Feed accounts for more than 65% of poultry production costs; thus, accurate feed formulation is vital to ensure poultry are receiving an optimal diet and nutrients are not in under- or oversupply. However, this is difficult when the nutrient specifications of feed ingredients are highly variable. In order to help reduce this variability, appropriate sampling methodology is critical. Nevertheless, recommended methodology and depth of detail within technical articles varies greatly and does...
1 INTRODUCTION North America currently imports plant-based feed ingredients, such as soybean meal, from countries that are endemically infected with viruses of economic and pathologic significance to swine including porcine epidemic diarrhoea virus (PEDV), Seneca virus A (SVA), porcine reproductive and respiratory syndrome virus (PRRSV), classical swine fever virus, pseudorabies virus, foot and mouth disease virus (FMDV) and African swine fever virus (ASFV; Blomme et al., 2022;...
Overview Corn is the most common feed ingredient used in poultry nutrition. Maize contributes with up to 65% of the metabolizable energy and 20% of crude protein in poultry diets (Gehring et al., 2013; Dei, 2017). Its average nutritional value is well-known, but it is accepted that the variability in its composition and energy value is a very common issue with great impact on poultry performance and health (Cowieson, 2005; Gehring et al., 2013; Latham et al., 2016;...
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...
Q: Can you tell us how you arrived at the proposed optimal ratios and amounts of true digestible AAs in diets that you have developed in your research? A: Results of studies by my group have established the concept that animals have dietary requirements for not only...
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...
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 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 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...
Introduction The greater availability of accurate information about products and production systems of various kinds is increasingly changing many aspects of the world economy from a ‘push economy’ to a ‘pull economy’. While producers of food and other goods purchased by consumers formerly determined methods of production, consumers are now exerting more control on production methods (Broom 2014, 2017a). 40-50 years ago, many consumers stopped buying some...

Introduction: Mycotoxins are a large family of toxic fungal metabolites which occur worldwide in various cereals and other feed commodities. During the whole chain from field to feeding, mycotoxins can be produced by molds in plant material. There are numerous mycotoxins which are very toxic to farm animals and may cause different diseases. Therefore they are responsible for reducing animal production. Materials and Methods: To test the occurrence of multiple...
