Since 1937, qe P. T. WEISS and Peruvian ZAVALETA published the first case of deep mycosis called South American Blastomycosis, this condition has been the subject of study with us having so far referred 20 cases and 10 published under study and reason Thesis (OR), all from our Amazon.

The aim of the present study was to evaluate the effect of pinto peanut Arachis pintoi in guinea pigs in the growing stage. The experiment lasted for 49 days and included 64 weaned male guinea pigs, arranged in a completely randomized block design with four treatments (0, 5, 10, 15% levels of A. pintoi meal), with four repetitions and four guinea pigs per repetition The results indicate that there was no significant difference between A. pintoi levels for body weight gain, feed intake, feed conversion, carcass yield and economic retribution.

This study aimed to determine the apparent digestibility coefficients and digestible energy of dry velvet bean fodder (Mucuna pruriens). The indirect method was used, considering as a basal diet the concentrate used in the university guinea pig farm (Lima, Peru). The experiment had an adaptation phase (14 days) and a faecal collection phase (5 days). Ten adult male 3-month old guinea pigs randomly distributed in individual metabolic cages were used. Five animals were fed the basal diet and the other five with the experimental diet: 80% basal diet and 20% dry velvet bean fodder. The apparent digestibility coefficients obtained for the dry velvet bean were: 66.29% dry matter, 66.13% organic matter, 74.02% crude protein, 50.82% crude fibre, 60.18% ether extract, 78.22% nitrogen-free extract and 73.33% ash. The estimated digestible energy value was 2.61 kcal/g.

El objetivo del presente estudio fue evaluar el efecto del uso de harina de maní forrajero Arachis pintoi en cuyes en etapa de crecimiento. La duración experimental fue de 49 días, empleándose 64 cuyes machos destetados, dispuestos en un diseño de bloques completamente al azar con cuatro tratamientos (0, 5, 10, 15% de niveles de inclusión de harina de A. pintoi), con cuatro repeticiones y cuatro cuyes por repetición. Los resultados indican que no hubo diferencia significativa entre los niveles de A. pintoi para ganancia de peso, consumo de alimento, conversión alimenticia, rendimiento de carcasa y retribución económica.

This study was carried out to determine the digestibility coefficients and digestible energy of Arachis pintoi, Stylozanthes guianensis, Erythrina poeppigiana, Centrocema macrocarpum and Pueraria phaseoloides. The direct method was used, using the same forage as the only food. The experiment had two phases, one for adaptation and one of faeces collection, with duration of 15 and 5 days, respectively. We used 25 male guinea pigs in growth stage distributed in order to get 5 guinea pigs for each tropical legume evaluated. The digestibility coefficients of nutrients were numerically higher for Arachis pintoi (51,96, 56,80, 29,46 y 71,32 percent of the dry matter, crude protein, crude fiber and nitrogen free extract digestibility, respectively) than for all the other treatments, except for the ash. Likewise, digestible energy values (in dry basis) were greater for Arachis pintoi (2,20 kcal/g...

El presente estudio tuvo como objetivo evaluar económicamente tres niveles de calcio y fósforo (T1: 1,0 de Ca y 0,80% de P; T2: 1,1% de Ca y 0,88% de P; T3: 1,2% de Ca y 0,96% de P) en la dieta de cuyes durante las etapas de gestación y lactancia mediante la comparación de los resultados productivos al destete. Para lo cual se analizaron al término de la gestación el tamaño y peso de camada al nacimiento las ganancias de peso de las hembras reproductoras al parto, su consumo de alimento y conversión alimenticia y al finalizar la lactancia el tamaño y peso de la camada al destete, peso individual de las crías, ganancia de peso de las madres y consumo de alimento. En ese sentido, se emplearon 18 cuyes hembras en inicio de gestación, dispuestas en un diseño completo al azar (DCA), con tres tratamientos y seis repeticiones. En la primera fase los parámetros ganancia de peso y co...

Sweet potato (Ipomoea batatas L) is the main component in the diet of millions of people living in tropical countries, and an improvement in β-carotene content could increase the supply of vitamin A to meet a greater part of the daily requirements of people. In the present study, the content of β-carotene (BC), iron (Fe) and zinc (Zn) were determined in 25 genotypes of sweet potato from two localities: La Molina and SanRamón. Furthermore, the changes in BC content in seven sweet potato genotypes were investigated using different cooking methods and storage times. The content of BC was measured via absorbance at 450 nm and identified through HPLC while Fe and Zn content were determined through ICP-OES techniques. The results show significant variation between genotype, environment and in the genotype-environment interaction. BC content in freshly harvested raw root ranged from 7.62 to ...

El camote (Ipomoea batatas L) es el principal componente en la dieta de millones de personas que viven en países tropicales, y un mejoramiento en el contenido de â-caroteno podría incrementar el suministro de vitamina A para satisfacer la mayor parte de las necesidades diarias de la gente. En el presente estudio, el contenido de â-caroteno (BC), hierro (Fe) y zinc (Zn) fueron determinados en 25 genotipos de camote provenientes de las localidades de La Molina y San Ramón (Perú). Así mismo, los cambios en el contenido de BC en siete genotipos de camote fueron investigados usando diferentes métodos de cocción y tiempos de almacenamiento. El contenido de BC fue medido vía absorbancia a 450 nm e identificado a través del HPLC y el contenido de Fe y Zn fueron determinados a través de técnicas de ICP-OES.

The experiment was conducted to determine the digestibility coefficients and digestible energy of kudzu meal (Pueraria phaseoloides) in guinea pigs. Ten male guinea pigs of 12 weeks and 828 g of average weight were placed in metabolic cages. Five animals were fed the basal diet (wheat by-product) and the other five were fed with the experimental diet (60% wheat by-product and 40% kudzu meal). The indirect method was used for these determinations. The wheat by-product meal was used as a basal feed and its digestibility coefficient was determined by the direct method. There was a 14-day pre-experimental phase for the adaptation of the animals to the facilities and the new diet. The experimental phase was six days, in which the stool collection was performed. In both phases, feed consumption was measured daily. The apparent digestibility coefficients obtained were: 42.90% dry matter, 40.57%...

The intensive poultry systems generate organic waste (poultry manure and poultry litter); which, when used fresh, cause negative impacts to the environment, however, these organic residues are rich in nutrients that can be used as soil amendments, being the biochar production an alternative for their use. In this investigation, the biochar production was carried out with a pyrolyzing furnace (5 kg capacity). Measuring in the production stage the parameters: temperature, yields and density of the resulting material. Likewise, the raw material (chicken and poultry litter) and the biochar obtained were characterized, determining: pH, humidity, ash, total organic carbon and contents of the macro and micronutrients. When evaluating the properties of the biochar, statistically significant differences were obtained between the poultry litter and chicken manure in yields, density, pH, humidity, ...
