Abstract :The aim of this study was to investigate the relations of the serum zinc and the Vitamin A, b-carotene concentrations depend on physiological conditions and seasonal effects in Angora Goats raised in Lalahan Livestock Research Institute. Healthy, 2-years old Angora Goats insert ignore into journalissuearticles values(n = 26); were used in this study. The blood samples were collected four times through the year to cover the whole seasons. Vitamin A, b-carotene and zinc concentrations of serum samples were measured. The highest serum b-carotene concentrations insert ignore into journalissuearticles values(6.63 ± 0.76 mg/dl); were found in samples taken in the summer and the lowest concentrations insert ignore into journalissuearticles values(1.17 ± 0.36 mg/dl); were found in the samples of the winter. However, the highest serum retinol concentrations insert ignore into journalissuearticles values(27.05 ± 2.50 mg/dl ); were found in spring samples, the lowest concentrations of the retinol insert ignore into journalissuearticles values(13.44 ± 1.09 mg/dl); were found in the samples of the winter. Finally, the highest serum zinc concentrations insert ignore into journalissuearticles values(89.08 ± 1.06 mg/dl); were seen in winter and the lowest concentrations of the zincinsert ignore into journalissuearticles values(63.75 ± 3.59 mg/dl); were found in spring samples. The correlation between serum retinol and zinc concentrations were found to be positive in winter and negative in other seasons although statistically were not important. It could be concluded that serum retinol, b-carotene and zinc concentrations may change in accordance with the season and therefore the diets of the animals should be supplemented with Vit A in winter and with zinc in spring.
