Description
This review deals with the potential for beef production from nitrogen- and legume-based pastures in tropical Brazil. Possibilities for imprving the beef industry supported by grass-legume pastures are very promising. According to the literature examined, legume-based pastures produced an annual average of 329 kg gain/ha, and nitrogen (N) fertilization resulted in 4.56 kg gain/ha. Phosphorus (P) was the main fertilizer utilized in addition to N, followed by potassium (K), lime, and micronutrients. Annual rainfall averaged 1430 mm. Grasses used were of the genera Melinis, Hyparrhenia, Panicum, Cenchrus, Digitaria, Cynodon, Brachiaria, and Pennisetum, and the legumes were of the genera Macroptilium, Centrosema, G?,cine, Stylosanthes, Leucaena, Galactia, Calopogonium, and Cajanus. Animals used were Zebu, predominantly of Nelore breeding, and Zebu x European. Results are also presented for she-goats and ewes in semiarid northeastern Brazil. High rainfall and the use of phosphate, other mineral nutrients, and locally adapted grasses and legumes contribute to greater live-weight gain.
