The U.S. Environmental Protection Agency (EPA) wants to use updated computerized models to guide regulation of air pollution by animal feeding operations, including broiler chicken farms. Live production managers and others are supposed to use these models to determine whether a farm's emissions exceed established limits for five major air pollutants, which would trigger regulatory permitting. Ho ...

The extraction of plant oils from crops results in so-called “waste” products that can be repurposed as protein sources for animal agriculture, supporting the development of a circular economy and the world’s bio-economy sector. In the Mediterranean region (as well as similar climates), the production of olive oil has increased, leading to large quantities of olive oil byproduct ...

by Lyndsey Johnston Insects and derived products are possible alternative feedstuffs to improve the sustainability of the livestock sector due to several promising attributes such as limited space requirements for growing larvae, short productive cycles, limited water needs and the suitability of some species to mass rearing. Also, some insect species can contribute to circular economy models by ...

by Lyndsey Johnston A group of researchers from the Georgia Tech Research Institute, University of Saskatchewan, University of Georgia, Auburn University, USDA-ARS U.S National Poultry Research Center, and Tyson Foods studied the concept of an alternative slaughtering procedure on farm and its effects on carcass quality, carcass microbiology, and meat quality. The team hypothesized that the on-fa ...

As the global poultry industry has grown and developed, a great variety of consumer products has emerged, focused on convenience and practicality, that provide opportunities to regain value from carcass parts that may have otherwise gone to waste. During poultry processing, novel products such as fresh sausages can be an alternative use for compromised meats, such as those affected by deep pector ...

Commercial egg laying operations can benefit from more effective and economical ways to depopulate flocks at the end-of-lay while improving worker performance and maintaining or improving animal welfare. Recent on-farm research in Switzerland applied portable blue light units and specialized crate carts, seeking to improve depopulation during catching, carrying, and crating without changes to floc ...

Dietary alfalfa may improve broiler growth, but fiber inclusion may be detrimental during coccidiosis challenge. Alfalfa is a source of health-promoting bioactive compounds (phytochemicals) that may offer several benefits to the poultry industry by direct action or by influencing the microbial communities in chickens. Iowa State University researchers recently examined the role late-cutting alfa ...
