Prediction Of Zinc Deficiency In Navy Beans (Phaseolus Vulgaris) By Soil And Plant Analyses, J. D. Armour, A. D. Robson, G. S.P. Ritchie

Food Science and Nutrition

Navy beans (Phaseolus vulgaris cv. Gallaroy) were grown with 7 rates of zinc (Zn) in a Zn-deficient gravelly sandy loam in a glasshouse experiment. The plant shoots were harvested 31 days after sowing and the Zn concentration in each of 4 plant parts (YL, young leaf; YOL, young open leaf; YFEL, youngest fully expanded leaf; and whole shoots) was related to the fresh weight of the shoots. The critical Zn concentrations (mgtkg) in the plant parts determined by the 2 intersecting straight lines model were 21.1 for YL (r² = 0.66), 17.1 for YOL (r² = 0.83), …

Extractable Zinc In Particle Size Fractions Of Soils From Western Australia And Queensland, J. D. Armour, G. S.P. Ritchie, A. D. Robson

Food Science and Nutrition

The zinc (Zn) content of particle size fractions of 12 mainly Zn deficient soils was measured by extraction with three contrasting extractants. The soils, which ranged from sands to a black earth, were from Western Australia and Queensland and particle size fractions (clay, silt, fine sand, coarse sand) were obtained by sieving and sedimentation after ultrasonification of soil suspended in deionized water. The extractants were concentrated HNO₃/H₂SO₄/HClO₄ (acid extractable or AE-Zn), DTPA and 0.002 M CaCl₂. For each extractant, Zn contents of the fractions and whole soils were correlated with organic …

Zinc Adsorption By A Lateritic Soil In The Presence Of Organic Ligands, P. Chairidchai, G. S. P. Ritchie

Food Science and Nutrition

Zinc adsorption by a lateritic podzolic soil was measured in the presence of 0 to 3 mmol/litre of acetate, oxalate, citrate, tricarballylate, salicylate, or catechol, or 0 to 3 mmol_c/litre of humate. Zinc remaining in solution was measured by atomic absorption spectrometry after shaking the soil for 17 h at a soil/liquid ratio of 1:5 in a 0.003 mol/litre KCl solution containing 0 to 500 μmol/litre Zn and the ligands. In the absence of organic ligands, more than 95% of the zinc was adsorbed. The amount of adsorption was linearly correlated with pH and the concentration of ZnOH …

Bacterial Gill Disease Of Freshwater Fishes, G. L. Bullock

United States Fish and Wildlife Service: Publications

Fish gills function as both respiratory and excretory organs. Basically they consist of a network of capillaries where blood is separated from the surrounding water by only one or two layers of cells. Proliferation of epithelial tissue, and later the loss of surface by the clubbing and fusing of lamellae, impair respiration and the excretion of nitrogenous waste materials, and disturb osmotic balance. Because these changes adversely affect the health of fish, the prevention and treatment of gill diseases are important in fish culture. Pathologic changes in gill tissues have been divided into five categories: (1) bacterial gill disease (BGD) …

Response By Stylosanthes Hamata And S. Scabra To Phosphate On Three Soils In The North-Kimberley Of Western Australia, A Mcr Holm, Mario F. D'Antuono

Resource management technical reports

Legume herbage mass was maximized after two or three years application of 50 kg/ha double superphosphate for both Verano and Fitzroy on Red earth soils and for Fitzroy on Yellow lateritic soils. There was increased production of Verano up to the maximum fertilizer level. Both varieties responded in the second year to residual P following application in the first year but there were no responses in subsequent years.

Conditioned Flavor Aversion: A Mechanism For Goats To Avoid Condensed Tannins In Blackbrush, Frederick D. Provenza, Elizabeth A. Burritt, T. P. Clausen, J. P. Bryant, P. B. Reichardt, Roberto A. Distel

Behavioral Education for Human, Animal, Vegetation, and Ecosystem Management (BEHAVE)

It has been hypothesized that herbivores instinctively avoid tannin-containing plant parts in response to the adverse effects of tannins on forage digestion. However, we found that goats learned to avoid condensed tannins (CTs) from blackbrush current season's growth by associating the flavor of foods containing CTs with aversive postingestive consequences. The aversive consequences experienced by goats apparently are not related to digestion inhibition and may depend on the structure of CTs and on how CTs are bound with other cell constituents. These observations suggest several areas of inquiry related to the interaction between CTs and herbivores. A better understanding of …

G90-988 A Process For Building Coalitions, Georgia L. Stevens

University of Nebraska-Lincoln Extension: Historical Materials

What should you consider in building coalitions? This NebGuide offers guidelines.

What is a Coalition?

1. A coalition is a group of organizations and individuals working together for a common purpose. There are two types of coalitions:

2. "One issue" or event coalitions only have to agree on one particular issue. The coalition is dissolved when the issue has been solved or the event has been coordinated.

"Multi issues" coalitions have related issues, such as nutrition and health, child care needs, elderly health care, or the environment. This more permanent type of coalition recognizes the value of mobilizing together for …

Seed Phosphorus : Its Effect On Plant Production, Mike Bolland, Mike Riley, Brett Thomson, Blakely Paynter, Mike Baker

Journal of the Department of Agriculture, Western Australia, Series 4

The amount of phosphorus in the seed of annual crop and pasture species influences production of plants grown from that seed. It appears the more phosphorus there is in the seed, the better the potential yield irrespective of whether fertilizer phosphorus is applied to the soil or not. This article discusses the influence of phosphorus concentration in the seed of annual crop and pasture species on subsequent production. It also explains the difference between phosphorus concentration and phosphorus content in the seed

Fisheries Research Report No. 87 - The Recreational Marron Fishery In Western Australia, Summarised Research Statistics, 1971-1987, N. M. Morrissy, C. J. Fellows

Fisheries Research Reports

The freshwater crayfish Cherax tenuimanus, called marron, provides an important recreational fishery in the south-west of Western Australia. The annual fishing catch and fishing effort have been monitored by a log book research programme and an end-of season telephone survey since the 1971/72 season.

