This paper reviews nutrient deficiencies in agricultural crops of PNG using the literature of agronomic trials and field observations made throughout the country. Nutrient deficiencies have been investigated systematically since the mid-1950s, but research has mainly focused on export tree crops and relatively little information is available on food crops. Literature analysis and field observat...

The digestibility of amino acids and other nutrients by the pig is an important measure of efficiency when evaluating swine diets or ingredients used in swine diets. Any method of feeding or use of a feed additive that significantly increases the ileal digestibility of amino acids could be used to increase the efficiency of amino acid use by the pig, and decrease waste and nutrient losses from ...

Livestock production causes unavoidable losses to the environment, and the concerns related to aerial emissions from livestock production is ever increasing. Losses to the atmosphere occur during respiration and from fresh and stored feces and urine. These losses may be an environmental burden as contributors to global climate change (CO2, CH4), regional particulate or acid deposition concerns ...

Substantial losses of nutrients may occur during tube (gavage) feeding of fortified human milk. Our objective was to compare the losses of key macronutrients and minerals based on method of fortification and gavage feeding method. We used clinically available gavage feeding systems and measured pre- and post-feeding (end-point) nutrient content of calcium (Ca), phosphorus (Phos), protein, and f...

A field-scale plot study was conducted at Virginia Tech’s Prices Fork Research Farm, to evaluate the transport of nutrients in runoff from manure and fertilizer applied at P-based agronomic rates to cropland planted to corn. Simulated rainfall events representing 2to 10-year storms in southwest Virginia, occurring 1 and 2 days following manure and fertilizer application were used to generate ru...

UNLABELLED The short bowel syndrome (SBS) is due to loss of bowel after surgery. Characterized by generalized nutrients malabsorption, its signs and symptoms include electrolyte imbalance, deficiency of vitamins, minerals and nutrients that can lead to death. Parenteral and enteral nutrition have a key role in its treatment. OBJECTIVE To describe the clinical course of a patient with SBS duri...

Animals translocate nutrients by consuming nutrients at one point and excreting them or dying at another location. Such lateral fluxes may be an important mechanism of nutrient supply in many ecosystems, but lack quantification and a systematic theoretical framework for their evaluation. This paper presents a mathematical framework for quantifying such fluxes in the context of mammalian herbivo...

There is increasing need to store the nutrient rich amaranth leaves which are plenty during the wet season for use in dry season, but there is little information on the micronutrient stability on storage of vegetables produced in dry areas meant to bridge the seasonal gap. The stored dry leaves can be utilized during dry season by mixing them with cereal flours for making porridge for children ...

Because exercise stresses metabolic pathways that depend on thiamine, riboflavin, and vitamin B-6, the requirements for these vitamins may be increased in athletes and active individuals. Theoretically, exercise could increase the need for these micronutrients in several ways: through decreased absorption of the nutrients; by increased turnover, metabolism, or loss of the nutrients; through bio...

Nutrition is the series of processes of taking in food, breaking down the food into minute components (called nutrients or micronutrients) in the stomach, absorbing these components into the body, and having the body store or use them. The components of food are categorized according to their use in the body: carbohydrates and fats provide energy, protein builds the body, and vitamins and miner...
