Brachiaria humidicola is well adapted to infertile and acid soils with poor drainage or temporary flooding (Keller-Grein et al. 1996). It is widely used in Brazil in wetlands and areas of marginal land characterised by waterlogged soils. During the evaluation stages of the breeding program of this species, genotypes are generally tested using consecutive cuts within different seasons for at least 2 years. The ‘Cerrado’ region, where most animal production takes place in Brazil, has 2 well defined seasons: spring-summer with warm weather and rain; and autumn-winter with cooler, dry weather. Thus, owing to environmental variation, especially related to …
Effects Of Irrigation And Season On Performance Of Grazed Pastures Of Brachiaria Brizantha Cv. Mg5, Rita De C. R. Carvalho, Wellington W. Rocha, Bruno S. Pires, César T. Piza, Luziney D. Silva, Paulo R. V. Leite, Eliel A. Ferreira
Effects Of Irrigation And Season On Performance Of Grazed Pastures Of Brachiaria Brizantha Cv. Mg5, Rita De C. R. Carvalho, Wellington W. Rocha, Bruno S. Pires, César T. Piza, Luziney D. Silva, Paulo R. V. Leite, Eliel A. Ferreira
IGC Proceedings (1997-2023)
In Brazil, livestock production is based primarily on systems with continuously grazed natural or cultivated pastures (FAO 2009). Intensifying animal breeding, handling and knowledge strategies is necessary to obtain improvements in production indices for economically feasible and sustainable grazing systems (Cedeño et al. 2003). Beef cattle breeding on irrigated pasture, like all forms of intensive grazing, requires the use of forage species with high potential for production and quality, and Brachiaria brizantha cv. MG5 is considered a good option. This study aimed to evaluate the effects of irrigation on the performance of B. brizantha cv. MG5 grazed rotationally by …

Brachiaria Hybrids: Potential, Forage Use And Seed Yield, Esteban A. Pizarro, Michael D. Hare, Mpenzi Mutimura, Changjun Bai

A brachiaria breeding program initiated in 1988 at CIAT (Centro Internacional de Agricultura Tropical) combined desirable attributes found in accessions of Brachiaria brizantha and B. decumbens. Three apomictic hybrids have been released (cvs. Mulato, Mulato II and Cayman). Mulato showed agronomic potential but seed yields were low. Trials in Central America demonstrated the superiority of Mulato II, a vigorous grass with very deep and branched roots, giving it excellent drought resistance in the Brazilian Cerrado and Mexico. Mulato II has excellent nutritional value. Following trials in Mexico and Thailand, evaluating 155 new hybrids for 7 years, cv. Cayman was …
