The "chicken ribs" of food may have a taste.

People in the process of eating chicken found that the rapid growth of
numil chicken
pectoral muscle appeared "woody" problem, so that
child breast
become dry and woody. This is known as woody chicken breast syndrome.
chicken becomes hard and hard to chew, it will lose the market for broilers and cause significant economic losses to farmers.
U.
is currently the world's largest producer of broiler chicken, conservatively estimated that the disease costs up to $200 million a year. In Delaware, there are more than 700 producers of farmed broilers. Some farmers have found that up to half of chickens have woody chicken breast syndrome.
as one of the important sources of dietary protein, global chicken consumption has increased in recent years, and woody chicken breast has become a worldwide concern.
Researchers at the University of Delaware analyzed the
gene
associated with woody chicken breast, identified the associated
life
markers, and identified unique
biochemical
characteristics of the hard pectoral muscle tissue of sick broilers. Based on these efforts, they finally found the root cause of the woody chicken breast. The findings were published in Scientific Reports.
" abnormal gene expression at the onset of woody chicken breast indicates that the disease is a metabolic disorder characterized by abnormal accumulation of fat in breast muscle tissue. Behnam Abasht, an associate professor of animal and food sciences at the University of Delaware who led the study, said.
the study, researchers noted that broiler chickens with woody chicken breast syndrome had a key enzyme abnormality - higher expression of lipoprotein lipase. This is an enzyme that is essential for fat metabolism and controls how much fat can be in a particular tissue. As a result, this high amount of enzyme expression can cause fat abnormally concentrated in the pectoral muscle.
team used RNA sequencing to determine which genes were expressed in fast-growing modern broiler chickens and slow-growing traditional chickens, and then used a new technique called RNA in-place hybridization to pinpoint where genes are expressed, finding genetic evidence of lipoprotein lipase expression in chicken endotrin cells. Endoblast cells are present in all blood vessels and are the barrier between blood and surrounding tissues.
Abasht speculates that when more fat is oxidized in the tissues of the chicken's pectoral muscle, it may lead to the release of large amounts of free fundamental molecules. Free-molecules destroy fat and proteins in muscles, prompting the chicken's immune system to function.
"We observed that if a particular vein is attacked by an immune cell, it usually also expresses higher levels of lipoprotein lipase." He said.
This discovery could provide potential markers for the identification of sick broilers and help promote short-term solutions that allow farmers to control the condition of chickens at the production level through feed additives or supplements, helping broilers avoid or improve woody chicken breasts.
the problem of woody chicken breasts has only been found in broiler chicken, and scientists don't yet know if the turkeys at the Thanksgiving table have been affected in the same way.
, the researchers also reported common characteristics between woody chicken breast syndrome and complications of diabetes in humans. That said, the study could also provide information for human health studies related to metabolic syndromes, such as diabetes and atherosclerosis, which are associated with fat deposits in arteries.
Abbasht said that if they could find a common solution, a far-reaching goal of the work could be to model chickens and study possible treatments for diabetes in humans.
focus is on solving this problem from an agricultural perspective, but the results also open up new horizons for future research that will benefit both agriculture and human health. This is a very interesting prospect for us. Abasht said.
