At the 2024 Poultry Science Association meeting, Molly Lobel, PhD, and her team at the University of Kentucky presented their findings from a study involving feeding mycotoxin-contaminated corn fines to broilers and exposing the birds to heat stress.
Saponins have become an increasingly common additive in poultry diets over the past decade, thanks to their potential to support bird health and reduce emissions, but it’s crucial for producers to carefully select the right saponins to maximize benefits for their flocks.
Research is showing how to effectively adjust amino acid levels in layer pullet diets, maintaining birds’ longevity and egg production without adding cost.
Advanced microbiome analysis using non-lethal sampling and machine learning can guide changes on broiler farms that lead to earlier gut maturation in birds and performance gains, according to research using the technology with multiple flocks.
Black soldier fly is increasingly well-known as a sustainable alternative protein. But frass, a byproduct of producing meal from the insect, could also offer an option for feeding growing broilers.
Exogenous feed enzymes are commonly used in commercial monogastric diets to enhance nutrient and energy digestibility by reducing the impact of antinutritional factors, releasing additional nutrients or both.
Results of a study suggest that peas and pea products could be an attractive alternative to soybean meal as a dietary protein source and provide potential gut-health benefits, such as reduced pathogenic bacteria and increased commensal bacteria.
Is diet the rising X factor for optimizing immunity in poultry? Researchers at the Southern Poultry Research Group (SPRG) in Athens, Georgia, are building a strong case, via a growing body of research shedding new light on how diet influences the traditional pathogen-host-environment triangle for assessing disease risk.
A prebiotic derived from brewer’s yeast (Saccharomyces cerevisiae) has shown potential in reducing the prevalence of Salmonella Enteritidis in broilers.
Finding the right balance of economics and growth performance is key when developing turkey poult diets. Limiting the metabolizable energy content is one way to reduce costs, but that can also reduce the young birds’ growth potential. Lysophospholipid supplementation could be the answer.
Coccidiosis and histomoniasis are ubiquitous problems for poultry producers. Recent studies have suggested that using a blend of plant extracts could help reduce symptoms of infection and improve production outcomes.
