“…Similarly as in the case of Mg, absorption of Cu in the small intestine was not large (Table 3). Loading with Ca did not significantly affect its distribution in the digestive tract or absorption, which has been reported in the works of Alfaro et al (1988) and Tucker et al (1988). McDowell (1992) reports that absorption of Cu in adult ruminants ranges from 1 to 3%, emphasizes its variability and the occurrence of numerous interactions with other dietary components such as phytins, Ca, Zn, Fe.…”

“…As the concentration of these elements in the diet rises, their specific antagonisms in terms of absorption and tissue distribution of other minerals becomes increasingly evident (Chicco et al, 1973;Bartley, 1976;NRC, 1980;Shiga and Harii, 1987;Alfaro et al, 1988). Antagonism between elements can lead to a deficit of many elements, especially those that normally occur in feeds at near-minimum levels (Underwood, 1977;Alfaro et al, 1988;Tucker et al, 1988).…”

Experiments were carried out on sheep to assess the effect of rations containing excess calcium and sodium (5 and 10 times more than recommended in the ARC requirements) on the apparent digestibility and absorption of macro-(K, Na, Mg, Ca, P) and microelements (Zn, Cu) in the forestomachs and small intestine of sheep. The introduction of calcium lactate (20% DM) into an extruded concentrates led to a significant decline in Mg digestibility and elevated Ca digestibility in the forestomachs and a decline in P digestibility in the segments of digestive tract between the mouth to the ileum (forestomachs + small intestine). Excess Na in the diet (12 g/d) significantly reduced K absorption in the small intestine. Loading sheep with Ca and Na did not affect the absorption of microelements in the small intestine or in the segment between the mouth and ileum.

“…A quantidade de Ca absorvida pelo animal está relacionada com ingestão de Ca, "status" de Ca do animal, idade do animal, quantidade requerida de Ca, fonte e fórmula química que o Ca ocorre na dieta, "status" de vitamina D do animal e inter-relação com outros elementos inorgânicos (McDOWELL et al 1983;REID et al, 1987;ALFARO et al, 1988;e NRC, 1989e NRC, e 1996.…”

Consumo e absorção aparente total de macroelementos inorgânicos (Ca, P, Mg, K e Na), em bezerros da raça holandesa alimentados com dietas contendo diferentes níveis de volumoso

RESUMO -Este estudo visou avaliar os efeitos dos diferentes níveis de volumoso nas dietas sobre os consumos e as absorções aparentes de cálcio (Ca), fósforo (P), magnésio (Mg), potássio (K) e sódio (Na). Trinta e cinco bezerros da raça Holandesa puros por cruzamento, não-castrados, com idade média de 60 dias e peso vivo inicial de 78 kg, foram distribuídos em delineamento inteiramente casualizado, com nove repetições por dieta, exceto para a dieta com 10% de volumoso, com oito repetições. Os animais foram alimentados à vontade com dietas contendo níveis de 10, 25, 40 e 55% de volumoso, na base da MS, usando-se feno de capim coast-cross (Cynodon dactylon), fubá de milho e farelo de soja, os quais constituíram dietas com aproximadamente 16% de PB. Os coeficientes de absorção aparente foram obtidos por intermédio de ensaios de digestibilidade, realizados aos 120 e 180 dias de idade dos animais, sendo usado como indicador o óxido crômico para estimar a excreção fecal. O consumo máximo diário de 10,96 g de P foi estimado com 42,40% de volumoso na dieta. Os consumos de Mg e K aumentaram, o de Na decresceu linearmente e o de Ca não foi influenciado com o aumento de volumoso na dieta. Os coeficientes de absorção aparente de Ca, P, Mg e Na não foram influenciados, enquanto o de K decresceu linearmente com aumento dos níveis de volumoso nas dietas. Os consumos de P, Mg, K e Na e a absorção aparente de K foram influenciados pelos níveis de volumoso nas dietas.Palavras-chave: absorção aparente, bezerro holandês, consumo, mineral, nível de volumoso Intake and Apparent and Total Absorption of Inorganic Macroelements (Ca, P, Mg, K and Na) in Holstein Calves Fed Diets with Different Levels of ForageABSTRACT -This study was to evaluate the effects of different levels of forage in the diet on the intake and apparent absorption of calcium (Ca), phosphorus (P), magnesium (Mg), potassium (K) and sodium (Na). Thirty five pure Holstein bull calves, 60 days old with initial average live weight (LW) of 78 kg, were allotted in a completely randomized experimental design with nine replicates per diet, except for the 10% forage diet, with eight replications. The animals were ad libitum fed with diets contained 10, 25, 40 and 55% of forage, on the DM basis, using chopped coast-cross (Cynodon dactylon) grass, ground corn and soybean meal, which constitutes diets with approximately 16% CP. The apparent absorption coefficients were obtained by means of digestibility trials, carried out at 120 and 180 days of the animals age, being used the chromium oxide as a marker to estimate the fecal excretion. The maximum daily intake of 10.96 g of P was estimated with 42.40% of forage in the diet. The intakes of Mg and K increased, while the Na decreased linearly and the Ca was not affected by the forage level in the diet. The apparent absorption of Ca, P, Mg and Na were not affected, while the K decreased linearly with the forage levels in the diets. The intakes of P, Mg, K and Na and apparent absorption of the K were affected by the forage levels in th...
