Methionine Level in the Diet for Pregnant Female Rabbits Affects Hair Follicle Development of Baby Rabbits

This study investigated the impact of dietary methionine levels in pregnant female rabbits on the hair follicle development of their offspring. Fifty-four Angora rabbits were divided into three groups, each receiving diets with 0.51%, 0.71%, and 0.91% methionine. Results indicated that higher methionine levels tended to increase hair follicle density and diameter at various developmental stages, with significant improvements in fine hair diameter at 2 months in the 0.91% group. The ratio of secondary to primary follicles also increased with development, and primary follicle diameter growth rates were slightly higher in the 0.91% group. Overall, increased methionine levels in the maternal diet stimulated hair follicle development and improved hair fiber diameter in baby rabbits.
