Sacha Inchi

Antecedentes: El cultivo de Sacha Inchi (P. volubilis) viene siendo desarrollado en la selva amazónica peruana y en Colombia se cultiva principalmente en el departamento del Putumayo. Hoy en día existen propuestas de su implementación en la región del Catatumbo Norte Santandereano. Objetivo: En este estudio se evaluó el efecto de la inclusión de Torta de Sacha Inchi (TSI) (Plukenetia volubilis), como fuente de proteína en dietas para juveniles de tilapia roja (Oreochromis sp.). Metodología: Fueron preparadas cuatro dietas experimentales en las cuales se incluyó la TSI, como sustituto parcial de la harina de pescado en los siguientes porcentajes 0%, 5%, 10% y 20%. Fueron utilizados 144 juveniles de tilapia con peso inicial de 5,8 ± 0,9 g, los cuales fueron alimentados con ocho raciones diarias durante 55 días para evaluar: ganancia de peso (GP), conversión alimenticia (CA), tasa específica de crecimiento (TEC), tasa de eficiencia proteica (TEP), índice hepatosomático (IHS) y porcentaje de sobrevivencia (%S). Resultados: Los resultados no evidenciaron diferencias significativas (p>0,05) en ninguna de las dietas para CA y %S. Sin embargo, los parámetros: GP, TEC, TEP y IHS presentaron valores significativamente elevados para inclusiones de 0, 5 y 10%, difiriendo estadísticamente (p<0,01) del nivel inclusión de 20%. Conclusión: Se concluye que P. volubilis puede sustituir la harina de pescado hasta en un nivel de 10% de inclusión. Abstract Background:The cultivation of Sacha Inchi (P. volubilis) has been developed in the Peruvian Amazon and in Colombia is grown mainly in the Department of Putumayo. There are proposals nowadays for implementation of this crop in the Catatumbo region (Norte de Santander). Objective: This study assessed the effect of Sacha Inchi cake (SIC) (Plukenetia volubilis) inclusion as a source of protein in diets for juveniles of red tilapia (Oreochromis sp). Methodology: four experimental diets including SIC as a partial substitute of fishmeal were prepared in the following percentages: 0%, 5%, 10% and 20%. 144 juvenile tilapia with initial weight of 5.8 ± 0.9 g were used, being fed with eight daily rations during 55 days to assess: weight gain (WG), feed conversion (FC), specific growth rate (SGR), protein efficiency ratio (PER), hepatosomatic index (HI) and survival rate (%S). Results: The results showed no significant differences (p> 0.05) in any of the diets for FC and %S. However, the parameters: WG, SGR, PER and HI had significantly higher values for inclusions of 0,5 and 10%, being statistically different (p <0.01) from the 20% inclusion level. Conclusion: It is concluded that P. volubilis can replace fish meal up to a 10% level of inclusionPalabras clave: Harina de pescado, Índice hepatosomático, Nutrición de peces, Piscicultura, Sobrevivencia.

Abstract Waste non-standard fish combined with wheat bran filler in ratio 60:40 were used for production of new non-traditional protein component called Ribotricin. The aim of this study was to elucidate the effects of the new protein component Ribotricin on growth performance, feed utilization and feed ingredients digestibility of carp (Cyprinus carpio L., 1758) fish. The experiment (90 days) involved 160 carp reared in eight concrete tanks with an initial average weight of 0.046 ± 8.04 g in (RT) tank, and fish with an initial average weight of 0.047 ± 6.52 g in (FM) tanks. The experimental carp were equally divided into two groups of 80 (four replicates of 20 carp each). The obtained results at the end of the experiment, showed no significant differences between the groups` Body Weight (BW), Feed Conversion Ratio (FCR), Specific Growth Rate (SGR), Protein Efficiency Ratio (PER) (p> 0.05). Based on the obtained data, we can conclude that Ribotricin (RT) can be used as fish meal substitution in the diets of carp fish without adverse effects on the measured parameters.

Nursery evaluation of catla spawn was carried out by feeding three iso-nitrogenous diets (35% protein in raw and cooked form) for a period of 30 days. The three test diets (treatments) in raw form were: T1 - groundnut oil cake (GOC) + rice bran (RB) + vitamin-mineral (V-M) premix; T2 - GOC+RB+fish meal (FM) + V-M premix, T3 - GOC+RB+prawn meal (PM)+V-M premix. The diet groups GT1, GT2 and GT3 respectively were same feed combinations in cooked form. Incorporation of prawn meal as animal protein source led to significantly higher final weight, final length, % weight gain, specific growth rate (SGR) and protein efficiency ratio (PER) compared to diet with and without fish meal incorporation. Whereas, diet containing fish meal improved the fry growth and survival rate only when it was cooked. Cooked diet either with fish or prawn meal incorporation led to better fry growth over the respective non-cooked diets, revealing the advantage of cooking process for better nourishment in catla fry during nursery phase.

