Abstract

Cattle raising is the most difused activity in the world. The main source of feeding is the grass. In this research, the efficiency of the crude protein (CP) in grass was evaluated using four different feed formulations in the cattle feeding. When the grass had >18 % of CP, the best results were obtained with cattle feed of 12 % of CP and non-nitrogenous elements (NNE) in a 68 %. It increased the milk production and the protein content, and the milk urea nitrogen(MUN) decreased. On the other hand, if the grass had between 14-18 % of CP, the best results were obtained with cattle feed containing CP ≤ of 14 % and the NNE ≥ of 61 %. It also improved the milk production and the protein content, and the MUN level decreased. Whereas, if the CP in the grass was <14 %, it required an additional quantity of CP coming from the cattle feed. The best results were obtained with cattle feed with CP>16 % and NNE <57 %, increasing the milk production and the protein content, improving the content of MUN in milk.
