          Abstract

          Resumo Este trabalho teve como objetivo avaliar o efeito da adição de um acidificante em dietas sobre a digestibilidade de nutrientes em suínos em crescimento. Foram utilizados 18 suínos, com peso médio inicial de 53,55 kg, e os tratamentos constituíam de dieta convencional (milho e farelo de soja) e alternativa (milho pré-cozido e soja integral desativada), acrescidas de um acidificante nos níveis 0%, 0,1% e 0,2%. Os animais ficaram alojados em três baias coletivas, sendo que em cada arraçoamento eram colocados em boxes individuais. O método de coleta de fezes foi realizado diretamente na ampola retal e 0,34% de Cr2O3 foi utilizado como indicador. O delineamento experimental utilizado foi de blocos ao acaso, em arranjo fatorial 2 x 3 (dietas x níveis de acidificante). A dieta alternativa foi pior para a digestibilidade da PB (P<0,03) e resíduo mineral (P<0,001), porém melhorou a digestibilidade de variáveis da fibra (FB, P<0,001; e FDA, P<0,001). A adição de 0,2% do acidificante às dietas melhorou a digestibilidade do Ca (P<0,01). Houve interação entre acidificante e dieta para os coeficientes de digestibilidade da MS (P<0,01) e FDN (P<0,02). A dieta alternativa apresentou coeficiente de digestibilidade da MS superior à convencional quando adicionados 0,1% do acidificante, sendo respectivamente, 86,02% e 84,51% (P<0,05). Nos resultados de digestibilidade da FDN, a dieta alternativa apresentou valor superior à convencional no nível 0% ou 0,1% do acidificante. Para a dieta alternativa com 0,2% foram obtidos valores maiores que nos níveis 0 ou 0,1% (P<0,05).

          Abstract The aim of the experiment was to evaluate the effect of the addition of acidifiers to diets on the digestibility of growing pigs. We used 18 pigs with an average initial weight of 53.55 kg. The treatments consisted of conventional diet (corn and soybean meal) and alternative diet (pre-cooked corn and inactive soybean), with the addition of an acidifier at the levels of 0%, 0.1%, and 0.2%. The experimental design was in randomized blocks in a 2 x 3 factorial arrangement (diets x levels of the acidifier). The alternative diet was worse for CP (P<0.03) and ash (P<0.001) digestibility, but improved fiber digestibility (CF, P <0.001; ADF, P <0.001). The addition of the acidifier (0.2%) improved digestibility of Ca (P <0.01). There was an interaction between the acidifier and diet on digestibility coefficients of DM (P <0.01) and NDF (P<0.02). The alternative diet showed higher DM digestibility than the conventional diet when added 0.1% acidifier, respectively, 86.02% and 84.51% (P<0.05). As for NDF digestibility results, the alternative diet showed higher values than the conventional diet with the addition of 0% or 0.1% of the acidifier. For the alternative diet with 0.2%, values greater than 0 or 0.1% (P<0.05) were obtained.

          Digestion of the polysaccharides of some cereal foods in the human small intestine.

          The digestion and absorption of dietary starch and nonstarch polysaccharides (NSP) in the small intestine of man from oats, cornflakes, and white bread has been determined by feeding seven ileostomists test meals containing these foods and estimating carbohydrate recovery in the effluent. NSP, the main constituent of dietary fiber, was almost completely recovered from all three test meals, including the water soluble beta-glucan which is the main NSP in oats. Less than 0.6% of the starch in oats was recovered as starch with a further 1.2% as dextrins and maltose. 4% of cornflake starch however was recovered, of which the main part was resistant to alpha-amylase digestion in vitro unless specially dispersed. Similarly with white bread 2.5% of ingested starch reached the terminal ileum of which the greater part was starch resistant to alpha-amylase in vitro. Overall 5.8% of the carbohydrate in white bread, 5.3% in cornflakes, and 11.7% in oats was recovered. This study supports the view that human digestive enzymes do not break down dietary NSP. It also identifies a fraction of starch, RS, present in processed food which resists breakdown by alpha-amylase both in vitro and in the small intestine of man.

            The effects of calcium benzoate in diets with or without organic acids on dietary buffering capacity, apparent digestibility, retention of nutrients, and manure characteristics in swine.

            Eight barrows (Yorkshire x [Finnish Landrace x Dutch Landrace]), initially 30 kg BW, were fitted with ileal cannulas to evaluate the effects of supplementing Ca benzoate (2.4%) and organic acids (OA) in the amount of 300 mEq acid/kg feed on dietary buffering capacity (BC), apparent digestibility and retention of nutrients, and manure characteristics. Swine were allotted in a 2 x 4 factorial arrangement of treatments according to a cyclic (8 x 5) changeover design. Two tapioca-corn-soybean meal-based diets were formulated without and with acidogenic Ca benzoate. Each diet was fed in combination with OA (none, formic, fumaric, or n-butyric acid). Daily rations were equal to 2.8 x maintenance requirement (418 kJ ME/BW(.75)) and were given in two portions. Chromic oxide (.25 g/kg) was used as a marker. On average, Ca benzoate lowered BC by 54 mEq/kg feed. This salt enhanced (P < .05) the ileal digestibility (ID) of DM, OM, arginine, isoleucine, leucine, phenylalanine, alanine, aspartic acid, and tyrosine (by up to 2.4 percentage units). Also, the total tract digestibility (TD) of DM, ash, Ca and GE, and Ca retention (percentage of intake) was greater (P < .05) in swine fed Ca benzoate, whereas N retention remained unaffected. Addition of all OA (formic and n-butyric acid, in particular) exerted a positive effect (P < .05) on the ID of amino acids (except for arginine, methionine, and cysteine). A similar effect (P < .05) was found for the TD of DM, OM, CP, Ca and total P and for the retention of N and Ca. In swine fed Ca benzoate, urinary pH decreased by 1.6 units (P < .001). In conclusion, dietary OA have a beneficial effect on the apparent ileal/total tract nutrient digestibilities, and Ca benzoate increased urine acidity, which could be effective against a rapid ammonia emission from manure of swine.
