At present, the estrus cycle of bovine is controlled by the insertion of progesteroneembedded silicone bands. The disadvantage of nondegradable polymer inserts is to require for disposal of these bands after their use The study currently focuses on preparation of biodegradable progesteroneincorporated nanofiber for estrus synchronization. Three different concentrations (i.2, 1.9, and 2.5 g) of progesterone-impregnated nanofibers were fabricated using electrospinning. The spun membrane were characterized by scanning electron microscopy.enVeterinary ScienceArticle
