Infection Of Oriental Mustard By Nematospora: A Fluorescence And Scanning Electron Microscope Study, Richard A. Holley, Beverley E. Phipps-Todd, Suk H. Yiu

Food Structure

Fluorescence light microscopy and scanning electron microscopy were used to study penetration by the yeast Nematospora caryli through the seed coat and into the embryonic tissues of oriental mustard seed (Brasslca iuncea).

Infection of the seed was associated with its physical injury; however, it was evident that the yeast was capable of successfully invading healthy plant cells. The pathological process was followed in parallel using both the above types of microscopy. Foci of yeast infection on the seed coat outer surface were characterized by swelling of the infected epidermal cells. Nematospora hyphae were seen in the lumina of the seed …

B-Glucans In The Caryopsis Of Sorghum Bicolor (L.) Moench, C. F. Earp, C. A. Doherty, R. G. Fulcher, L. W. Rooney

Food Structure

Fluorescence microscopy was used to determine the location of B- glucans in sorghum. Sections from three genetically different sorghum cultivars were stained with Calcofluor or Congo Red , fluorochromes which have been reported to react with 13-glucans. Autofluorescence, indicative of ferulic acid in other cereals, was observed in untreated sections. When stained sections were treated with endo -B-glucanase , fluorescence was reduced or entirely eliminated in pericarp, aleurone and endosperm cell walls. 13-Glucans were i so lated from the endosperm of three sorghum cultivars. When reacted with the two dyes, Calcofluoror Congo Red , precipitates formed immediately, a reaction which …

Evaluation Of Selected Properties Of Chlorinated Wheat Flours In A Lean Cake Formulation, J. Grider, E. A. Davis, J. Gordon

Food Structure

Cake flours treated with different levels of chlorine were evaluated by use in a Kissell cake formulation. Flour particle size distributions varied with chlorination level, but pH and specific gravity of the batters did not differ. Batter viscosity differences were observed at specific temperatures during heating of total batters. Temperature profiles differed positionally in the cakes, but these patterns of heat penetration were not related to level of chlorine treatment. However, water loss rates differed depending on the level of chlorine treatment indicating a more pronounced effect of chlorination level on the water loss characteristics of the cakes during the …

1983 Annual Report

Southeast Research and Extension Center: Reports and Administration

1983 was another interesting year for the staff of our unit, our clientele and for those of us involved in administration.

On the agricultural front, the fall and winter of 1982 and the spring of 1983 were very wet; while July, August, and September were very, very hot and dry.

The PIK (Payment In Kind) added a dimension of uncertainty, but did have a positive effect on prices. Over 50% of the cropland was retired in some of the counties in southeast Nebraska.

Unfavorable economic conditions strained the financial stability of many farmers and businesses in our district. Unemployment climbed …

The Foraging Behavior Of Lacewing Larvae On Vertical Rods, Alan B. Bond

Alan Bond Publications

The foraging behavior of lacewing larvae (Chrysopa carnea Stephens, Chrysopidae, Neuroptera) on vertical lucite rods was observed under a variety of experimental conditions to investigate the decision processes responsible for the distribution of foraging effort. Food deprivation increased the duration of searching on all parts of the rod, whereas contact with prey at the rod tip induced only a local enhancement of searching activity. Searching at the rod tip did not decline with repeated trials on the same rod, but the duration of searching on the rest of the rod was reduced, evidently reflecting recognition and avoidance of previously-searched …

Cranes Of The World: 6. Aviculture And Hybridization, Paul A. Johnsgard

Cranes of the World by Paul A. Johnsgard

The keeping of cranes in captivity, either as pets or as animals to be fattened for the pot, is evidently a very old practice. Captive cranes are depicted on the walls of the Temple of Deir-el-Barari of the Nile Valley, where cranes are shown walking in stately fashion between slaves. Each crane's bill is tied down close to its neck, which would upset its balance and thus prevent it from flying away (Whymper, 1909). Armstrong (1979) noted that cranes were apparently domesticated in ancient Greece, and that Plutarch (c. A.D. 46-c. A.D. 120) mentions the nesting of tame cranes, presumably …

Cranes Of The World: 7. Endangered Species And Conservation, Paul A. Johnsgard

Cranes of the World by Paul A. Johnsgard

Few families of birds, other than some associated with small island archipelagos, have such a large proportion of their species in danger of extinction as does the crane family. Of the 14 extant species of cranes, King (1979) regards two full species (whooping crane and Siberian crane) as endangered, three more (Japanese, hooded, and white-naped) as vulnerable, and the black-necked crane as of indeterminate status. Additionally, one race (the Mississippi) of the sandhill crane is classified as endangered, and the Cuban race is regarded as rare and local. Thus, more than a third of the world's crane species are currently …

The Effects Of Limited Food Availability On The Striped Bass Fishery In Lake Mead, John R. Baker, Larry J. Paulson

Publications (WR)

The original range of striped bass (Morone saxatilis) was along the Atlantic Coast. They were introduced into the lower Sacramento River in 1879 and are now also found along the Pacific Coast. A landlocked striped bass fishery was established in Santee-Cooper Reservoir, South Carolina, in 1954, and they have since been introduced into numerous other reservoirs, including Lake Havasu, Lake Mead and Lake Powell on the Colorado River. Striped bass were introduced into Lake Mead in 1969 in response to declines in the largemouth bass (Micropterus salmoides) fishery that occurred during the 1960s and in order to further utilize the …

