Description
Gut gene switches governing phosphorus uptake differ sharply between two hen strains, Yosef A Abitew's mapping team shows in 2026. The small intestine lining is the main site where hens absorb phosphorus. Gene control there may reveal key drivers of phosphorus balance in poultry.
A total of 400 hens from two high-yield strains ate feed without added mineral phosphorus. Gene activity in gut lining was paired with genome data for mapping. More than one hundred control spots were found for small RNA genes. A similar count was found for standard protein-coding genes in the study. Strain patterns differed: one strain leaned on local control, the other on distant control. Key mineral genes were among the mapped targets.
