Introduction Fusarium graminearum is a globally important pathogen causing Fusarium head blight (FHB), a devastating disease of cereals worldwide which can be caused by several Fusarium spp. The pathogen has biotrophic and necrotrophic (saprophytic) growth phases [1] that require adaptation to different environments like soils, plant debris, and living plants. The fungus is responsible for yield losses and contamination of the grains with mycotoxins; mainly deoxynivalenol (DON)...

Introduction In the recent years, the European legislation aimed to strongly reduce the impact of agricultural practices on environment and on health and wellness of operators and consumers. Community new Directives and Regulations, gradually implemented by specific Legislative Decrees at national level, imposed the revision of all criteria and rules for the production, market and use of active substances and products for plant protection in the European Union. This led to a...

Yeasts are single-celled, facultative anaerobic eukaryotes that are prevalent in various fermented feeds. Yeasts can negatively affect silage quality by metabolizing available nutrients within the feed which leads to dry matter loss and decreased nutritive value, and by producing ethanol which can lead to off flavors in milk when consumed. Yeasts also oxidize lactic acid, which increases silage pH and promotes the growth of organisms such as mycotoxin-producing molds. Although wild yeasts...

Introduction Fusarium head blight (FHB) is a global disease of wheat (Triticum aestivum L.), causing severe epidemics in Brazil, the USA, Canada, China and Europe over recent years [1]. FHB is caused by the Fusarium species of hemibiotrophic fungi, with F. graminearum being the most prevalent worldwide [2]. In wheat, the characteristic symptom of FHB is the bleaching of infected spikelets prior to senescence [3]. This bleaching can spread from the...

Introduction Aspergillus is a filamentous fungus that produces mycotoxins (secondary metabolites), the main contaminants of food and cause adverse effects on human and animal health. The consumption of these toxins may lead to immunosuppressive, mutagenic, and carcinogenic diseases [1]. Various species of the genus Aspergillus produce aflatoxins such as Aspergillus flavus, A. parasiticus A. nomius, A. pseudotamarii, A. bombycis, and A. ochraceoroseus [2,...

Introduction Maize ( Zea mays L.) is the most important cereal crop before wheat ( Triticum aestivum L.) and rice ( Oryza sp.) for worldwide production. In Northwestern (NW) Europe, maize cultivation started on a large scale with the upcoming of hybrid cultivars in the 1960s. However, in the 500 years since Columbus’ voyages, a great array of landraces were cultivated in NW Europe which descended mainly from Northern flints introduced from...

1. Introduction Fusarium of the spike is the main disease of cereal plants worldwide. The disease can lead to a significant reduction in yield (up to 30%) and quality in the form of atrophy, weight loss and discoloration. Fusarium also produces mycotoxins, which can adversely affect livestock and human health [1]. Early and rapid detection, monitoring of the development of the disease are the bases for the control of Fusarium and the mycotoxins it produces in seeds. Currently,...

I. INTRODUCTION Wheat is the predominant feed grain in Australia and other dry regions in the world. Typical broiler diets in Australia contain 60-70% wheat. Climate-induced factors, including elevated temperature, have been reported as depressing crop production around the globe during the last few decades (Fernie et al., 2022) and there is limited understanding of how climate-induced factors may influence the nutritional quality of wheat. The sowing time of wheat is the most...

Insects and derived products are possible alternative feedstuffs to improve the sustainability of the livestock sector due to several promising attributes such as limited space requirements for growing larvae, short productive cycles, limited water needs and the suitability of some species to mass rearing. Also, some insect species can contribute to circular economy models by upcycling organic side-streams from other industries into high-value...

I. INTRODUCTION Improved production efficacy in laying hens has been achieved by selecting individual birds that lay longer clutches of eggs (Dunn, 2013; Bain et al., 2016; Preisinger, 2018). In addition, the length of the productive life of hens has been extended to one hundred weeks of age or more. These 'long-life' layers were predicted to produce 500 eggs by 100 weeks of age (Bain et al., 2016; Hy-Line, 2020), and this is now being achieved commercially (Gautron et al.,...

Nelson Ruiz (Nelson Ruiz Nutrition LLC) A set of 24 solvent extracted commercial soybean meal (CSBM) samples, which corresponded to the same lots of CSBM used in the field, were evaluated. The CSBM were from different origins (Argentina, Bolivia, Paraguay, Trinidad & Tobago, U.S.). The objective herein was to evaluate the relationship between KOH protein solubility (KOHPS, a measurement of overprocessing) and trypsin inhibitor activity (TIA, a...

4.1 Introduction The metabolism of most nutrients in domestic dogs and cats is similar to that in other mammals (Baker and Czarnecki-Maulden 1991). Thus, the qualitative dietary requirements of dogs and cats for most nutrients [e.g., amino acids (AAs) that are not formed de novo in animal cells] are similar to those for omnivores (e.g., humans and pigs). However, dogs and cats have a relatively short digestive tract (He et al. 2024) and have evolved to have some unique feeding...

1. Introduction Increased atmospheric emissions of greenhouse gases (GHGs), such as nitrous oxide (N 2 O), carbon dioxide (CO 2 ), and methane (CH 4 ), are the primary cause of climate change. These emissions result in unpredictable and erratic rainfall, floods, and droughts [1]. In 2020, agriculture contributed 5865.47 MtCO 2 e, representing 12.34% of its total emissions (47,513.15 MtCO 2 e), including land-use change and forestry...

Introduction Modern maize, belonging to the genus Zea, was domesticated in southern Mexico 9000 years ago from wild, annual tropical grasses called teosintes, with the primary ancestor being Parviglumis (Zea mays ssp. parviglumis) which survives today in the wild (Matsuoka et al., 2002). There are additional species of teosintes that continue to grow in the wild in Mexico and Central America including the perennial Zea diploperennis (Iltis and Doebley, 1980). Following its...

INTRODUCTION Maize (Zea mays L.) is a staple food in many parts of the world including sub-Saharan Africa (SSA). In Nigeria and some other West African countries, it is traditionally transformed by submerged fermentation to ogi – a complementary weaning food for infants and young children, convenient food for the sick, convalescent and elderly or quick breakfast mostly for those living in rural areas characterized by low income (Onyekwere et al., 1989; Steinkraus,...
