This article explores the alarming link between swine manure management practices — specifically pit/lagoon agitation and emptying — and the occurrence of Porcine Reproductive and Respiratory Syndrome (PRRS) outbreaks.
The study, conducted between July 2019 and June 2020 and collecting data from 150 affected sow farms, demonstrates a definitive temporal relationship between these practices and the probability of reporting a PRRS outbreak. Authors Carles Vilalta,...

Respiratory diseases hurt swine operations on both the input and output side of the equation: feed costs rise as performance plummets. New research suggests that by using soybean meal, you can mitigate these challenges as a cost-effective tool for maintaining pig health and performance during outbreaks. Respiratory Diseases Present Challenges When pigs are infected with respiratory diseases such as swine respiratory disease (SRD) and porcine...

Growth of the modern broiler is very adaptable to a vast range of diet nutrient densities, and so formulation matrices are greatly impacted by prevailing economic situations. The broiler still eats quite precisely to its energy needs and alters its feed intake in response to variable diet energy level. For example, 25-35d broilers can be fed diets a low as 2850 kcal/kg or as high as 3500 kcal/kg as seen in some locations, and growth rate is little impacted if the bird can adjust its feed...

1. Introduction Reducing the particle size of cereal grains increases the digestibility of starch and energy by pigs (Huang et al., 2015; Rojas and Stein, 2015; Lee et al., 2024) and it is likely that surface area of grain particles and interactions between particles and digestive enzymes are increased by reducing particle sizes. In contrast to the demonstrated improvement in the digestibility of starch and energy, effects of particle size reduction on digestibility of amino...

This analysis is based on the book chapter "Relevant fungal species and associated mycotoxins in storage," authored by Carla Cervini, Andrea Patriarca, Carol Verheecke-Vaessen, and Angel Medina, published in Mycotoxins , DOI: 10.1163/9789004724969_011.
While pre-harvest contamination receives significant attention, storage is identified as the most critical stage in the food supply chain where fungal growth and mycotoxin accumulation can severely impact food and feed safety....

The use of feed enzymes in monogastric nutrition has been a cornerstone of feed efficiency and environmental management for decades. However, a recent analysis suggests that the industry's long-held "scientific dogma" may be limiting the full potential of these additives. In an article on AB Vista's website titled "Enzymes through the ages: rethinking their use in animal nutrition," Mike Bedford (AB Vista) argues that the industry's focus on simple, measurable outcomes has created a...

INTRODUCTION Due to its nutritional value, corn (Zea mays L.) is one of the main ingredients used in the diets for poultry worldwide. Brazil is one of the largest corn producer and exporter countries (USDA, 2021), and, according to ABIMILHO (2023), about 50% of the corn produced in Brazil in the 2019/2020 harvest was used for animal consumption, reaching more than 54% in the 2022/2023 harvest. The grain is globally traded as a commodity because it is a homogeneous product from which...

Extreme rains in northwest Iowa have caused instances of stored grain being covered with floodwater. According to current Food and Drug Administration policy, grain inundated by uncontrolled river or stream water is considered adulterated and must be destroyed. The current situation is one of river water flooding rather than of rain-driven pooled water in low ground, for which there are salvage options. River-based floodwaters can bring in many hazards and rapid spoilage. Flooding...

I. INTRODUCTION The laying hen has a considerable requirement for dietary calcium (Ca) and phosphorus (P) to support optimum egg production, egg quality and other physiological processes. In particular, a high intake of Ca ranging from 4 to 4.5% of the diet is considered important as the laying cycle progresses from early to late lay to achieve optimum egg number and egg shell quality. A capacity for birds to increase Ca intake from a separate Ca source as dietary Ca levels diminish...

I. INTRODUCTION Necrotic enteritis (NE) is of great concern to the poultry industry due to its deteriorating impact on production and increasing mortality, resulting in a US$6 billion global economic loss (Wade and Keyburn, 2015). The causative agent of NE is Clostridium perfringens, a gram-positive spore-forming anaerobic bacterium. The subclinical form of NE is financially more devastating than the clinical form. This is due to a lack of obvious symptoms resulting in a delayed...

I. INTRODUCTION Microbial enzymes are now routinely used in broiler chicken diets to reduce the effects of antinutritive factors (ANF) in feed and/or improve the digestion of nutrients (Bedford, 2011). There is a suite of enzymes that target ANF such as non-starch polysaccharides (NSP) and phytic acid as well as products which improve the digestion of nutrients such as protein and minerals. The major cereals used in poultry diets are wheat, maize, sorghum and barley. The objective of...

In the world of animal feed manufacturing, some parameters shout: protein levels, energy values, additive profiles. Others whisper, quietly shaping performance from behind the scenes. Particle size is one of those silent drivers. And yet, for monogastric species like pigs and poultry, it can be the difference between optimal feed conversion and costly inefficiencies. I’ve spent over three decades in feed process technology, and if there’s one...
