The study aimed to describe the microbiota present in alpaca semen. Fifteen semen samples were collected using the artificial vagina, electroejaculation and post-copula techniques (five per technique). In addition, preputial (n=5) and vaginal (n=5) swabs were made. Microbiological cultures were made to determine the bacterial and fungal genera and an assessment of the bacterial load by determining the number of colony-forming units (CFU/ml). Six bacterial genera were identified in the vagina and seven in the prepuce, in addition to a fungal species (Aspergillus fumigatus). Bacteria of the genera Escherichia, Staphylococcus, Streptococcus and Bacillus were the most abundant and present in semen obtained by the three techniques, coinciding with those found in preputial and vaginal swabs. The amount of CFU/ml was similar for the three techniques, while there was no presence of fungi in the ...

The aim of this study was to describe the arterial supply of the uterine-fetoplacental complex in alpacas during gestation. In total, 26 female alpacas were used; of these, 5 non-pregnant females were used to describe the irrigation of the reproductive tract and the origins of its irrigation; and 21 pregnant females were distributed in subgroups of 7 and slaughtered when they reached the 1st, 2nd and 3rd third of gestation, respectively. The specimens were processed using the filling-corrosion technique. Observation of uterine irrigation in pregnant and non-gravid uteri shows that it originates from the abdominal aorta artery, from where the ovarian arteries emerge, which pass towards the ovaries and from where they continue through the cranial uterine arteries and enter the uterine horns where they anastomose with the lateral and ventral branches of the caudal uterine arteries that take...
