Female Jack vs Male Jack fights

I have a female Jack who is 6 yrs old and my male Jack is approx 8 mos old. They have just mated and now seem to have a love/hate relationship! They go at each others throats and the only way I can make them stop is to grab the tail of the male and pull them off each other. These are vicious fights and I am afraid that they are going to hurt each other very badly! This occurs when they are together and sometimes 3 times a day. There is no rhyme or reason to their fights and I am not sure how to deal with this, aside from keeping them totally apart. They have gotten along fine before this. Any ideas??
