In the highly automated world of poultry production, precision livestock farming (PLF) technology to monitor birds in real time can be used to improve their health, welfare and efficiency. But there are limitations to this technology.
Low crude-protein diets are a well-proven practice to reduce diet cost and minimize excess nitrogen and excreta, thereby benefiting profitability, health and welfare in broilers and swine. However, the laying-hen industry is far behind in understanding the interaction and requirement of lower amino acids.
Calcium plays a key role in poultry feed conversion. In addition to bone density, muscle contraction and other critical functions, calcium affects the efficiency of turning food into weight gain. But in broilers, it’s not just the amount of calcium that matters. What really counts is bioavailability: how much of that nutrient the bird can actually use.
Maintaining indoor air quality is a constant concern for poultry producers. In particular, ammonia levels within houses are a health concern for poultry and workers. But what about the ammonia in exhausted air? Researchers from the University of Georgia are using a novel approach to remove and recover ammonia from large layer-poultry facilities.
Dust particles in poultry houses can exacerbate the spread of highly pathogenic avian influenza (HPAI), with the virus on dust particles remaining infectious for up to 17 hours. By the birds’ activity, it can easily be aerosolized into the environment and, by the ventilation system’s airflow, can be transmitted within the barn and from barn to barn.

Regular monitoring of broiler drinking-water consumption helps track flock health and performance. A sudden dip or downward trend can alert the producer to potentially serious health or production problems.
Producing the best feed for turkey production takes more than choosing a mash or pelleted version. It also includes maintaining quality from processing to the feeder.
Studying genetic material from the air in layer poultry-production facilities has shed new light on potential opportunistic pathogens with antibiotic-resistance genes.
As animal welfare science has evolved, the importance of using animal-based measures to study welfare has become apparent. Birds may have needs and feelings that aren’t immediately obvious to humans, and their priorities are influenced by an evolutionary history that is vastly different than our own.
A precision poultry-feeding system developed by University of Alberta scientists has the potential to bring improved fertility, better flock uniformity and significant savings for broiler breeder producers.
