When given metformin, the hens laid extra fertile eggs, had decrease physique fats and confirmed more healthy reproductive hormone ranges than these not given the drug.

This prompt metformin improved the hens’ ovarian perform, stated Ramesh Ramachandran, a professor of reproductive biology within the college’s Faculty of Agricultural Research.

Analysis revealed this yr confirmed the drug “switched on” a number of genes associated to producing yolk protein within the liver and stabilizing blood sugar. It additionally “switched off” genes linked to fats buildup.

“Primarily, metformin helps older hens keep metabolically more healthy, which lets them preserve producing eggs properly past their typical decline,” stated researcher Evelyn Weaver.

By extending egg manufacturing in broiler breeder hens, farmers might not want to switch flocks as typically. This could have effectivity and animal welfare benefits, the researchers stated.

Metformin is shortly metabolized and there’s no threat of it getting into the human meals provide, Weaver stated.
