We had 13 heifers we raised bred by AI. The sire chosen was exceptional. A couple of the bull calves are very good. Could we save them to use in our herd or would inbreeding be a problem?

I live in SE-NEB. and calve starting about April 20th, I was thinking about pushing it back until May 1st. But would that be too late to match my cool season grass? I was going to go to 1st of May so my grass supply would be a little larger then it is in April. Reason I calve "late" now is because of snow storms and cold weather.
