GONZALEZ-REYNA, Arnoldo et al. Serum zinc, iron and copper in hair sheep with parenteral supplementation of minerals. Rev. investig. vet. Perú [online]. 2016, vol.27, n.4, pp.706-714. ISSN 1609-9117.  http://dx.doi.org/10.15381/rivep.v27i4.12574.

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
