“…The double xylanase dose and NSP-ase cocktail improved feed conversion in birds fed the barley-based diet in the grower phase (d 12–23). This is in agreement with Hashemi et al. (2017) who found that supplementing an NSP-ase cocktail containing ß-glucanase, cellulase, α-amylase, xylanase, and protease, or just combined xylanase and ß-glucanase, to a barley-based diet resulted in reduced FCR in the grower period (d 15–28).…”

“…Carbohydrate-Active enZymes (CAZymes) have been applied in monogastric livestock as feed additives [ 12 , 13 ]. Beyond its recognized ability to degrade cereal cell walls [ 14 ], CAZymes also demonstrated the capacity to disrupt microalgae cell walls [ 15 , 16 ]. Recently, a recombinant four-CAZyme mixture, was developed in vitro to partially degrade the C. vulgaris , enabling the release of trapped nutrients [ 17 ].…”

Impact of dietary Chlorella vulgaris and carbohydrate-active enzymes incorporation on plasma metabolites and liver lipid composition of broilers

Background Chlorella vulgaris has been proposed as a sustainable green feedstock in poultry nutrition due to its ease of cultivation, minimal environmental impact and balanced nutritional composition. However, the majority of studies documents the use of C. vulgaris as a dietary supplement in broilers instead of a feed ingredient. To the best of our knowledge, no report has shown the effect of a high-level incorporation (>2 % in the diet) of C. vulgaris on plasma metabolites and hepatic lipid composition of broilers. One hundred and twenty Ross 308 male birds were housed in 40 wired-floor cages and randomly distributed by the following experimental diets at 22 days of age (n = 10) during 15 days: (1) a corn-soybean meal based diet (control); (2) based diet with 10% of C. vulgaris; (3) diet 2 supplemented with 0.005% Rovabio® Excel AP; and (4) diet 2 supplemented with 0.01% of a pre-selected four-CAZyme mixture. Results The inclusion of C. vulgaris at 10% in the diet, regardless of the presence of exogenous CAZymes, changed plasma metabolites but did not compromise broilers growth. Plasma total lipids increased in broilers fed C. vulgaris combined with the two feed CAZymes (p < 0.001) compared with the control diet. Moreover, the supplementation with Rovabio® increased total cholesterol and LDL-cholesterol, while the addition of the four-CAZyme mixture increased triacylglycerols, VLDL-cholesterol and ALP activity. In opposition, HDL-cholesterol levels decreased in broilers fed microalga alone (p = 0.002). Regarding hepatic composition, the inclusion of C. vulgaris in broiler diets, individually or combined with exogenous CAZymes, had a minor effect on fatty acids but improved the n-6/n-3 ratio and total carotenoids. Conclusions In summary, the inclusion of a high level (10%) of C. vulgaris in broiler´s diet, regardless of the presence of exogenous CAZymes, improved hepatic antioxidant composition and did not impair broiler’s performance. In addition, the feed supplementation with CAZymes increased broilers lipemia. Therefore, dietary C. vulgaris at this incorporation level seems to be safe for animal health and do not compromise performance traits, with no need of CAZymes supplementation.

La industria camaronera es el creador de toneladas de residuos sólidos tales como las cabezas y exoesqueletos, ya que la única parte que se consume el abdomen de este crustáceo. Al mismo tiempo el crecimiento exponencial de la población exige una producción más rápida de alimentos y productos finales, el desarrollo de alimentos a partir de fuentes no tradicionales podría convertirse en una fuente sostenible y sustentable. El objetivo es la creación de un balanceado de pollos alta en proteínas a partir de los residuos, siendo la carne de pollo el segundo alimento más consumido en el país después de otros productos como la leche, el pan y el arroz. Es por ello la importancia de dar un uso a este subproducto de las industrias camaroneras para disminuir la contaminación que produce, mediante la obtención de un producto con mayor valor agregado, en la revisión bibliográfica no se ha encontrado evidencia de la formulación de un balanceado que incluya este residuo, además que tenga alto valor proteico y sea más económico que los alimentos convencionales.
