[QUOTE="Son of Butch, post: 1326777, member: 14585"] Okay let's take WW vs $W and compare 3 proven sires from Select Sires as an example Comrade ... ce 17 bw -3.4 acc .91 [b]ww 52[/b] radg .20 Milk 23 [b]$W 65[/b] Total........ ce -4 bw +3.2 acc .98 [b]ww 66[/b] radg .28 milk 23 [b]$W 45[/b] Early Bird.. ce 15 bw -0.2 acc .75 [b]ww 53[/b] radg .20 milk 23 [b]$W 45[/b] breed ave ce 6 bw 1.3 [b]ww 50[/b] radg .20 milk 24 [b]$W 45[/b] Comrade calves have the lowest ww lbs yet he has the highest $W value out of all 3 bulls How is that possible? Calf Vigor is my theory.... That Comrade calves have a higher survivability to weaning than the other 2 sires Comrade and Early Bird have near identical numbers - E.B. has the 1 lb ww advantage yet Comrade is $20 higher $W Total has the highest WW but is no better than the calving ease bull Early Bird for $W even with a 13 lb higher ww. Why? Bcs Total's calving ease is 10 points below breed average his calves probably have a higher death rate at birth. And it takes a heck of a lot of extra lbs weaned to make up for the value of even one dead calf. The Holstein Association reports calf mortality. But not one beef breed association does, which is strange because IMO calf survivabilty is the #1 factor in beef cow profitability. (One live calf is worth more than 100 dead calves) ww/$W ratios = Comrade 1.25 Early Bird .85 Total .68 That's how and why I use $W vs ww in sire selection. By the way 7AN340 Summit has a fantastic ratio of 1.86 with ww 59 $W 110 [/QUOTE]
