Animals’ Demand for Choline Chloride

Natural choline exists in most of feed. The content is usually low in grain products,

but rich in certain oil seeds and meat.

Table One: Content of Natural Choline

Table Two: Different Animals’ Demand for Choline Chloride (unit:mg/kg)

according to NRC Standard

The amount of choline chloride in feed depends on its composition and animals’

demand for choline. Table two shows us the total amount of choline that animals

require. To calculate how much choline should be added in animal feed, firstly we

should know the amount of digestible natural choline in feed and then add the

appropriate choline chloride. Therefore, animals’ diet can be optimized.