"Dried Fat" For Growing-Finishing Swine, K. E. Keaschall, B. D. Moser, E. R. Peo, Jr., A. J. Lewis, T. D. Crenshaw, Win Butler

Department of Animal Science: Faculty Publications

Three trials were conducted to determine the effect of "dried fat" (fats absorbed on carriers) in diets for growing-finishing swine. In trial I pigs receiving diets containing 5% added fat gained faster (.74 vs .71 kg/d), consumed less feed (1.87 vs 2.43 kg/d) and had a better feed efficiency (2.52 vs 2.88) than pigs fed diets without added fat (all P<.01). Pigs given the "dried fat" treatments gained faster (P<.01) and more efficiency (P<.01) than pigs fed the nonfat carrier counterpart. "Dried fats" containing whey plus fat and wheat bran plus fat produced similar performance to that observed with pigs fed a conventional tallow diet.

Growth And Activity Of Juvenile Mosquitofish: Temperature And Ration Effects, Wayne A. Wurtsbaugh, J. Cech

Watershed Sciences Faculty Publications

The effects of constant temperatures (10, 15, 20, 25, 30, and 35 C) and ration size on the growth rates and activity of juvenile mosquitofish Gambusia affinis (mean wet weight, about 20 mg) were measured in laboratory experiments. On ad libitum rations of Tubifex spp. worms, food-consumption rates of mosquitofish were very high, ranging from 7% dry body weight/day at 10 C to 83%/day at 35 C. Growth increased from 0% dry body weight/day at 10 C to 21%/day at 30 C and declined slightly at 35 C. Gross efficiencies (100 growth/food consumption) increased from 0 at 10 C to …

A Nutritional And Morphological Study Of Two Cyanobacteria Free Azolla Ferns, Michael Paul Bonner

Theses and Dissertations

The symbiotic association between the aquatic water fern Azolla and its symbiont, Anabaena azollae Straus. has been extensively studied in the past ten years. The cyanobacteria has received much of the attention due to its ability to fix atmospheric nitrogen while the fern free of the cyanobiont has been somewhat neglected. The purpose of this research was to determine the nutritional requirements of the cyanobacteria free (CBF) ferns and study the morphology of the leaves and branches of these CBF ferns.

Azolla filiculoides and Azolla pinnata were freed of the cyanobiont using the surface sterilization technique adopted from Duckett, et …

The Use Of Whole-Rolled Sunflower Seeds With Or Without Additional Limestone In Lactating Dairy Cattle Rations, Anne M. Finn

Electronic Theses and Dissertations

Thirty Holstein cows were utilized in a lactation trial evaluating diets containing whole-rolled sunflower seeds. Cows were randomly assigned to treatments, grouped according to previous milk production and lactation number. The cows were fed one of three diets: 1) the control was a com-soybean meal mix (CSM), 2) com-soybean meal mix plus 22% whole-rolled sunflower seeds, and 3) a corn-soybean meal mix with 22% whole-rolled sunflower seeds with an additional 3.5% limestone over SCS (SCL). Additional limestone was added in an attempt to form fatty acid insoluble soaps. Rations were formulated to be isonitrogenous at 16% crude protein, fed as …

In vitro dry matter digestibility (IVDMD) of sunflower hulls (SFH) treated with sodium hydroxide (NaOH), ammonium hydroxide (NH₄OH), and potassium hydroxide (KOH) at increasing levels were studied. Tested concentrations of each alkali as percent dry matter (DM) on SFH were 1.63, 2.45, 3.26, and 4. 08. In vitro dry matter digestibility of sunflower hulls increased with higher concentrations of NaOH and KOH. Percent IVDMD for control (un-treated SFH) was 18.0. Percent IVDMD for SFH treated at 1.63, 2.45, 3.26, and 4.08% of DM were: 18.9, 21.4, 22.2, and 22.9 for NaOH; 18.3, 18.0, 18.3, and 18.5 for NH …

An Examination Of Prostaglandins As Causative Agents In Pine Needle (Pinus Ponderosa) Abortion, Daniel P. Shue

Electronic Theses and Dissertations

Cow and calf losses due to pine needle abortion in cattle grazing foothill ranges of ponderosa pine (Pinus ponderosa) continue to cause managerial and economic problems for ranchers in South Dakota, Colorado, Idaho, California, Montana and many areas throughout Canada. Because of its overall economic significance, investigators have been attempting to isolate and characterize causative agents of pine needle abortion. To date, a large number of pine needle constituents have been shown to possess abortifacient capabilities. In addition to actual pine needles, it appears that several other undefined factors may be associated with, and (or) predispose animals to, pine needle …

Ultrafiltration Of Skim Milk Prior To Cottage Cheese Making, Izhar H. Athar

Electronic Theses and Dissertations

Cottage cheese has the largest sales volume potential of all cultured dairy products in the United States today. Moreover, it can be a highly profitable product if proper control is exercised during its manufacturing (46). Commercial production of cottage cheese utilizes a significant portion of the total fluid milk produced in the U. S.A. After the 1955's, yearly per capita consumption of cottage cheese increased from 1. 7 7 kg (3.9 lb) to a high of 2. 45 kg (5.4 lb) in 1972 (67) . Consumer demand for lower fat dairy products gradually increased, which put more pricing emphasis on …
