The dicalcium phosphate is obtained through the citric acid, which in turn is rooted in rock phosphates. The more this is pure rock, the higher the quality of the acid caused it. It is known that the igneous rocks are more pure that the metamorphic, which are more pure that the sedimentary rock. As an example of igneous rocks have the Rock of Cajati (Mountainous); metamorphic - Rock of Patos de Minas, and sedimentary - rock on the African Continent.

The rocks then, through reactions, give rise to citric acid, commonly known as phosphoric acid. The citric acid in turn, after desfluorizado, reacts with limestone or lime and gives rise to the orthophosphate dicalcium, popularly known as dicalcium phosphate.

In the process of manufacture of dicalcium phosphate, there are two main raw materials:

• Phosphoric acid (H3PO4);
• Source of calcium (Ca) as a basis neutralizing, which may be limestone, lime or hydrated lime.

Following are some characteristics of the product through each route:


1) Cal Virgin Phosphoric + Acid phosphate - dicalcium phosphate + Water

You can find dicalcium phosphate with excess of lime does not react, causing serious inconvenience to handle and may cause reactions in the mucosa of the mouth of the animal.


2) hydrated lime + Phosphoric Acid - dicalcium phosphate + Water

Some products with hydrated lime over-hang are found with the pH fairly basic. If you have free lime in excess may have difficulty in handling.


3) Limestone + Phosphoric Acid - dicalcium phosphate + carbon dioxide + Water

All products obtained this way have not reacted limestone, which can be easily identified by the addition of an acid all the Decomposing material on the limestone generating carbon dioxide. In this case the excess of lime not reacted not back any inconvenience and still maintain the balance of product longer.

Any minerals produced with dicalcium phosphate produced from limestone (as in the example 3), when exposed to an acid, will react and release carbon dioxide (causing a characteristic reaction - like a boil).

Otherwise, when you add acid to a mineral mix and it does not release carbon dioxide, one can infer that it contains dicalcium phosphate produced from lime or hydrated lime.

Thus, the fact of the reaction characteristic of release of carbon dioxide in a mineral mix does not mean that the product has not quality, by contrast is a product of greater stability and phosphorus with high quality.

The search for greater profitability in the meat-producing farms in Brazil must be a constant, because the farms have a high profitability (earnings and expenses), but low profitability (earnings / equity), since the property involved in the system production is very high. Thus, increasing the weight gain of animals is essential to the enjoyment has increased and with this increase in profitability.

The high consumption of protein supplement, also known as a supplemental energy is one of those new technologies that demonstrate the creativity of the sector of production (technical and pastoralists), with lower costs because it is possible to fatten cattle in full season. Thus, for the termination of oxen, this is an applied technology where it aims to increase up to 90 kg in the off-season. Therefore, systems that animals with 500 kg, for example, need not confine or semi confine animals between 420 kg and 460 kg, as they can be slaughtered with the use of high-protein consumption and time of year for the best values arroba (October).

High consumption of protein supplements are those which provide between 2 and 4 g / kg of body weight, so an animal of 420 kg will consume around 1200 to 1600 grams per day.

The relationship between the cost and benefit of such supplementation depends on the value of sales of meat (U.S. $ / @) and also the weight gain. Figure 1 shows the earnings per head in the most dry period (150 days) that an animal can have in relation to the mineral supplementation with salt. Depending on the value of the snail sold that profit could be higher or lower. Thus, for a value of arroba of $ 50.00 if the animals are gaining 500 g / head / day more than it would gain in just a supplementation with mineralized salt, shows that the additional income would be around U.S. $ 55.00 / head, on the other hand, the same gain for an arroba of $ 60.00, the profit would be about U.S. $ 75.00. But what the gain that promotes that product?

The Bellman Animal Nutrition has a line of high-protein consumption, these are BellPeso S and BellPeso V. The latter recommended for the summer, will not be reviewed in this article. The correct use of these products has increased the performance of growing and fattening animals in 400 g / head / day.

Weight gain in more than 400 grams per head per day means that for an arroba of $ 50.00, the additional income will be $ 50.00 / animal in the dry period (150 days). This value is interesting to be examined when it is inserted into the production system. For a batch of 1,000 animals would generate U.S. $ 50,000.00 to more than net income.

Another way to analyze the technical cost of protein supplement is in relation to profit discharged at the end of the year on capital invested. Whereas a farm managed well without the introduction of fertilizer has a gross profit of $ 100.00 / animal.ano and that Manning is 2 animals per hectare which we see the introduction of protein supplementation promote additional earnings of $ 100.00 / ha.year, from R $ 200.00 to $ 300.00 / ha.year of gross profit. If the invested capital in 1 ha is $ 3000.00 (U.S. $ 2000.00 for land and cattle from U.S. $ 1000.00) we have that profit on equity rises from 6.7% to 10%.

The protein supplement for livestock on grazing has been increasingly used during the drought. At that time the quality of the plant is small and therefore forage animal performance is lower.

Several other techniques to supplement animal has been adopted with the intention to live with the seasonality of production from tropical forages. Among these techniques, we can cite the semiconfinamento and confinement. Moreover, other technologies of power have been in evidence which are the energy supply of food in drought and more recently in the waters. However, none of these are more economically viable that the protein supplementation of low consumption in the drought.

The low consumption of protein supplements are those that provide up to 1 gram of product for each kilogram of body weight, so an animal with 300 kg consume around 300 grams of product.

The relationship between the cost and benefit of such supplementation depends on the value of sales of meat (U.S. $ / @) and also the weight gain. Figure 1 shows the profit per head more in the period of drought that an animal can have in relation to the mineral supplementation with salt. Depending on the value of snail sold that profit could be higher or lower. Thus, for a value of arroba of $ 50.00 if the animals are gaining 300 g / cabeça.dia more than just benefit from a supplementation with mineralized salt, shows that the additional income would be $ 45.00 / head, on the other hand, the same gain for an arroba of $ 60.00, the profit would be $ 65.00. But what won that promote these products?

The Bellman Animal Nutrition has a line of low-protein consumption to dry, these are Lambisk S, P and Lambisk M. Lambisk The latter launched more recently and that has to complete the family of Lambisks of drought. The correct use of these products has increased the performance of animals, growing at 200 g / head / day.

Weight gain of more than 200 g / head / day means that for an arroba of $ 50.00, the additional income will be $ 25.00 / animal in the dry period (150 days). This value is interesting to be examined when it is inserted into the production system. For a batch of 1,000 animals would generate U.S. $ 25,000.00 to more than net income.

Another way to analyze the technical cost of protein supplement is in relation to profit discharged at the end of the year on capital invested. Whereas a farm managed well without the introduction of fertilizer has a gross profit of $ 100.00 / animal.ano and that Manning is 2 animals per hectare which we see the introduction of protein supplementation promote additional gains of $ 50.00 / ha.year, from R $ 200.00 to $ 250.00 / ha.year of gross profit. If the invested capital in 1 ha is $ 2000.00 (U.S. $ 1000.00 for land and cattle from U.S. $ 1000.00) we have that profit on equity rises from 10% to 12.5%.