The effects were studied of using combinations of plant protein sources, GNC, Palm Kernel cake, and cotton and seed cake diets, supplemented with 4 sources of methionine (M) and Lysine (L), synthetic M+L, blood meal + M, fish meal, or chicken offal meal (COM) in 8-Week 3 x 4 factorial experiment with starter cockerels. Sources of M and L did not affect mean daily gain of the birds but significant differences (P<0.05) were observed in feed intake, feed per gain ratio, protein efficiency ratio (PER), nitrogen retention (NR) as well as economy of feed conversion. Maximum weight, best feed conversion ratio, PER and economy of feed conversion were observed in the M+L dietary group followed by those on blood meal + M supplementary group where maximum NR was observed. The least response values (except NR) were obtained in the COM group. This study indicated that starter cockerels (0-8 weeks) fed diets supplemented with synthetic methionine and lysine gave the most optional performance.

Fish is used as a great source of food and the quality of its meat can be indicated by fat and protein contents as well as low quantity of water in fish meat. Therefore, the present study was performed for improvement in weight, feed-conversion ratio, protein-efficiency ratio, and growth. The experiment was performed at commercial level in field (pond) and the influence of fish meal protein on growth of Labeo rohita was investigated in 60 days culture trials. 90 fingerlings (Size: 4.97 to 6.04; Weight: 4.15 to 4.20) were maintained in well aerated 280 L three glass tanks in triplicate. These glass tanks were named as T1, T2 and T3. T1 was consisted of 30% crude protein with control diet containing proteins, fats vitamins and fibres, T2 consisted of 35% protein with control diet, while T3 consisted of only control diet (rice polish). The fish were fed 4% percent of their body weight twice a day at twelve hours interval for 60 days. There was a significant increase (p<0.05) in body weight, feed-conversion ratio, protein-efficiency ratio, and gross fish production of fish having 35% fish meal protein with control diet (T2) when compared with 30% fish meal protein with control diet T1 and control diet T3. These findings suggest that 35% fishmeal protein appear to be sufficient for obtaining optimum growth in fish.

Monodora Myristica

Fungal infected feedstuffs are denatured in nutrients and cause them to develop off flavors that often dampen the appetite of livestock and poultry. In this study, the effect of toasted African nutmeg (Monodora myristica) spice in Aspergillus flavus-infested diets on growth performance of broilers was investigated in a 2 x 3 factorial experimentthat lasted for 42 days. Three out of 6 dietary treatments were infected with 1mg of pure culture of Aspergillus flavus and toasted Monodora myristica spice included at 0%, 0.5% and 1.0% while the other 3 diets were infection-free with 0%, 0.5% and 1.0% Monodora myristica inclusion respectively. Each treatment was replicated three times at 30 chickens per replicate. Infection status was significant (P<0.05) for daily weight gain, feed conversion ratio (FCR) and protein efficiency ratio (PER). Daily weight gain, feed conversion ratio and protein efficiency ratio were 134.19g/bird/day, 39.23g/bird/day, 3.59g/bird/day and 1.10g/bird/day, respectively for the non-infected diets. The aflatoxin infection from Aspergillus flavus was observed to reduce (P<0.05) feed intake to 130.51g/bird/day and weight gain (33.67g/bird/day). FCR and PER were also reduced (P<0.05) by the presence of aflatoxin from Aspergillus flavus in the diet. Effect of Monodora myristica supplementation on feed intake, average daily weight gain, FCR and Protein efficiency ratio was significant (P<0.05) for all the measured parameters. The Feed intake, average daily weight gain, FCR and protein efficiency increased (P<0.05) as Monodora myristica inclusion level increased. Feed intake (119.8g/b/d), daily weight gain (28.90g/b/d), FCR (4.28) and PER (0.94) were observed in the Monodora-free (0%) diet. 0.5% and 1.0% levels of Monodora inclusion produced similar (P>0.05) effects on all the growth parameters but were higher than the control. The interaction of aflatoxin infection and Monodora inclusion level were significant for all the growth parameters. The interaction of aflatoxin infection x Monodora inclusion levels recorded feed intake of 107.97g/b/d, 137.36 and 146.19g/b/d respectively for 0, 0.5 and 1.0% Monodora; 22.27g/b/d, 37.87g/b/d and 40.83g/b/d daily weight gain and 4.85%, 3.63% and 3.58% FCR. The interaction effect of Monodora inclusion level in infection-free diets on the birds feed intake were 131.65g/b/d, 147.24g/b/d and 123.67g/b/d respectively for 0%, 0.5% and 1.0%. The interaction effect at 0.5% inclusion level x non-infected diet was significantly higher (41.31g/b/d) than that at 0% inclusion level on daily gain. However, the daily weight gain of 40.83g/b/d observed in the interaction of 1.0% Monodora level x aflatoxin -free diet similar (P<0.05) to that observed in the 0.5% inclusion level. The feed conversion ratio produced by the interactions at the three different levels (0, 0.5 and 1.0%) in the Aspergillus-free diets were (P>0.05) 3.71, 3.57 and 3.49 respectively while PER were (P<0.05) 1.05, 1.13 and 1.11 respectively. The Monodorafree diet recorded 9.26% drumstick, 2.26% liver 0.65% kidney and 2.43% gizzard, while the diet that had 0.5% Monodora myristica yielded 2.12% liver and 2.29% gizzard. Inclusion of Monodora up to 1.0% recorded 1.63% liver weight. Aspergillus flavus alone caused a reduction in live weight, dressed weight, thigh, kidney, breast meat, gizzard and an enlargement in the liver. Monodora myristica inclusion level also affected (p<0.05) all the parameters except dressed weight, thigh and back cut. Kidney and liver were observed to decrease as the level of inclusion of Monodora myristica increased. The interaction of Monodora myristica and Aspergillus flavus on the parameters were significant (p<0.05). From the results, Monodora myristica may be beneficial to poultry farmers, since about 90% of the poultry feed ingredients especially grains are constantly exposed to aflatoxin infection from Aspergillus flavus and other mycotoxin infections which hinder maximum nutrient utilization and affect the rate of conversion of feed.

