“…The higher digestible energy content observed in the present study would be caused by the ether extract content. When evaluating alternative feeds for Australian silver perch (Bidyanus bidyanus) using two MBMs with 49.20 and 54.30% of crude protein, Allan et al (2000) obtained ADC values of gross energy of 75.20 and 80.80% respectively, which were lower than the values obtained with tilapia, in the present work, when considering the chemical composition of the tested ingredients. The t test established differences between the values obtained and estimated for the meat and bone meals.…”

ABSTRACT. The objective of this study was to formulate a mathematical model to estimate digestible energy in animal feeds for tilapia. Literature results were used of the proximate composition of crude protein, ether extract, mineral matter and gross energy, as well as digestible energy obtained in biological assays. The data were subjected to stepwise backward multiple linear regression. Path analysis was performed to measure the direct and indirect effects of each independent variable on the dependent one. To validate the model, data from independent studies and values obtained from a digestibility trial with juvenile Nile tilapia testing five meat and bone meals (MBM) were used, using the Guelph feces collecting system and chromium oxide (III) as an indicator. The obtained model is described below and cannot estimate digestible energy (DE) of animal origin:The path coefficients were medium or low, the highest direct effect was from gross energy (0.529), while the highest indirect effect was from crude protein, through gross energy (0.439).Keywords: nutrition, nutritional value, estimate, linear models.Modelagem matemática para energia digestivel de ingredientes de origem animal para tilápias RESUMO. O objetivo deste estudo foi a formulação de equações para estimar a energia digestível em alimentos para a tilápia. Foram utilizados valores obtidos na literatura da composição centesimal em proteína bruta, extrato etéreo, matéria mineral e energia bruta (variáveis independentes), bem como a energia digestível (variável dependente) obtidos em ensaios biológicos. Os dados foram submetidos à regressão linear múltipla "stepwise backward". Foi realizada análise de trilha para medir os efeitos diretos e indiretos de cada variável independente sobre a dependente. Para validar o modelo foram utilizados dados de estudos independentes, e os valores obtidos em um ensaio de digestibilidade com juvenis de tilápia do Nilo, testando-se cinco farinhas de carne e ossos (FCO), utilizando o sistema de coleta de fezes de Guelph e óxido de cromo (III) como indicador. A equação obtida não pode estimar os valores de energia digestível (ED) de origem animal e está descrito a seguir:Os coeficientes de trilha obtidos tem valores de médios a baixo, sendo o maior efeito direto o da energia bruta (0,529), enquanto a proteina bruta apresentou o maior efeito indireto, via energia bruta (0,439).Palavras-chave: nutrição, valor nutritivo, estimativa, modelos lineares.

“…Determination of nutrient digestibility is the first step in evaluating the potentiality of an ingredient for use in the diet of reared species (Allan et al, 2000). Information on digestibility coefficients of feed ingredients is very useful not only to enable formulation of diets that maximize fish growth by providing appropriate amounts of available nutrients but also to reduce fish waste products (Lee, 2002).…”

