Abstract
Los intentos de criopreservar semen en camélidos sudamericanos, han sido hasta la fecha insatisfactorios. Falta información acerca de los componentes bioquímicas del semen eyaculado y su alta viscosidad que impide el aprovechamiento de material genético. El objetivo de esta investigación se centró en analizar la composición del plasma seminal intrauterino y por aspiración poscoital en llamas. Se seleccionaron 6 llamas machos de 3 y 4 años de edad, la colección de semen fue realizada por aspiración poscoital con el proctoscopio de uso humano, depositado en un tubo falcón de 14 mL después de la cópula. El semen se centrifugo a 2800 rpm/15 min, para posterior análisis en laboratorio se utilizaron kits comerciales (Beckman Coulter y Medicon), y dos analizadores automáticos (Beckman Sxjnchron Cx7 Deltay Pictus 500 Diatron). Para el análisis de los datos se realizó mediante la prueba de t-Student. No hubo diferencia estadística para las concentraciones de albúmina, glucosa, triglicéridos, proteína total, micro proteína, colesterol, fosfatasa alcalina, sodio, calcio y magnesio entre edades (p≥0.05), la concentración de potasio reporto los valores de 10.8±0.56 y 9.76±0.64 mEq/L, siendo estadísticamente diferentes entre edades (p≤0.05). Los resultados de la investigación permiten trabajar con llamas de 3 y 4 años de edad para donadores de semen en programas de inseminación artificial con semen fresco.
Attempts to cryopreserve semen in southamerican camelids have so far been unsatisfactory. There is a lack of information about the biochemical components of ejaculated semen and its high viscosity that prevents the use of genetic material. The objective of this research was to analyze the composition of the intrauterine seminal plasma and by postcoital aspiration in flames. Six male 3 and 4 year oíd llamas were selected, the collection of semen was made by postcoital aspiration with the proctoscope of human use, deposited in a falcon tube of 14 mL after copulation. The semen was centrifuged at 2800 rpm/15 min, for later analysis in the laboratory, commercial kits (Beckman Coulter and Medicon), and two automatic analyzers (Beckman Sxjnchron Cx7 Deltay Pictus 500 Diatron) were used. For the analysis of the data, it was carried out using the t-Student test. There was no statistical difference for the concentrations of albumin, glucose, triglycerides, total protein, micro protein, cholesterol, alkaline phosphatase, sodium, calcium and magnesium between ages (p≥0.05), the potassium concentration reported valúes of 10.8 ± 0.56 and 9.76 ± 0.64 mEq / L, being statistically different between ages (p≤0.05). The results of the research allow us to work with 3- and 4-year-old llamas for semen donors in artificial insemination programs with fresh semen.
