“…Incidence cost (IC) was the cost of feed used to produce a kg of fish (relative cost per unit weight gain) and the lower the value, the more profitable using that particular feed (Nwanna, 2003;Abu, Sanni, Erondu, & Akinrotimi, 2010). IC = Cost of feed/weight of fish produced (6) (2) Profit Index…”

A 100 days experiment was conducted to determine the effect of feeding blood meal (BM) as a replacement of fish meal (FM), as the main source of animal protein, on growth rate and economic performance of Nile tilapia in fertilized pond. Three isonitrogenous diets (35% crude protein) were formulated using either FM as the main source of animal protein (Diet 1); 50% replacement of FM with blood meal (Diet 2); or 100% replacement of FM with BM (Diet 3). Three hundred Nile tilapia fingerlings (12±3 g) were randomly distributed into three groups of four replicates of 25 fingerlings per cage. The groups were randomly assigned the 3 diets which were fed at 2% of their biomass at 10 am and 4 pm every day. Percentage daily weight gain (DWG), relative growth rate (RGR), specific growth rate (SGR), survival rate and feed utilisation efficiency were measured. Fish fed diet 1 were larger (50.69 g) (P < 0.05) than those fed diet 2 (48.47 g) and 3 (40.37 g). Replacement of FM with 50% and 100% BM reduced the incidence cost (45.55, 37.83 and 31.88, respectively). The profit index was highest with 100% (9.42) replacement of FM, compared to 50% (7.95) and 0% (6.69). Although replacing FM with BM was associated with reduced growth, the economic return was better (P < 0.05). Based on the present results, it was economical to use BM as a major protein source instead of FM in formulating fish feed.

“…On the contrary, Diet 4 (groundnut bran-based diet) was the most expensive in terms of IC in the current study. The variance in results might be because, Diet 4, was prepared with FM as the major source of protein which in itself is expensive (Falaye and Jauncey, 1999;Abu et al, 2010). Coupled with that, the poor performance of the fish fed on Diet 4, did not compensate for the rather high cost of feed in this study.…”

“…The high cost of feeding has affected the development and expansion of aquaculture enterprises in most African countries contributing in no small way, to the low protein intake in many developing African countries (Abu et al, 2010). Non conventional feed resources are credited for being non competitive in terms of human consumption, very cheap by-products or waste products from agriculture, (IIuyemi et al, 2010).…”

. They were fed to fingerlings of O. niloticus of average weight 7.0 ± 0.23 g stocked at 20 fish m -3 in out-door hapas for a period of 24 weeks. The study revealed that fish which were fed on Diet 1 grew significantly (P < 0.05) faster than those fed on the other diets. Fish growth was least on those fed on Diet 4. The incidence cost (IC) was highest (P < 0.05) in fish fed Diet 4 and lowest (P < 0.05) for fish fed Diet 2. The profit index was highest (P < 0.05) for fish fed diet 2 and lowest (P < 0.05) for fish fed Diet 2. O. niloticus fingerlings fed WB based diet produced the fastest growth while fingerlings fed PM based diet was the most cost-effective diet.

“…A clear example of that is the study performed by Abu et al (2010) in which, they found that CRM can effectively replace corn as a dietary source of energy in low-cost aquafeeds for hybrid African catfish Clarius gariepinus. Complementarily, Udo & Umoren (2011) found that boiled CRM is well digested by the same catfish as ADC values for dry matter, crude protein and energy were 88.5, 94.4, and 73.2% in that species.…”

COEFFICIENTS OF ENERGY AND NUTRIENT APPARENT DIGESTIBILITY OF THREE RAW AND COOKED ALTERNATIVE PLANT INGREDIENTS FOR Colossoma macropomum AND Piaractus brachypomus (SERRASALMIDAE)

et al. 2016

The coefficients of the apparent digestibility for dry matter, crude protein, crude lipid and gross energy in cooked and raw green plantain meal (GPM), cassava root meal (CRM), and peach palm meal (PPM) were determined for juveniles of black pacu (60.8 ± 6.4 g) and red pacu (76.3 ± 5.0 g). The ADC of each alternative ingredient was determined by comparison of the digestibility (based on recovery of 1% chromic oxide as an inert marker) of a reference diet (consisting of 70% of test diet and 30% of the feedstuff) against with a test diet (24.5% of crude protein). Fish were bred in a recirculation system including 42, 110-L glass aquaria (21 tanks per species) at a density of five fish per tank, and fed their respective diets to apparent satiety, twice a day. Feces were collected after 10 days in plexiglass fecal collectors. Apparent digestibility coefficients of crude protein, crude lipid and gross energy from raw and cooked GPM and CRM were low compared to values to other common vegetal ingredients like corn and wheat. Conversely, ADC values for raw and cooked PPM were, in most cases, higher than those reported in raw or cooked GPM and CRM. In comparison with other traditional feedstuffs, apparent utilization of PPM was similar to corn and higher than reported for soybean meal and wheat bran in these fish species. Peach palm meal appears to have good potential as a feed ingredient in low-cost diets for pacu species.KEYWORDS: aquaculture, digestibility, feeding, red pacu, black pacu. COEFICIENTES DE DIGESTIBILIDAD APARENTE DE LOS NUTRIENTES Y LA ENERGÍA DE TRES INGREDIENTES VEGETALES ALTERNATIVOS CRUDOS Y COCIDOS EN Colossoma macropomum Y Piaractus brachypomus (SERRASALMIDAE) RESUMENLos coeficientes de digestibilidad aparente (ADC) para la materia seca, proteína cruda, lípidos y energía bruta en harinas obtenidas de porciones crudas y cocidas de plátano verde (GPM), yuca (CRM) y pijuayo (PPM) fueron determinados en juveniles de gamitana (60.8 ± 6.4 g) y paco (76.3 ± 5.0 g). El ADC de los ingredientes alternativos fue determinado por comparación de la digestibilidad (basada en la recuperación de óxido crómico como marcador inerte) de una dieta referencial (70% de dieta testigo y 30% del ingrediente en estudio) versus la dieta testigo (24.5% de proteína bruta). Los peces fueron criados en un sistema de recirculación compuesto de 42 acuarios de vidrio de 110 L (21 tanques para cada especie), a una densidad de cinco peces por tanque y alimentados con sus respectivas dietas hasta la saciedad aparente, dos veces por día. Las heces fueron colectadas a los 10 días en colectores fecales. Los niveles de ADC para proteína bruta, lípidos y energía bruta registrados para las harinas crudas y cocidas de plátano y yuca fueron bajas comparadas con las existentes para otros ingredientes como el maíz y el trigo. Sin embargo, los niveles de ADC obtenidos para las harinas crudas y cocidas del pijuayo fueron en la mayoría de los casos superiores a los reportados para el plátano y la yuca. En comparación con otros ingredientes ...
