The trend toward reducing or eliminating antimicrobial use in broiler production has led to an increased incidence of necrotic enteritis, resulting in the need for alternative intervention strategies, such as vaccination, to control NE.
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.
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.
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.
Eggshell translucency is linked to several hatching-egg quality parameters but not egg specific gravity or eggshell color, according to a recent study published in Poultry Science.
Traditional methods to detect Salmonella in poultry and trace outbreaks often fail to give the full picture of the threat in enough time for integrators to act. This lack of oversight limits the effectiveness of intervention strategies designed to mitigate Salmonella transmission.
A new vaccine-application approach shows advantages to help make on-farm, day-of-age vaccination easier to perform while increasing effectiveness.
Lighting, among other factors like feeding and ventilation, plays a critical role in the growth and behavior of poultry and should be given careful consideration. Gabrielle House, PhD, ONCE by Signify, discusses the four main factors to consider when selecting which light source is best for your poultry house.
The poultry industry is less resource-intensive than other forms of animal agriculture, yet sustainability practices are crucial within the industry to address environmental concerns, particularly greenhouse gas emissions.
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.
In cage-free systems, it’s not only the birds that are moving around more freely. Bacterial transmission is also quicker and more efficient when birds roam uninhibited in large groups, underlining the importance of effective disease management.
