The objective of this study was to evaluate intake, performance and nutrient digestibility of sheep supplemented with sugarcane ensiled with four levels of calcium oxide (0.0, 0.8, 1.6 and 2.4%) and urea (1.5%), on a natural matter basis. Twenty castrated Santa Ines lambs with 24.09 kg average weight were housed in individual 1.5 m2 pens, distributed in a completely randomized design. The diet supplied had a roughage:concentrate ratio of 70:30 and the experimental period lasted 77 days, of which 14 […]

The objective of this work was to evaluate the effect of sugar cane treated with calcium oxide (CaO) on ingestive behavior in goats. It was used eight castrated male Saanen goats, with 22.6 kg average body weight and at four months of age, distributed in two 4 × 4 Latin squares, with four 14-day experimental periods. The animals were kept in individual 1.2-m2 stalls, with wood battened floor, provided with individual feeders and drinkers. The diets were formulated to be […]

In order to evaluate the use of urea nitrogen, the balance of nitrogen (15N) in Brachiaria brizantha pastures was obtained when urea was applied either incorporated or in the soil surface (in four applications beginning in November of 1998) and the lime was applied in two periods (March and August of 1998). The recovery and retention of the N-urea were obtained for each plant structure of the soil-pasture system, and indicated that the plant crown is a very important storage […]

ABSTRACT – A field experiment was conducted to determine the effect of acid soil correction, on the control of the sapé (Imperata brasiliensis), a grass type weed of pasture. A molasses grass (Melinis minutiflora) pasture in a red-yellow latosol, having a high proportion of “sapé” was used. Treatments consisted of five levels of dolomite limestone (0, 1, 2, 4 and 6 t/ha) incorporated by hand using a garden tool to the top 20 cm of soil following a mechanical tillage […]
