Abstract

The objective of this work was to determine the profile of fatty acids in feedstuff (concentrate and grasses) used by ruminants in tropical region. This experiment was conducted in five farms located in Pilar do Sul and Sarapuí Cities, State of Sao Paulo, Brazil. The food samples of each farm were taken monthly, during a period from April to November of 2002. The fatty acids involved with the ruminal biohydrogenation (linoleic and linolenic acids) had been lower in B. decumbens in relation to B. ruziziensis in july (39.4% vs 68.2%) and november (51.6% vs 65.7%). The ether extract level increased during the rainy month. The wet brewers grains residue showed high linoleic acid (48.3%), being an important source of precursors for the ruminal biohydrogenation. The sugarcane (0.8%) and the P. purpureum (1.9%) are poor sources in ether extract. The citric pulp is good source of polyunsaturated acids (63.4%).
