The aim of this study was to develop a preliminary physical map of single nucleotide polymorphisms (SNPs) in alpaca using an alpaca/hamster radiation hybrid panel and a bovine high- density SNP genotyping microarray (BovineHD BeadChip-Illumina). The methodology included genotyping 92 alpaca/hamster hybrid cell clones, and four control samples (male alpaca, female alpaca, hamster and 1:10 DNA mixture) with the microarray. After genotyping the alpaca and hamster DNA control samples, only bovine SNPs a call frequency of 1 were retained. The SNPs identified in the alpaca DNA samples were then filtered to remove those also in the hamster. From the remaining alpaca SNPs, to decrease the probability of false positives, only those with a call frequency from 0.2 to 0.8 in the 92 hybrid clone samples were retained for the final analysis. The remaining alpaca specific SNPs were tabulated in MapMake...

El objetivo del presente estudio fue evaluar la susceptibilidad del cuerpo lúteo al cloprostenol sódico (análogo sintético de la PGF2α) durante el desarrollo de la fase luteal en alpacas inducidas a ovulación con plasma seminal. El plasma seminal se obtuvo de muestras de semen de alpaca colectadas mediante vagina artificial y diluidas en proporción 1:1 en buffer fosfato salino (PBS), luego fueron centrifugadas y conservadas a -20°C hasta su posterior uso. 96 alpacas hembras con un folículo ≥7mm fueron inducidas a ovulación mediante la inyección de plasma seminal (n=48) y GnRH (n=48). Luego fueron seleccionadas aleatoriamente en 6 grupos distintos: un grupo control y animales tratados con PGF2α los dias 4, 5, 6, 7 y 8 post inducción de ovulación. Se colectaron muestras sanguíneas para determinar los perfiles de progesterona sérica al inicio del tratamiento y 24 horas pos...
