ABSTRACT Sacha inchi (Plukenetia volubilis) is a plant native to the Peruvian Amazon with seeds that contain 24 to 29% protein, and levels of vitamin A and E and omega 3 polyunsaturated fatty acids that are suitable for fish nutrition. Thus, this study aimed to evaluate the use of sacha inchi seeds as an ingredient in the diets of tambaqui (Colossoma macropomum) and matrinxã (Brycon amazonicus). The acceptance and effect of three levels of sacha inchi seed meal (0, 15 and 30%) in fish feed was evaluated in a randomized experiment, testing groups of 12 juvenile tambaquis (29.8 ± 1.0 g, 11.0 ± 1.4 cm) and groups of eight juvenile matrinxãs (34.8 ± 1.3 g, 13.7 ± 1.0 cm). Growth performance and body composition of the fish were determined at the end of the experiment. An effect of the sacha inchi diet was only observed for feed conversion of tambaquis, which was worst at the highest level of sacha inchi seed. In conclusion, sacha inchi can be added to feed juvenile tambaquis at a level of 15%, and juvenile matrinxãs at 30% without compromising growth performance and body parameters of the fish.

Sacha Inchi

La presente investigación tiene como propósito de estudio desarrollar estrategias viables para posicionar y comercializar el Sacha Inchi y sus derivados en el mercado de la gran Lima. El Sacha Inchi es una planta nativa de la Amazonía peruana, descrita por primera vez como especie en el año 1753 por el naturalista Linneo, de ahí su nombre científico Plukenetia volúbilis linneo. En el Perú se conoce de su existencia desde el incanato. Así, hasta nuestros días, ha tomado diferentes nombres: Sacha Inchic, palabra quechua que significa maní del monte o silvestre; Amui, término utilizado por las tribus aborígenes de la amazonía; Sacha Inchi, maní del monte, maní del Inca e Inca peanut. En la actualidad, conocida también como el maní de los Incas, es la oleaginosa natural con mayor contenido de omega, un ácido graso esencial para la vida del ser humano. Está compuesto de 48.60% de ácido graso esencial alfa linolenico (Omega 3), 36.80% de ácido graso esencial linoleico (Omega 6) y 8.28% de ácido oleico (Omega 9). Además tiene el más bajo contenido de ácidos grasos saturados: 6.39% en promedio, 3.85% de palmítico y 2.54% de esteárico. Actualmente el Sacha Inchi se comercializa, en su mayor porcentaje, en la forma básica; vale decir, granos tostados (similar al maní) que facilmente se encuentran en la mayoría de las tiendas naturistas, en tanto que en autoservicios se comercializa el aceite, que en su fase de industrialización está dirigido a un segmento pequeño y selectivo de la población limeña. La investigación revela tambien que se pueden fabricar y comercializar otros productos hechos sobre la base del Sacha Inchi. Así, las opciones de su comercialización van desde el inchicapi, ají de sacha inchi, cutacho, mantequilla de sacha inchi, inchi cucho, tamal de sacha inchi, turrón, snacks, entre otros; rubros en los cuales la ciudad de Lima todavía es un mercado cautivo por madurar. En todas ellas, las estrategias de promoción y publicidad deben resaltar las propiedades nutritivas e incluso curativas del Sacha Inchi. Al respecto, la investigación de fuentes secundarias revela que el consumo frecuente de esta oleaginosa reduce la obesidad y favorece los tratamientos contra el cáncer, diabetes, enfermedades del corazón, presión arterial, disfunción eréctil y estrés. Incluso hay una investigación que postula que el Sacha Inchi previene el Alzheimer, mejora la visión, mejora el desarrollo infantil, refuerza la concentración mental y fortalece el sistema inmunológico.

The objective of this study was to investigate the effects of enriched omega-3 oil supplemental pellets, breed and gender on lamb liveweight (LWT), body conformation and carcass characteristics, and to assess the relationships between body conformation and growth under an intensive finishing condition. Sixty ewe and wether prime lambs 7 months old were randomly allocated to one of five dietary treatments: no oil inclusion (Control); 2.5% canola oil; 5% canola oil; 2.5% flaxseed oil and 5% flaxseed oil, balanced by breed (purebred Merinos (M × M) and Corriedale × Merino (C × M) and White Suffolk × Corriedale (W × C) first crosses). Lambs were individually supplemented with 1 kg pellets per day and had free access to lucerne hay and water throughout the 7-week feeding trial, after a 3-week adaptation. Dietary oil inclusion did not cause significant differences in daily feed intake, growth performance and carcass characteristics (P > 0.05). However, first-cross W × C lambs had significantly higher feed intake, chest girth and body conformation score (P < 0.05) than M × M and C × M lambs. Carcass weight, dressing percentage and fat depth of crossbred lambs were significantly higher than those of M × M (P < 0.05). Significant interactions between oil inclusion and breed on average daily gain (ADG) and feed conversion ratio were observed. There were positive and highly significant correlations among LWT, ADG and body conformation measurements (P < 0.01). These findings suggest that prime lamb producers can better manage and match their breeding goals with feed resources by supplementing first-cross C × M lambs with pellets containing 5% canola oil or feeding first-cross W × C lambs with 5% flaxseed oil pellets during the 10-week intensive finishing period.

