this publication from colorado state contains some good tables on daily gain as it relates to size, sex and energy consumption. some of you might find it helpful in comparing the amount of energy required to achieve the gain desired for a particular size and sex of animal. you don't have to actually use the net energy computations, just realize how much the energy requirements change with size, sex and with the amount of adg desired.

Very good link. Most understand protein to some extent but give very little thought to energy levels in various feeds for cattle in an operation whether for maintenance, gain and/or lactation all of which can effect the bottom line of any operation by way of low body condtion, low conception rates, low weaning weights and/or all of the above. Most feeds purchased in a bag won't have the information available and the man at the feed store won't have a clue what you're talking about but some "at home" study can bring you a working knowledge or call a feed company nutritionist and see if he will give you some general information. It shouldn't be a secret.

It seems these gain tables are specified for implanted cattle only as stated in note 4 of the example just before the tables. Its not clear to me whether the reference to the types of implants is saying these numbers are 10-12% higher than without implants, or that you could get another 10-12% above these "implanted" numbers by using a different type of implant.
