Question

A dairy farmer prepared 1000kg of feed (20%DCP) from the following feedstuffs:
Oats – 10% DCP , Simsim seedcake 60% DCP

Calculate the amount of each feedstuff used using Pearson’s square method.

Answer 1

Amount of oats = ⁴⁰/₅₀ x 1000kg
                       = 800kg of oats  
Amount of simsim = ¹⁰/₅₀ x 1000kg
                           = 200kg of simsim
