Abstract

Juvenile, 1-g Colossoma macropomum (Cuvier) were fed two different diets: one with fish meal and another with soya meal as the main dietary protein source. Both diets were provided at ad libitum feeding level, and at two restricted feeding levels of ≃ 80% and 60% of the ad libitum level. The experiment was performed in 30 aquaria, each stocked with 12 fish. For each treatment (two diets x three feeding levels), there were five replicates. Fish were fed three times daily at 0900, 1300 and 1700 h. At sampling days (days 14, 29, 44) in each aquarium in one of these feedings, chromic-oxide-marked feed was used. Shortly after the last meal, fish were weighed and four fish were taken from each aquarium for determination of the chromic oxide content in their digestive tract. Fish fed the fish meal diet attained a higher weight but had a lower body protein content. At the ad libitum feeding level, feed intake of the fish meal diet was higher, but feed and protein utilization efficiency were lower than with the soya diet. However, statistical analysis of the data of both the ad libitum and the two restricted feeding levels revealed that the reduced voluntary feed intake of the soya diet was the cause of its better utilization with ad libitum feeding. There is no evidence that soya protein is more freely available than fish meal protein. The chromic oxide data showed that 15 min after feeding, all of the feed (99.8%) could be traced back in fish fed the lowest feeding level, while at the ad libitum feeding level the recovery was only 72%. These data confirmed the hypothesis that at high feeding levels, considerable amounts of feed remain uneaten. Feed losses were not significantly different between the two diets. The chromic oxide recovery data of the 0900 h and 1300 h feedings showed that the feed passage rate in the digestive tract was similar for the three different feeding levels. Due to the high feed losses at high feeding levels, the relation between feed ration and feed utilization is determined mainly by the percentage of feed losses at the different feed rations. Los juveniles de Colossoma macropomum (Cuvier) de 1 g se alimentaron con dos dietas diferentes: una con harina de pescado y otra con harina de soja como principal fuente de proteína dietética. Ambas dietas se proporcionaron con un nivel de alimentación ad libitum y con dos niveles de alimentación restringidos de ≃ 80 % y 60 % del nivel ad libitum. El experimento se realizó en 30 acuarios, cada uno con 12 peces. Para cada tratamiento (dos dietas x tres niveles de alimentación), hubo cinco repeticiones. Los peces fueron alimentados tres veces al día a las 0900, 1300 y 1700 h. En los días de muestreo (días 14, 29, 44) en cada acuario en una de estas alimentaciones, se utilizó alimento marcado con óxido de cromo. Poco después de la última comida, se pesaron los peces y se tomaron cuatro peces de cada acuario para determinar el contenido de óxido de cromo en su tracto digestivo. Los peces alimentados con la dieta de harina de pescado alcanzaron un mayor peso pero tenían un menor contenido de proteína corporal. En el nivel de alimentación ad libitum, el consumo de alimento de la dieta de harina de pescado fue mayor, pero la eficiencia de utilización del alimento y la proteína fue menor que con la dieta de soya. Sin embargo, el análisis estadístico de los datos tanto del nivel de alimentación ad libitum como de los dos niveles de alimentación restringida reveló que la reducción del consumo voluntario de alimento de la dieta de soja fue la causa de su mejor utilización con la alimentación ad libitum. No hay evidencia de que la proteína de soya esté más disponible que la proteína de harina de pescado. Los datos de óxido de cromo mostraron que 15 minutos después de la alimentación, todo el alimento (99,8 %) se pudo rastrear en los peces alimentados con el nivel de alimentación más bajo, mientras que en el nivel de alimentación ad libitum la recuperación fue solo del 72 %. Estos datos confirmaron la hipótesis de que a altos niveles de alimentación, quedan cantidades considerables de alimento sin comer. Las pérdidas de alimento no fueron significativamente diferentes entre las dos dietas. Los datos de recuperación de óxido de cromo de las alimentaciones de las 09:00 h y las 13:00 h mostraron que la tasa de paso del alimento en el tracto digestivo fue similar para los tres niveles de alimentación diferentes. Debido a las altas pérdidas de alimento a altos niveles de alimentación, la relación entre la ración de alimento y la utilización del alimento está determinada principalmente por el porcentaje de pérdidas de alimento en las diferentes raciones de alimento.

