The aim of this study was to determine some reproductive parameters (gestation rate, number of young, age distribution and reproductive age) of female vicuñas in two management systems: wild and captivity, in the Cusco Region, Peru. The capture of the animals ("Chaccus") were carried out between May and August 2017. The pregnancy was determined by transrectal ultrasound in 143 females, the presence of offspring by observing functional udder in the females, the age distribution and reproductive age by means of the records of capture and observation of the dentition. The percentage of gestation was of 74.6 and 79.4% for the wild and captivity systems, respectively. In the juvenile population were pregnant 29.9 and 4.4% in the wild and in captivity, respectively. The number of young animals in the wild was 36% and in captivity 53%. The proportion of young vicuñas was similar in both manag...

The aim of this study was to identify and evaluate the cases of scabies caused by Sarcoptes scabiei and endoparasites in wild and captive vicuñas (Vicugna vicugna) from the Cusco Region, Peru. Scrapings of skin lesions were made and faecal samples were taken during the capture of vicuñas during the chaccus. The frequency of S. scabiei was 1.9% (54/2826), being 6.1% (48/777) in the wild and 0.2% (6/2049) in captivity. Likewise, F. hepatica (2.0%), Strongylus type eggs (42.1%), Nematodirus sp (6.8%), N. spathiger (26.5%), Trichuris sp (4.0%), Eimeria spp (85.0%), and Moniezia spp (2.7%) were found in a sample of 147 animals, being most cases monoparasitism.sarna
