The objective of this research was to evaluate the possibility of including Castor or Licuri oil at two levels in the diets of crossbred Moxotó goat's through dry matter intake, digestibility and levels of urea, glucose and nonesterified fatty acids (NEFA) in the blood. The treatments consisted of control groups without oil, 3% or 5% of Licuri (LO-3 or LO-5) or Castor (CO-3 or CO-5) oil, based on dry matter supplementation. Ten Moxotó lactating goats were used according to a double Latin Square (5 x 5) experiment design. The addition of oil to the diet reduced the dry matter intake, except for animals that were supplemented with CO-3. However, the addition of 3% of oil didn't alter the intake of metabolizable energy and crude protein. The animals supplemented with LO-5 oil showed smaller nutrients intake, except for ether extract intake. The lipid supplement didn't alter the dry matter digestibility, however increased the NDF digestibility the CP and EE apparent digestibility. There was no difference among the glucose levels, urea and NEFA in the blood. It is possible to use 3 %Castor oil in the diet of lactating goats. [ABSTRACT FROM AUTHOR]
