That all depends on the type and consistency of this "green fodder," its nutrient quality/value, what you are feeding in addition to the fodder, the moisture level of the fodder, and, for the cow, the weight of the Holstein, if she's dry or lactating, what stage of lactation she is in (if she is lactating), and her age. As such, this question cannot be answerable without providing more information and details in such a way to provide answers to the aforementioned factors and variables.
