NIR hyperspectral imaging for animal feed ingredient applications
… hyperspectral imaging (NIR HSI) was explored for animal feed applications. Its ability to provide chemical composition of the sample at the pixel level provides an advantage over the typical NIR spectroscopy. In this dissertation, a literature review was presented that highlights the applications …

The Sorption of Roxarsone, an Organoarsenical Animal Feed Additive
The organoarsenical roxarsone is added to poultry feed to increase weight gain. Studies have shown that roxarsone does not accumulate in poultry tissue but is excreted, resulting in elevated arsenic concentrations (~40 mg/kg) in poultry litter. However, there is little understanding of the fate of …

Development of cassava (Manihot esculenta Crantz) leaf meal as an animal feed
… (Manihot esculenta Crantz) leaf meal as an animal feed. In feeding trials with broilers, improvements in performance were observed at 10% inclusion of cassava leaf meal (CLM). High levels (20 and 30%) of CLM depressed gain, feed intake and feed per gain. Weights of spleen and liver (% of …

Development and fabricatin of production mechanism for small and medium animal feed production plant
… is because the method used to produce livestock feeds is unproductive and efficient, beside lack of technology to process livestock feed. Therefore, some improvements should be made to ensure the sustainability, speed, and quality of feed stuffs with the complete specifications. Normally, …

An Evaluation of Palm-Oil Milling Effluent Treatment by Fermentation to Produce Animal Feed Protein
… produces a high protein fungal biomass, as an animal feed, to offset treatment costs. The viability of the 'Malima' system was found to depend on the value of the fungal biomass as an animal feed. Therefore the evaluation of the fungal biomass as a protein ingredient centred on animal feeding …

Evaluation of conditions for quantitative recovery of a drug from animal feed using supercritical fluid CO₂ extraction
… hypolipidemic drug (tradename xenalipin) from an animal feed matrix. Initial emphasis of this study focused on the recovery of xenalipin from a the animal feed matrix employing a liquid solvent trap. By studying the effect of time of extraction versus recovery of drug, the liquid trap was shown to …

Nutrient profile, functional properties, and microstructure of dried waste milk products for use as a potential animal feed
… of a butter/powder factory for use as an animal feed. Two concentrated products were evaluated: recovered milk product (RMP), which is the direct factory waste stream; and formulated recovered milk product (FRMP), which is a product made by combining RMP and separator de-sludge in a 3:1 …

Evaluation of biomass from the halotolerant microalga Dunaliella salina as an animal feed additive with immune-modulatory activity
… sourced from Dunaliella salina for use as an animal feed additive. Dunaliella salina is the richest known source of carotenoid pigments and anti-oxidants, and these have a variety of uses including as food colourants, additives for cosmetics, and nutritional or health supplements for …

Insects in animal feed: a sociological evaluation of Italian consumer preferences for fish and poultry fed with alternative feed ingredients.
… and indirectly through the production of feed for livestock. The feed production system relies predominantly on soy cultivation, but it also exploits marine resources for the production of fish oil and fishmeal used as feed in aquaculture. A promising avenue of research addressing the …

Mitigation of ammonia gas from animal house using microalgae
… potential of algae to mitigate ammonia gas from animal house and to be used as a high-value animal feed. Ammonia gas emission from animal manure decomposition is a major concern in animal housing operations. Excessive ammonia gas volatilization will affect both animal and worker health and can …

STRUCTURE-FUNCTION STUDIES OF MULTIPLE INOSITOL POLYPHOSPHATE PHOSPHATASES FROM GUT COMMENSAL BACTERIA
… is the main storage form of phosphorous in animal feeds. Phytases are enzymes (myo-inositol hexakisphosphate phosphohydrolases) that break down InsP6 by hydrolysis to release inorganic phosphate. Non-ruminant animals do not produce phytases needed to digest dietary InsP6, instead relying on …

Leaf protein concentrate from paunch grass and green waste: A technoeconomic analysis and lifecycle assessment
The global supply of food and feed protein needs to double during the first half of the 21st century. At present, food and feed protein is produced by livestock and arable crop farming. Further expansion of this protein production model is unsustainable in many countries due to overallocated water …

Strategies for sustainable livestock production in Brazil and the European Union
… in the tropics through the global trade in animal feed. This thesis therefore evaluates two strategies for shrinking the environmental impact of the livestock sector. First, I evaluate the potential for food losses (i.e. foods which were intended for human consumption, but which ultimately …

Self-selection of animal by-product by poultry through utilization of choice feeding
"The emergence of animal welfare provisions by humane societies has limited management practices. One of these provisions is the animal's freedom to express normal behavior. Animal by-product feeding to livestock and poultry is a common management practice and it is stigmatized in the public eye …

The economic potential of establishing a poultry litter handling industry
… to absorb more litter for fertilizer and animal feed (litter-deficit areas). A linear programming feed cost minimization model was used to estimate the value of litter as a feed for beef stockers and beef cows. The value of litter in beef and stocker rations were estimated by determining …

Investigation of dried distillers grains with solubles (DDGS) susceptibility to red flour beetle (Tribolium castaneum (Herbst)) infestation
<p>Protecting livestock feed from insect infestation is a common challenge that feed facility managers and farmers have to deal with. It becomes an issue of importance because insect infestation degrades feed quality and quantity. Dried Distillers Grains with Solubles (DDGS) is added to livestock …
