My first comment - overall: They are ALL too big to be thrifty, PROFITABLE modern-day producers. That said, in a class of Terminal profitable brood cows, I place them - - 1 - 3 - 2 - 4.
They are all strong, large, deep-bodied, roomy beef matrons. They should all produce good calves. All have deep hindquarters. None of them are FUNNEL BUTTS! You all know what I think of FUNNEL BUTT cattle! Judging by these particular pictures ONLY, #2 appears smoother overall, has a fine udder with small teats, but I criticize her for lack of spring of rib and a pinched heart girth, which could restrict her capacity for producing large, vigorous calves. She is a little finer-boned than the other three, which is not necessarily a negative trait in itself. I would say that # 2 is the best looking (phenotype), but probably not the best performing or the most profitable - at year's end.
Number 4 has moderately good qualities overall, except her FUNCTIONAL TRAITS lack quality. Her pasterns are weak, her udder suspensory ligament lacks strength, her hocks are weak, and her teats are a little large for a newborn calf to easily get early nutrition, which is critical for colostrum consumption! #1 could be a little longer overall, but has adequate bone, a well supported udder with small, well-placed teats. She should raise a great calf each year, which puts her in the PROFIT catagory!
By the way, BishopCattleCo - in the business of beef cattle appraisal - there is NO COW - or - BULL that is PERFECT!! Just as in analyzing Human Beings, we ALL have our faults. Some can be overlooked - some can't. (or shouldn't be).