Following the 1986/87 fishing season, the fishery remained closed for two seasons (1987/88 and 1988/89) to permit stocks to recover from the effects of high total fishing effort and unfavourable water conditions over the preceding seasons

This paper provides a detailed account of the catch and effort statistics to the close of the 1986/87 fishing season, …

Changes In The Rheology And Microstructure Of Ropy Yogurt During Shearing, J. A. Teggatz, H. A. Morris

Food Structure

Rheological and microstructural changes that occurred in ropy yogurt during shearing were observed. Yogurt made with an exopolymer-producing (ropy) strain of Lactobacillus delbrueckii subsp. bulgaricus and non-ropy strain of Streptococcus thermophilus was subjected to an increasing shear rate from 0-833 s-1 using a Haake Rotovisco RV2. Shear stress niticeably increased to a peak value and then decreased to a plateau value as the shear rate continued to increase. Samples taken at eight different shear rates were examined by scanning electron microscopy (SEM). At low shear rates, the exopolysaccharide (EPS) existed as a filamentous network attached to the lactobacilli and casein …

Scanning Electron Microscopy: Tissue Characteristics And Starch Granule Variations Of Potatoes After Microwave And Conductive Heating, J. Huang, W. M. Hess, D. J. Weber, A. E. Purcell, C. S. Huber

Food Structure

In order to determine cytological effects of microwave heating compared to conductive heating, whole potatoes were heated in a microwave oven in plastic bags for 0.5, 1 and 2 minutes and in boiling water for 5. 10 and 20 minutes. Both heating treatments caused swelling and partial disruption of starch granules. However, as observed with scanning electron microscopy, swelling patterns of starch granules were different in potatoes using the two heating processes. In conductive heating potatoes were heated from the outside to the inside. Microwave heated potatoes were heated fairly uniformly in different regions of tubers. The weight loss of …

The Role Of The Interfacial Protein Film In Meat Batter Stabilization, A. Gordon, S. Barbut

Food Structure

The microstructure of meat batters made with equal ionic strengths of NaCl, MgC1 2 , CaCl2 and KCl (IS- 0.43) and a reduced-NaCl batter (IS- 0.43) were examined by scanning and transmission electron microscopy. Micrographs revealed that fat globules with smooth and rough protein coats were present in all treatments. The roughly-coated globules were prevalent in the unstable batters. Pores were observed in the interfacial protein film (IPF) surrounding the globul es and were more prevalent in the globules with rough protein coats. Fat was seen to exude from the pores in both types of globules, Fat globules were shown …

Effect Of High-Pressure Homogenization On A Sterilized Infant Formula: Microstructure And Age Gelation, Y. Pouliot, M. Britten, B. Latreille

Food Structure

Age thickening and gelation of an Infant formula was Induced by applying high pressure homogenization prior to in-can sterilization. The Initial viscosity of the preparation increased with Increasing homogenization pressure. Thickening rate upon storage, as monitored by viscosity changes, was also proportional to the pressure applied during homogenization. Optical and electron micrographs of 6 month-old samples showed evidence of aggregation. The effect of dissociating agents on the viscosity and microstructure of these samples suggested a contribution of hydrogen bonds and calcium bridges to the gel integrity. The alteration of the mineral balance of aged samples also Indicated a gel strengthening …

Rp375 Angora Goats In The Midwest, R. M. Jordan

University of Nebraska-Lincoln Extension: Historical Materials

Angora goats and the mohair they produce are not major agricultural products in the United States and certainly not in Minnesota where there are fewer than 3,000 Angora goats. Flocks are small and often are owned by those interested in hand weaving. Nevertheless, mohair finds a ready market. In 1989, raw mohair prices in Texas were: kid hair (it's much finer), $6.50/lb; yearling hair, $2.00/lb; and adult hair, $1.00/lb. In addition, mohair incentive payments have amounted to $30 to $15 per head the past two years. These high hair prices are stimulating interest in goat production among an increasing number …

G90-962 Introducing Solid Foods To Babies, Darlene Martin

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide explains when and how to add solid foods to your baby's diet.

Good nutrition is the cornerstone of a baby's growth and development. The American Academy of Pediatrics strongly recommends breast-feeding for most full-term infants. No formula can replace the immunological protection a baby receives from colostrum -- the breast milk produced the first few days after birth. It's important to breast-feed for at least the first few weeks, even if it can't be continued for a long time. If breast-feeding is not your choice, or if it is discontinued before the baby's first birthday, commercially prepared infant …

Waterlogging : How It Reduces Plant Growth And How Plants Can Overcome Its Effects, Tim Setter, Bob Belford

Journal of the Department of Agriculture, Western Australia, Series 4

Lack of oxygen is the major cause of limited plant growth in waterlogged soils. When soils become waterlogged less gas diffuses to and from the roots through the soil pores; there are changes in concentrations of mineral elements in soil solutions; and toxic products of roots and soil microorganisms begin to accumulate. These changes adversely affect germination, growth and development of plants.

The Live Sheep Export Industry, Richard Norris, Barry Richards, Tony Higgs

Journal of the Department of Agriculture, Western Australia, Series 4

Australia's live sheep trade to Middle Eastern countries is an important export industry. However, about 2 per cent of the sheep die, mainly during the sea voyage. The Western Australian Department of Agriculture has conducted a major research programme to improve the health and welfare of sheep during live export. The programme has'examined many aspects of the export sheep industry, and a substantial part of it has focused on why sheep die during sea transport.
