1992 Beef Cattle Report, Darrell W. Nelson

Nebraska Beef Cattle Reports

Economic efficiency of beef production to weaning and to slaughter was estimated in three groups, different in milk available (low, medium, and high) to the calves but the same in growth potential. Efficiency was the ratio of income to expenses. Income was derived from cull cows and calves at weaning or carcasses of calves fed to slaughter. Feed and non-feed expenses for the cowherd and for calves to weaning or to slaughter were included. Efficiencies were estimated assuming observed reproductive rates and energy requirements for maintenance, as well as for equal reproductive rates and equal requirements for maintenance in the …

Food Handling Practices Among Independent-Living Elderly, Judith Dianne Mcdonough

Loma Linda University Electronic Theses, Dissertations & Projects

Food has long been recognized as a vehicle of disease transmission; there are more reported illness associated with the consumption of food than all other environmental factors combined. The handling and storage of food are potentially dangerous and demanding chores for those who may have the sensory losses associated with advancing age, fragile health, and limited resources.

Group-administered questionnaires on the knowledge, attitudes, and practices of food handling were given to 276 seniors, aged 55 to 90, from ten mobile home parks randomly selected from San Bernardino and Riverside counties. As an indicator of possible foodborne illness, the questionnaire asked …

The Effects Of A Commercial Nutritional Supplement Combining Amino Acids, Glutamine, Carnitine And B-Vitamins On The Physiological Responses To Ultraendurance Triathlon Training, Performance And Recovery, Mary V. Mitchell

Human Movement Studies & Special Education Theses & Dissertations

In a placebo, double blind, randomized design, five male triathletes participated in a simulated triathlon which examined the physiological responses of a commercial nutritional supplement. The supplemental protocol included 7.1 gm·d^-1 of an amino acid complex with B-vitamins (AA) and between 2.2-7.3 gm·d^-1 META-MAX™ containing leucine, isoleucine, valine, glutamine and carnitine in which quantities were based on the athletes training volume. A maltodextrin carbohydrate replacement drink was also included in the protocol. The placebo was an isocaloric lactose substance. The supplements were ingested for 14 d prior to the simulated triathlon and then for 3 d after the …

The Scanning Electron Microscope: How Valuable In The Evaluation Of Small Bowel Mucosal Pathology In Chronic Childhood Diarrhea?, J. Rainer Poley

Scanning Microscopy

Data are presented on scanning electron microscopy (SEM) on small intestinal biopsies of children with chronic diarrhea. In particular, there were 230 patients aged 3 months to 13 years with the following diagnoses: chronic nonspecific diarrhea, cow's milk protein intolerance, soy protein intolerance, giardiasis, cystic fibrosis, gluten-sensitive enteropathy, isolated lactase deficiency, isolated sucrase-isomaltase lactase deficiency, microvillus inclusion disease, rotavirus ententis, protracted diarrhea of infancy, chylomicron retention disease, visceral myopathy and villous asthenia.

Examination of biopsied intestinal mucosa by SEM has yielded important new information and insights on structural pathology and ultrastructural topography. Many of the observed changes helped to better …

Enhanced Attraction To Blood By Pigs With Inadequate Dietary Protein Supplementation, David Fraser, D. E. Bernon, R. O. Ball

Nutrition Collection

In two experiments, 60 individually penned growing pigs were exposed daily to two sections of cotton cord, one of which had been soaked with pigs' blood and subsequently dried, while the other was plain. The animals' preference for chewing-on the blood-impregnated cord was quantified by direct observation. When fed a standard "control" diet of corn, barley, and soybean meal with mineral and vitamin supplements, the pigs had a clear but modest preference for chewing the blood-impregnated cord. Omission of the protein supplement (soybean meal) from the diet for 4 wk led to a major increase in attraction to blood and …

Bulletin No 4225 - Dairying In Western Australia, Dean Maughan

Bulletins 4000 -

Dairying in Western Australia is a small though very efficient industry. In 1989/90, 480 dairy farmers produced 266 million litres of milk for an estimated return of $84 million. The retail value of milk and dairy products was estimated to be $250 million making dairying a very significant industry in the south-west of Western Australia.

