The following work was performed with the idea of taking advantage of the zone’s native species as a source for the feeding of llama cattle. In order to accomplish it, we took into consideration the following variables: food consumption, water consumption, amount of fecal excretions, urine volume, body weight, and the digestibility of the nutrients found in the food prepared with paja brava and barley (ash, protein, fiber, …

Fisheries Research Contract Report No. 8 - The Nutritional Management Of Barramundi, Brett Glencross

Fisheries Research Contract Reports

Barramundi nutrition research has been undertaken since 1988. Since that time the requirements for most nutrients, energy demand, ingredient utilisation and the effects of nutrition on flesh quality aspects have all been examined to varying extents.

Optimal protein content of diets has been shown to vary with diet energy density and also the size of fish which are being fed. Most studies have suggested a protein requirement from 45% to 55%. For small fish a protein to energy ratio of 25 to 30 g/MJ is suggested. Limited work has been done on fish larger than 500 g. The 10 essential …

Body Mass Index And Soft Drink Consumption Among Adolescents, Olivia Love Mccord

Theses and Dissertations

Objective: To determine the relationship between body mass index (BMI) and soft drink consumption among adolescents. It is hypothesized that soft drink consumption contributes to overweight and obesity among adolescents.

Background: Research examining the relationship between body mass index and soft drink consumption is inconsistent. Several studies have found a negative association between total sugar intake and BMI; however, others have found a link between sugar-sweetened drinks and obesity. There are no known studies that have controlled for physical activity.

Data and Methods: Data on approximately 225 adolescents were used. Frequency of soft drink consumption, type of milk, and calcium …

Determination Of The Nutritional Level Of Calcium And Phosphorus In Llamas (Lama Glama) In Two Seasons In The Condoriri Agricultural Experiment Center, Gustavo Adolfo León Titichoca

Theses and Dissertations

The concentrations of calcium and phosphorus were determined in 12 llamas from the Condoriri Agricultural Experiment Center (Oruro Technical University) of Oruro, Bolivia during two seasons (wet and dry) and at three ages (newborn, juvenile, and adult). Samples of flesh were taken from the arm, leg, back, rib, and neck. Pasture samples (grassland and prairie) were used to determine the rate of biting of each animal studied. The blood samples were taken by extracting blood from a jugular vein. The minerals (Ca and P) in the flesh are highest in the wet season, 113.78 mg/100 g. The newborns were found …

Nf04-606 Deep Fat Frying Turkeys, Carol J. Plate

University of Nebraska-Lincoln Extension: Historical Materials

Deep fat frying began in the southern part of the United States and has gradually spread nationwide. Turkeys are the most common food prepared by this method. However, chicken, turkey parts (breasts, wings and thighs), and Cornish game hens may be deep fat fried. Deep fat frying results in a juicy product because the hot fat seals the outside and the skin becomes crisp.

This NebFact talks about the equipment, ingredients, preparation, frying, and safety of deep fat frying turkeys and other poultry.

Phospholipase A2 In Salivary Glands Isolated From Tobacco Hornworms, Manduca Sexta, Hasan Tunaz, David W. Stanley

Department of Entomology: Faculty Publications

We describe a phospholipase A₂ (PLA₂) associated with the salivary glands of tobacco hornworms, Manduca sexta. This enzyme is able to hydrolyze arachidonic acid from the sn-2 position of PLs. Addition of the calcium chelator, EGTA, or calcium, to the Tris reaction buffer impaired the PLA₂ activity, from which we infer the enzyme requires very low concentrations of calcium or perhaps other ions for optimal activity. PLA₂ activity was sensitive to protein concentration (highest activity at 25 μg protein per μl), reaction time (optimal at 30 min), buffer pH (optimal at pH 8–10), …

Diet Quality And Food Limitation Affect The Dynamics Of Body Composition And Digestive Organs In A Migratory Songbird (Zonotrichia Albicollis), Barbara J. Pierce, Scott R. Mcwilliams

Biology Faculty Publications

Migrating songbirds interrupt their feeding to fly between stopover sites that may vary appreciably in diet quality. We studied the effects of fasting and food restriction on body composition and digestive organs in a migratory songbird and how these effects interacted with diet quality to influence the rate of recovery of nutrient reserves. Food limitation caused whitethroated sparrows to reduce both lean and fat reserves, with about 20% of the decline in lean mass represented by a decline in stomach, small intestine, and liver. During refeeding on diets similar in nutrient composition to either grain or fruit, foodlimited grain-fed birds …
