Zanzibar is my choice now. Long enough, good bones structure on legs. Good shoulders shape. Like him.
Never had much luck keeping an animal in w/ that much length in good condition. Does he have the depth to justify that length?
I am thinking Zanzibar is deep enough. He is one of the most balanced bulls this year. I found last summer that when I was checking pastures and was scanning the herd to see if everything looked healthy. my eyes would stop when I looked at him. He always seemed to be standing exactly right and he has always looked very straight in his lines. His mother is one of the deepest and thickest cows in our herd, and she is very moderate framed. Another thing that always surprises me, is how much Zanzibar weighs. He is not the biggest bull in the pen but he is one of the heaviest. At the rate he is gaining, he could be around 1350 at 12 months. His BW was 92 lbs. What makes me like Zanzibar even more is his full sister ( Dora's natural calf in 2012) is my pick of the heifer calves as well.
Really like your Zanzibar and Zodiac bulls- from the photos they seem to be the really complete type, bulls with performance, stoutness and good structure.
I guess I look at them differently than some, but having had to take physical measurements on hundreds of cattle for a USDA research project, I'm much more interested in length than depth of body. Today it seems there's almost an obsession with how deep an animal is, but people seem to forget that in the bovine, the sternum or base of the chest floor lies between the front legs and extend back, enclosing and protecting the internal organs. Anything that lies below this line (for reference thing about the elbow pocket) is fat. It's not as many claim the sign of greater rumen capacity -- the rumen is inside the rib cage - so extra "deep" cattle don't have the ability to consume more, they just demonstrate an ability to add flesh. That's not necessarily a bad thing, but it's economic value is limited. A more important evaluation would be the rib cage circumference, as this is a better indicator of true capacity.
Length of body or more accurately, length of spine, is directly coordinated with carcass weight and yield, so it does have the potential to impact profitability for those who feed cattle. I'd have to go back and look, but I don't think there is a lot of correlation between depth and length, if memory serves me the correlation is between rib cage circumference and spine length. So you should not have to choose one in favor of the other.
Regardless, if you want deeper cattle because you need to add fleshing ability, you can still have length of body. As in any trait, excesses are not good, but within normal ranges, cattle that are longer spined will typically have greater performance that those that are shorter spined.
