| The experiment was conducted to evaluate the addition of phytase on productive performance and egg quality of Japanese quails fed diets containing different levels of phytase. It was used 320 Japanese quails at 167 days of age, weighing 182.3 ± 3.8 g distributed in a completely randomized design with four experimental diets and eight repetitions of ten birds per experimental unit. Diets were formulated from a basal diet (control) and they were corn and soybean meal based, without supplementation, added with 200, 400 or 600 phytase activity unit (ftu). Supplementation of phytase in the diets improved productive performance and quality of eggs. Efficiency of phosphorus use for egg mass, from 0.13% of availability of this mineral in the ration, improved with... |

| ABSTRACT Studies were conducted to determine the effects of different ensiling densities on fermentation, aerobic stability, and nutritive value of maize and sorghum silages. Maize and sorghum were harvested at dough (363 g/kg) and milk stages (275 g/kg), respectively. Herbages were chopped approximately 1.5 cm after harvest and then ensiled in mini silos at high and low-bulk densities for 8.5 weeks. Different bulk densities were achieved by ensiling different weights of herbage in the fixed-volume mini silos (1.5-L anaerobic jars, Weck, Germany). The obtained dry matter (DM) densities were 168 and 216 kg of DM/m3 for maize forage and 132 and 178 kg of DM/m3 for sorghum forage. Fermentation kinetics, the rate of aerobic deterioration upon aerobic exposure,... |
