Title: Zinc and Coppers Levels in the Plasma of Nubian Goats as Affected by the Physiological Status.
Author: Hamid,Tag El Din Mohamed
Abstract: This study is undertaken to determine the blood concentration of micro (trace) minerals, particularly Zinc (Zn) and copper (Cu), in dairy goats as affected by the physiological status. Nubian goats were chosen because they are an important dairy breed in Sudan. The animals were divided into eight groups as follows: Young animals ( 4 - 6 months old), Adult animals ( 9 - 12 months old), Pregnant animals ( at first pregnancy), Up to 50 days after first kidding, up to 50 days after second kidding, Up to 50 days after third kidding, low yielders, high yielders. Each of the above groups consisted of 5 animals. The data analysis revealed that plasma Zn concentration decreased with increase of age while that of Cu increased with the increase of age. The plasma Zn level showed continuous increase through first pregnancy, after first kidding, after second kidding and after third kidding. It also increased in the lactating animals. The plasma Cu concentration fluctuated throughout the groups with different physiological status, it showed the same levels in the pregnant group, up to 50 days after second kidding, and up to 50 days after third kidding groups, while it showed a marked decrease in the group of up to 50 days after first kidding. No significant differences were observed between the low lactating and the high lactating groups.
