Introduction Feed ingredients and manufacturing are expensive components of integrated poultry production, sometimes reaching 70% of total operational costs. Fortunately, the added costs of manufacturing poultry feed improve feed efficiency and poultry performance. The performance benefits from feeding pelleted diets results in a positive return on investment, making it a common practice in broiler and turkey production. Improving the quality of pellets further enhances poultry...

Introduction The “traditional” approach to food quality and safety management is based on end-product testing. However, end-product testing provides only very limited information about the safety status of a food. The food safety crisis of the 1990s (Listeria, Salmonella, Escherichia coli, Campylobacter, dioxins, antibiotics, acrylamide, etc.) highlighted the failure of this traditional approach. If a dangerous organism is found, it means something; but its absence...

Aflatoxins are fungal metabolites—mainly produced by Aspergillus flavus and Aspergillus parasiticus living in soil—that contaminate crops throughout growth, harvest, storage, transportation, and processing. Aflatoxin B1 is not only the most potent natural carcinogen known, but also the most commonly produced toxic strain. As of 2010, roughly 5 billion people worldwide were estimated to be exposed to high levels of aflatoxins. High consumption levels can result in aflatoxicosis,...

Are Your Feeds Safe? This growing season has been a challenge across the upper Midwest. Whether your crops have been hit with drought or hail the odds are that we are going to see an increase potential for feed contaminants such nitrates or molds which cause mycotoxins. This article focuses on mycotoxins and how to manage them. Mycotoxins: Common Questions What is the difference between molds and mycotoxins? Molds...

Introduction Precision nutrition means diets are formulated as close as possible to requirements while avoiding any deficiency issues. Benefits of precision mineral nutrition can include reduced diet costs, reduced environmental impact, and reduced risk of toxicity. The major problem with precision mineral nutrition is increased risk of deficiency. Deficiency can be manifested as a clinical deficiency (e.g., grass tetany caused by inadequate magnesium), or as numerous subclinical...

1. Introduction Apricot ( Prunus armeniaca ) and Peach ( Prunus persica ) are the most important fruits grown and processed in Egypt. Apricot is primarily grown in Mediterranean nations, while it is also grown in Russia and the United States [1,2]. In addition, peaches are the primary species for a variety of cultivars that are widely grown around the world [3]. Thus, there are sustainable abundance amounts of both apricot and peach kernels worldwide, which are...

Introduction Near record high feed, fuel, and fertilizer prices, and high inflation rates all have put increasing economic burden on beef producers. The increased cost of feeding cattle means that increasing feed efficiency is critical to feedlot production. Historically, feed costs represent about 70% of the total cost of production for feedlot operators and therefore, feed efficiency has 4 x greater economic return when compared to the same improvement in feedlot growth (Gibb and...

Introduction On August 28, 2021, the United States Department of Agriculture (USDA) confirmed that African swine fever virus (ASFV) had been diagnosed in the Dominican Republic (https://www.aphis.usda.gov/aphis/newsroom/news/sa_by_date/sa-2021/asf-confirm). This poses a tremendous threat to the swine industry of the United States (U.S.) given the proximity to the mainland. When ASFV emerged in China, the virus was able to move rapidly and easily throughout the country due to movement...

Introduction Monogastric feeds are reliant on plant-based protein sources, like corn and soybean. However, increasing demands on these plant-based materials for non-food industries, such as biofuels, is also associated with an increase in the price of these feed ingredients, placing an impetus on the demand for these alternative protein sources (Leiber et al., 2017). Emerging areas of monogastric animal nutrition research include the use of insect meal, microalgae, single cell...

Introduction The global population is anticipated to reach around 10 billion people by 2050. At the same time the global middle-class is growing significantly particularly in high populous countries such as China and India. The combination of these two factors places significant pressure on global food systems which must be capable of providing food and nutrition security in 2050. The next 30 years are arguably one of the most critical transitions in human history as we approach a...

Introduction In Canada, barley is rarely fed to young pigs due to its relatively high fibre content that is associated with lower energy and nutrient digestibility (Che et al., 2012). Carbohydrates that are not digested in the small intestine may be fermented in the large intestine, and so provide energy and stimulate gut health (Fouhse et al., 2017). Barley cultivars with increased fermentable carbohydrates may enhance gut health in weaned pigs (Jha et al., 2019). Intestinal...

Basic Role of Feed Formulation Feed formulation is a process by which our knowledge of the nutrition of the animal can be translated into feeding programs which achieve our production objectives. These objectives typically include optimizing growth performance and producing a final carcass that can be converted into safe, healthy and appealing consumer meat products. This must be done in a profitable manner that concurrently contributes to environmental sustainability and animal...

Introduction Ergot alkaloids (EA) are a group of compounds produced primarily by fungi of the Claviceps and Epichloë spp. Ergot infection has traditionally been associated with grasses and rye, however when conditions are favourable, other important cereals such as wheat, barley, triticale and oats can become infected. The fungus prefers cool, moist conditions during the flowering phase of the host plant and there is evidence that the incidence is increasing. For example, in a...

Introduction The link between diet and disease transmission has raised concerns that U.S. herds could become infected with foreign pathogens through contaminated feed and feed ingredients originating from countries with endemic disease and lax sanitation and quality assurance procedures. Experimental data has already demonstrated that some feed ingredients, particularly soy-based products, can support the viability of at least three significant viral pathogens of swine (i.e.,...

Introduction Animal production relies on the supply of nutritious feeds supporting high growth, welfare and health of animals and the production of high-quality products in an environmentally sustainable and profitable manner. With feed cost representing 50 to 80% of the total production cost, feed manufacturers have a very important role in the overall economic viability of animal agriculture enterprises. Animal production involves a complex “nutritional supply...
