The research was conducted at the EMBRAPA – National Center for Goat Research, in Sobral, Ceara, Brazil, to evaluate the effects of cutting of the above ground parts in relation at regrowth height of marmeleiro on its survival, persistence, regrowth vigor and subsequent production of herbaceous understory phytomass. The plants were cut at 10.0 cm above ground, when the regrowth reached four different heights (25, 50, 75 and 100 cm). The cutting treatments were applied on plots of 5 m […]

The experiment was conducted to evaluate the changes on the nitrogen compounds of the Brachiaria decumbens Stapf, jaraguá (Hyparrhenia rufa Ness Stapf) grasses hay, untreated, treated with urea (5.4% DM), urea plus lab-lab (UL-5.4% DM plus Lablab purpureus L. Sweet, cv. Highworth-3.0% DM) and anhydrous ammonia (NH3 – 3.0% DM). The chemical treatment with urea or NH3 increased the total N, neutral detergent insoluble N 9NDIN), acid detergent insoluble N (ADIN), non nitrogen protein (NNP), and the ammonical nitrogen (AN) […]

The trial was carried out from August/1997 to April/1998, aiming to evaluate Coastcross-1 (Cynodon dactylon (L.) Pers) grazed pasture, at four levels of dry matter residue (DMR: 1978; 2130; 2545; 3857 kg of DM/ha) under continuous stocking grazing with variable stocking rate in relation to dry matter production (DMP), pasture growing rate (GR), net accumulation rate of DM (LADM), plants height (PH), uncovered soil percentage (NS), participation of botanical components in percentage of dead material (DDM) and green leaves (GL), […]

The experiment was conducted from October 1997 to April 1998, to evaluate the nonstructural carbohydrates (SC), total nitrogen (TN) and roots weight, of the pasture of Coastcross – 1 (Cynodon dactylon (L.) Pers), under four levels of dry matter residue (DMR: 1978, 2130, 2545 and 3857 kg DM/ha), under continuous stocking (put and take). A completely randomized design, with two replications, was used. SC and TN contents were analysed on roots and stem base according to dry matter residue levels […]

An experiment was conducted to evaluate the effects of different combination of levels of ammonia (0.0, 2.2, 3.2, 4.2% by weight of dry matter) and sodium sulphide (0.0, 2.1, 3.1, 4.1%) on chemical-bromatologic composition and “in vitro” dry matter digestibility (IVDMD) of coffee peel with 30% of moisture. The crude protein (CP) content increased due to the crescent levels of anhydrous ammonia. The nitrogen retention (NR) decreased as the ammonia and sulphide levels increased. The contents of insoluble nitrogen in […]

Chemical composition and the in vitro dry matter digestibility were evaluated in blades and stems at two stages of development and two insertion levels on tillers of signalgrass (Brachiaria decumbens), molassesgrass (Melinis minutiflora) and tifton 85 bermudagrass (Cynodon sp), in two seasons of the year (summer and autumn). Lower and upper leaf blades were sampled from the tillers, on the day of ligule exposure and 20 days thereafter, and stems segments located below of the upper leaf blade. The crude […]

Leaf blades and stem segments at two stages of development (day of leaf ligule exposure and 20 days thereafter) and two insertion levels on tillers (lower and upper) of signalgrass (Brachiaria decumbens), molassesgrass (Melinis minutiflora) and tifton 85 bermudagrass (Cynodon sp), were sampled in two seasons of the year (summer and autumn). The anatomical and chemical traits, and in vitro dry matter digestibility of blades and stems segments were evaluated. The correlations among these variables were established to associated values […]

Nitrogen and sulfur fertilizations were evaluated in a native low-land pasture area (Planossolo) in southern Brazil, state of Rio Grande do Sul, for dry matter yield and crude protein contents, between Oct. 1996 and Mar. 1997. In a factorial treatment arrangement six levels of sulfur (0, 10, 20, 30, 40 and 50 kg/ha) were combined with four levels of nitrogen (50, 100, 150 and 200 kg/ha) topdressed to the pasture in Oct. 10, 1996. Two cuttings were made to determine […]

The trial was carried out from August/1997 to April/1998 to evaluate a Coastcross-1 (Cynodon dactylon (L.) Pers) grazed pasture, under four dry matter residue levels (DMR: 1978; 2130; 2545; 3857 kg of DM/ha), with continuous grazing and variable stocking rate. Chemical composition, as crude protein (CP), neutral detergent fiber (NDF) and acid detergent fiber (ADF) contents, in vitro dry matter digestibility (IVDMD) and ewes performance were evaluated. A complete randomized design with two replications was used. CP content in forage […]

Lambs performance fed on creep feeding and fedlot were evaluated at two experiments. In the first experiment, thirty two 3/4 Suffolk lambs were fed on creep feeding, weaned at 56 days of age and, after, were confined. Lambs were fed four different treatments: 1. without supplemmentation; 2. supplemmentation with ground corn and soybean meal; 3. ground corn, soybean meal and 15% alfalfa hay; 4. ground corn, soybean meal and 30% alfalfa hay. After weaning, lambs that received concentrate supplemmentation were […]
