A breeding program to select low-mimosine lines of leucaena has been in progress since 1970. Selections were evaluated in two field trials at Lansdown. Although the low-mimosine selections did indeed have lower mimosine than the control cultivars, their dry matter yield was also inferior (about t...

The area of forest plantations in the tropics worldwide is increasing as a response to the expansion of degraded lands. Rural farmers of many regions of the dry and humid areas are responding to government and other incentives, dedicating portions of their land to native and exotic tree plantatio...

Twenty five rumen fistulated Ethiopian Menz sheep were used in a completely randomized block design to determine roughage utilization when different types of supplements (sesbania, leucaena, cotton seed cake (CSC) and forms (fresh or dry leucaena) were fed. The chemical composition, intake, diges...

In vitro gas production, dry matter and nitrogen degradabilities of fresh and sun-dried foliages of four fodde trees (FTs) (Sesbania sesban, Leucaena leucocephala, Chamaecytisus palmensis (tagasaste), Vernonia amygdalina) and of teff straw were estimated. In Experiment 1, feed samples were incuba...
