Zinc and Copper Profile of Blood Plasma and Wool in Kivircik Lambs Reared under Intensive Management Conditions

Abstract

The aim of this study was to determine Zinc (Zn) and Copper (Cu) levels of plasma and wool in Kivircik lambs at the end of the suckling period. For this purpose, blood and wool samples were taken from 48 non-castrated healthy Kivircik male lambs, 32 single-born, and 16 twin-born. The concentration of Zn and Cu together with iron (Fe), sodium (Na), and potassium (K) in plasma, wool, and feedstuffs samples were performed by using a flame atomic absorption spectrophotometer. The result of this study showed that the birth type did not affect the wool mineral level (P > 0.05). However, it was understood that Zn and Cu tended to accumulate more in wool in twin -born lambs. Also, there was a significant negative correlation observed in plasma Cu - Fe concentrations (P < 0.05) while K - Na in plasma, and Cu - Na and Na - K concentrations in wool were positively correlated (varied between P < 0.05 and P < 0.01). It is concluded that Zn and Cu concentration in plasma and wool of Kivircik lambs within the normal range in the suckling period under intensive management conditions. On the other hand, considering the physiological stage of animals and pasture allowance, supplementation of these minerals from organic and/or inorganic sources may be necessary for further times.
