July 2025 in “Food Science & Nutrition” This study found that vitamin D supplementation in diets of Rex rabbits improved hair follicle development and fatty acid metabolism, with 1400–2100 IU/kg proving most effective for hair density and 2800 IU/kg increasing hair length.
January 2014 in “Dongwu yingyang xuebao” The study concluded that a dietary vitamin A level of 10,000 IU/kg optimally supports growth performance, fur quality, and antioxidant function in growing Rex rabbits.

October 2021 in “Animal nutrition” This study found that dietary pyridoxine increased hair follicle density in Rex rabbits by activating PI3K/Akt, Wnt, and Notch signaling pathways, which may promote hair growth and delay telogen onset.
August 2025 in “Animal nutrition” This study found that supplementing with 1.5% α-ketoglutaric acid significantly improved the performance, hair follicle density, and antioxidant capacity in Rex rabbits, potentially by enhancing the Wnt signaling pathway and reducing amino acid catabolism.
