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;...

Raw Materials Traditionally the most popular raw material for production of textured vegetable proteins in an extrusion system has been slightly toasted defatted soy flour. This defatted soy flour usually meets the following characteristics: 50% protein minimum, 3.5% fiber maximum, 1.5% fat maximum and PDI of 60 to 70. Soy flour with these specifications allows controllable production...

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 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 animal feed manufacturing industry’s main purpose is to recombine different flows of nutrients into safe, nutritious, attractive and handleable feeds which are efficiently converted in animal-sourced food products (meat, eggs, milk). The raw materials harboring these nutrients vary greatly in composition and origin. Raw materials may be co-products sourced more locally from food or biofuel industries whereas others may travel large distances on the globe,...

An experiment was conducted to determine the effects of corn particle size (CPS) on turkey hen performance, intestinal permeability (IP), and litter dry matter. Hybrid turkey hens were housed in floor pens from 0 to 42d. Hens were fed a crumbled starter 1 (0 to 21d) and pelleted starter 2 (22 to 42d) diet. The experiment was a 2 x 2 factorial with diet phase (starter 1 and starter 2) and CPS (fine or coarse), resulting in 4 treatments of 18 replicates of 22 turkeys. Corn was manufactured...

Introduction: More than 80% of slaughter pigs in England show epithelial changes at the Pars nonglandularis (PN) of the gastric mucosa. In the interest of animal welfare and to avoid prospective cost deductions, alternative pig feeding strategies must be developed. In this study the effects of a 2-stage coarsely ground compound feed (COF) on performance and stomach health of piglets were tested as compared to a conventional 1-stage produced COF. Materials and...

Introduction: The castration of male piglets without anesthesia is under public pressure and is already forbidden in some countries. The fattening of boars is an alternative but due to the accumulation of androstenone (A) and skatole (S) in the fatty tissue, resulting in the so called boar taint, some carcasses may be condemned and therefore excluded from human consumption. Skatole is a product of the microbial tryptophan degradation in the hindgut, which can be lowered by feeding raw...
