          Abstract

          El objetivo del presente estudio fue evaluar el efecto de tres formulaciones minerales (comerciales) sobre los niveles de zinc (Zn), hierro (Fe) y cobre (Cu) en suero sanguíneo de ovejas de pelo. Se seleccionaron 48 ovejas de las razas Pelibuey Canelo y Katahdin, de 2.5 ± 0.5 años de edad, 45.0 ± 5.0 kg de peso y de 2.5 a 4.0 de condición corporal. Se utilizó un diseño completamente al azar, con 12 repeticiones y cuatro tratamientos, los cuales consistieron en la aplicación del suplemento mineral vía parenteral: T1 = testigo (Vit ADE); T2 = 993 mg de P + 45 mg de Se + Vit ADE; T3 = 993 mg de P + Vit D3 + Vit ADE; y T4 = 670 mg de Zn + 987 mg de Mg + 795 mg de Ca + Vit ADE. Las medias de Zn, Fe y Cu fueron 1.56, 3.08 y 0.53 ppm, respectivamente. No se encontraron diferencias significativas entre tratamientos ni en la interacción entre tratamientos x periodos; sin embargo, los periodos afectaron la concentración de minerales en el suero sanguíneo (p<0.05). Se concluye que la suplementación mineral parenteral en ovejas de pelo no afectó de manera significativa la concentración sérica de minerales en ovinos de pelo

          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

            The dynamic link between the integrity of the immune system and zinc status.

            The results of more than three decades of work indicate that zinc deficiency rapidly diminishes antibody- and cell-mediated responses in both humans and animals. The moderate deficiencies in zinc noted in sickle cell anemia, renal disease, chronic gastrointestinal disorders and acrodermatitis enteropathica; subjects with human immunodeficiency virus; children with diarrhea; and elderly persons can greatly alter host defense systems, leading to increases in opportunistic infections and mortality rates. Conversely, short periods of zinc supplementation substantially improve immune defense in individuals with these diseases. Mouse models demonstrate that 30 d of suboptimal intake of zinc can lead to 30-80% losses in defense capacity. Collectively, the data clearly demonstrate that immune integrity is tightly linked to zinc status. Lymphopenia and thymic atrophy, which were the early hallmarks of zinc deficiency, are now known to be due to high losses of precursor T and B cells in the bone marrow. This ultimately leads to lymphopenia or a failure to replenish the lymphocytic system. Glucocorticoid-mediated apoptosis induced by zinc deficiency causes down-regulation of lymphopoiesis. Indeed, zinc itself can modulate death processes in precursor lymphocytes. Finally, there is substantial evidence that zinc supplementation may well reduce the impact of many of the aforementioned diseases by preventing the dismantling of the immune system. The latter represents an important area for research.
