Budiyono E-mail: ijse live. The experimental unit was represented by the animal. The animals were disposed in pens, which contained feeders and water drikers.
These animals received complete mineral mixture, excepting phosphorus, which was furnished, ad libitum, in a specific feeder. The phosphorus P sources employed in the present work were commercial products that are available in the market and authorized by the Brazilian laws. These P sources were furnished in sufficient quantity to allow a diary ingestion of 4. In order to become the P sources available to the animals through the dry matter intake, it was propitiated 0. The diet was composed by soybean hulls, hydrogenated fat, corn gluten meal, urea, hydrolyzed sugarcane bagasse, together with the P sources that are presently evaluated in this work Table 2.
The furnishment of the diet was propitiated ad libitum and in suitable quantity, being the ingestion adjusted through the evaluation of the excess that remained in the pen.
These diet ingredients above mentioned were chosen due to their low levels of phosphorus, which would favor a more consistent analysis focused on the phosphorus deposition originated by the sources studied in the present work. The diet was elaborated in order to generate weight gain of approximately 0. The complete diet was furnished to the animals at and hours in the same quantities. The sources that were the "test sources" were available only in the morning treatment, being disposed upon the ration with the objective of to guarantee the total ingestion by the individuals.
The period of experimentation was days. It is important to notice that the great interval of time to experimentation does not any relationship with the productive potential of the animals and with the production system. This option was preferred in order to evaluate the effect of the biological accumulation in a significant interval of time, which is a characteristic phenomenon of heavy metals. In the final of the experimental period, after 18 hours of fasting weight, four animals for treatment were slaughtered.
