This experiment was conducted aiming to verify the effect of four levels of calcium (Ca) and available phosphorus (aP) in the diet on the performance, quality of eggs and the mineral excretion in Japanese quails during the final third of the production cycle. A total of 384 quails at 313 days of age was used. They were distributed in a complete random design in a 4 × 2 factorial scheme composed of four levels of calcium (2.0, 2.5, 3.0, and […]

The objective of this experiment was to evaluate the food intake, food conversion and weight gain of Braford calves, weaned with 88 days of age, fed with triticale silage associated to 35, 45, 55 or 65% concentrate, dry matter basis. The animals were fed ad libitum, twice daily with the 15% CP diet. The experiment was conducted during 84 days, divided in four periods of 21 days. Average daily intakes of dry matter (DMI) expressed in kg (DMID), per 100 […]