The study was undertaken to examine the capability of carbohydrate to spare protein in the diet of fringed lipped carp, Labeo fimbriatus (2.93 g±0.15). Three semi-purified experimental diets of iso-caloric nature were formulated having three graded levels of protein (27, 23 and 19% CP) and three levels of carbohydrate (26, 31.5 and 37% CHO). Accordingly, the treatments were designated as T1 (27% CP and 26% CHO), T2 (23% CP and 31.5% CHO) and T3 (19% CP and 37% CHO), where the experimental diet T1 served as the reference diet. The fish were reared in 200 l fibre reinforced plastic (FRP) tanks under continuous aeration with one third water exchanged daily. After 90 days of feeding trial, it was noticed that the percentage weight gain and specific growth rate (SGR) of 27% protein fed group (209.5±0.74% and 1.26±0.15%) and 23% protein fed group (204.8±0.52% and 1.24±0.13%) were not significantly different (p>0.05). Similarly, the results of feed performance like feed conversion ratio (FCR) among 27% protein fed group (2.24±0.11) and 23% protein fed group (2.29±0.14) did not vary significantly (p>0.05). On the other hand, the protein efficiency ratio (PER) and protein productive value (PPV) of 23% protein fed group (1.87±0.11 and 28.34±0.36) did not vary significantly (p>0.05) with the 19% protein fed group (1.93±0.12 and 27.65±0.32). The carcass protein (CP) and lipid (as ether extract,EE) content of 27% protein fed group and 23% protein fed group were not significantly different (p>0.05). Results of this study indicate that the CP level in the diet of fringed-lipped carp L. fimbriatus can be reduced from 27 to 23% by proportionately increasing carbohydrate level from 26 to 31.5% without compromising growth and also without any adverse physiological effect.

Siamese catfish (Pangasius hypophthalmus) at juvenile stage is used as ornamental fish by fish hobbies because of their beautiful shape and movement. Feeding time is a part of feeding management to get the best and effective strategy on feed input. This study aimed to determine the growth of Siamese catfish juvenile by looking at the influence of feeding time on feed utilization. The average individual weight of juveniles used was ± 3.2 g stocked 15 fish per aquarium equipped with recirculation system. Two level factors in the factorial design consisted of 4 feeding times (at 8:00, at 12:00, at 16:00, and as control (8:00, 12:00, 16:00) and feeding level (45 g feed kg-1 fish, 90 g feed kg-1 fish). Interaction between feeding time and feeding level resulting eight types of treatments research, namely A (8/45), B (12/45), C (16/45), D (8:12:16/45), E (8:12:16/90), F (8/90), G (12/90), and H (16/90). The results showed that feeding time had significant effect on the specific growth rate, feed conversion, and protein efficiency ratio and were significantly different among the treatments (P<0.05). Besides feeding time control (treatments D and E), treatment C also showed the highest of specific growth rate (2.03%), protein efficiency ratio (1.46), and the lowest feed conversion ratio (1.85).

An eight-week feeding trial was conducted to evaluate the growth performance characteristics of (120) broiler starter fed varying levels of parboiled sundried taro cocoyam (Colocasia esculenta) meal (PSCM). Four treatments were formulated with diet one containing 100% maize as control, while in diet two, three and four parboiled sundried cocoyam meal (PSCM) replaced the percentage proportion of maize in diet one at 50, 75 and 100% inclusion level respectively. Thirty (30) birds were randomly assigned to the four treatment diets in a completely randomize designed (CRD) each treatment group comprising of three replicates with ten (10) birds each. Growth performance revealed a significant variation (P<0.05) in the values of final live weight, daily feed intake and weight gain with highest value (1.62kg, 480.00g and 62.00g/bird) among those fed 50% PSCM. Feed conversion ratio (13.02) was least and best among those on 50% PSCM and protein efficiency ratio was higher (0.06) among those fed the control. It is concluded therefore from this study that parboiled sundried taro cocoyam meal is a valuable replacement for maize up to 50% in broiler diets without adverse effects on the growth performance of starting broiler chickens.
