Serum zinc, iron and copper in hair sheep with parenteral supplementation of minerals

Abstract

The objective of this study was to evaluate the effect of three mineral formulations (commercial) on the serum concentration of zinc (Zn), iron (Fe) and copper (Cu) of hair sheep. A total of 48 Pelibuey Canelo and Katahdin sheep, 2.5 ± 0.5 years old, 45.0 ± 5.0 kg body weight and 2.5 to 4.0 body condition score were selected. A completely randomized design with 12 repetitions and four treatments was used. Mineral supplements via parenteral were supplemented as follows: T1 = (Vit ADE) control; T2 = 993 mg P + 45 mg of Se + Vit ADE; T3 = 993 mg of P + Vit D3 + Vit ADE; and T4 = 670 mg Zn + 987 mg Mg + 795 mg of Ca + Vit ADE. The mean values of Zn, Fe, and Cu were 1.54, 3.08 and 0.53 ppm respectively. No significant differences were found between treatments nor in the interaction treatments x periods; however, periods significantly affected the serum concentration of minerals (p<0.05). It is concluded that parenteral mineral supplementation in hair sheep do not significantly affect serum concentration of minerals.
