Could anyone let me know about in breeding? If we are desiring to keep heifers for breeding purposes, can they breed with their "father"? If so, can the third, fourth, generation etc stay with the same bull. I have received conflicting information. I have one cow who just recently lost her second calf. It was about 3 months old, nursed regularly, appeared healthy, and I found her dead. I have 10-15 other small animals and this is the only one that would be third generation. Bull is sire of cow.
