Till-Hill":ivj4e0aa said:I don't see the 3rd cross being "terminal" in my herd. When crossbreeding you have to use lines that complement eachother......I started with a good angus base. Used polled hereford bulls and on them F1's I put a simmental on them. I am hoping I can say they will be my best cows but my first one is due today. On her I used a herf/angus/tarantaise Pharo composite bull to end up with about a 25% of each breed calf and she is carrying a heifer.
On that calf I would plan on using a simangus bull and breeding the herf and tarantaise out of her.
We are talking small numbers with my herd but in 6-7 years of my fall cows and 50-60 head of calves I have yet to have a PB calf out weigh a x-bred one @ weaning time.
You started off with a great system. Your 3rd cross doesn't have to be a non-keeper, & that 1/4 Herf, 1/4 Ang, 1/2 Simm cow can be a highly productive brood cow. However, if your cow is that crossed up already, putting a super crossed up Bull on them (like the Pharo) is only going to create breed mud. I don't think many would use a bull that crossed up, because most folks want some rhyme or reason (good consistency) in their crossing programs. Often times there is an end, unless you stick to a true 2 or 3 breed rotation using bulls with decent maternal traits. In your case, going back to Angus (instead of the CB Pharo) would make a nice rotation. By choosing 3 breeds (that fit the bill and compliment each other) and sticking to them, you can have a nice orderly program.
Doc reiterates a good point about selecting quality within the individual breeds and the importance of breed complimentation in crossbreeding systems... and what fits one person's system may not fit anothers (both based on environment/resources and ultimate market goals).
