Suplementación de raciones para cebo intensivo de terneros con aceites vegetales: rendimientos productivos, calidad de la canal, de la grasa y de la carne

Se han estudiado los efectos de la incorporación de aceites de origen vegetal sobre los rendimientos productivos, calidad de la canal y de la grasa en el ganado vacuno. Se utilizaron 240 terneros agrupados en 24 lotes de 10 terneros cada uno. Las raciones experimentales fueron: Tratamiento Control (4% de aceite de palma), Oliva (4,8% de jabón cálcico de aceite de oliva), Soja (4% de aceite de soja). De cada lote se seleccionó al azar un ternero (8 terneros por tratamiento) para diseccionar su 6ª costilla. No se han observado diferencias significativas entre tratamientos para ningún parámetro productivo ni de calidad de la canal. Los animales que consumieron aceite de oliva presentaron un mayor contenido (P=0,09) en C18:2 cis-9, trans-11 CLA en la grasa intramuscular que los que consumieron palma

Suplementación de raciones para cebo intensivo de terneros con aceites vegetales: calidad de carne

Se han estudiado los efectos de la incorporación de aceites de origen vegetal sobre la calidad de carne en el ganado vacuno. Se utilizaron 240 terneros agrupados en 24 lotes de 10 terneros cada uno. Las raciones experimentales fueron: Tratamiento Control (4% de aceite de palma), Oliva (4,8% de jabón cálcico de aceite de oliva), Soja (4% de aceite de soja). De cada lote se seleccionó al azar un ternero (8 terneros por tratamiento) para diseccionar su 6ª costilla. Se tomaron medidas de pH, color y textura del músculo Longissimus dorsi. Por último se realizó un análisis sensorial mediante un panel de catadores en el que se analizaron los parámetros de olor, textura y flavor de la carne. La carne de los animales alimentados con aceite de palma (Control) presentó el valor más alto (P0,05). En el análisis sensorial de la carne no se han observado diferencias significativas en los parámetros estudiados

Determinación de Valores Normales en Electrococleografía. Centro Médico Naval, 1993 - 1995

OBJECTIVE: To determine latency times for electrocochleographic waves in normal subjects. METHODS: During a 23-months period, 98 subjects from the Service of Otorhinolaringology at the Centro Médico Naval, Callao - Perú, underwent a single healthy ear electrocochleographic test of each individual. RESULTS: Mean latency times were similar to those redorded in other series. Among patients with 15 years-old or lesser (6,1%), latency times were longer than the average. There were no significant differences among latency times regarding to the ear side or gender. CONCLUSIONS: Electrocochleographic latency values were related to myelinization level or neurologic development of the auditive pathways.OBJETIVO: Determinar los tiempos de latencia de las ondas electrococleográficas en pacientes normales en nuestro medio. MÉTODOS: El estudio se realizó en el Servicio de Otorrinolaringología del Centro Médico Naval, Callao - Perú, durante 23 meses. Se evaluó 98 personas (50 hombres y 48 mujeres) tomando un solo oído sano de cada uno. RESULTADOS: Los tiempos de latencia promedio encontrados en los exámenes de electrococleografía realizados en los 98 pacientes fueron compatibles con los valores hallados en otros países. En los pacientes menores de 15 años (6,1%) los tiempos de latencia se encontraron más prolongados que en el promedio. Los tiempos de latencia de acuerdo al oído examinado y según sexo no muestran diferencia significativa. CONCLUSIONES: Los valores de latencia en la electrococleografía dependen directamente del grado de mielinización o madurez neurológica de la vía auditiva

Animal performance and meat characteristics in steers reared in intensive conditions fed with different vegetable oils

Enhancing the quality of beef meat is an important goal in terms of improving both the nutritional value for the consumer and the commercial value for producers. The aim of this work was to study the effects of different vegetable oil supplements on growth performance, carcass quality and meat quality in beef steers reared under intensive conditions. A total of 240 Blonde D’ Aquitaine steers (average BW=293.7±38.88 kg) were grouped into 24 batches (10 steers/batch) and were randomly assigned to one of the three dietary treatments (eight batches per treatment), each supplemented with either 4% hydrogenated palm oil (PALM) or fatty acids (FAs) from olive oil (OLI) or soybean oil (SOY). No differences in growth performance or carcass quality were observed. For the meat quality analysis, a steer was randomly selected from each batch and the 6th rib on the left half of the carcass was dissected. PALM meat had the highest percentage of 16:0 (P<0.05) and the lowest n-6/n-3 polyunsaturated fatty acids (PUFA) ratio (P<0.05), OLI had the highest content of t11-18:1 (P<0.01) and c9,t11-18:2 (P<0.05) and SOY showed the lowest value of monounsaturated fatty acids (MUFA) (P<0.001), the highest percentage of PUFA (P<0.01) and a lower index of atherogenicity (P=0.07) than PALM. No significant differences in the sensory characteristics of the meat were noted. However, the results of the principal component analysis of meat characteristics enabled meat from those steers that consumed fatty acids from olive oil to be differentiated from that of steers that consumed soybean oil.Depto. de Producción AnimalFac. de VeterinariaTRUEpu

Site-specific scaling of remote sensing-based estimates of woody cover and aboveground biomass for mapping long-term tropical dry forest degradation status

Remote sensing-based approaches are important for evaluating ecosystem degradation and the efficient planning of ecosystem restoration efforts. However, the large majority of remote sensing-based degradation assessments are trend-based, implying that they can only detect degradation that occurred after medium or high-resolution satellite imagery became available. This makes them less suitable to map long-term degradation in ecosystems that have been under high human pressure since before. The main goal of this study was to develop a robust operational approach to map forest degradation status in heterogeneous landscapes with a long-standing degradation history to inform the planning of restoration interventions. We hereby use the tropical dry forests of Lambayeque, Peru, as a case study. Instead of using a trend-based assessment, we evaluated forest degradation status by comparing current woody cover (WC) and aboveground biomass (AGB) estimates obtained from remote sensing imagery with benchmark values consisting of the 95th percentile WC and AGB values inside environmentally homogenous land capability classes. Using boosted regression tree models and a combination of optical (Sentinel-2) and synthetic aperture radar (Sentinel-1) data of different seasons, we mapped WC and AGB, using training data obtained through very high-resolution imagery and field measurements. Further, we aimed at assessing (i) whether the inclusion of Sentinel-1 data improves mapping accuracy in comparison to using only Sentinel-2 data, and (ii) whether the use of multi-seasonal data improves accuracy in comparison to single-season data. Models combining multi-seasonal Sentinel-1 and Sentinel-2 data resulted in the most accurate WC predictions (mean absolute error (MAE): 16%; MAE normalized by dividing by the inter-quartile range of training data: 26%) and AGB predictions (MAE: 28.6 t/ha; normalized MAE: 65%), but differences in predictive accuracy with single season models or models using only Sentinel-2 data were small. The most accurate models estimated an average WC of 41% and an average AGB of 23.4 t/ha. Average WC and AGB reduction due to degradation was 35% and 36%, respectively, indicating that these forests are highly degraded. The site-specific scaling of WC and AGB allows to efficiently estimate forest degradation status irrespective of the time when this degradation occurred, and to express degradation status against site-specific benchmarks. On the condition that there are still some areas that are sufficiently undegraded to be used as a benchmark, the approach can be used to prioritize forest restoration actions and inform targets for restoration in heterogeneous landscapes suffering the impacts of undocumented long-term degradation
