What Protein is in your Calf Feed? There are two main types of Protein – Rumen Degradable Protein (RDP) and By-Pass Protein. Calves do not have a fully functioning rumen until they are approximately 100-120Kg! So that means calves require quality By-Pass Proteins to grow. This includes Soya and Canola being the best form of protein. Stay Away from the likes of DDGs and Peas due to being dominant RDP. Calves can not utilise RDP proteins until they have a fully functioning rumen. Did you know, the type and quality of protein calves consume pre-puberty impacts the type of tissue forming in the heifer calf’s mammary system! It is important to avoid fatty tissue laydown in the mammary. Quality By-Pass Proteins have proven to reduce fatty tissue laydown and have improved heifer mammary development. Mammary development impacts the longevity of the udder, milk production and performance ability. Just because the package says 20% protein, that does not mean the calf can utilise the type of protein in their feed. Not all calf feeds are created equal, check the ingredients and the bio- availability of the feed to determine what calf feed is best for calf growth and development. |
