The objective was to evalúate the kinetics of degradation in the first compartment (C1) of llamas of the dry matter (DM) of forage F. dolichophylla harvested at 3, 6, 9, 12 and 15 weeks of growth during two seasons (rainy and dry). The degradation kinetics of crude protein (PC), neutral detergent fiber (NDF) and acid detergent fiber (ADF) were evaluated only in the rainy season. In situ degradation was described by the equation of Ørskov et al., (1980) D = a + b (1-exp-ct). A completely randomized block design with a 2 x 5 factorial arrangement was used for the MS. The rate (c) 3.24% h-1, intercept of the curve (a) 22.22%, and the degradation potential of MS (a + b) 91.32%, were not affected (P> 0.05) by the time, age and interaction. However, the effective DM degradation (estimated with a flow rate of k = 2% h-1) was affected (P <0.05) by time and age. The effective degradation of DM decreased 13.9 and 10.7% from 3 to 15 weeks of growth for the rainy and dry seasons, respectively. The degradation rates of PC, 6.7% h-1, NDF, 3.9% h-1 and the FDA, 3.6% h-1, were not affected (P> 0.05) by the age of growth. However, the potential and effective degradation (k = 2% h-1) was influenced by the age of growth, ranging from 97.7 to 90.1%, 86.0 to 80.8%, and from 72.4 to 71.9% from 3 to 15 weeks of increase. The effective degradation of PC, NDF and ADF was affected (P <0.05)bythe agethe a of growth, decreasing from 88.6 to 63%, 63.5 to 57.1%, and from 51.7 to 40.3% from 3 to 15 weeks of growth. It is concluded that the accelerated degradation of the protein at early hours, and low degradation of cell walls causes an imbalance invailability of protein and absence of energy.
Estudio histológico de intestinos y glándulas anexas del conejo

La presente investigación tuvo como objetivo. Describir y comparar la estructura histológica del duodeno, yeyuno, íleon y glándulas anexas digestivas del conejo según edad. Para esta investigación se utilizó 40 conejos de 15, 30, 45 y 60 días de edad de los cuales se obtuvo muestras histológicas del intestino delgado y glándulas anexas. Las muestras de los órganos mencionados fueron procesadas en el Laboratorio de Investigación y Diagnostico en Animales de Altura (LIDCAA) de la Facultad de Ciencias Agrarias y Naturales, Universidad Técnica de Oruro, mediante la técnica histológica con tinción eosina-hematoxilina (EH). De acuerdo a los resultados obtenidos en el presente trabajo, las mismas que se evidencian en fotomicrografías según edad, no se encontró diferencias concretas en la estructura histológica de los tejidos que constituyen del intestino delgado y glándulas anexas de los conejos, la única diferencia que se pudo registrar fue en el tamaño y la cantidad de células que conforman los tejidos analizados. El estudio histológico de los órganos citados, nos permite aclarar que los tejidos digestivos completan su diferenciación desde una edad muy temprana en conejos, por tal razón desde los 15 a 60 días no hubo una diferencia histología marcada.
Prevalencia de Sarcocystis spp. en musculo cardiaco de llamas ( Lama glama ) y alpacas ( Vicugna pacos )

The research was carried out in the municipality of Curahuara de Carangas corresponding to the First Section of the Sajama Province of the Department of Oruro-Bolivia, with the objective of determining the prevalence of Sarcocystis spp., 383 hearts, 229 llamas and 154 alpacas were selected slaughtered for commercial purposes, through the registration form according to species, category and pathological effect, during the months of March to September 2016. After in-situ evaluation, making histopathological cuts, the positive samples were sent to the Animal Health laboratory of the Faculty of Agradan and Natural Sciences, Technical University of Oruro. The results indícate a total of 131 positive alpacas (85.06%) and 23 negative (14.94%), 167 positive llamas (72.93%) and 62 negative (27.07%). On microscopic examination the histopathological alterations of the positive samples to Sarcocystis lamacanis, these being: eosinophilic infiltration, vascular congestión and degeneration of myocardial fibers. The results indícate that this parasitosis is a problem in the breeding of camelids and the data would be an indicator of contamination of grasslands or grazing áreas, which requires the implementation of sanitation control policies in the áreas dedicated to these processes.
