differences in diet quality of selected forage have been noted in size-dimorphic ungulates. However, on an intraspecific basis, data demonstrating a body size influence on diet quality are lacking. We examined diet quality across a range of body masses (14–76 kg) in white-ta...

Dietary fiber has been defined as the part of material in foods impervious to the degradative enzymes of the human digestive tract. The dietary fiber of plants is comprised of carbohydrate cornpounds including cellulose, hemicellulose, pectin, gums, rnucilages, and a noncarbohydrate substance, lignin. These substances, which form the structure of plants, are present in the cell walls of all par...

A 49-d feeding trial, using 192 growingfinishing pigs (avg initial wt, 32 kg), was conducted to identify pigs of widely differing average daily gains (ADG) when fed 16% crude protein diets containing either 0, 7.5 or 15% corn cobs. There were linear decreases in both ADG (P<.01) and gain/feed (P<.001) with increasing levels of dietary corn cobs. Average daily feed intake increased linearly (P<....

The effects of feeding diets containing 20% (L) or 30% (H) neutral detergent fiber (NDF) (DM basis) on performance and carcass traits were studied in three breeds of pig, including pure Mong Cai (MC), crossbred Landrace×Yorkshire (LY) and crossbred MC×Yorkshire (F1). The experiment had a factorial design with two factors, breed and diet. Eighteen piglets of each breed (60±3 days) were randomly ...

The role of dietary fiber in counteracting the toxic effect, and significant growth retardation, of some non-ionic detergents added to the diet has been observed by Ershoff et al. (1, 2), but the mechanism by which these chemicals and dietary fiber exert their effects on the physiological functions has remained unclear. We recently supposed that the primary toxic effect of these chemicals was t...

The effect of neutral detergent fiber (NDF) from coconut kernel (Cocos nucifera L) in rats fed 5%, 15% and 30% level on the concentration of blood glucose, serum insulin and excretion of minerals was studied. Increase in the intake of fiber resulted in significant decrease in the level of blood glucose and serum insulin. Faecal excretion of Cu, Cr, Mn, Mg, Zn and Ca was found to increase in rat...

OBJECTIVE To evaluate the impact of fat and fiber intake on energy and nutrient intake of 15-year-old adolescents. STUDY DESIGN Twenty-four-hour dietary recalls were collected on a random sample of 15-year-olds. Subjects were then categorized into groups based on fat and fiber intake, with 319 students meeting criteria for 1 of 4 dietary intake quadrants: low fat, low fiber; low fat, high fib...

An extensive series of studies have been conducted during the past 20 years indicating the beneficial effects of alfalfa and other plant fiber-containing materials in counteracting the toxic effects of a number of drugs, chemicals, and food additives when administered at high doses to animals fed highly purified, low-fiber diets (1-9). The protective factor or factors in these fiber-containing ...

BACKGROUND Dogs suffer from many of the same maladies as humans that may be affected by the gut microbiome, but knowledge of the canine microbiome is incomplete. This work aimed to use 16S rDNA tag pyrosequencing to phylogenetically characterize hindgut microbiome in dogs and determine how consumption of dietary fiber affects community structure. PRINCIPAL FINDINGS Six healthy adult dogs were...
