Providing chicks a dark period from the time of placement in the broiler house is practical and affordable for broiler producers and has no apparent negative effects on broiler performance, according to research conducted by Garret Ashabranner, PhD; Brian Fairchild, PhD; and Michael Czarick, engineer at the University of Georgia.
During cold weather, an objective of an environmental control system is to bring in small amounts of cold, fresh air uniformly throughout a house to maintain good air quality without chilling the birds or resulting in excessive heating costs. The primary method of obtaining this objective is using a negative-pressure ventilation system.

Day-old birds immunized with vaccines for Georgia (GA) and Massachusetts (Mass) serotypes of infectious bronchitis virus (IBV) were shown to be protected against four other circulating IBV variants in a recent study.
Innate and adaptive immunity in poultry against coccidiosis is complex, involving activity from many cells and molecules. Fortunately, research is shedding light on potential routes forward to help birds fight the ubiquitous parasitic disease.
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.
Human-animal interaction is the mutual and dynamic relationship between a human and an animal where the animal perceives human interaction as degree of relatedness or distance and vice-versa. Human beings have domesticated poultry species for eggs and meat production. However, fearfulness as a trait still persists and domestic animals often perceive human encounters as fearful.
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.
With the recent rise in the use of slow-growing lines for pasture-based and free-range broiler production, worm infestations could become a significant issue. Warmer weather also contributes to the rise in worm populations, as moisture and humidity create favorable conditions for parasite eggs to thrive, explains Prafulla Regmi, PhD, University of Georgia.
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.
Varying periods of light and dark can affect turkeys’ health and well-being, including their eye health, level of fearfulness and mortality, according to a study led by Allison Pullin, PhD, animal welfare professor at North Carolina State University.