Background: Fat and oil are commonly used in poultry diets to increase energy density and also to increase the palatability of feed, feed efficiency and for deposition of fat in broilers. Thus a study was proposed to find the effects of dietary replacement of saturated fatty acid rich palm oil (PO) by omega-3 rich rapeseed oil (RO) on growth performance and economics in broilers. Method: The growth performance feeding trial was conducted in 160 day-old broilers (vencobb 400) with four treatment groups (G1, G2, G3 and G4) with four replicates of ten chicks each. The basal diet (R1) was prepared with palm oil included at the rate of 1.5, 3, and 4.5 per cent in pre-starter, starter and finisher ration, respectively and fed to G1. The other treatment groups G2, G3 and G4 received R2, R3 and R4 experimental rations respectively. The experimental rations R2, R3 and R4 were prepared with rapeseed oil replacing 25, 50 and 100 per cent of palm oil which was included in R1. Result: The broiler ration prepared with rapeseed oil at 50 and 100 per cent level (G3 and G4) replacing palm oil showed increased body weight gain (P less than 0.01) and better feed conversion ratio (P less than 0.05) than G1 group. There was no significant difference in the feed intake among the different treatment groups. Profit per kg live weight in G3 (Rs.12.06) and G4 (Rs.11.14) was more than G1 (Rs.8.21) and G2 (Rs.6.57). The supplementation of omega-3 rich rapeseed oil had significantly improved the performance of broilers.

A comparative study on the growth performance of African catfish (Clarias gariepinus) fed shrimp based diet (SBD), chicken offal based diet (COBD) and coppens feed was carried-out for 22 weeks in concrete tanks measuring 3.5 x 1.7 x 1.5 m3. Triplicate groups of 40 juveniles with average length of 9.15 ± 0.17cm and weight of 20.00 ± 2.58g were stored in each tank. A total of 360 juveniles were used throughout the study. Fish were fed daily at 3% of their body weight through-out the duration of the experiment. The nutrient composition of the 3 nutrients differed significantly at p<0.05. Weight gain (WG) (g) was highest (17189.33 ± 506.61g) in fish fed diet A (Coppens feed), followed by 15045.33±202.42 g (diet B) (SBD) and least (14357.33 ± 108.25 g) (diet C) (COBD). The Growth rate (GR) was highest in fish fed with diet A (111.62 ± 3.29 g/day), followed by 97.69±1.31 g/day (diet B), and least (93.23±0.70 g/day) in diet C. Specific growth rate (SGR) was highest in juveniles fed diet A (2.02 ± 0.02 %/day), followed by 1.94±0.01 %/day for diet B, and least (1.91±0.01 %/day) for diet C. Mean growth rate (MGR) was highest in juveniles fed diet A (11.88 ± 0.29 mg/day), followed by 11.74±0.15 mg/day for diet B, and least (11.69±0.09 mg/day) in fish fed diet C. The WG, GR and SGR varied significantly between the juvenile fish group fed the 3 diets at p<0.05, while MGR did not vary significantly between fish group fed the 3 diets at p>0.05. Fish fed diet A had a higher feed consumption (FC) (41650.00 ± 315.34 g/kg), than that fed diet B (39034.24 ± 86.34 g/kg) and then diet C (38276.00 ± 342.97 g/kg). Juveniles fed Coppens feed did better, with a feed conversion ratio (FCR) of 2.42 ± 0.06, followed by 2.59±0.04 for diet B and 2.67 ± 0.03 for fish fed diet C. Feed conversion efficiency (FCE) was higher in fish fed diet A (41.26±0.94 %), followed by 38.54 ± 0.54 % (diet B) and least (37.52 ± 0.51 %) (diet C). The FC and FCR varied significantly between the fish fed the 3 diets at p<0.05, while FCE was not significantly different between the 3 treatment groups at p>0.05. The water parameters of the culture water varied significantly between each treatment groups (p<0.05), and were within the rage suitable for normal growth of fish. Though coppens feed yielded better growth performance and feed utilisation, the use of COBD and SBD is recommended for fish farmers in Nigeria. More researches should be carried out on using chicken offals and shrimps in fish feed formulation.

