Proteins are essential constituents of animal feeds, which comprise mainly vegetable protein (e.g., soybean meal), which is produced and transported globally. The decoupling of protein-production and livestock-growth areas results in protein deficiencies in certain parts of the world, and in significant environmental stress. Alternative, more sustainable protein feeds are necessary to meet the increasing needs, and to decrease the environmental footprint of animal products. Yeast Single Cell Proteins (SCP), produced locally using various agro-industrial by-product streams, have significant potential as alternative animal feed protein. Particularly, Yarrowia lipolytica, an oleaginous, non-pathogenic microorganism has been characterized as a “workhorse” in biotechnological studies, drawing the attention of many researchers. The present review summarizes available resources on critical issues concerning the applicability and commercialization of Yarrowia lipolytica as an environment-friendly protein source for animal feed. It discusses the sustainability of the yeast SCP production process, it presents the recent advances concerning Yarrowia lipolytica cultivation on low-cost agro-industrial by-products, and it stresses the effects on the health and welfare of productive animals due to the inclusion of Yarrowia lipolytica in their diet. The data presented in this study should facilitate relative research advancement and the commercialization of Yarrowia lipolytica’s use as an alternative protein source/supplement for animal feeds.

Abstract The increasing trend future consumption of animal products will give rise to a huge demand of animal feed. Meeting this demand will be a challenge, given the scarcity of natural resources such as land and water. Currently approximately 1.3 billion tonnes of food is lost and wasted annually, and fruit and vegetables (FV) form a substantial part of this loss. Use of FV loss and waste, as animal feed, can contribute to meeting the feed deficiency existing in most developing countries. Also their use as animal feed will bring them back into the human food chain. Simultaneously it will help mitigating environmental problems that arise due to decomposition of such wastes in the environment. This review, first in a series, discusses options and challenges in using fruit wastes and by-products as animal feed. The fruits discussed are amla, apple, apricot, banana, citrus and raspberry, among many others. The nutritional value, conservation methods, feeding management and guidance on the levels at which these unconventional feed resources can be used in the diets of farm animal species are presented. Some of the major constraints in the use of fruit wastes and by-products are the presence of pesticides, pesticide residues, mycotoxins, heavy metals, furans and dioxins. There is a need to regularly monitor such contaminants in these feed resources. Equally important is to conduct risk assessment given the presence of these contaminants in the animal diets. A concerted research and commercial efforts are needed to realize the full potential of such wastes and by-products for the animal agriculture.

Sugar alcohols and organic acids that derive from the metabolism of certain microorganisms have a panoply of applications in agro-food, chemical and pharmaceutical industries. The main challenge in their production is to reach a productivity threshold that allow the process to be profitable. This relies on the construction of efficient cell factories by metabolic engineering and on the development of low-cost production processes by using industrial wastes or cheap and widely available raw materials as feedstock. The non-conventional yeast Yarrowia lipolytica has emerged recently as a potential producer of such metabolites owing its low nutritive requirements, its ability to grow at high cell densities in a bioreactor and ease of genome edition. This review will focus on current knowledge on the synthesis of the most important sugar alcohols and organic acids in Y. lipolytica.

The idea that associated agro-industrial by-products only with the production of animal feed has been gradually being replaced, as the scientific community is interested in these products, as low-cost nutrients for the composition of food and/or culture media in research biotechnological to increase or improve nutrients or characteristics inherent in the raw material. Thus, this work aims to characterize input for baking with claim of natural fortification from the fermentation by Saccharomyces cerevisiae. For this, biomass was characterized in terms of its composition (ashes, fibers, lipids, proteins, and carbohydrates) and antioxidant activity of phenolic compounds. The results show an increase in nutrients such as ash, proteins and fibers, in addition the free and bound phenolic compounds present in the biomass showed antioxidant potential. Therefore, fermented rice bran is a potential input to be used in baking.

