Goat Farming Feed

I am going to start a goat farm of 500 osmanabadi goats.
I would like to know the feeding structure.
I would like to know what and in what quantity fodder crops should I cultivate being fully self-dependent on feeding the goats.
Also I am thinking of going with boer bucks and osmanabadi does with cross breeding.
Would it help? With what concerns? Will it improve quality and weight increasing capacity of the baby goats? Or will it have any adverse effect?
With best regards.
