What proteins do ruminants require?

Ruminants primarily require proteins that are rich in amino acids for growth, maintenance, and milk production. They benefit from both rumen-degradable protein (RDP), which can be broken down by microbes in the rumen, and rumen-undegradable protein (RUP), which bypasses the rumen and is digested in the intestines. Common protein sources include legumes, oilseed meals, and by-products like distillers grains. Ensuring a balanced intake of these proteins is crucial for optimal health and productivity in ruminants.