<em>The study was conducted in Urban Community of Niamey at modern and semi-modern farms provided an overview use of agro-industrial by-products in animal feed. Among 57 farms only 17 farms, including 10 beef farms, 2 sheep farms and 5 poultry farms were systematically surveyed. All farm managers are men. 60 and 33% are respectively officials at the level of poultry farms and ruminant farms. Farmers make up 25%, all of which own beef farms. There is also a predominance of adults, 60% at poultry level and 58.33% at ruminant farms. We note the use of a variety of agro-industrial by-products in animal feeds, in this case by-products derived from vegetable processing (wheat bran, exfoliated cotton cake) and animal processing (fish and fish meal ...). There are also some concentrates for poultry feed. Agribusiness by-products are increasingly used in urban livestock production but their valorization needs to be improved.</em>

Brewer?s spent grain is the major by-product in beer production. It is produced in large quantities (20 kg per 100 liters of produced beer) throughout the year at a low cost or no cost, and due to its high protein and carbohydrates content it can be used as a raw material in biotechnology. Biotechnological processes based on renewable agro-industrial by-products have ecological (zero CO2 emission, eco-friendly by-products) and economical (cheap raw materials and reduction of storage costs) advantages. The use of brewer?s spent grain is still limited, being basically used as animal feed. Researchers are trying to improve the application of brewer?s spent grain by finding alternative uses apart from the current general use as an animal feed. Its possible applications are in human nutrition, as a raw material in biotechnology, energy production, charcoal production, paper manufacture, as a brick component, and adsorbent. In biotechnology brewer?s spent grain could be used as a substrate for cultivation of microorganisms and enzyme production, additive of yeast carrier in beer fermentation, raw material in production of lactic acid, bioethanol, biogas, phenolic acids, xylitol, and pullulan. Some possible applications for brewer?s spent grain are described in this article including pre-treatment conditions (different procedures for polysaccharides, hemicelluloses, and cellulose hydrolysis), working microorganisms, fermentation parameters and obtained yields. The chemical composition of brewer?s spent grain varies according to barley variety, harvesting time, malting and mashing conditions, and a quality and type of unmalted raw material used in beer production. Brewer?s spent grain is lignocellulosic material rich in protein and fibre, which account for approximately 20 and 70% of its composition, respectively.

There is an increasing demand for protein rich materials in the animal feed industry in South Africa. Intensive cattle husbandry as well as abattoirs are producing large quantities of organic waste, the protein content of which is not utilized. The compost worm, Eisenia fetida, can be reared in large numbers on this waste. This opens up the possibility to recover waste protein if E. fetida could be used as a protein source in animal feeds. The value of the protein was therefore researched by determining the general chemical composition and amino acid composition. The earthworm meal contained all the essential amino acids required in poultry feeds, in favourable ratios. The methionine and lysine availability was higher than that of fish meal.

In this study, nutritional components that are obtained during poultry slaughtering having significance with respect to processing into animal feeds were investigated. By-products obtained during poultry slaughtering are considered very valuable raw materials for production of highly valuable animal feeds and energetic feeds. Recognition of chemical and physical characteristics of the raw materials represents essential prerequisite for conduction of any technological process, for proper raw materials handling as well as for the equipment and machines design that are necessary for acceptance and processing of the inedible slaughterhouse by-products. Authors have found that the nitrogen complex of the examined raw materials contains predominantly proteins. Digestible nitrogen for all investigated raw materials equals approximately with total nitrogen content, indicating that all proteins from these raw materials are accessible for utilization in animal organism, with exception of feathers that need special technological processing. Basic chemical composition, nitrogen fractions and amino acid composition of the inedible by-products from poultry slaughterhouses indicate that the processing of these raw materials could be directed into production of swine and pet feeds production, as well in production of bio fuels and biogas. Blood and feathers anyhow represent significant protein source, and soft wastes, heads and legs, as well as the mixed raw material, besides as protein source, can be regarded as raw fat source. .
