The effect of feeding increasing levels of Leucaena leucocephala leaf hay on the potential fertility and feed intake of male highland sheep maintained on roughage diet was studied. In treatment 1 (NS), animals received only chickpea haulm. Treatments 2 (L100), 3 (L200) and 4 (L300) consisted of 1...

This study tested the hypothesis that purebred Boran (Bos indicus) cows and crossbreds of Boran and Holstein respond differently to long-term changes of feeding level in nutrient partitioning to milk and body fat stores. A total of 27 cows of these two genotypes were subjected either to a low or ...

The aim of this study was to characterize growth and sperm production parameters in Ogaden bucks fed a basal diet of hay and supplemented with agro-industrial by-products and Khat leftovers in Ethiopia. Thirty-five bucks with a mean (±SD) initial live body weight (BW) of 15.5 ± 1.5 kg were random...

The experiment was conducted at Debre Zeit Research Station of the International Livestock Research Institute in Ethiopia for 126 days. Fifty-four male Menz sheep with initial live weight (LW) of 15.7+/-0.32 kg (mean+/-S.D.) were blocked on initial LW and randomly assigned to one of the nine tr...

The research was conducted at the International Livestock Research Institute's Debre Zeit Research Station in Ethiopia. Leucaena pallida 14203, Sesbania sesban 1198 and Lablab purpureus were grown, harvested and dried at the research station. Seventy individually penned Menz ewes with a mean ini...

A study was conducted to evaluate the effect of supplementing levels of Leucaena leucocephala leaves on reproductive capacity and growth of male highland sheep (Arsi type) in Debre Zeit Research Centre. Animals were randomly allotted to one of five experimental rations. In treatment 1 (NS) animal...

Most supplementation experiments with fodder trees including S. sesban have been of short duration and focused mainly on feed intake and growth rate. Long-term studies regarding the effects of feeding S. sesban on reproductive performance of sheep particularly in both sexes are scanty. This study...

Two successive experiments were conducted to investigate the long-term effects of supplementation of Sesbania sesban on reproductive performance of Ethiopian Menz sheep. Forty ewes and 40 rams ranging in weight and age between 16–20 kg and 14–15 months respectively were fed a teff straw basal die...
