Cattle grazing under Pinus caribaea. 1. Evaluation of farm historial data on stand age and animal stocking rate
An analysis is made of the animal stocking rate used in commercial Pinus caribaea plantations 2,5-8,5 yr old. Pines were planted at 2,5 x 2,5 m and programmed for clear-cut harvest at 10 yr rotations (pulpwood). Cattle grazing was introduced to reduce weeding costs. Stocking rate in 1983-1985 was 0,67 AU/ha/yr (AU = animal units 350 kg live weight). A quadratic model calculated using 1984 data (S = 0,0108 + 0,385A-0,0418Aø) describes the relationship between animal stocking rate (S) and stand age (A < 9,5 in yr). The model predicts a maximum of 0,89 AU/ha/yr at plantation age 4,5 yr. Grazing started at plantation ages > 2,5 yr; no plantations older than 9,5 yr are grazed.
