Sera of an experimentally Neospora caninum infected llama and a non-infected control llama were used to establish an immunoblot, an ELISA and an IFAT to detect antibodies against N. caninum tachyzoites. Subsequently, serum samples collected from a total of 871 South American Camelids (SAC: Lama glama, Lama pacos, Lama vicugna) of two farms in Peru and from 32 SAC of a farm in central Germany were examined for antibodies against N. caninum and Toxoplasma gondii. Based on the recognition of specific bands in the immunoblot, sera of SAC from Peru were differentiated into N. caninum-positive (n = 18) and T. gondii-positive (n = 30) samples and into samples negative or inconclusive for both parasites. Using the immunoblot results as the reference, a modified version of the p38-ELISA and the IFAT were evaluated for detecting N. caninum antibodies in SAC sera. Applying a cut-off as determined b...

Alpacas and llamas play an important role in the livelihood of many rural families in the High Andes of Peru. The census of 2012 indicates a population of 3 million alpacas and 746,269 llamas. Both species are kept in extensive, low-input, pasture-based systems in altitudes between 3800 m and up to 5000 meters above sea level. Smallholders keep mixed herds of sheep, alpaca and llamas as a mitigation strategy against fluctuating market prices. Since 1997 the Peruvian Ministry of Agriculture manages a genealogy registry for alpacas and llamas, but so far the up-take rate by farmers and inscription rate of animals is low. The national research organisation INIA (Instituto Nacional de Innovación Agaria) runs an ex-situ in-vivo conservation program for coloured alpacas (21 different colours) and llamas. INIA is also doing research in the area of embryo transfer, artificial insemination and c...

The morphology of 284 K’ara llamas was determined through biometric measurements and body weight based on sex and age factors. The animals were from breeder organizations in the Checacupe district of the Cusco Region, Peru. The measurements were grouped into cephalic, body and trunk heights, cane perimeter and body weight. The analysis was carried out in a 2x5 factorial arrangement (2 sexes, 5 ages) under a complete randomized design. At head level, head length is the only one that contributes to sexual dimorphism (p<0.05). Head height showed greater value, attributable to the presence of an elongated and upright neck. Body lengths show sexual dimorphism and have different growth and development. Male neck measurements were greater (p<0.05), except for the length of the neck. At the thorax level, the thoracic perimeter and depth were greater in males (p<0.05). Each morphologic...

La presente investigación analiza el proceso de planificación del territorio y la aplicación de sus instrumentos. Actualmente existen desarticulaciones territoriales que afectan a la población urbano-rural, debido a que no se ha logrado resolver eficazmente la exclusión en su interior. De esta manera, es importante identificar aquellos aspectos propios de una localidad, en este caso en el distrito de Lamas del departamento de San Martín, que configuran un territorio habitado y ocupado a partir del cotidiano de la población. Para entender e identificar cuáles son estos aspectos propios de una localidad que configuran un territorio, se tomó como base teórica el enfoque de territorialidad. Su aplicación en las comunidades nativas que se ubican en el distrito de Lamas permite ir desde lo local, identificando sus principales características como ejes de planificación. Un paso met...

The study was conducted in herds of llamas of peasant organizations in the district of Checacupe, Cusco Region, Peru, to determine the biometric measurements and live weight of the Ch’acu llamas based on sex and age. The measurements were grouped in cephalic, heights at withers and rump, cane perimeter and live weight, under a randomized complete design analysis with 2x5 factorial arrangement (α=0.5). Cephalic measurements showed significant differences in favour of the male (p<0.05), but the length of ears was similar; the heights were similar; body length, dorsal length and distance between shoulders favoured females (p<0.05); the measurements of the neck of the male llamas are different (p<0.05), except the length of the neck and its lower perimeter; females exhibit greater thoracic perimeter (p<0.05), but the thoracic perimeter and depth were similar; the thickness of ...

The objective of this research was to study the distribution and social structure of the guanaco in the Calipuy National Reserve (RNC), La Libertad, Peru. 430 guanacos were reported with a slight downward trend (b = - 10.21), distributed in 114 km2. The adults were most numerous with 73.5% ± 9.8 (p<0.01) followed by juveniles and chulengos 16.1% ± 3.93 y 10.4 ± 5.9 respectively. The 72% of the population was found in family groups, 18% in herds and solitary accounted for 10%. The density was 5.7 individuals per km2. The population was mostly concentrated in the north, above 3000 m (p <0. 01), which is also the most heavily fortified, reaching 18.9 ± 8.97 guanacos/km2 and family groups mainly houses. The western zone under 3000 m and closer to the breeding area, was the lowest density 0.24 ± 0.24 guanacos/km2, and maintained primarily solitary and groups of males.

This study compiles records of endoparasites species in guanacos (Lama guanicoe) from Argentina. A bibliographic review of scientific works published between 1967 and 2017 was conducted. In addition, new unpublished records of localities within the province of San Juan were incorporated. The endoparasite fauna was represented by the phylum Nematoda, Platyhelminthes and Aplicomplexa, with a total of 65 total entries, 26 species mentioned and 14 others that were only identified at the genus level. The nematodes were the most numerous, followed by the Aplicomplexa and to a lesser extent the pylum Platyhelminthes. This work mentions for the first time the presence of nematodes such as Nematodirus sp, Trichuris sp, coccidia E. macusaniensis, E. ivitaensis and Eimeria sp in wild guanacos from the province of San Juan. There were few records in the environment with small populations of guanacos...

This study compared the technological quality of twelve muscles of llama that were raised in a grazing system. The llamas (n=10) were slaughtered using Bolivian standard procedures. Carcasses were stored for 24 h in a cold room (4 ºC). Muscles were removed from the left side of each carcass in the slaughter house. Five steaks (2.54 cm thick) were cut from each muscle. In each muscle was determined pH, holding capacity (WHC) and Warner-Bratzler shear-force (WBSF). No statistical difference was found in pH between muscles. Values of L* (lightness) and b* (tenor of yellow) in L. thoracis, L. lumborum and Semimembranosus were higher than those in Triceps brachii and Psoas major (p<0.05). The cooking loss percentage was lower in Infraspinatus and Longissimus thoracis (p<0.05). The WBSF value in the Semimembranosus, Semitendinosus, Quadriceps femoris and Biceps femoris muscles was highe...

Lamas es un pueblo étnico en la selva peruana, específicamente en San Martín, cuyo origen mixto ha determinado la variación en sus costumbres y creencias en comparación a otro pueblo en la selva peruana. La mezcla de las costumbres andinas y las propias de la zona han influenciaron en el tipo de emplazamiento y han creado obras originales para la región debido al uso mixto de materiales no convencionales para una arquitectura tropical como el tapial y de elementos zonales como la palma o shapaja. En esta investigación se propone analizar la relación entre las costumbres andinas de su origen y los elementos arquitectónicos productos de la adaptación percibidos en la actualidad. Para así, determinar los elementos arquitectónicos y urbanísticos que prevalecieron después del terremoto del 2005 que afectó la mayor parte de la arquitectura vernácula lamista y comprender los sis...
