Preventing disease transmission between flocks is a major goal of the poultry industry. One threat to bird health is the protozoan Histomonas meleagridis, which causes a disease called histomoniasis.

New study shows brain size is smaller in commercially bred laying hens

sspiegel0120@gmail.com on October 20, 2023

When humans domesticate and breed an animal, they tend to select for a very specific trait. In laying hens, artificial selection for high egg production has led to hens that can produce 320 eggs a year. But could artificial selection have unintentionally altered hen brain morphology?

Broiler chicks can be provided between 1 to 4 hours of darkness a day without negative consequences, according to a recent study.

Do minerals and vitamin C affect performance of heat-stressed broilers?

sspiegel0120@gmail.com on August 8, 2023

Researchers from Spain and the Netherlands performed a study to determine if adding a mineral and vitamin mix (AHS and Vitamin C) would have an effect on broiler performance in heat-stressed conditions.

Poultry scientists investigate microbial presence in low, high stocking densities for free-range layers

sspiegel0120@gmail.com on August 1, 2023

As consumer demand for eggs from free-range chickens grows, a big question lingers: what is the best stocking density for chickens in free-range conditions?

Pekin duck research reveals heritability of feeding behaviors
