Fermentation is an environmentally friendly method to improve feed quality. Fermented liquid feed and airtight stored moist crimped cereal grain systems that are of increasing importance in agricultural practice were studied. Both rely on spontaneous microbial developments with poorly understood population dynamics, resulting in unpredictable final quality. Temperature, fermentation time and in...

Five local spices (Piper guineense, Allium sativum, Afromomum melequata, Xylopia aethiopica and Tetrapleura tetraptera) were evaluated in the laboratory for their ability to protect stored maize against infestation by S. zeamais. Ground products of the spices were applied as direct admixtures at two concentration levels of 1% and 5% to assess for mortality, progeny emergence, damage and repelle...

A completely randomised design study involving 132 continental crossbred beef steers was undertaken to evaluate the effects of method of grain treatment and feed level, and grass silage feed value on animal performance, carcass characteristics and meat quality of beef cattle. Winter wheat was harvested and the grain was stored either ensiled crimped and treated with 4.5 l/t of a proprietary aci...

A brief summary of simulation techniques for recrystallization is given. The limitations of the Potts model and the Cellular Automaton model as used in their standard forms for grain growth and recrystallization are noted. A new approach based on a hybrid of the Potts model (MC) and the Cellular Automaton (CA) model is proposed in order to obtain the desired limiting behavior for both curvature...

This paper presents the application of a time-delay neural network to the detection and classification of time signatures produced by insect sounds in a stored grain silo. Conventional methodr of insect monitoring can only detecr some of rhe adulr insects and none of the larvae insects, which are the most destructive to the grain. The acoustic vibrations generated by the adult and larvae when m...

Martin, Daniel Thomas M.S., Purdue University, May 2014. Wheat Stored in Triple Layer Plastic Bags: Protection Against the Rice Weevil, Sitophilus oryzae L. (Coleoptera: Curcilionidae) and the Effect of Air Leaks on Hermetic Storage. Major Professor: Dr. Larry L. Murdock. The Purdue Improved Crop Storage system is a triple layer high-density polyethylene storage technology that has proven to be...

The expansion of dryeration may impose a further problem for insect control with protectants – the high grain temperatures during insecticide spraying. To assess the impact of this procedure on insecticide activity, maize grains at different temperatures (25, 30, 35, 40 and 45 °C) were sprayed with pirimiphos-methyl. Residue analyses were carried out every 30 days and insecticide biological act...
