A research program was carried out to improve and facilitate rotifer (Brachionus plicatilis) culturing as well as to assure their optimal nutritional quality as a prey, concentrating on the development of a dry and complete rotifer diet that does not require the use of algae and does result in a HUFA rich Brachionus. The present poster provides results dealing with culture aspects and rotifer nutritional quality. Different diet compositions based on single cell proteins enriched with various nutritional additives were evaluated. Results obtained so far demonstrate that a selected formula of a combined culture and enrichment diet, that does not involve the use of microalgae at all, can be successfully used for growing...

Studies evaluating the protein nutritive value of beans labelled with 15N, ussing nitrogen balance and the quantitation of faecal and urinary endogenous nitrogen, determined by isotopic dilution, have been extensively used. The objective of this research was to verify if the isotopic labelling of raw, freeze dried beans (Phaseolus vulgaris L., cultivar Piratã 1) with 1.394 atoms%15N, resulted in the same abundance of the whole flour and of the protein fractions extracted from the beans with 0.5 mol L-1 NaCl. The isotopic abundance found in the whole bean flour, in the protein extract, in the globulin and albumin fractions were respectively: 1.394 ± 0.011; 1.403 ± 0.012; 1.399 ± 0.007 and 1.399 ± 0.028 atoms % of 15N, presenting no difference (P > 0.05)....

Nutrient analyses were done in melted ice, frazil and sea water of the upper part of the water column, where as major constitutive elements of micro-algae were analysed. Measurements of nutrient uptake were carried out with frazil algae incubated at -1.5 degree C in a field incubator. Differential-enrichment bioassays and mean N/P ratio (5.9) demonstrated that actual growth of the cultures was nutrient-limited. Nitrogen governed the algal yield when illumination and grazing allowed the microalgae to grow. It concluded that the epontic dynamics is not only controlled from above, by the seasonal (climatic) changes in light intensity as generally assumed, but also from below, by the short-term (hydrodynamic) events of vertical mixing that replenish the...

Fifty-seven by-products were collected from regions throughout Brazil. Chemical composition, in vitro neutral detergent fiber digestibility (IVNDFD), and total digestible nutrients (TDN) were determined with the objective of grouping by-products with similar nutritional characteristics. The by-products belonging to group one (G1) presented the highest content of neutral detergent fiber exclusive of ash and nitrogenous compounds [aNDFom(n)] and lowest energy content, with 42.5% and 38.8% of IVNDFD and TDN, respectively. A new cluster analysis was carried in order to better characterize G2 by-products, six subgroups (SGs) were established (SG1 to SG6). SG1 by-products had the highest and the lowest values for lignin and TDN, respectively. SG2 by-products had...

The objective of the present study was to evaluate the nutritional value of elephant-grass silages containing annato byproduct. Twenty intact rams were distributed in a complete randomized block design with five diets (0; 4; 8; 12 and 16% annato byproduct in the silage) and four replications and used to estimate the intake, apparent nutrient digestibility, content of total digestible nutrients and nitrogen balance. The addition of annato byproduct raised the intakes of dry matter (DM), organic matter (OM), crude protein (CP), neutral detergent fiber (NDF), acid detergent fiber (ADF), ether extract (EE), total carbohydrates (TC), non-fibrous carbohydrates (NFC) and total digestible nutrients (TDN), in body weight (%BW) and in metabolic weight (g...

A cultivar Xaraés (Brachiaria brizantha), coletada em Burundi. África, foi liberada pela Embrapa em 2003 após 15 anos de avaliações. É uma planta cespitosa, de 1,5 m de altura, folha lanceolada e longa, com poucos pêlos e de coloração verde-escura. Os colmos são finos e radicantes nos nós, e as inflorescência são grandes, como espiguetas em uma só fileira. A cultivar Xaraés é apomítica e penteploíde, com 45 cromossomos. Irregularidades na divisão meiótica reduzem a validade do pólen para, aproximadamente, 79%. Seus principais atributos possitivos são a alta produtividade, especialmente de folhas, a rápida rebrota e o florescimento tardio, prolongado o período de pastejo até o período seco. Além disso, apresenta bom valor nutritivo e alta capacidade de...

