Model Of Dietary Fiber Utilization By Small Mammalian Herbivores, With Empirical Results For Neotoma, Felisa A. Smith, Keith E. Justice

Biology Faculty & Staff Publications

Allometric considerations have suggested that small herbivores are inefficient at or incapable of extracting energy from the microbial fermentation of structural carbohydrates. This notion is at odds with accumulating empirical evidence that demonstrates well-developed fiber digestion abilities for a number of small rodent genera. To examine the apparent inconsistency, we have constructed a model of plant fiber utilization tailored specifically for hindgut fermenters. Computer simulations provide estimates of fiber and overall dry-matter digestibilities as a function of body size, energy demand, and diet. Our calculations indicate that small mammals can obtain significant benefit from fiber fermentation, especially at moderate fiber …

Effect Of Source And Level Of Supplemental Protein On Performance Of Postpartum Range Cows, M. C. Namminga, R. J. Pruitt

South Dakota Beef Report, 1992

Two postpartum grazing trials were conducted from early March to mid May in consecutive years to determine the effects of supplemental rumen escape protein on the performance of spring calving beef cows grazing native range. Simmental x Angus cows were allotted within 7 to 14 days of calving to three supplement treatments formulated to provide equal amounts of energy from corn, soybean meal, and a combination of blood meal and corn gluten meal. Cows supplemented with corn lost more weight than cows supplemented with soybean meal. Supplemental escape protein did not improve weight gains over the soybean meal supplement. Supplemental …

Chaps Summary For South Dakota, 1991, D. L. Boggs

South Dakota Beef Report, 1992

Calving distribution and calf performance data were summarized from the CHAPS (Cow Herd Appraisal of Performance Software) analyses of 61 South Dakota cow herds. CHAPS uses beef cow weaning weight records to calculate adjusted 205-day weights and ratios, keep lifetime production records on cows, calculate Most Probable Producing Ability estimates for cows, produce a sire summary and analyze production according to cow age and 21 -day calving periods. The 1991 summary represents 6,196 cows for an average of 102 cows per herd. The herds ranged in size from 19 to 277 head. The average midpoint of the calving season for …

Cyanonews (Vol. 8, No. 2, July 1992), Jeff Elhai

CyanoNews

CyanoNews was a newsletter that served the cyanobacteriological community from 1985 to 2003, with content provided by readers (sort of a blog before there were blogs). The newsletter reported new findings from the lab, summaries of recent meetings (often provided by graduate students and post-docs entering the field), positions sought or available, life transitions, a compendium of recent cyanobacteria-related articles, and other items of interest to those who study cyanobacteria.

Scanning Electron Microscopy And Ultraviolet Absorption Microspectrophotometry Of Plant Cell Types Of Different Biodegradabilities, D. E. Akin, L. L. Rigsby

Food Structure

Phenolic components within cell walls are the greatest limitation to biodegradation of plants, but the location and types of compounds within specific walls are poorly understood . Leaf blades of warm-season (Coastal and Coastcross-1 bermuda grasses and sudangrass) and cool-season grasses (orchardgrass and tall fescue) and leaflets of legumes (alfalfa and lespedeza) were evaluated before and after incubation with rumen microorganisms for 7 days to determine cell types and wall structures most resistant to biodegradation. UV absorption microspectrophotometry was used to characterize aromatics within selected undegraded cell types, which had been shown in digestion studies to vary in biodegradability, from …

Rp92-438 Food Additives: What Are They?, Patricia Redlinger, Diane Nelson

University of Nebraska-Lincoln Extension: Historical Materials

Fewer and fewer Americans produce their own food, yet consumers demand and enjoy a food supply that is flavorful, nutritious, convenient, readily available, safe, abundant, varied, and reasonably priced. Food additives and technology make that possible.

This research publication covers what food additive are, why are they used, how they are regulated, and what can individuals do when they are concerned about food additives. It also contains a guide to food additives table.

Scanning Electron Microscopy Structure And Firmness Of Papain Treated Apple Slices, Yaguang Luo, Max E. Patterson, Barry G. Swanson

Food Structure

'Mcintosh' apple (Malus domesrica Borkh.) slices were treated with papain. Textural changes were recorded with an Instron Universal Testing Machine. Structural changes and distribution of microorganisms in apple tissues after treatment were observed with a scanning electron microscope (SEM). Apple slices submerg ed in a 1% papain solution were significantly firmer than apple slices submerged in the distilled water control for a 24 hour period (P < 0.05). Three and four days after slicing , a significantly smaller decay index was observed on the apple slices submerged in papain solution than on the control slices. Under SEM, less severe cell wall breakdown was observed on the apple tissues treated with papain than on apple tissues without treatment. Less spores were also observed on the papain treated apple slices than apple slices without treatment. Apple tissues treated with papain solution and distilled water also demonstrated noticeable st ru ctural differences. The apple tissues treated with papain solution for 18 hours retained the original cell structure while the cells in the apple tissues treated with distilled water collapsed.

G92-1120 Fire Blight Of Apple, Pear And Woody Ornamentals, John E. Watkins

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide tells how fire blight is spread among apple, pear and woody ornamentals. It describes the disease cycle and offers advice for treatment and protection.

Fire blight, caused by Erwinia amylovora, is the oldest, most serious bacterial disease of apple and pear. It was first reported in the late 18th century in the Hudson River Valley in New York. The disease is indigenous to North America, and probably occurred on native American plants such as crabapple, hawthorn and mountain ash and then spread to susceptible cultivated apples, pears and woody ornamentals planted by the early American pioneers. As …

Phosphorus Sorption By Gravels In Lateritic Soils, D. M. Weaver, G. S.P. Ritchie, R. J. Gilkes

Food Science and Nutrition

The effect of sesquioxidic gravels (>2 mm size fraction) on phosphorus sorption by two gravelly lateritic soils was investigated by phosphorus sorption experiments, X-ray diffraction, autoradiography and electron microscopy.In one soil the abundance and size of gravels decreased downslope. As the gravel content of both soils increased (13-61%), the proportion of large (>8 mm) gravels increased (0-70%). Phosphorus sorption increased in the order: (>2 mm fraction) < (whole soils) < (2 mm) decreased with increasing gravel size and increased with increasing time. Phosphorus sorption by whole soils decreased with increasing gravel content. Phosphorus sorption by the >2 mm fraction was principally by the external surfaces of the gravels. The estimation of phosphorus application rates for lateritic soils depended on the amount of phosphorus required by the plant …
