The relationship between circulating concentration of anti-mullerian hormone (AMH) and the LH content of follicle stimulating hormone (FSH) preparation on follicular growth and ovulatory response in water buffaloes was evaluated. A single blood sample was taken from cows (N=31; age: 9.06±0.98years) to determine systemic AMH. Animals with concentrations higher or lower than 194±30pg/ml were placed into LOW and HIGH AMH groups and were assigned randomly to be superovulated FSH containing either a high (FSHp, HLH) or low (FolltropinV, LLH) LH content. Follicular growth and ovulation were monitored using transrectal ultrasonography. In animals with HIGH systemic AMH, treatment with FSH with a high LH content was associated with more small follicles (AMH X FSH; P=0.02). AMH had no effect on small follicles in animals treated with LLH. Females with a HIGH AMH had greater numbers of small follicles (P=0.01) and total follicles (P=0.005) than LOW AMH cows. Animals treated with HLH had more small follicles (P=0.001) but fewer large (P
