In the study, healthy and adult, 12 Angora goats were used. The animals were divided equally into two groups . Group 1 (Control) and Group 2 (Zn Group) were fed ad libitum with a basal ration and the basal ration supplemented with 250 ppm Zn for 3 months. In the Zn group, plasma Zn levels were found to be significantly (P <0.05) higher than those in the Control group at the all sampling times. While plasma Cholesterol level in the Zn group were found to be higher than Control group during the study, the difference in the month 3 was important (P <0.05). Plasma HDL-C(High density Lipoprotein Cholesterol) levels did not show any differences between groups during the study. Plasma phospholipid levels of Zn group were significantly (P<0.05) higher than in Control group in the month 2, 3. However Erythrocyte membrane phospholipid levels were generally higher in Zn group as compared with Control group and the difference lonely in the month 2 was important (P<0.05) . On the other hand, erythrocyte membrane cholesterol levels were found to be slightly higher in the Zn group unless different from those in Control group. Consequently, the Zn supplementation in Angora goats seems striking in respect of the changes in plasma and erythrocyte membrane lipid fractions, because of the important roles of phospholipids and cholesterol on dynamics and structure of these cells.
