For beef cattle fattening, should the focus be on daily gain, concentrate feed cost, or daily gain at an appropriate concentrate efficiency?

Since voting is not possible, I am listing the questions here. Crossbred beef cattle fattening is set to start at 200 kg body weight and end at 500-600 kg, for discussion:

1. For high daily gain, how much concentrate is needed to achieve a daily gain of 1.5, 2.0 kg or higher?

2. To lower concentrate cost or reduce the amount of concentrate fed, what measures can be used to maintain a beef cattle daily gain of 0.8-1.0 kg?

3. For an appropriate concentrate efficiency, what should the concentrate-to-weight-gain ratio be, what is the daily gain in kg, how many months is the feeding cycle, and what is the body weight range for beef cattle from start to finish?

The situation with roughage should also be specified!
For example, whether the roughage is dry corn stalks, whole-plant silage, whether there is distillers' grains, etc.

"To lower concentrate cost or reduce the amount of concentrate fed, what measures can be used to maintain a beef cattle daily gain of 0.8-1.0 kg"?
It should be necessary to increase the nutrition of the roughage and improve its digestibility.

The roughage can be set as dry straw or silage straw; whole-plant silage is generally not used for beef cattle because the cost is too high.

As supplementary materials, fresh grain (cereal) distillers' grains, brewer's grains or tofu residue can be used.

From the date this post is published, I will only discuss with participants in this thread!!!

I am no longer interested in water sports!!!

A senior fellow student who has been engaged in beef cattle production and processing for many years told me that he once did experiments, carefully comparing so-called grass-based cattle raising, pasture + concentrate, straw + concentrate, pasture + straw + concentrate, distillers' grains (baijiu distillers' grains, containing husk shells), and many other models. The final result was that raising cattle with distillers' grains had the lowest cost and could also ensure rapid growth.