The Physiology And Molecular Biology Of Iron Nutrition For Cyanobacteria, Nancy Walters Unsworth

Dissertations and Theses

In addition to nitrogen and phosphorus, iron is an essential nutrient for oceanic primary productivity. Unlike nitrogen and phosphorus however, negligible amounts of iron are supplied to surface waters through recycling or mixing but instead from the limited and sporadic input of aeolian particulate. The low concentration of iron that becomes biologically available from the dust places a serious constraint on the heavily iron-dependent processes of photosynthesis and nitrate reduction which affect primary productivity. As much as 47% of the total oceanic primary productivity can be attributed to cyanobacteria making them critical organisms in the biogeochemical cycles. This thesis addresses …

Distribution Of Sexual Activities Within Estrus Of Dairy Cattle, Donna Durbin

Masters Theses & Specialist Projects

Previous studies of dairy cattle have indicated that heifers and cows in hot, cold and moderate weather had different patterns of sexual activities. The purpose of this study was to compare distribution of sexual activities within estrus of dairy cattle. Three groups of lactating cows in hot, cold and moderate weather and a group of heifers in cold weather were observed. Estrus for each individual was divided into 12 equal periods. Sexual activities for 3 and 6 hours before and after estrus were also observed. The numbers of mounts and distribution of total sexual activities was analyzed. Mounts received per …

Nutritional Complementation Of Oxidative Glucose Metabolism In Escherichia Coli Via Pyrroloquinoline Quinone-Dependent Glucose Dehydrogenase And The Entner-Doudoroff Pathway, Michael Adamowicz, Tyrrell Conway, Kenneth W. Nickerson

Papers in Microbiology

Two glucose-negative Escherichia coli mutants (ZSC113 and DF214) were unable to grow on glucose as the sole carbon source unless supplemented with pyrroloquinoline quinone (PQQ). PQQ is the cofactor for the periplasmic enzyme glucose dehydrogenase, which converts glucose to gluconate. Aerobically, E. coli ZSC113 grew on glucose plus PQQ with a generation time of 65 min, a generation time about the same as that for wildtype E. coli in a defined glucose-salts medium. Thus, for E. coli ZSC113 the Entner-Doudoroff pathway was fully able to replace the Embden-Meyerhof-Parnas pathway. In the presence of 5% sodium dodecyl sulfate, PQQ no longer …

The Tall Fescue Endophyte, Don Ball, Garry D. Lacefield, Carl S. Hoveland

Agriculture and Natural Resources Publications

Tall fescue (Festuca arundinacea Schreb.) is the most important cool-season grass in the United States, providing the primary ground cover on some 35 million acres. It is a versatile perennial used to provide pasture and hay for livestock, for various turf purposes, and for erosion control. Commonly referred to as simply "fescue," this widely adapted, persistent grass is seed propagated, tolerant of a wide range of management regimes, and it produces good forage yields. Laboratory nutritive analyses of fescue compare favorably to those of many other cool-season grasses.

Histomorphometric Analysis Of Primate Periodontal Tissues Following Corticotomy In Orthodontics, Wuiteng Koh

Loma Linda University Electronic Theses, Dissertations & Projects

The purpose of this study was to evaluate the prevalence of specific cell types and structures at the active tooth movement site in corticotomized and non-corticotomized specimens obtained from a previous study, and to consider the hypothesis that corticotomy facilitated orthodontics is efficacious due to an inflammatory response rather than tooth-bone block movement. Specimens from 3 monkeys, each of which had a treatment and control quadrant in each arch, were sectioned, mounted on glass slides, and stained with Giemsa, haematoxylin, and Safranin stains. A histomorphometric analysis was performed with DataVoice™, a voice activated computer system which allowed for digitization of …

Serum Vitamin B-12 Levels And Urinary Methylmalonate Excretion In Total Vegetarians, Shari H. Patchett

Loma Linda University Electronic Theses, Dissertations & Projects

The purpose of this research project was threefold: 1) to determine the present serum vitamin B-12 status in a select group of strict or total vegetarians all of whom had been vegetarian for six months or more. 2) to determine the daily intake of vitamin B-12, total calories, protein, % calories as fat, folic acid, and crude fiber on a total vegetarian diet. 3) to observe if subjects with low serum vitamin B-12 levels and low intakes of oral vitamin B-12 also had elevated methylmalonic acid (MMA) in the urine.

Six of the 19 serum vitamin B-12 levels were below …

Effect Of Age On The Structure Of Meissner Corpuscles In Forepad Digital Pads Of Mice, Roger C. Mathewson

Loma Linda University Electronic Theses, Dissertations & Projects

Meissner corpuscles in forepaw digital pads of albino mice were examined by light and electron microscopy to determine structural age-changes. After 1.5 months of age, no intraepidermal nerve fibers were seen extending from corpuscles. From young (1.5-6 months) to middle age (9-15 months), corpuscles became larger and more complex, gaining more horizontally arranged terminals, associated lamellae and connective tissue. At old age (18-26 months), corpuscles became small and lobulated, appearing disorganized. There was no loosening of the corpuscle-epidermal interface. An increase in collagenous connective tissue and basal lamina duplication occurred with advancing age. Ultrastructural age-changes consisted of disorganization of the …
