I think this is simply yet another issue of the show ring chasing extremes.
Personally I believe that a female with some extension and length through her front end is likely to be more feminine, fertile and higher performing.
As a generalisation I believe that cattle with less waste through their front end generally have less waste through the rest of their body. Likewise, cattle that have more length of spine from their withers forward will likely have more length of spine from their withers rearward. These are important traits in my mind.
However, I would totally agree that many cattle are selected in the show ring that are too "frail" in the structure of the front third of their bodies to a point where they lack true depth and capacity through their chest floor and into their rib cage. This to me is one of the most important areas on a beast that needs capacity and one of the key indicators as to the longevity, thriftiness and usefulness of a bovine.
To me, this is an important trait in both bulls and females, I chuckle to myself when I hear people selecting a particular trait in one sex but not another. If you expect your females to have some extension and length in their front end, some length about their skull etc how do you expect to achieve that by using bulls that are shorter through their front third and shorter from their poll to their muzzle and use the belief that this is somehow more "masculine". I see no difference in this example then using lighter muscled, shallow made bulls and expecting to get good stout calves out of them.
Right away I can hear people about to say, "yes but females need to have different traits then bulls".
Sort of, what is important to me is that both examples show SEX CHARACTER.
Furthermore I also believe that it is possible to breed cattle that do have some extension through their front end, that don't have a great deal of excess waste, "leather" or brisket, that can be cleaner through their throat latch and jaw but still have some fleshing ability and usefulness.
In order to achieve this I think we need to stay away from "single trait selection" and use cattle that have a balance of desirable traits.
When I think back to cattle that were bred 10 - 15 years ago when the push seemed to really come to make cattle and particularly British cattle, heavier muscled and "stouter", everybody cried that by doing so we would breed the fertility out of the cattle, they wouldn't milk and we would "ruin the breed" I don't think that has happened, at least not on the whole. I think we are seeing a movement to cattle that are easier fleshing then what we bred 15 years ago, that have comparable birth weights and calving ease and maintain a great deal of performance and usefulness.
Rather than selecting cattle that are "freaky fronted" which to me implies that they have an unusual absence of flesh in their front third (flesh being a combination of fat and muscle) after all if the beast lacks muscle and mass in it's front third is it not fair to expect that it will lack the same in other areas of it's body? I think we can still select cattle that have some length through their front end, that are free from "excessive" waste, meaning they lack both "excessive" hide and fat and still maintain adequate fleshing ability and performance.
To do this I think it's important to select cattle that have good depth of body, which to me means looking from the point of an animals withers to the point of an animals sternum. The longer that line the more capacity they will have through their heart, lungs and vital organs. Likewise they should have width through their chest floor and into their fore rib. It's also important to me that their should be some angle from the point of their withers to the point of their sternum, this will correlate to the angle of their shoulder and their "balance" and freedom of movement. Most times if their is a desirable angle through this area cattle will maintain that balance and likewise have a desirable angle through their hindquarter and rear leg set as this relationship is an indicator of how their spine hooks into the rest of their body.
Sorry to be long winded, just a few observations made in my short life.
Take it with a grain of salt.