Palatability enhancing nutrients for the European eel, Anguilla anguilla L.

Pacolet, W.; Reynders, K.; Ollevier, F.P..

Feeding experiments with European glass eels Anguilla anguilla L. demonstrated a high degree of attractiveness for the natural diets Tubifix and cod roe. Previous experiments had indicated that incorporation of bovine spleen and/or blood into paste feeds significantly improved the growth rate and survival. To increase feed consumption, the effect of some basic components available from the current generation of chemo-attractants were evaluated. Using a modified Omission Test Procedure, we focused on monosodiumglutamate, betaine, the nucleotides IMP and GMP, and fractions of cattle blood. These components were incorporated into non-attractive casein-based test diets and administered following standardized procedures to intensively...

Prediction of the Nutritive Value of Pasture Silage by Near Infrared Spectroscopy (NIRS)

Chilean J. Agric. Res.

Restaino,Ernesto A; Fernández,Enrique G; La Manna,Alejandro; Cozzolino,Daniel.

The aim of this study was to investigate the use of near infrared reflectance (NIRS) spectroscopy to predict the nutritive value of silages from pastures and to assess the effect of silage structure type (e.g. bunker and bag silos) on the NIRS predictions. Samples (n = 120) were sourced from commercial farms and analyzed in a NIRS monochromator instrument (NIR Systems, Silver Spring, Maryland, USA) using wavelengths between 400 and 2500 nm in reflectance. Calibration models were developed between chemical and NIRS spectral data using partial least squares (PLS) regression. The coefficients of determination in calibration (R²) and the standard error in cross validation (SECV) were 0.73 (SECV: 1.2%), 0.81 (SECV: 2.0%), 0.75 (SECV: 6.6%), 0.80 (SECV: 6.7%),...

Preliminary results on the nutritional evaluation of omega-3-HUFA-enriched Artemia nauplii for larvae of the sea bass, Dicentrarchus labrax

Van Ballaer, E.; Amat, F.; Hontoria, F.; Léger, P.; Sorgeloos, P..

Freshly hatched San Pablo Bay and Great Salt Lake Artemia nauplii (omega-3-HUFA-poor) and enriched meta-nauplii (omega-3-HUFA-enriched)were compared to reference Artemia nauplii (omega-3-HUFA-rich) as a food source for the larvae of the sea bass, Dicentrarchus labrax. Significant differences in survival and biomass production between the treatments could be attributed to the omega-3-HUFA content of the food. A delayed mortality in fish larvae fed the Great Salt Lake Artemia is suspected to be caused by a high level of alpha-BHC in this Artemia source. Growth was not significantly different between the treatments, most probably due to the large variation in growth...

O experimento foi conduzido em Cáceres, Estado do Mato Grosso, com o objetivo de avaliar o efeito de doses de nitrogênio sobre a produção de forragem e a composição química do capim-tifton 85 (Cynodon spp.). Utilizou-se o delineamento em blocos completos casualizados com cinco tratamentos (0, 60, 120, 180 e 240 kg há-1 de N) e quatro repetições, em parcelas de 4,0 x 5,0 m. Foram realizados quatro cortes a intervalos de 30 dias, na altura de 5 cm do nível do solo, sendo as doses de N parceladas em quatro aplicações após cada corte, sob a forma de ureia, em cobertura. Foi observado, para cada kg ha-1 de N aplicado, aumento, na produção de matéria seca total de 22,67 kg ha-1, na produção de lâmina foliar verde de 11,37 kg ha-1, na altura do relvado de 0,052...

This paper describes a pilot culture system for the production of on-grown Artemia in freshwater ornamental fish farms. The system had 21 culture units, each consisting essentially of three components: an oval-shaped raceway, an air-water lift system and two waste collectors. Using artificial seawater at 20 ppt for culture and at a mean production rate of 3 kg/m3 of water in a 12-day cycle, the system had a production capacity of 8 metric tons of on- grown Artemia a year. Biochemical analyses were preformed to evaluate the nutritional value of the on-grown Artemia against three conventional live feeds, viz. live Artemia nauplii, live Moina...
