Rumen-protected fat supplements – product types and categories
There is a plethora of rumen-protected fat supplements on the market targeted to ruminant animals and in particular, dairy cows. It is important to remember that fats are not simply energy sources and individual fatty acids have different metabolic functions which help determine the effect they may have on animal production.
A summary of the primary rumen-protected fat product types available commercially is presented in Table 1. Most supplements are suited to beef cattle and other meat-producing animals, while the choice for dairy cows and other milk-producing animals is more-dependent on the objectives of the target farm and what they are aiming to achieve.
