“…Soluble non-starch oligosaccharides negatively interfere with the absorption of minerals (Arruda, 2003). Although SPC has a higher concentration of minerals due to processing (Miranda, 2012), the metabolization of nutrients decrease in the content of α-galactosides, the excretion of minerals (Fischer et al, 2002) causing CMA increase -contradicting the results.…”

Two experiments were carried out to evaluate the effect of using soy protein concentrate (SPC) in pre-starter and starter diets for broilers. In the first experiment, 600 male Cobb broilers, between one and 40 days of age, were distributed in a completely randomized design, with four treatments and six replications of 25 birds each. Treatments were ofered to broilers in the pre-starter and starter diets and consisted of inclusion of soy protein concentrate (0,3,6 and 9%) in diets. The parameters evaluated were: body weight gain, feed conversion ratio, consumption of ration, enzyme production in the pancreas, villus: crypt ratio, leukocyte count and immunoglobulin A (IgA) dosage. Aimed to determine the coefficient of nutrient metabolization of feeds, 144 male Cobb chicks were distributed, between 14 and 21 days of age, with four treatments and six replications of six birds per experimental unit. Treatments were the same as in the first experiment. The use of 3 and 9% of SPC did not affect weight gain, feed intake, feed conversion or viability of the poultry. The use of 6% of SPC provided an increase in trypsin activity, villi length and crypt depth; the coefficient of dry matter metabolization increased linearly; but no differences were observed in performance or immunological parameters.

“…According to Conte et al (2003), the increased viscosity of chymos, promoted by the NSP, can lead to decreased digestion of proteins, fats, carbohydrates, and also micronutrients, since they are less available to the enzymatic action in the small intestine. Moreover, they have a strong ionic bonding ability with mineral elements, causing the fiber-rich diets to interfere negatively in the absorption of minerals (Arruda et al, 2003). Another possibility would be a possible interaction between caffeine and calcium absorption.…”

Fiber source and xylanase on performance, egg quality, and gastrointestinal tract of laying hens

et al. 2019

The objective of this study was to ascertain the influence of different dietary fiber sources and the usage of xylanase on diet of commercial layers and their influence on productive performance, egg quality, and digestive organ biometry. A total of 864 Lohmann ® White hens was fed diets with three different fiber sources (wheat bran, soybean hull, or coffee husk) with or without xylanase inclusion (concentration of 160,000 BXU/g) in a 3×2 factorial arrangement, with six replicates of 24 birds each, from 25 to 44 weeks of age. There were no interactions between dietary fiber and xylanase inclusion. The enzyme supplementation did not influence any parameters evaluated. There were dietary fiber effects on body weight gain, viability, egg weight, eggshell quality, yolk pigmentation, and liver and gizzard relative weights. Wheat bran, soybean hull, and coffee husk can be used in laying hen diets without detrimental effect on productive performance. The enzyme used had no effect on the performance and eggshell quality of laying hens.

Influência da adubação potássica na qualidade e no potencial antioxidante do sapoti em diferentes estádios de desenvolvimento

et al. 2017

A composição química e o estádio de maturação podem interferir no ponto de colheita do sapoti, a depender da destinação do fruto. Consequentemente, objetivou-se, com este trabalho, avaliar a influência da adubação potássica na qualidade e no potencial antioxidante do sapoti, em diferentes estádios de desenvolvimento. O experimento foi instalado na fazenda Norfruit, em Pau Branco, Mossoró, RN. O delineamento adotado foi em blocos casualizados, em esquema fatorial 5 x 6, composto por cinco doses de potássio (0, 200, 400, 600 e 800 g de K por planta) e seis estádios de desenvolvimento, com cinco repetições. Os frutos foram marcados ao atingirem 10 a 15 mm de comprimento; sendo colhidos e avaliados 90, 120, 150, 180 e 200 dias após sua marcação e completamente maduros (após oito dias de armazenamento a 25 ± 2 ºC e 58 ± 5% UR). O sapoti pode ser colhido 200 dias após a floração plena, quando atinge seu tamanho máximo e apresenta qualidade adequada para o consumo. O sapoti maduro tem maior teor de açúcares e menor concentração de compostos bioativos e atividade antioxidante. A dose de 400 g por planta de K proporciona frutos de maior massa, com maiores concentrações de polifenóis extraíveis totais e atividade antioxidante. A atividade antioxidante do sapoti está mais correlacionada com a concentração de polifenóis extraíveis totais. Palavras-chave: Influence of potassium fertilization on quality and antioxidant potential of sapodilla at different development stagesThe chemical composition and stage of maturation may interfere with harvest point of sapodilla depending on the destination of the fruit. This study aimed at evaluating the influence of potassium fertilization on quality and antioxidant potential of sapodilla at different development stages. The experiment was carried out on farm Norfruit, in Pau Branco, Mossoró, RN. The experimental design was completely randomized blocks in a 5 × 6 factorial scheme, consisting of five doses of potassium (0, 200, 400, 600, and 800 g K for plant) and six development stages, with five repetitions. The fruits were marked when reaching 10 to 15 mm in length, being collected and evaluated after 90, 120, 150, 180, and 200 days after being marked and when they were fully mature (after eight days of storage at 25 ± 2 °C and RH 58 ± 5%). Sapodilla can be harvested 200 days after full bloom, when it reaches its maximum size and presents adequate quality for consumption. The ripe sapodilla has higher concentration of sugar and lower concentration of bioactive compounds and antioxidant activity. The dose of 400 g of K per plant generated fruits of greater mass, with higher concentration of polyphenols and antioxidant activity. The antioxidant activity of sapodilla is more correlated with total extractable polyphenol concentration.
