Class 5: Protein supplements

• The major plant-based protein sources are : Soyabean meal, Groundnut meal, Cotton seed cake, Linseed cake, Mustard cake, and Sesame cake.
• Ruminants break down dietary protein into ammonia and C skeleton through rumen microbes and synthesize their microbial protein.
• Therefore, a portion of a ruminant’s protein requirement can be met with non-protein nitrogen (NPN).
• So, there is the main concern for ruminants for the protein supply, therefore to make sure the majority of protein is available to ruminants, they are fed as by-pass protein.
