ABSTRACT Integrating warm-climate forage legumes into grass monocultures has received significant research attention during the past 70 years, but widespread adoption by end users has been elusive. The objectives of this review are to provide historical context regarding legume use in warm-climate grasslands; synthesize the current literature addressing contributions to grassland ecosystem services of warm-climate, grass-only vs. legume-grass mixed swards; and consider how to achieve more widespread adoption of legume technology in warm climates. For this review, warm-climate grasslands are […]

ABSTRACT This study examined the replacement of maize and soybean meal with cassava chips and alfalfa grazing, respectively. Twelve lactating Anglo-Nubian goats were kept on a Panicum maximum cv. Tobiatã pasture. The experiment was laid out in a Latin square design in which the following diets were tested: ground maize + soybean meal, cassava chips + soybean meal, ground maize + alfalfa grazing, and cassava chips + alfalfa grazing. The evaluated variables were feed intake, daily weight gain, milk yield […]

This study aimed to evaluate the dynamics of the association of ‘capim-de-raiz’ (Chloris orthonoton Doell) and alexandergrass [Brachiaria plantaginea (Link) Hitchc], as for persistence and production. Gathering of botanical material, evaluation of botanical composition and forage mass were realized in deferred native pastures. To estimate forage mass, a randomized block design with four treatments was used, consisting of 60, 90, 120 and 150 days of deferring and five replications. The botanical composition was expressed as a percentage of the total. Ten […]

The present study aimed to assess the effect of supplementation on the performance of F1 (Boer × females of no defined breed) goats finished in native pasture. The experiment was conducted at the Universidade Federal de Campina Grande, Patos Campus, Paraíba, Brazil, with twenty-four 120-day-old non-castrated F1 (Boer × NDB) male goats, with a 15.52 kg live weight (LW). Animals were distributed in four levels of supplementation (0.0; 0.5; 1.0; 1.5% of body) and six replicates. In order to perform […]

This research was carried out at to evaluate the variability and heritability of morphologic traits in 54 elephant grass clones (three local controls and 51 from the RENACE/CNPGL) in the Forest Zone in Pernambuco. It was used a complete randomized block design with additional controls. Three cuts were performed on the 60th day of regrowth. There were significant differences for stem diameter, basal and aerial tillers density, width of leaf 3, length of leaf 5, leaf blade percentage, stem percentage, […]

The morphological characteristics of perennial ryegrass (Lolium perenne cv. Nui), cocksfoot (Dactylis glomerata cv. Vision) and red clover (Trifolium pratense cv. Pawera) in response to four shade levels (0, 25, 50 and 75%) and two shade patterns (continuous and alternate) were assessed in three growth periods (establishment, first regrowth and second regrowth), in New Zealand, to evaluate the adaptation of different species to changes in the light environment. The experiment was conducted in a randomized complete block design, with three […]

This experiment was carried out from July 2006 to June 2007. It was used an experimental design of random blocks with split plot in time, with two replications using the following treatments: Coastcross + peanut forage + 200 kg/ha of N; Coastcross + Peanut Forage + 100 kg/ha of N; Coastcross + 200 kg/ha of N and Coastcross + Peanut Forage in the following seasons: winter, spring, summer and autumn. To estimate the forage mass production availability, the double sampling […]

The experiment was conducted in a greenhouse and aimed to evaluate the effect of N and P fertilization on dry matter (DM) production of shoots and roots, crude protein (CP) production and concentration, and neutral detergent fiber (NDF) concentration of Tanzania grass. It was used a completely randomized experimental design in a 4 × 2 factorial scheme, being four N doses (0, 50, 100, and 150 mg N/dm3) and two doses of P2O5 (0 and 45 mg P2O5/dm3), with four […]

The effect of nitrogen on the root system of the species Panicum maximum Jacq. cv. IPR-86 Milênio, under grazing, was evaluated. The N rates were 0; 150; 300 and 450 kg/ha.year. The root density was evaluated during pre-grazing at five years of successive N application, in three depths (0-10; 10-20 and 20-40 cm) and the root growth at 7, 14, 21, and 35 days after grazing. The grazing method adopted was rotational stocking. Root length and root mass densities in […]

The objective of this work was to evaluate the supplementation of ewes 30 days before lambing, of the weaning age (45 or 60 days) of lambs and of the finishing system (on confinement – full diet or hay) or in grass on the profile of Tríceps brachii muscle fatty acid of no castrated male lambs. The animals were slaughter with 30 kg body weight or at 150 days-old. The lambs finished on confinement fed were slaughtered by age and the […]
