Five hundred and four 1-day-old Cobb broiler chickens were randomly allotted to 18 treatments and fed a semi-purified basal diet (4 g/kg total phosphorus) supplemented with 2 levels of supplemental P (0.5 or 1 g/kg) during 21 days to evaluate performance and bone mineralization; to assess the relative bioavailability of P (RBP) in wheat meal (WM) and roasted (RS) or extruded soybean meal (ES), with or without phytase (0 or 750 ftu/kg diet), using dicalcium phosphate (DC) as standard; and […]

This experiment aimed at evaluating the productive performance, intake and the apparent digestibility in the raising of beef heifers on Brachiaria decumbens Stapf. pastures under supplementation with starch or fibrous energy sources during the dry season. It was used 40 newly weaned heifers (20 Nellore and 20 crossbreed), at 8.5 months of age and 197.9 ± 3.74 kg initial weight. Two supplements were formulated: the first was corn meal- and soybean meal-based diet (high in starch) and the second was […]

The aim of this study was to check on the effect of additive addition on the variations in the water soluble carbohydrate contents of the tanzaniagrass silage during the fermentation period, and to know the buffering capacity values and water soluble carbohydrate: buffering capacity ratio of this forage. Tanzaniagrass (Panicum maximum Jacq. cv. Tanzânia I) was established in a Clavey Red Dusk Latosol and harvested at 60-65 day of age. The forage was ensiled in experimental PVC silos, fitted with […]
