Streszczenie:
Finding an alternative to fishmeal and fish oil in animal feeds has been a topic of increasing interest due to the pressures being put on the ocean’s fisheries and the increasing world demand for animal protein. An often-overlooked source of nutrients is in the form of food waste. One third of all food produced globally ends up in landfills, wasting a huge amount of nutrients and embodied energy that could otherwise be redirected towards productive use. This study investigated the feasibility of feeding Hermetia illucens, the black soldier fly larvae (BSFL), grown on urban food waste, and Lemn

The focus of this thesis was to analyze the least cost of producing rations for ducks in three age categories from a mixture of conventional feed ingredients and three different processed food waste products and to examine the financial and economic feasibility of establishing an industrial plant to produce these food waste products in the Montreal region. The first part of the thesis was investigated through the use of a linear programming model.

Food waste accounts for about 1/3 of the municipal waste generated in Hong Kong. Using food waste as major ingredients to produce fish feed pellets could ease part of the disposal pressure on the existing landfill sites.

This thesis examines the trajectory of food politics and its relationship with modernizing food landscapes. Today’s food politics discussions in the US and other high-income countries lean towards concerns with social issues, while in the recent past it was more focused on producing enough food to feed the growing population – two different situations with important concerns. The question this thesis explores is whether the modernization of society has given us a higher level of wellbeing and a better world through food landscapes and food policy, and how we came up with the current food situa

Hormones regulate numerous biological processes. Endocrine disrupting compounds (EDCs) are chemicals which are capable of altering normal hormone signaling, and as a result may contribute to a wide range of adverse health effects. Mycotoxins are one group of compounds which remain to be extensively tested for endocrine disruption. These compounds are toxic secondary metabolites of fungi, which are ubiquitous in nature and may be present in the food and feed of humans and animals, respectively.

A theory of growth and feed intake in the pig is proposed and the results of five experiments to test it are reported here. An attempt is first made to describe the potential growth in pigs, that is, growth under non-limiting conditions; the conditions needed to allow potential growth to be retained are then considered. Two ways of providing non-limiting feeding conditions are discussed: a single balanced feed and a set of feeds given as a choice. In addition, a model which predicts the voluntary feed intake of pigs is also developed and tested in experiments. The results from pigs offered sin

Thesis (MTech (Food Technology))--Cape Peninsula University of Technology, 2016.<br>The aim of this study was to evaluate Bambara groundnut (BGN) milk subjected to spray drying with a view to establish functional, nutritional and physical properties as an ingredient in BGN yoghurt production. BGN milk powder (BGNMP) was successfully produced employing the spray drying technology. Maltodextrin was used as the drying carrier to elevate total solids of BGNM prior to spray drying. There were three levels of maltodextrin (5, 10 and 15%) employed and 10% was ideal. The optimum spray drying parameter

Thesis (Ph.D. (Agriculture)) --University of Limpopo, 2015<br>The ability to utilise dietary components differs between fish species. Digestive enzymes may be used to determine the efficiency of the digestive process. In this study, the activities of the digestive enzymes in Tilapia rendalli, Oreochromis mossambicus and Clarias gariepinus were explored. Protease, amylase, lipase and cellulase activities were measured in different parts of the digestive tract of the three fish species. The pH dynamics along the digestive tract were monitored. In all fish species, the presence of food led to a r

This thesis reports on investigations into the influence of diet and a bentonite feed additive on blood parameters in the horse, and the effect of a bentonite feed additive on the process of digestion in the dog. In addition, the methodology of scientific research is examined, and reflections of learning experiences arising from contact with the Hawkesbury approach described. A high-concentrate low-roughage diet, consisting by weight of 70% oats and 30% lucerne chaff, when fed to horses was shown to influence blood red cell levels and blood L-lactate levels compared to three diets of equivalen
