Abstract

PAXIPATTY-QUISPE, Víctor Abdón et al. Effect of six energetic substrates on the time of sperm viability of the semen of Alpaca (Vicugna pacos L.). J.Selva Andina Anim. Sci. [online]. 2017, vol.4, n.1, pp.38-58. ISSN 2311-3766.

The research was carried out in the Laboratory of Reproductive Biotechnology of the UAC Tiahuanacu, Ingavi province of the Department of La Paz, dependent of the Bolivian Catholic University, whose objective was to evaluate the effect of six energetic substrates on the sperm viability time of the alpaca semen (Vicugna pacos L.). The collected semen was diluted and stored in six different energy substrates (TCG, TCAP, TCF, TG, TAP and TF), a T ° of 35 ºC, evaluating every 2 hours, using the Completely Random Design (P < 0.05). Obtaining a mean volume of semen 1.5 ± 0.7 mL, filament 5.1 ± 1.5, pH 7.2 ± 0.5, motility and vitality of 89.0 and 95.0% and concentration 82.0x106 Epz / mL. The energetic substrate (SE) TCG managed to maintain a motility of 61.0 and 66.0% of vitality preserved for 8 hours, in that sense it is recommended to use the SE TCG, which maintained for a longer time (hours) the viable spermatozoa for LAI.
