Calculate the Digestibility coefficient of CP of GNC from the above example.
-
From the first trial, it was found that maize fodder has 60 % digestibility for DM, 62 % for CP, 55 % for EE, 56% for CF and 65 % for NFE.
In the second trial, 25 kg of green maize and 1 kg of GNC were fed the animal. The animal excreted on an average 20 kg of faeces. The following was the composition of green maize, GNC and faeces on dry matter basis.
