“…To determine the gross energy ( GE ), samples were subjected to combustion in a calorimetric pump (IKA C200 IKA Werke GmbH & Co.Kg, Staufen, BW, DE). To determine the indigestibility factor, an analysis of acid insoluble ash ( AIA ) was performed, according to the methodology described by Van Keulen and Young (1977) and adapted by Carvalho et al (2013) . Using the results obtained from diets and digesta, total digestible nutrients were determined: acid insoluble ash ( digAIA ), digestible crude protein ( digCP ), digestible crude energy ( digCE ), digestible ash ( digAsh ), and digestible dry matter ( digDM ).…”

“…Some fecal collection methods have been used to determine the digestibility of the nutrients and energy of feeds for monogastric animals. Among these methods are the total collection and the use of fecal indicator (acid insoluble ash, AIA); however, the respective obtained data are still contradictory (CARVALHO et al, 2013). Determining the digestibility by the traditional method of total excreta collection requires strict control of the intake and excretion, which causes this work to be costly (CARVALHO et al, 2013).…”

Thus, the objective of this study was to determine the apparent and standardized digestibility coefficients of phosphorus according to the phosphate particle sizes by applying two simultaneous methodologies.…”

545 MP45 = 88,8, e MP75 = 92,6. Os coeficientes de digestibilidade total estandardizada dos fosfatos avaliados pelo método do indicador, em valores percentuais foram: PPA = 75,9, PPB = 75,4, PPC = 75,6, MP15 = 84,9, MP45 = 78,0, e MP75 = 79,4. Considerando as duas metodologias avaliadas no presente trabalho, os fosfatos microgranulares constituem a melhor alternativa para a alimentação de suínos em fase de crescimento.Palavras-chave: marcador fecal, solubilidade in vitro, minerais, granulometria Rev.

“…Thereafter, excreta and feed samples were ground and sent to the laboratory for determination of dry matter, crude energy, and nitrogen contents according to D. J. Silva and Queiroz (2002), and insoluble acid ash using a methodology adapted from Carvalho et al (2013). The results obtained were used to calculate the apparent metabolizable energy (AME) values, according to the formulas described by Sakomura and Rostagno (2016).…”

“…Researchers are yet to find a substance with a perfect indicator feature. However, Carvalho et al (2013) showed that partial collection with marker method is comparable to the standard procedure of total collection of excreta, indicating that acid insoluble ash (AIA) can be used as a marker to predict the AME and digestibility coefficients of ingredients, as they present similar results.…”

The objective was to evaluate three sources of acid insoluble ash (AIA) (celite, kaolin, and sand), as indicators, to determine the apparent metabolizable energy of corn on a natural matter (AME) basis, dry matter digestibility coefficient (DMDC), and crude protein digestibility coefficient (CPDC) using total and partial excreta collection methods. Two hundred and ten Ross broiler chicks of 18 to 27 days of age were used. Broilers were adapted to experimental the diet for four days, and excreta were collected for 5 days. A reference diet (RD) based on corn and soybean meal was prepared to meet the nutritional requirements of the birds. A test diet was prepared with 40% replacement of RD with corn. The formulated diets were: D1, 99% Reference diet + 1% celite; D2, 59.4% RD + 39.6 % corn + 1% celite; D3, 99% Reference diet + 1% kaolin; D4, 59.4% RD + 39.6 % corn + 1% kaolin; D5, 99% Reference diet + 1% sand; D6, 59.4% RD + 39.6 % corn + 1% sand. The treatments were distributed in a completely randomized design, with six diets and five replicates of seven birds each in a 2x3 factorial arrangement. There were significant interactions for all variables investigated. It was observed that the AME and DMDC values of corn were similar in the two methods of collection, and PDC values using kaolin and celite makers were similar. However, the AME and CPDC of corn using sand with partial collection method were underestimated by 17.70 and 15.53%, respectively compared to those with the total collection method. The AME values of corn with the collection methods using celite and, the DMDC using celite and sand were significantly different. It was observed that the DMDC using celite and sand provided significantly lower values (4.67 and 5.15%), respectively, and the AME using celite was 2.86% lower than that obtained by total collection. To determine the EMA, DMDC, and CPDC in broilers, it is more efficient to use celiteTM and kaolin as markers with partial collection of excreta. Sand should not be used with partial excreta collection method, because it provides lower values of AME and CPDC compared to with total excreta collection method.