Abstract: Sacha inchi (Plukenetia volubilis L.) is an Amazon species of elevated agro-industrial potential due the high content of omega-3 and omega-6 in its seeds. Despite of it, little information about its propagation by seeds is currently available. Thus, the aim of this study was to assess seed germination, seedling survival and growth of this species under different conditions of substrate (on paper, between papers and paper roll), light (continuous darkness, 12-h photoperiod and continuous light) and temperature (continuous temperature at 20, 25, 30, 35 and 40 °C). Germination is stimulated by substrates with increased surface contact with the seeds, presence of light and temperatures between 25 and 35 °C. Survival and initial growth of seedlings are favored by vermiculite, continuous light and 30 °C temperature. These conditions allow rapid and uniform germination of seeds and better establishment and development of seedlings. We encourage the propagation of sacha inchi by seeds, since we consider it a feasible technique.

Thai pangus polyculture with carps has been increasing for its high potential, however very few attempts were made to compare its growth using different types of feed. A research was undertaken to assess the effect of three types of feed on growth of Thai pangus (Pangasius hypophthalmus) and rohu (Labeo rohita) in polyculture system for 11 months from 15 May 2005 to 15 April 2006 in Khulna. Growth performance using Hand-made Feed (F1) was compared with two commercial fish feed, Sunney Feed (F2) and Saudi-Bangla Feed (F3) in three respective treatments of T1, T2 and T3. All treatments were carried out in triplicate at 24700/ha for Thai pangus and 4940/ha for rohu. Average initial weight of Thai pangus and rohu were 4.5 and 33.5g respectively. Growth performance was influenced by feed type. Average final weight of Thai pangus and rohu were 820 and 710; 846 and 770; and 872 and 717g with specific growth rate 1.58 and 0.93; 1.59 and 0.95 and 1.60 and 0.93 % day -1 in T1, T2 and T3 respectively. Feed conversion ratio was estimated 2.3 in T1, 2.1 in T2 and 1.96 in T3. The result showed a typical increasing trend of final weight and specific growth rate of Thai pangus along with the increasing of feed protein level. But rohu showed highest growth in T2 where protein level was 26-30% which was lower than that of T3 (Protein level 28-32%). The study suggests that suitable protein level and quality feed is required for adequate growth of fish.

Asian watergrass (Hygroryza aristata) is an herbaceous glabrous aquatic-rooted floating grass naturally growing in the tidally inundated coastal marshes, beels and canals. The ecology and growth performance of Asian watergrass were evaluated in the coastal wetland (CWL), in an artificially created canal (ACC) within the coastal wetland and in the university research ponds (URP). The study was conducted with three replications in each area. The proximate compositions of the leaves, roots and stems of the grass were determined. Important water and soil quality parameters were found favorable for the growth and production of Asian watergrass. The growth performance and total production of the grass were significantly higher in ACC (length: 2.78 m and weight: 386.86 metric ton ha−1) in comparison with those in CWL (2.36 m and 256.67 metric ton ha−1) and URP (2.22 m and 137.10 metric ton ha−1). Higher content of crude protein was found in leaves (17.49%) followed by roots (12.17%) and stems (9.39%), while the minerals (ash) and fiber contents were found higher in stems (25.68% and 9.53%) in comparison with those in leaves and roots. The findings indicate that the coastal wetlands of Bangladesh having available nutrients in both water and soil are suitable for higher growth and production of Asian watergrass. Considering the nutrient compositions, the Asian watergrass may be an important potential source of feed ingredient that may be used as fish feed in aquaculture throughout the world.

Introducción: La lipemia posprandial es un factor de riesgo coronario. Existe evidencia que los ácidos omega 3 disminuyen los lípidos plasmáticos. La Plukenetia volubilis Linneo, ‘sacha inchi’, es rica en omega 3. Objetivo: Determinar el efecto de la ingesta de sacha inchi sobre la trigliceridemia posprandial, en adultos jóvenes. Diseño: Estudio cuasi-experimental. Lugar: Facultad de Medicina, Universidad Nacional de Trujillo. Participantes: Estudiantes de medicina. Intervenciones: A doce estudiantes de medicina seleccionados al azar se les aplicó la prueba de tolerancia a triglicéridos, en dos fases: en la primera, después de la ingesta de 82 gramos de aceite de oliva y, en la segunda, adicionando 50 gramos de sacha inchi. Principales medidas de resultados: Efecto reductor de los lípidos plasmáticos. Resultados: En la primera fase, los triglicéridos basales fueron 99,67 mg/dL en promedio y luego se incrementaron en promedio 32 a la 1½ h, 74 a las 3 h, 89 a las 4½ h y 54 a las 6 h. En la segunda fase, el promedio basal fue 100,92 mg/dL, incrementándose 15 a la 1½ h, 52 a las 3 h, 40 a las 4½ h y 43 a las 6 h, en promedio, siendo significativa la reducción a la 1½ h (p=0,0232) y a las 4½ h (p=0,0496). Al graficar la prueba de tolerancia a triglicéridos, se evidenció significancia estadística al comparar el área bajo la curva de ambas fases (p=0,0080). Conclusiones: El consumo de la Plukenetia volubilis Linneo disminuye la trigliceridemia posprandial en adultos jóvenes.