Abstract

Juvenile Colossoma macropomum were fed ad libitum diets containing either 30% or 40% protein, while the dietary lipid level varied between 5% and 20%. Growth and protein utilization efficiency increased with the dietary lipid level. However, the economic feasibility of the addition of extra dietary lipid to C. macropomum diets is questionable, as for every extra gram of protein deposition it was necessary to replace 20-25 g of dietary carbohydrates by lipids. Moreover, increased dietary lipid levels resulted in increased lipid deposition. In C. macropomum, feed uptake was regulated by the dietary protein level and unaffected by the dietary lipid level. Dissection of the body into head, viscera and trunk revealed that 45-48% of the body lipids were stored in the trunk, independent of diet composition. A positive relation between dietary and body protein level was confirmed in this experiment. However, the dissection of the body revealed that the body protein concentrations in head -I- viscera and trunk are not changed significantly by the dietary protein level. The higher protein contents offish fed higher-protein diets are due to an increase in the relative weight of the trunk (muscle) to the total body weight. Los juveniles de Colossoma macropomum fueron alimentados con dietas ad libitum que contenían 30% o 40% de proteína, mientras que el nivel de lípidos en la dieta varió entre 5% y 20%. La eficiencia de crecimiento y utilización de proteínas aumentó con el nivel de lípidos en la dieta. Sin embargo, la viabilidad económica de la adición de lípidos dietéticos adicionales a las dietas de C. macropomum es cuestionable, ya que por cada gramo adicional de deposición de proteínas fue necesario reemplazar 20-25 g de carbohidratos dietéticos por lípidos. Además, el aumento de los niveles de lípidos en la dieta resultó en un aumento de la deposición de lípidos. En C. macropomum, el consumo de alimento estuvo regulado por el nivel de proteína en la dieta y no se vio afectado por el nivel de lípidos en la dieta. La disección del cuerpo en cabeza, vísceras y tronco reveló que el 45-48% de los lípidos corporales se almacenaban en el tronco, independientemente de la composición de la dieta. En este experimento se confirmó una relación positiva entre la dieta y el nivel de proteína corporal. Sin embargo, la disección del cuerpo reveló que las concentraciones de proteína corporal en la cabeza, las vísceras y el tronco no cambian significativamente por el nivel de proteína en la dieta. Los contenidos más altos de proteína de los peces alimentados con dietas ricas en proteínas se deben a un aumento en el peso relativo del tronco (músculo) con respecto al peso corporal total.

Abstract

The object of the present study was to establish the relationship between the size an body segments in Colombian adult subjects, to get an equation that allows to estimate the size from those segments and confront it with those described in the literature.Group 1: Subjects over 18 years were chosen without deformities, amputations neither edemas. Age, sex, weight, size, forearm length (Fl), lower segment length (LSL), navel-heel length (NHL), navel-malleolus length (NML), lower member length (LML), knee height (KH), knee-external malleolus length (KML). Group 2: The same variables were quantified and to these subjects were established the accuracy and precision of the obtained equations and were confronted with those described in the literature. Statistical analysis. The gotten results were analyzed by means of the Student "t" test, correlation analysis, and simple linear regression and multiple step by step. An alpha error of 5% was accepted.189 subjects were evaluated in group 1 and 180 in group 2. 23 male and 156 female 37.5 +/- 17.5 years old and a size of 161.2 cm +/- 9.6 cm. There was a significant correlation (p0.0001) between size and all the measured segments. Predictive size regression equations were established choosing the following segments: FL, NML, KML, because of their easy determination, precise reference points and high "t". The estimated size was not significantly different from the real one just in those that use KML, age an sex: Male: Size = (KML x 1.21) - (0.117 x age) + 119.6. Female: Size = (KML x 1.263) - (0.159 x age) + 107.7. The equations described by Chumlea et al. using the KH just predict the size adequately in male, but overestimate it in female.1. The equations using the KML predict the size in the colombian studied sample. 2. The Chumlea equations only adequately predict the size of the male colombian subjects.
