You are twisting words. I did not say YOU are starving your cows. I did not imply you wanted them to starve their cows.
Yes, you can add about 10# of weight on a fetus by feeding too much protein the last 90 days of gestation. No, that 10# does not cause more dystocia worth reducing the quality/amount fed to the cow to avoid the extra weight.
Do I recommend over-feeding a pregnant cow? Absolutely not. But, it has been proven by research, you are better off over-feeding than underfeeding. Especially heifers, should be gaining wight up to parturition.
I firmly believe a heifer should be 6+ BCS, if you expect her to have calved at 24 months and plan to have her calve at 36 months old.
I simply disagreed with your advice. Different opinions. That is why we are replying on an open forum.
I have only been calving for nearly 50 years. Read tons of University & beef reports because I put out a 24 page newsletter 5 times a year. So, I have to be up-to-date with as much info as I can. Merely sharing the knowledge I have acquired. Sure don't know everything and still learning.
