“…It can also be related to the species used and excess of other parts such as shrimp shell in the feedstock. In contrast, CDACP (97.67%) corroborates the results of Terrazas-Fierro et al (2010) (98.0%), and higher than those found by Akiyama et al (1989) (74.6%) and Mu et al (2000) (88.2%), which may have been influenced by the ability of crustaceans to better use the protein of the soluble carbohydrates (ROSAS et al, 2002).…”

-Studies on feeding and nutrition of shrimp are still quite scarce; little is known about the use of agribusiness byproducts in shrimp diets. Therefore, this study aimed to perform nutritional and energy assessments of protein-based ingredients for feed of shrimp of the Litopenaeus vannamei species. The design was completely randomized, with six treatments and four replications: a standard diet and five test diets composed of 70% standard diet and 30% test ingredients (poultry viscera flour -PVF, cassava leaf hay -CLH, shrimp head flour -SHF, sugarcane yeast -SCY and castor bean meal -CBM). We used a total of 720 shrimps with mean weight of 8 g each. AVALIAÇÃO NUTRICIONAL DE INGREDIENTES PARA O CAMARÃO BRANCO DO PACÍFICORESUMO -Os estudos sobre alimentação e nutrição de camarões ainda são muito escassos, pouco se sabe sobre o aproveitamento pelos camarões de subprodutos da agroindústria, portanto o objetivo deste trabalho foi à avaliação nutricional e energética de ingredientes proteicos para camarões (Litopenaeus vannamei). O delineamento foi inteiramente casualizado, com seis tratamentos e quatro repetições: uma Reference diete cinco dietas teste compostas de 70% da Reference diete 30% do ingrediente teste (farinha vísceras de aves-FVA, feno folha de mandioca-FFM, farinha cabeça de camarão-FCC, levedura de cana-de-açúcar-LC e farelo de mamona -FM). Utilizou-se 720 camarões com peso médio de 8g. Os parâmetros de qualidade não apresentaram diferença significativa pelo teste de Tukey (P > 0,05). Os coeficientes de digestibilidade aparente dos ingredientes FVA, FFM, FCC, LC e FM foram respectivamente, 27,44; 76,26; 77,78 e 90,10% para matéria seca;76,61; 70,44; 97,67 e 78,29% para proteína e (33,10; 51,19; 90,70 e 78,05%) para energia bruta. A energia digestível dos ingredientes foi 1.749, 2.457, 3.914, 3.030 e 2.130 kcal/kg e proteína digestível foi de 42,4; 16,09; 54,62, 23,71 e 14,31%. A FCC apresentou os maiores coeficientes de digestibilidade aparente da proteina bruta e energia bruta e para energia digestível. A LC apresentou o maior valor do coeficiente de digestibilidade aparente da matéria seca. A FCC e a LC são os ingredientes que apresentaram os melhores aproveitamentos dos nutrientes e da energia para L. vannamei. Palavras-chave: Alimentos alternativos. Energia Digestível.

“…When the hepatopancreas is saturated, glycogen can act as a physical barrier preventing the amino acids and peptides into the B cells of the hepatopancreas, indirectly affecting growth. In that case, a high dietary carbohydrate content can indirectly affect growth because the amino acids and peptides can be lost through fecal excretion (Rosas et al, 2002). In the present study, it was observed that the growth rate of crayfish juveniles was reduced just in animals fed with cornstarch exceeded 200 g kg −1 which produced a hepatopancreas glycogen concentration above the inflection point in the curve between hepatopancreas glycogen concentration and cornstarch levels.…”

“…Shrimps, in particular, appear to exhibit less preferential utilization of carbohydrates as an energy source (Alava and Pascual, 1987;Bages and Sloane, 1981;Rosas et al, 2002;Shiau and Peng, 1992). Stone et al (2003) suggested that the ability of animals to utilize dietary carbohydrate as an energy source depends on digestibility, endogenous metabolic enzymes, and assimilation of different dietary carbohydrates.…”

“…The proteins are essential nutrients for the penaeoids shrimps because they are basic for growth, the regulation of the internal osmotic pressure, the gluconeogenesis and the immune system (Rosas et al, 2002). Therefore variations of this nutrient in haemolymph can be used as good indicator of general physiological state.…”

ABSTRACT. The present study compared the effect of different starch/cellulose ratios (30/0, 20/10, 10/20, 0/30) on the metabolic response and apparent digestibility in two species of penaeoids: Artemesia longinaris and Pleoticus muelleri. Adult animals were used in order to obtain sufficient quantities of haemolymph and faecal material for analysis. No significant differences were found in levels of plasma metabolites in P. muelleri, but in A. longinaris, a significant increase was observed in glucose, total protein, and cholesterol in correlation with increased dietary starch. The apparent digestibility coefficients decreased from 83.7% to 51.2% (A. longinaris) and from 71.9% to 7.6% (P. muelleri) as the dietary starch levels increased. The ratio of amylase activity to protease activity (A/P ratio) declined in A. longinaris when the percentage of dietary starch increased. In contrast, the A/P ratio for P. muelleri increased with higher starch concentrations. These results demonstrated a close relationship between the feeding habits and digestive physiology of the two species studied; they also suggest a more herbivorous behavior for A. longinaris and more omnivorous habits for P. muelleri. Keywords: Artemesia longinaris, Pleoticus muelleri, apparent digestibility, carbohydrate metabolism, cellulose, starch, haemolymph, Argentina.Influencia del nivel de almidón y celulosa en la dieta sobre el perfil metabólico y digestibilidad aparente en camarones penaeoideos RESUMEN. En el presente estudio se comparó el efecto de diferentes concentraciones de almidón/celulosa (30/0; 20/10; 10/20; 0/30) sobre la respuesta metabólica y la digestibilidad aparente en dos especies de peneidos, Artemesia longinaris y Pleoticus muelleri. Se utilizaron animales adultos a fin de obtener cantidades suficientes de hemolinfa y heces para los análisis. No hubo diferencias significativas en los niveles de metabolitos plasmáticos en P. muelleri, en cambio en A. longinaris se observó un incremento significativo de la glucosa, proteínas totales y colesterol en relación con el aumento del almidón en la dieta. Los coeficientes de digestibilidad aparente disminuyeron de 83,7% a 51,2% (A. longinaris) y de 71,9% a 7,6% (P. muelleri) a medida que los porcentajes de almidón en la dieta aumentaron. El cociente entre la actividad de amilasa y proteasa (A/P) se redujo en A. longinaris con los mayores porcentajes de almidón dietario; por el contrario, el cociente A/P en P. muelleri aumentó cuando la concentración fue más alta. Estos resultados demostraron que existe una estrecha relación entre los hábitos alimentarios y la fisiología digestiva de las dos especies estudiadas; sugiriendo un comportamiento más herbívoro para A. longinaris y más omnívoro para P. muelleri.