Nine isonitrogenous (30% crude protein approximately) and isocaloric (18.23 kJ g -1 ) experimental diets (D1-D9) were formulated either with raw or treated (fermented with fish intestinal bacteria) Eichhornia crassipes leaf meal at 20%, 30% and 40% levels replacing other ingredients partially from a fish meal based reference diet (RD). Two specific strains of fish intestinal bacteria, Bacillus subtilis CY5 (isolated from Cyprinus carpio) and B. megaterium CI3 (isolated from Ctenopharyngodon idella) having extracellular cellulolytic and amylolytic activities, were used for fermentation of Eichhornia leaf meal for 15 days at 37°C. A commercial preparation of lactic acid bacteria (LAB), Lactobacillus acidophilus (Lactobacil) was used as feed supplement along with Bacillus subtilis CY5. Fermentation of leaf meal resulted in reduction of crude fibre, cellulose and hemicellulose contents and the antinutritional factors, tannin and phytic acid. However, free amino acids and fatty acids increased in the fermented leaf meal. The response of rohu fingerlings (4.0±0.14 g) fed the experimental diets for 80 days was compared with fish fed a RD. Both the inclusion level and type of Eichhornia leaf meal in diets significantly affected the growth performance of rohu. Fish fed diets containing 30% leaf meal fermented with CI3 strain performed better in terms of growth response, feed conversion ratio, protein efficiency ratio and apparent net protein utilization followed by diets containing 20% CI3 fermented leaf meal and 20% Bacillus subtilis + LAB fermented leaf meal in comparison with those with the RD. The apparent protein digestibility (APD) was better in fish fed diets containing fermented leaf meal. Highest deposition of protein in carcass was recorded in the group of fish fed 30% Bacillus subtilis + LAB fermented leaf meal diet whereas lipid deposition was highest in the fish fed the RD. It is concluded from the present study that Eichhornia leaf meal fermented with fish gut bacteria exhibiting extracellular enzyme activity can be recommended as a dietary ingredient in diets of Labeo rohita fingerlings up to 40% incorporation level replacing fish meal without any adverse effect on growth of the fish to produce cost effective formulated fish feed. Bacillus subtilis CY5 ile birlikte yem katkısı olarak kullanılmıştır. Su sümbülü yaprağının fermantasyonu, ham selülozun, selüloz ve hemiselüloz içeriğine ve anti-beslenme faktörlerine, tanen ve fitik asite indirgenmesi ile sonuçlanmıştır. Ancak, serbest asitler ve yağ asitleri fermente su sümbülü yaprağında yükselmiştir. 80 gün boyunca deneysel diet ile beslenen Rohu fingerling'in (4.0±0.14 g) tepkisi, RD ile beslenen balık ile kıyaslanmıştır. Dietlerdeki Eichhornia yaprağının hem içerik seviyesi hem de tipi rohu'nun büyüme performansını önemli şekilde etkilemiştir. %30 C13 türü ile fermente edilmiş su sümbülü yaprağı içeren balık yem diyetleri; büyüme tepkisi, yem dönüşüm oranı, protein verimlilik oranı ve belirgin net protein kullanımı açısından daha iyi performans gös...

“…A blend of different protein sources is often more effective than a single source (Hossain & Jauncey 1990;Webster et al 2000;Coyle et al 2004) as has been demonstrated for cuneate drum, Nibea miichthioides (Guo, Wang, & Bureau 2007); silver perch, Bidyanus bidyanus (Allan et al 2000); rainbow trout, Oncorhynchus mykiss ; channel catfish, Ictalurus punctatus (Mohsen & Lovell 1990); and yellowtail, Seriola quinqueradiata (Shimeno et al 1993).…”

A ten-week feeding trial was carried out to evaluate animal proteins, either alone or in combination (1:1:1), on the growth performances and economic benefit of climbing perch, Anabas testudineus. Four iso-proteinous (40%) diets were prepared, using fishmeal, protein concentrate, and meat and bone meal as major protein source in diets 1, 2 and 3, respectively, while diet 4 consisted of an equal proportion (1:1:1) of the above protein sources. Triplicate groups of fish (0.53 ± 0.02 g) were randomly stocked in 12 earthen ponds at a stocking density of 40,000 ha −1 . Fish fed diet 4 had significantly (P < 0.05) higher percent weight gain and SGR % per day −1 compared to the fish fed diets 1, 2, or 3. Significantly higher apparent protein efficiency ratio (1.25) and lower apparent feed conversion ratio (2.00) were also observed in fish fed diet 4. Total yield (1,123 kg ha −1 ) and net profit (Tk. 116,569 ha −1 ) were also higher in fish fed diet 4. It can be concluded that the combination of fishmeal, protein concentrate, The authors are grateful to the Laboratory of Aquatic Animal Nutrition, Faculty of Fisheries, Kagoshima University, Japan, for logistic support toward the chemical analysis.
