ALL are merely average potential BEEF producers!
Bullet - Good topline, level rump but needs heavier bone and shows weak hindquarters.
Fiona - This heifer is a more beef type heifer than Bullet, but appears cowhocked and needs more bone. She has a good head, and should make a fairly good brood cow if she is bred to a really good BEEF BULL! Better hindquarters than the Bullet cow.
Stardust - Very good "breedy" head showing good beef cattle characteristics. Well defined foreleg. Needs to be deeper through the heart girth, and poor 'Funnel Butt' hindquarters.
Luna - Her head is too large in proportion to her body, although the camera angle may have something to do with that problem, however she needs more bone, has a sloping rump, weak hindquarters, is pinched in the heart girth.
You didn't ask for comments on the sire of these heifers, but I feel compelled to do so anyway! G A Rito F54 is SO weak in the hindquarters and demonstrates an exaggerated FUNNEL BUTT! This is the prime reason for your heifers ALL showing this weak hindquarters trait! Look at him critically and don't be BARN BLIND!
Fireball - Very lacking in the hindquarters and shallow flanked. Cross-breeding with this bull will not benefit you genotypically or genetically.
Cocoa - This is a very bad picture and poor positioning of the bull to be able to analyse his characteristics adequately. His hindquarters are insufficient and inadequate. Funnel Butt!
Diesel is your best BEEF BULL, but needs more spring of rib and a deeper flank. How will he balance the Phenotype and Genotype of your cows?
In order to successfully and CONSISTENTLY breed profit-making Beef Cattle, one must incorporate the very best BULL genetics that is possible, year after year after year! You can lose 15 - 20 years of careful grading-up of your herd by using one generation of an unsatisfactory bull!
I know that you didn't request this critique, but I felt obligated to offer my opinion anyway. Breeding Beef Cattle is a tough business, and you can throw away years of effort and MONEY in an unguarded moment.
