Which of the following is commonly used as a source of plant protein in livestock ration?

Groundnut cake is commonly used as a source of plant protein in livestock ration. Groundnut cake is a by-product of groundnut oil extraction, and it contains a high percentage of protein, making it a valuable source of protein in animal feeds. It is often used as a replacement for soybean meal in livestock rations, especially in areas where soybean meal is not readily available or is too expensive. Maize, rice bran, wheat bran, and molasses are also commonly used in livestock rations, but they are not typically used as a primary source of protein.
