Mineral deposition in tissues of cattle fed with different phosphates and relationships phosphorus: fluorine

Abstract

Forty-nine male calves were allotted in a randomized design, initially seven replicates per treatment at the end of the experiment were slaughtered four animals per treatment. Treatments CONT: control diet; FBC120: Dicalcium Phosphate 120:1 ratio P: F; MBC60: Monodicalcium phosphate 60:1 ratio P:F; FBC30: Dicalcium Phosphate 30:1 ratio P:F; SFT30: Super triple phosphate 30:1 ratio P:F; FBC10: Dicalcium Phosphate 10:1 ratio P:F; CAR10: concentrated ratio of 10:1 rock Q:F. Phosphates less elaborate showed higher amounts of heavy metals. In bones, iron, aluminum and lead were higher in FBC10 diet, the copper content was higher in animals fed the diet MBC60. Magnesium in liver was higher in animals fed diet FBC30, aluminum was higher for treatments SFT30 and FBC10, FBC120 and the cadmium and lead levels were higher in animals that received STF30. Treatments did not affect phosphorus and fluorine in muscle and heart, being that chromium was higher in the muscle of animals fed diets CAR10 and STF30 while cadmium in heart was greater in diet CAR10. Kidney phosphorus was higher in the animals fed the diet CAR10 and lower dietary FBC10, while aluminum was higher in the animals fed with the diet FBC10 and lower dietary FBC120 and levels of chromium and lead were higher in animals CAR10 diet and lowest in diet MBC60. Alternative sources of phosphorus and low ratios P:F increased the deposition of minerals in bones and liver, and this mineral deposition was lower in the muscles.

Blood and bone parameters of cattle fed diets containing different phosphates and phosphorus: fluorine relations

“…The fixation sites of several chemical elements in the different biological tissues constitutes a relevant evaluation in order to determine the direct effect of the nutritional strategies upon the healthy and production of the animals as well as the nutritional content of each biological tissue, when employed in the human nutrition (TEIXEIRA, et al, 2013b). Indeed, nutritional strategies aiming a more effective absorption have been evaluated regarding the process of ruminant digestion, aiming to obtain a higher understanding of the chemical interactions between nutrients in the digestive system as well as an Rev.…”

“…Usually, the tropical forages are deficient in several mineral salts. Phosphorus deficiency is maybe the most common and it is associated to the most effective economic losses in bovine production (TOKARNIA et al, 2010). Frequently, the phosphorus deficiency is corrected employing conventional sources of this chemical element, which is the case of the dicalcium phosphate (DC).…”
