Resumen
En el presente estudio se describe la biometría de la gestación de la alpaca (Vicugnapacos). Se determinó el diámetro abdominal en forma mensual de 10 alpacas gestantes.Además, se colectaron 49 úteros grávidos del camal de Maranganí (Cusco, Perú) yfueron clasificados por edad gestacional conocida mediante fecha de empadre (cada 30días a partir del día 30 al día 330 [± 15 días]). Los úteros grávidos fueron pesados ymedidos, se midieron los fluidos alantoideo y amniótico, y se determinó el peso y lalongitud del feto. Los resultados indican un ligero incremento del diámetro abdominalhasta el final de la gestación, el feto incrementa su peso gradualmente a medida queavanza la gestación, siendo mayor a partir del sexto mes. El largo total del feto se incrementadesde el noveno mes. El líquido amniótico representa menos del 18% del volumen dellíquido alantoideo, ambos fluidos presentan bajos volúmenes. Se pudo observar unincremento de los fluidos hacia el quinto mes, una disminución hasta el noveno mes, yposterior incremento hasta la fecha de parto.
The gestation biometrics of the alpaca (Vicugna pacos) are described. The abdominal diameter was determined monthly from 10 pregnant alpacas. In addition, uterus of 49 pregnant alpacas were collected from the Maranganí herd (Cusco, Peru) and classified by gestational age known as mating date (every 30 days from day 30 to 330 [± 15 days]). Gravid uteri were weighed and measured, allantoic and amniotic fluid was removed and measured, and fetal weight and length were determined. The results indicate a slight increase in abdominal diameter until the end of gestation, the fetus gradually increases its weight as gestation progresses, being greater from the sixth month onwards. The total length of the fetus increases from month nine. The amniotic fluid represents less than 18% of the volume of the allantoic fluid, both fluids have low volumes. An increase in fluids could be observed towards month fivem a decrease until month nine, and a subsequent increase until the delivery date.
