The alpaca population mostly consists of the Huacaya phenotype and is widely distributed in Southern Peru. This study aimed to estimate the genetic diversity and population structure of two Huacaya alpaca populations (Ajoyani and Quimsachata) using fourteen and twelve microsatellite markers for each population, respectively. A total of 168 alpaca b...

It is well known that objectionable fibres emerge from the surface of the yarn due to the centrifugal force of the spinning device. Furthermore, the hair removal process is based on the same physical principles. However, the fibres that are >30 µm (PcF) are the fibres that appear in the hairiness of the yarn and are eliminated by dehairing. It has...

La importancia de medir el peso al nacer radica principalmente en el manejo que puede dársele al recién nacido en los primeros días de vida, ya que en otras especies como los becerros con pesos muy bajos o altos tienen dificultad para amamantarse (Elzo et al., 1998). El crecimiento en crías de alpacas en Perú ha sido escasamente estudiado, siendo e...

El test hipoosmótico permite evaluar la integridad de la membrana plasmática del espermatozoide. Con el objetivo de evaluar el efecto de la osmolaridad de la solución y la presencia o no de plasma seminal sobre la respuesta al test hipoosmótico en espermatozoides de alpaca se utilizaron 6 machos adultos. Se colectaron espermatozoides mediante vagin...

The aim of the present study was to determine the ovulation rate using GnRH (buserelin) and seminal plasma of alpaca as ovulation inductors in alpacas and llamas. For this, 93 alpacas and 92 llamas were distributed in two groups: a group treated with buserelin (42 μg) IM, and a group treated with 1 ml of seminal plasma IM (50/50% seminal plasma of...
