ALONSO CHICAIZA, Luis et al. Effects of Supplementation with Microminerals on Production Indicators and Blood, Feces, and Urine Traces of Grazing alpaca (Lama lama). Rev. prod. anim. [online]. 2016, vol.28, n.2-3, pp.26-32. ISSN 2224-7920.

In this area was applied three doses of selenium and zinc (0.0; 1.0 and 1.5 cc), under a (DCA) in factorial arrangement (3 x 2) + (3 x 2) in order to analyze the effect of the level of additional mineral supplement micro (Selenium, Zinc) to the diet on the raised variables, weight and fiber diameter of alpacas. Results revealed statistical differences for treatment: selenium doses, age, Zinc doses, Zinc interaction for ages. For this, the treatment 4 (Se1E2) with 74.33 kg to 90 days to cross height (Zn1E2) with 91.33 cm average. The length fiber into treatments 3 (Se1E1) and 4 (Se1E2) with 3 cm average. For fiber diameter on treatments 1 (Se0E1) Treatment 3 (Se1E1) of group 1, treatments 8 (Zn0E2) and 9 (Zn1E1) which group 2 charged better fiber quality with 28 microns average. It was confirmed an beneficial effect on live weight and fiber quality in mature animals for mineral supply with Se and Zn con los microelements, that improved the production phenotypical characteristics like weight, but it was manifested minerals urine residuality in 3-5 years old animals.
