Description of problem
Adding antibiotics in feed as growth promoter and health enhancer has been excluded in many developed countries (Afiouni et al., 2023). In the concern for antibiotic free livestock products, researches on potential feed additives as antibiotic alternatives...
With more eggs in the grocery store coming from hens in cage-free housing — about 40% in early 2024 — commercial egg producers want to know which hens are best adapted to that environment.
To help answer their questions, an...
As already highlighted by more than a decade of scientific research, using insects – mainly Hermetia illucens (HI) and Tenebrio molitor (TM) – as alternative feed ingredients represent a promising and feasible nutrition strategy in poultry production. On the...
A new study shows chicken fertility rates in U.S. broiler eggs could decline to approximately 60% by 2050. That decline could lead to chicken production issues and higher costs for consumers.
The study, “How concerned should we be about broiler...
A new study found that a pair of probiotics fed to broiler chickens successfully persisted in the animals’ digestive tract, making the bacterial species promising candidates to improve poultry health. One of the species used in the experimental freeze-dried...
Description of problem
Newcastle disease (ND) is a highly contagious viral disease that significantly threatens the poultry industry and global economies. It is caused by virulent strains of NDV, which belong to the genus Avulavirus, family Paramyxoviridae, and order Mononegavirales...
Introduction
The poultry production industry is progressively phasing out cage systems (CS) due to increasing concerns regarding animal welfare (Kollenda et al., 2020). The absence of nests in CS is particularly detrimental to welfare (Duncan, 1992), as hens naturally prefer...
As poultry companies weigh cost and efficiency with higher animal welfare standards, research comparing conventional and slow-growing broiler breeds showed that the slow-growing chickens displayed behaviors more closely associated with positive welfare.
Broilers—chickens specifically bred for meat production—are typically raised...
It is expected that the global population will increase to 9.7 billion in 2050 (United Nations, 2024) and the amount of agricultural land per person will drop from 1.4 to around 0.2 hectares per person (United Nations, 2024; Our...
Knowing where, when and for how long mallard ducks – natural carriers of avian influenza – stop and rest as they migrate can help predict the probability that they will spread bird flu to backyard poultry flocks.
The finding, from a Feb. 18...
