To assess the impact of I supplementation to a L. leucocephala diet, 12 evenly distributed intact and castrated goats were divided into groups (I0 and I100). The I100 was provided with supplemental potassium iodide solution at 0.1 mg/day/animal. Wheat straw was given ad libitum as source of roughage during the experimental period of 105 d. Blood samples were collected at the beginning (d 0) and at 30, 60 and 90 d after experimental feeding. Results revealed that the serum glucose was significantly higher (P<0.01) in I100 group as compared to I0. Haemoglobin, PCV and serum concentrations of total protein, albumin, globulin, Ca and inorganic P and alkaline phosphatase was not affected by I supplementation. Serum levels of triiodothyronine were comparable between the 2 groups while thyroxine increased significantly (P<0.001) in the I100 group. The triiodothyronine:thyroxine ratio was also similar between both groups. It is suggested that the adverse effect of L. leucocephala feeding on thyroid gland could possibly be alleviated by extra iodine provision but this needs further study.
