In TMR (totally mixed ration) and PMR (partially mixed rations) feeding systems of high production dairy cows, it is required to use protein - fibrous supplements. This demand is satisfied by a varied range of products of vegetable origin, among them the alfalfa pellet which is very little diffused in our country (though in other countries). As well as being a very good palatability product, the alfalfa pellet´s important source of vitamins and minerals is a comparative advantage towards other protein – fibrous products (wheat pellets, sunflower pellets, etc.)
Alfalfa pellets improve the consumption and utilization of low quality forages, due to the higher density of the tablets compared to hay in the form of a roll, since it occupies less ruminal volume besides being an excellent source of non-degradable protein.
We must remember that fiber is a basic nutrient in the rations of dairy cows, fulfilling two key functions:
- As a voluminous element also called "effective fiber" that acts generating adequate ruminal conditions, through stimulation to chewing and insalivation (saliva is the main buffer of acidity of the rumen).
