Description
To evaluate and select the best branching heights and the leucaena ecotypes which give the best supply and consumption of dry matter, an experiment was carried out at the “Judibana” ranch near El Vigía, Mérida State, Venezuela, at an altitude of 65 meters (165 ft.). The experimental design used was random blocks and the treatments were in a split plot design, repeated three times. The main plots were 13 leucaena ecotypes (CIAT - 7385, 7984, 7985, 9377, 17217, 17218, 17219, 17222, 17223, 17474, 17492, 17501, 17502) and the secondary ones were three heights of branching (0.40, 0.80 and 1.20 m). Grazing with lactating cows took place every 45 days. The results indicated that the ecotypes do not differ significantly for the variables under study. However, for branching height, the variance analysis showed significant differences (P < 0.01). It was concluded that the best height was 1.20 m. where the best values for supply, residues, forrage consumption, as well as height and number of branches were obtained.
