“…Pacu fed low‐protein diets used dietary protein more efficiently, as reflected by the higher PER and PPV values recorded, than fish fed the high protein diets. In general, protein retention efficiency increases with low protein intake, as reported, for instance, by Vásquez‐Torres et al. (2002), Salhi et al.…”

Improper dietary protein and energy levels and their ratio will lead to increased fish production cost. This work evaluated effects of dietary protein : energy ratio on growth and body composition of pacu, Piaractus mesopotamicus. Fingerling pacu (15.5 ± 0.4 g) were fed twice a day for 10 weeks until apparent satiation with diets containing 220, 260, 300, 340 or 380 g kg−1 crude protein (CP) and 10.9, 11.7, 12.6, 13.4 or 14.2 MJ kg−1 digestible energy (DE) in a totally randomized experimental design, 5 × 5 factorial scheme (n = 3). Weight gain, specific growth rate increased and feed conversion ratio (FCR) decreased significantly (P < 0.05) when CP increased from 220 to 271, 268 and 281 g kg−1 respectively. Pacu was able to adjust feed consumption in a wide range of dietary DE concentration. Fish fed 260 CP diets showed best (P < 0.05) protein efficiency ratio and FCR with 11.7–12.6 MJ kg−1; but for the 380 CP‐diets group, significant differences were observed only at 14.2 MJ kg−1 dietary energy level, suggesting that pacu favours protein as energy source. DE was the chief influence on whole body chemical composition. Minimum dietary protein requirement of pacu is 270 g kg−1, with an optimum CP : DE of 22.2 g MJ−1.

“…También se evaluaron los seguintes ingredientes de origen animal: harinas pescado, de carne y huesos y de sangre. Como base de las dietas experimentales fue utilizada la dieta referencia semipurificada (DRS) desarrollada por Vásquez-Torres et al (2002). Para cada ingrediente investigado fue elaborada una dieta compuesta por 69.5% de DRS, 30% del ingrediente en estudio y 0,5% de marcador inerte (óxido de cromo) (Cuadro 1).…”

Resumen -El objetivo de esta investigación fue evaluar los coeficientes de digestibilidad aparente de materia seca (MS), proteína y energía de alimentos de origen animal y vegetal, utilizados en raciones para cachama (Piaractus brachypomus). Fueron formuladas 15 dietas experimentales, compuestas por 69,5% de una dieta referencia semipurificada, 0,5% de óxido de cromo y 30% del ingrediente a evaluar. En cada experimento, fueron utilizados 90 peces que se alimentaron durante cinco días con la correspondiente dieta; al quinto día, los animales fueron trasladados a tanques cónicos para recolección de heces. Los coeficientes de digestibilidad aparente (CDA) de proteína variaron de 92,1 a 84,7% entre los ingredientes proteicos de origen vegetal, de 85,0 a 68,5% en los proteicos de origen animal, y de 83,7 a 57,6% entre los de origen vegetal con baja proteína. Los CDA de energía de torta de soya, gluten de maíz, harina de yuca integral y de todos los ingredientes de origen animal arrojaron valores superiores a 76%. Los máximos CDA de MS variaron entre 71 y 78% y fueron observados en gluten, harina de yuca y en los ingredientes de origen animal. La cachama tiene alta capacidad para aprovechar eficientemente ingredientes de origen animal y vegetal.Términos para indexación: Piaractus brachypomus, coeficientes de digestibilidad, energía digestible, ingredientes alimenticios, peces tropicales, proteína digestible. Apparent digestibility of ingredients from plants and animals in cachamaAbstract -The objective of this work was to evaluate the apparent digestibility coefficients of dry matter (DM), protein and energy of ingredients from animals and plants utilized in the ration for cachama (Piaractus brachypomus). Fifteen experimental diets were formulated, which were composed by 69.5% of a semipurified reference diet, 0.5% chromium oxide, and 30% of the ingredient to be evaluated. In each experiment, 90 fish fed the corresponding diet were used; in the fifth day, fish were transferred to conical tanks for fecal sampling. The apparent digestibility coefficients (ADC) of protein varied between 92.1 and 84.7% among protein ingredients from plants, between 85.0 and 68.5% among protein ingredients from animals, and between 83.7 and 57.6% among low-protein ingredients from plants. Energy ADC of soybean meal, corn gluten, wholly yuca meal and of all ingredients from animals produced values higher than 76%. The highest values for CDA of DM varied between 71 and 78% and were observed in gluten, yuca meal and in ingredients from animals. Cachama has a high ability to efficiently benefit from ingredients from animals and plants.

“…Traditionally, wheat inclusion in prepared characid diets ranges from 5 to 35% (Roubach and Saint‐Paul 1994; Vásquez‐Torres et al 2002). We substituted 30% yucca, pijuayo, or plantain for wheat middlings or wheat bran in our study and obtained equal or better growth performance of red and black pacu fed the control diets.…”

To facilitate economical culture of black pacu, Colossoma macropomum, and red pacu, Piaractus brachypomus, in the Amazon region of South America, we assessed locally available alternative energy sources for practical diets. We tested the effects of control diets (containing wheat products) versus diets with different Amazonian feedstuffs (yucca, Manihot sculenta, plantain, Musa paradisiaca, or pijuayo, Bactris gasipaes) on the performance of the pacus in three feeding trials. Black pacu (22.5 6 0.03 g; Trial 1) or red pacu (2.56 6 0.01 g; Trial 2) were fed diets containing 30% wheat bran (control) or cooked or uncooked yucca, plantain, or pijuayo for 12 wk. In Trial 3, larger black pacu (86.9 6 6.4 g) were grown to market size in 24 wk on similar diets. Weight gain, feed conversion, survival, alternative complement activity, and lysozyme were similar among diets. Hepatosomatic index, liver glycogen, and dry matter were affected by diet in Trials 1 and 2, but effects were not consistent among trials. In Trial 3, protein efficiency ratio was lower in fish fed the diet containing wheat middlings. However, relative to wheat bran or wheat middlings, all feedstuffs tested were effective energy sources for juvenile black pacu and red pacu.
