Mineral nutrition of beef cattle grazing native pastures on the eastern plains of Colombia



Mineral nutrition of beef cattle grazing native pastures on the eastern plains of Colombia



Journal of Animal Science 51(6): 1249-1260



Investigations were conducted on the savanna grasslands area of the Eastern Plains of Colombia to determine the mineral status of the native pastures (Trachypogon and Andropogon) and the effect of mineral supplementation on 4 herds of 30-35 grazing Zebu cows. Two herds were supplemented with salt (NaCl) only, and 2 herds were supplemented with a mineral mixture consisting of NaCl, dicalcium phosphate and trace minerals (Fe, Cu, Co, Zn, Mn and I). One herd on the mineral mixture and one on the salt treatment received a urea-molasses-S supplement during the dry season. This treatment had only a minimal effect. Hand-plucked pasture samples indicated that after the pasture was burned N, P, Na, Mn and Co (P < 0.01) and Cu K (P < 0.05) levels were higher in the dry season than in the rainy seasons. Ca and Mg levels in pasture samples were higher (P < 0.01) in the early rainy season, while Zn level was lowest (P < 0.01) in the late rainy season. Levels of Mo and in vitro organic matter digestibility of pasture samples were not influenced by season. Supplementation with the mineral mixture increased live weight of cows and calf weaning weight and tended to increase calf weaning percentage. The mineral mixture also increased (P < 0.01) serum Pi of cows, with the degree of the increase depending on the season. The mineral mixture increased (P < 0.05) liver Co and tended to increase liver Cu but decreased liver Mo when compared to the salt supplement. The amounts of P and Na and, in some instances, Ca and Cu were insufficient for optimum beef production in the Colombian Eastern Plains area.
