| This experiment was carried out with the objective of determining the macrominerals (Ca, P, Mg, K and Na) requirements of Nellore steers under grazing. Twenty four Nellore steers (371 ± 14 kg of BW and 26 mo old) were used. Four steers were slaughtered at the beginning of the experiment (reference group), serving as a reference in subsequent study. The remaining 20 animals were weighed and distributed into a completely randomized design with four supplementation levels offer: 0.0 (mineral mixture - control), 0.3, 0.6 and 0.9% of BW, with five replications. The supplements, based on ground corn, soybean meal and/or urea, were previously balanced to achieve an average daily gain of 350, 650 and 850g, respectively, for the different supplementation levels... |

| ABSTRACT This experiment was conducted to investigate the effects available phosphorus levels and dicalcium phosphate particle size on the live performance, and egg parameters and bone parameters of Japanese quails in lay. The experimental diets were based on corn and soybean meal and formulated to contain 2900 kcal metabolizable energy (ME)kg-1, 200 g kg-1 crude protein (CP) and 30.5 g kg-1 calcium (Ca). Feeds were supplied ad libitum. Laying Japanese quails (n=720, 20-wk-old)were distributed in a completely randomized design in a 5 x 2 factorial arrangement, with five levels of available phosphorus (avP; 1.0, 2.0, 3.0, 4.0, 5.0 g kg-1) and two dicalcium phosphate particle sizes (fine orcoarse), totaling ten treatments with eight replicates of nine birds... |
