Hi Everyone
You'v helped me before but i was wondering if you could help me with this? I am coming to the end of my ND in animal management my last breeding and genetics assignment is about reproduction technology. (This is the assignmet brief)
1) define infertility and dystocia and for each describe THREE situations using breed specific examples. 
2) what measures could the breeder take to prevent these problems and how would they be resolved?  

so here's where i need your help....... breed specific infertility and how would the breeder resolve this?
i can use any reason for infertility the three i have chosen are: Congenital..abnormal sexual differentiation. Infection..brucella canine infection. and Hormonal..Hypothyroidism. Could you's maybe suggest any specific breeds that suffer from these problems or any other breed specific  infertility problems? As i dont mind changing the reason for infertility if you's know of any easier to find information on Any help much appreciated thank you all Scarlet
