In this episode of Let's Squawk About It, Frank Ivey (Feed2Gain, LLC) talks to Andy Vance (PSA Executive Director) about a type of model used to determine matrix values, and how this model helps understand the impacts of feed changes before they are implemented....

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;...

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...

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...

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...

Protein quality of the soybean meal is the result of amino acid present in the meal and the portion in the bioavailable form to the animals. While intending to utilize the same for monogastric animals, it has to be properly heat processed so as to minimize the anti nutritional effect and thereby increasing the digestibility of amino acids present in the meal. At the same time as known to everyone, it should not be over processed which will decrease the concentration and digestibility of...

In scientific publications in the 1980s – 1990s you can find information about a spreading of mycotoxins. But since that time cultivars and agricultural technology have changed, methods of grain storage and grain processing have improved due to the overal progress. Between January 2009 and December 2011 Austrian researchers selected 7049 samples of grain on different continents. The samples were analyzed for the occurrence of aflatoxins (AFB), zearalenone (ZEN), deoxynivalenol (DON),...

Introduction Academia and industry have invested huge resources into defining both the nutrient composition of feedstuffs and nutrient requirements of meat and egg-type poultry. Both aspects are highly complex because of their dynamic nature. Nutrient availabilities depend on the genetics of each feedstuff, but also geographic region, weather, and growing conditions. These factors impact both the quantity of nutrients and the molecular structures from which those nutrients must...

Introduction Medicinal plants are a rich source of phytochemicals and natural compounds (alkaloids, flavonoids, steroids, terpenoids, tannins and phenols) with marked therapeutic properties (Ruchika et al ., 2022; Roma-Marzio et al ., 2017). They are potential source of drugs and are traditionally used in the treatment of digestive disorders, measles, cold, cough, diarrhea, arthritis, skin disease, joint pain, hemorrhoids, fever, sore throat and sexually...

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...
