How is this formula? Please have an expert take a look.

Today I got a formula from an old veterinarian who has practiced medicine for decades. He graduated from the animal husbandry and veterinary medicine program at an agricultural university, but I personally think there is a bit of a problem with the formula: the proportion of energy feed is too low. What do you teachers think? Please comment, thank you!

The formula is as follows: (the percent signs are all omitted)

Corn 15
Wheat bran 15
Rapeseed cake 5
Cottonseed cake 5
Soybean cake 4
Mixed bran 35
Rice bran cake 18
Shell powder 2
Additives 2 (1 packet)

What kind of feed formula is this
---------------------
Is it a cattle feed formula?

No, what the original poster is asking about is a formula for fattening pigs. I wonder if it is suitable for small-scale pig farms?

Looking forward to an expert taking a look!

Too vague, hard to say. You should first do a comparison,
Not very feasible. What exactly is the mixed bran you mentioned?
